Cannabinoids, chemical compounds found in the cannabis plant, are naturally fat soluble, meaning they are dissolvable only in nonpolar solvents and, thus, not capable of mixing with water. It’s a major problem that often makes the manufacture of cannabis-based beverages difficult since cannabinoids can’t be broken down and mixed with other ingredients naturally for any sustained amount of time. Cannabis-based beverage products, for instance, work faster, taste better and last longer only when they are able to be mixed properly with — read: dissolved completely within — other ingredients. Leaving cannabinoids in their original oily state, then, makes it impossible to guarantee the bioavailability, stability or longevity of cannabis beverages. Luckily, manufacturers have options. Here’s how you can create water soluble cannabinoids for beverages and, therefore, always ensure that your cannabis drinks are of the highest quality:

What are Water Soluble Cannabinoids for Beverages?

Technically, there are no “true” water soluble cannabinoids. What we actually mean when we use the term “water soluble cannabinoids for beverages” is really just “cannabinoids that have been reduced to the smallest-sized particles so that they can be thoroughly mixed with a liquid substance.” With this in mind, the trick becomes finding a way to break down cannabinoids into such small pieces that they can be used to manufacture cannabis beverages with maximized flavor and potency.

Using Emulsions to Create Water Soluble Cannabinoids for Beverages

As mentioned, if cannabinoids are left in their natural state, cannabis-infused drinks would need to be shaken and then immediately consumed. It’s not unlike an oil-based salad dressing that has to be shaken before used. This is never ideal, however, since shaking a product can actually degrade it: carbonated drinks lose their bubbles, for example, or ingredients get unevenly distributed, making the drink taste funny, look cloudy and/or rendering it unable to provide a consistent dose of active ingredient(s). Furthermore, because the cannabinoids are still basically fat molecules which have been only temporarily suspended in a liquid, the body must still process them through the digestive system, a much longer process compared to that of water soluble cannabinoids dissolving directly into mouth, stomach and intestinal tissues. 

To solve the problem, manufacturers need to create water soluble cannabinoids via emulsification. Emulsification is the process by which normally immiscible substances are mixed together so that separation can’t occur. There are several different types of equipment that can facilitate emulsification, but the most effective and efficient one is a BEE International high pressure homogenizer. BEE stands for Best Emulsifying Equipment.  Our high pressure homogenizers create stable emulsions that guarantee water soluble cannabinoids for beverages each and every processing run.

The BEE International Advantage

Most emulsifying processing equipment utilizes only one or two forces to physically break apart and mix samples. BEE International high pressure homogenizers, however, utilize a combination of forces, including turbulence, shear, cavitation, impact and high pressure, that more forcibly reduces a sample’s particle size, creating larger surface areas to which bonding can occur. The result: shelf stable mixtures with increased potency and bioavailability. In addition, our patented mixing technology eliminates the need for pre-mixing and includes customizable options for the combination of forces, as well as the intensity and duration of operation, allowing manufacturers to manage the production of water soluble cannabinoids for beverages in the fewest amount of passes, saving them time and money.

How Cavitation is Used in Chemical Engineering

Posted by David Shechter on Aug 27, 2021 2:05:00 PM

Cavitation is the rapid expansion and implosion of vapor-filled bubbles (or “cavities”) within a liquid substance. These cavities form when intense vibration within the liquid breaks its natural bonds and causes its ambient pressure to become lower than its vapor pressure. In many instances, cavitation is seen as a problem, causing functional changes in both natural and manmade processes that make reliable and consistent operational results impossible. In other cases, however, cavitation can be harnessed for specific manufacturing benefit, delivering products that are more effective — in both application and cost — than those made without it. Chemical engineers, for example, rely on cavitation to homogenize particles within colloidal suspensions, thus enabling them to create a wide range of chemical products including polymers, plastics, pigments, paints, pastes, pharmaceuticals and more! Read on to learn how cavitation is used in chemical engineering:

Cavitation is Used to Reduce Particle Size

In many (perhaps even most) chemical manufacturing processes, substances need to be mixed in order to be useful. Thus, first and foremost, cavitation is used in chemical engineering as a way to reduce particle size so that one substance can be more thoroughly combined with another one. Think about it: it’s a lot easier to combine small, uniform pieces than it is to combine large, various-sized ones!

Cavitation is Also Used to Improve Cohesion 

Furthermore, smaller particles mean more surface area; more surface area means more opportunities for particles to interact with one another; and more interaction ultimately yields better — i.e., tighter — cohesion. Because of this, the implosions caused during cavitation inception can be intentionally harnessed during chemically engineered product processing as a way to disrupt the natural bonds of a substance, creating products with a tight distribution of smaller particles that subsequently improve their consistency, viscosity, texture, appearance and even bioavailability (when applicable)!

Indeed, the uniformity of particle size and the cohesion it facilitates combine to provide enhanced product stability, ensuring more effective and a lot longer lasting products than those created in other ways.

The BEE International Advantage

In the chemical engineering world, cavitation isn’t just a problem to be avoided, eroding pumps and interfering with mechanical operations. On the contrary, cavitation can be used for advantage in many chemical manufacturing processes; intentionally initiating cavitation during production allows manufacturers the ability to create extremely effective, reliable and shelf-stable products. And if they use a BEE International high pressure homogenizer, the results can be further compounded.

An Introduction to Creating Colloidal Solutions

Posted by David Shechter on Aug 13, 2021 1:50:00 PM

AdobeStock_224777398

Mixing is an important part of many processes, affecting the quality of numerous man-made (and nature-made) products. In laboratory and manufacturing settings, mixing often determines the overall value of a product, as well; mixed inappropriately, a product could end up being useless, costing scientists and manufacturers alike a lot of wasted time and/or money and offering no significant or effective operational merit. Thus, it’s important to know the different types of mixtures and their associated benefits. In this post, we’re going to discuss colloidal solutions, a type of mixture wherein tiny particles of one substance (liquid, solid or gas) are suspended within another substance (liquid, solid or gas). Here’s what you need to know about colloidal solutions, including how they’re created and what their differences from other types of mixtures mean for the people who use them:

What is a Colloidal Solution?

Multiple kinds of mixtures exist (solutions, suspensions and colloids/dispersions) with each one involving a specific process for its creation. For this blog, we’ll consider a colloid mixture (also commonly called a “colloidal solution” or “colloidal dispersion”), which is a mixture of one substance into another such that neither can be separated from the other. However, unlike a true “solution,” a colloidal solution does not involve the dissolution of one substance into another. Instead, a colloidal solution is comprised of particles that are evenly distributed (but not dissolved) within a substance in such a way that they can not settle nor separate from the medium over time. The key to this type of mixture is ensuring that the substance being dispersed into the associated medium is broken into particles that are small enough that they can be — and will always remain — thoroughly mixed with the medium containing them. Mixtures that don’t remain combined are known as suspensions.

How to Create a Colloidal Solution

The first step in creating a colloidal solution is breaking apart the product to be dispersed into the medium. There are several ways to facilitate this process; chemicals can be used to break apart a product and/or physical force(s), such as agitation, stirring, pounding, grinding, etc. High pressure can also be used, and our team at BEE International believes that our high pressure homogenizers provide the best options on the market when it comes to particle size reduction for colloidal solutions. Our homogenizers combine a variety of forces (high pressure, shear, cavitation and impact) to ensure nano-sized particles result in the least number of passes. These extremely small particles are then able to be fully distributed throughout the medium, thereby effectively creating a colloid solution.

Why Colloid Solutions are Important

Colloids are valuable because they prohibit the separation of two otherwise immiscible products. The milk we drink; the paint we use; the makeup we wear; the drugs we take: these are all example of colloid solutions. Because very small particles have been mixed in just the right way, many of the foods, paints, polymers, pastes, cosmetics and pills (and more) that we consume are able to exist. Mixed properly, they are consistently more stable, lasting longer than they would otherwise, as well as more attractive, remaining fully combined so that they look and feel smooth and cohesive. When applicable, colloids are also better tasting with better bioavailability. These are all important benefits of colloidal solutions.

Creating colloidal solutions is a critical process that affords us with many useful and vital products for everyday life. To effectively disperse products within a medium, manufacturers and scientists need reliable, effective equipment. We believe BEE International high pressure homogenizers (HPHs) offer the tightest distribution of the smallest sized particles in the least number of passes, making them the best option for the creation of colloidal solutions.

High Pressure Homogenizers for Nanomilling for Bioavailability Enhancement

Posted by David Shechter on Jul 16, 2021 2:25:24 PM

unspecified_1Approximately 50% - 90% of existing and potential new drugs are poorly soluble. It’s a statistic with dramatic implications, since poor solubility inhibits the absorption of a drug’s active pharmaceutical ingredient (API), which renders less beneficial effects for the patients who wish to use them and less profitable results for the companies that try to sell them. Recent advancements in pharmaceutical development processes, however, indicate that using high pressure homogenizers for nanomilling dramatically improves the bioavailability of active drug ingredients, thus benefiting individuals and drug companies alike. Take a look:

What is Nanomilling for Bioavailability?

Drugs work better when they have a large surface area available for solvation. Think about a sugar cube dissolving in a cup of tea: a crushed cube will diffuse throughout the cup quicker than a lump. In much the same way, a drug whose active particles have been reduced to their smallest uniform size will disperse throughout the body better than a drug with larger particles.   

Nanomilling, then, is the process by which an API is reduced to particles less than 1000 nm in size. It’s also called wet media milling, and can be effectuated via several different techniques, but we believe high pressure homogenizers (HPHs) offer the most advantages when nanomillling for bioavailability. Here’s why:

High Pressure Homogenizers Minimize Contamination

High pressure homogenizers apply constant pressure to a product to break it into uniformly-size pieces. Other types of particle size reducers (such as bead mills, for example) use an actual grinding material (i.e., beads) to the facilitate particle reduction, agitating this material along with the product so that the product itself breaks apart. We believe HPHs, particularly those with BEE International’s propreitary pressurized pumping system, are far superior to bead mills and other wet media milling technologies specifically because they don’t introduce any foreign materials into the particle reduction process — just high pressure and the active pharmaceutical ingredient —  thus, posing little to no risk for contamination.

High Pressure Homogenizers are Faster

High pressure homogenizers supply a very intense and focused energy that enables quicker particle reduction than other processing methods. They are also highly efficient, enabling optimal particle size in the fewest passes, saving valuable production time and getting drugs — that actually work! — more quickly into the hands of the patients who need them!

High Pressure Homogenizers Allow for Targeted Particle Reduction

Because BEE International’s HPHs utilize a modular system that combines pressure, shear, cavitation and impact, many different configurations can be set up, each according to the specification of the product at hand. This means operators can customize their processes so that the exact particle size needed is produced during each run.

High Pressure Homogenizers Are Consistent and Versatile

The unique combination of forces used in BEE International high pressure homogenizers produces a tighter, more uniform distribution of particles and can be used for both inline and batch processing.

High Pressure Homogenizers Yield Scalable Results

The most beneficial type of processing equipment allows operators the ability to progress from the laboratory to production with no loss of reliability or efficacy. High pressure homogenizers allow customization of the particle size reduction process according to product volume so that the chemical integrity of active ingredient(s) is always the same.

High Pressure Homogenizers Are Easy to Clean

Finally, unlike bead mills and other types of homogenizers, high pressure homogenizers do not require manual cleaning. Inline cleaning processes permit routine (and nearly) hands-free maintenance that is not available with other nanomilling options.

What is Emulsification and How Is It Used to Produce Cannabis Nanoemulsions

Posted by Deb Shechter on Aug 26, 2020 9:15:00 AM

Bee International helps cannabis producers with emulsification to create a superior productThe legal cannabis industry is a multibillion dollar enterprise that rests largely on the quality of the cannabis plant’s active components. Called cannabinoids, these chemical compounds — when effectively harvested and processed — are capable of bonding with receptors in our bodies and have the potential to produce anti-inflammatory, analgesic, euphoric and/or calming effects. Indeed, cannabinoids have been used by humans, both clinically and recreationally, for thousands of years, suggesting they are safe to consume with many beneficial properties.

But just because humans have a history of safely using cannabis products, it doesn’t mean that all cannabis products are created equal. Changes to federal and state laws have decriminalized cannabis use and relaxed criminal mandates in many areas of the country, allowing more and more players to enter the CBD and cannabis market. The result: a plethora of products but few standards. Yes, most states regulate the manufacture of cannabis products, but many lack even minimum requirements for potency, safety and/or testing; consumers are simply at the mercy of manufacturers, hoping they actually get what they pay for.

To better guarantee the quality and effectiveness of their products, reputable manufacturers work to create their own production processes that both sustain and maximize cannabinoid stability and bioavailability and deliver reliable results — in this case, medicines and products that are capable of provoking specific physiological effect(s) — each and every time. They do that by emulsifying the cannabis during production. Here’s how it works:

What Is Emulsification?

Emulsification is the mixing together of two or more substances that wouldn’t normally be able to combine. A chef vigorously whisking oil into vinegar to make a dressing is an example momentarily of a mix, but within seconds separation occurs. Emulsification adds an emulsifying agent, something that successfully binds the oil and water phase together without separation.

Cannabis manufacturers also use emulsification to ensure that the cannabinoids they extract from cannabis plants are able to be incorporated into viable products — drinks, creams, edibles and more that taste, look and/or smell good and that deliver the same results with each production run. The stability of these products, part of which is determined by the length of time the components do not separate, extends shelf life and expiration date.

How Are Homogenizers Used in Cannabis Production?

The process starts with the harvesting of the cannabis plant. From there, a manufacturer must extract the cannabinoids, basically a sticky syrup that is then refined, purified and distilled (or separated) from compounds that aren’t needed, such as terpenes, flavonoids and other contaminants. It is this resulting substance — an oily, bitter isolate that naturally repels water — that necessitates the emulsification process. At this point, the cannabinoid isolate is exposed to mixing equipment that uses one or more forces to break apart the chemical bonds of the cannabinoids and reduce the size of their particles.

Homogenization is the ideal mixing method. It is an in-line process, which means that all particles undergo the same mixing forces and there is less variation in the results. This eliminates “hot spots “in the end product. Homogenization is also an efficient mixing process, which means less time to produce a better effect.

Why BEE International Homogenizers Are the Best at Emulsifying

Typical emulsifiers use only one type of force, but a BEE International homogenizer uses multiple forces (turbulence, cavitation, shear and impact) to break apart and reduce particles. This creates smaller particles, maximizing the surface area of the cannabinoids.

BEE International homogenizers are versatile, with the ability to deliver a gentle mix to the most intense mixing process with up to 45,000 PSI. The intensity breaks product particles into the smallest size, down to nanometers. Smaller particles make it easier for their particles to completely mix, stay mixed with the aid of an emulsifier and deliver a product that is shelf stable and ready to be used. Smaller particles also increase potency and bioavailability up to 75%.

Only BEE International homogenizers have an option to eliminate the need for pre-mixing. This increases the efficiency and ease of the manufacturing process with less equipment and fewer manufacturing phases.

Everything You Need to Know About the Homogenization of Cells

Posted by Deb Shechter on Jan 31, 2020 12:13:15 PM

homogenization of cellsThe homogenization of cells refers to the process by which all components of a biological sample are made equal. By breaking down cell membranes/walls, it allows for the thorough mixing of a sample’s cellular contents. The result: a sample that has a consistent and uniform molecular make-up. Here’s everything you need to know about cell homogenization:

 

The Homogenization Process

The homogenization of cells is basically a cell lysis technique meant to release the intercellular contents of cells so that they can be better accessed, maintained and/or mixed. There are other ways to disrupt (or lyse) cells, such as cryopulverization, nitrogen decompression and more, but the most popular method is homogenization. Homogenization uses one or more types of mechanical force to break apart and mix the components of a sample. When used with biological materials, cell homogenization allows scientists to isolate and study the contents of cells and manufacturers to make better products.

 

Why You Should Homogenize Cells

There are many reasons to choose cell homogenization over other cell lysis methods, the most significant being that different types of cells require different disruption techniques. For instance, some cells are fragile and need a more sensitive means for cell lysis lest the entire cell be destroyed during the process. Some cells have tough outer matrices or walls, warranting a more extreme cell lysis force in order for valuable intercellular contents to be reached. Some cells need enzymes or other reagents added to them to facilitate lysis, and in other cases, the cell lysis procedure itself either creates or relies on a certain temperature that can comprise or otherwise negate optimal results. The considerations are varied and wide-ranging with everything from the cost of the equipment, the size of the sample and stability, reproducibility and scaling problems to even physical space constraints (to accommodate the size of the equipment) also affecting the selection of one cell lysis method over another.

 

The Value of High Pressure Homogenization of Cells

Here at BEE International, we believe that homogenization — specifically, high pressure homogenization — affords the best value for many scientists and manufacturers alike. Our high pressure homogenizers offer a customizable approach to the cell homogenization process, with our patented Emulsifying Cell (EC) technology allowing you to control the type and duration of the force(s) used according to multiple cell types. Indeed, our proprietary homogenizing system can rupture cell walls and membranes without damaging any other crucial cell components, making our equipment effective, efficient and extremely competitive. If you would like to learn more about the homogenization of cells and how high pressure homogenizers can improve your productivity, as well as strengthen the quality of the products you test and create, please contact us. We believe cell homogenization offers countless benefits when used as a part of many research and manufacturing processes.

How to Pick the Right Homogenizer for Colloidal Suspensions

Posted by Deb Shechter on Dec 26, 2019 12:34:22 PM

colloidal suspensionsWhen choosing a homogenizer for a particular application, it’s important to first understand the differences among solutions, colloids and suspensions. Each is a type of mixture, and a mixture is one of the end results of the homogenization process. Thus, picking the right homogenizer directly influences the quality of the mixture you create.

 

What are the Difference Among Solutions, Colloids and Suspensions?

A solution is a homogenous mixture where one substance (the solute) is completed dissolved into another (the solvent). Solutions can be a combination of any two phases (solid, liquid or gas), but they always result in a single, continuous one. A colloid, on the other hand, is a heterogenous mixture with particles that are bigger (1-1,000 nm) than those of a solution (<1 nm) but smaller than those in a suspension; because of their size, particles in a colloid do not allow light to pass through the mixture, instead scattering it back outward in a process known as the Tyndall Effect. They are not so big, however, that they aren’t able to stay fully mixed, with components unable to be separated by filtration, time or rest. Last, but not least, a suspension is also a heterogenous mixture. Its particles are bigger than those found in both solutions and colloids; they are so large, in fact, that gravity is able to pull them down and settle them at the bottom of the mixture when it’s not being actively mixed.

 

What Should You Look for in a Homogenizer for Colloidal Suspensions

Colloidal mills are a type of “rotor-stator” or “high shearmixer specifically designed to work with colloid suspensions. As such, their function is to reduce particle size so that two substances can be mixed together more easily. The shearing force of the spinning rotor effectively disrupts molecular bonds within a sample and reduces particle size. They are most often used for mixing together two liquids, a solid with a liquid and/or highly viscous materials. However, colloid mills can’t be run continuously because they consume large amounts of energy, which could potentially contaminate any resulting product mixture. Thus, instead of assuming that a colloid mill is the only option for use with colloidal suspensions, users should consider a homogenizer that affirms the following questions:

Does it Reduce Particle Size? ✔️

Does it Reduce the Number of Passes? ✔️

Does it Help Preserve the Product? ✔️

 

Unlike a colloidal mill, a homogenizer is better able to reduce particle size so that resulting mixtures are much more consistent and uniform. Indeed, we believe our high pressure homogenizers here at BEE International are the best option for colloidal suspensions because they utilize a proprietary combination of high pressure, shear, cavitation, turbulence and impact force to break down and blend samples without the violence and possible degradation of product that can be associated with a singular shear force. Furthermore, our machines can be customized to control the duration, intensity and dominant force used at every stage of the mixing process, making it less likely that multiple passes will be needed to get a desired result. This saves you time and money.

Finally, all homogenizers help preserve products since they facilitate a tight distribution of particles; a tighter distribution of particles means there is more stability, allowing components of a sample to stay bound for longer periods of time and, thus, engendering the improved viscosity, consistency, texture, appearance and flavor (when applicable), as well as the bioavailability, of the products being made. High pressure homogenizers like ours even kill harmful microbes that frequently jeopardize the colloid suspension’s shelf life and quality.

What is the Purpose of Homogenization?

Posted by Deb Shechter on Nov 21, 2019 1:00:00 PM

purpose of homogenizationHomogenization is the process by which a sample is broken into identical parts so that removing one portion of it does not disrupt and still accurately reflects the remaining sample’s molecular composition. In many instances, it is also used to thoroughly mix together naturally immiscible substances; when a sample is reduced to tiny, uniform pieces, it is easier for manufacturers and scientists to combine it with another sample, creating many of the products used across a wide variety of industries.

Here’s a brief overview of the purpose of homogenization:

 

To Reduce Particle Size

First and foremost, the purpose of homogenization is to reduce the size of the particles making up a sample. In simple terms, it’s a bit like taking a boulder and smashing it into gravel, except, in this case, the gravel pieces would be all the same size and shape. During homogenization, many samples can be reduced to nanometer-sized particles. This makes it easier for manufacturers to produce things like adhesives, resins, paints and creams/lotions and guarantee that they work.

 

To Lyse Cells

For the molecular and cellular biology fields, one of the most common purposes of homogenization is to breach the cell wall and/or membrane and expose the intracellular contents of cells. This is necessary when scientists need to make biological samples for further study, experimentation and research.

 

To Kill Pathogens

One the the added benefits of many homogenization techniques is the destruction of pathogens within a sample. There are several kinds of homogenizers (mechanical, high pressure and ultrasonic), each using one or more specific types of force. As a by-product of the processing method each force facilitates, many homogenizers render samples with varying levels of sterility. For instance, high pressure homogenizers can effectively kill microorganisms in food samples. Other homogenizers that produce high levels of heat (most mechanical homogenizers) can kill various pathogens, as well, but the accompanying heat frequently degrades the overall sample. Thus, it’s important to pick the right kind of homogenizing equipment if product sterility is a requisite goal.

 

To Facilitate Stable Emulsions and Dispersions

Finally, the purpose of most homogenizers is to mix substances well. Reducing the size of the particles in a substance allows it to more readily and easily combine with the particles of another substance. It also allows all of the particles to remain mixed for a longer period of time. This is especially important for products that need to be consistent in appearance, taste, texture, viscosity and/or nutritional value for the length of their shelf lives, like cosmetics, food and beverage items and pharmaceuticals.

 

The BEE International Advantage

Homogenization offers a host of benefits, and we here at BEE International believe our high pressure homogenizers are the best choice, offering advantages that would otherwise necessitate the purchase of multiple types of equipment instead of just one! Our patented Emulsifying Cell (EC) technology, along with our proprietary combination of multiple homogenizing forces, mean our homogenizers have the ability to create more stable products with longer shelf lives in shorter amounts of time with fewer passes than our competition.

The Pros and Cons of High Shear Homogenizers

Posted by Deb Shechter on Nov 4, 2019 9:22:00 AM

high shear homogenizersThere are many types of homogenizers. From basic blenders to refrigerator-sized ultrasonic equipment, different homogenizers work in and for a variety of different applications. This means choosing the right homogenizer for a specific job is a critical one. Pick the wrong homogenizer and you risk less than optimal results, some of which can cost you valuable time and money, as well as jeopardize the integrity of the products you create and/or the health of the people you serve.

 

In this blog, we take a look at high shear homogenizers. Also known as rotor-stator homogenizers, high shear mixers are one specific kind of mechanical homogenizer.
Mechanical homogenizers, as opposed to high pressure or ultrasonic ones, use a physical force to break apart a substance; in this case, a rapidly spinning rotor draws a sample into a stationary outer sheath (called a “stator”), where it is then pushed through many small openings and broken into small pieces. The rotor’s pull and the stator’s expulsion creates a significant force that consequently shears the sample apart, permitting it to be mixed more effectively in subsequent applications as needed. But while high shear mixers can be applied in a variety of ways with several associated benefits, a few potential issues do exist. Take a look at the pros and cons of the high shear homogenizer:

 

The Pros of High Shear Homogenizers

High shear homogenizers operate at a high velocity to pull, push and break apart a sample. Thus, they generate substantially smaller particles than some other kinds of homogenizers and are an especially good option for the following applications:

    1. Particle Size Reduction/Sub-Micron Homogenization

    2. Soft Tissue Homogenization

    3. Emulsification

    4. Cell Disruption and/or Isolation

    5. Organelle Extraction

 

Furthermore, high shear homogenizers often generate favorable results in a relatively short amount of time with minimal residual heat produced. Many models can be customized according to sample volume, rotor speed, processing time and energy input, with the option of using different probes to afford different effects being one of their most appealing and useful qualities.

 

The Cons of High Shear Homogenizers

On the other hand, high shear mixers are not very efficient with tough tissue samples, lysols or foams. And not all come with the probe(s) you will need for your specific task(s). Indeed, the fact that high shear homogenizers use probes at all means they are not as well-suited to processing large amounts of multiple samples at the same time since they have to be swapped out and cleaned between runs. In addition, because pieces of a sample must fit within the confines of the probe and its accompanying rotor and stator parts in order to be homogenized, some samples might need to be pre-processed, broken apart just so that they can fit into the homogenizer at all! Of course, should this circumstance arise, time-effective processing would obviously be negated. Finally, although high shear homogenizers don’t give off an excessive amount of heat, particularly temperature-sensitive samples might require that you add a cooling method to your homogenizing processes, thereby extending your processing time and costs.

 

The BEE International Difference

Picking the right homogenizer can be a tricky endeavor. If you need assistance matching your needs with the right piece of equipment, please contact a member of our team here at BEE International. We offer a variety of high-quality homogenizers featuring our proprietary and patented Emulsyfying Cell (EC) technology which, along with our combination of customizable forces (think: high shear meets sonication meets impact!) , guarantees you the most reliable and effective results no matter the application.

How Homogenization Improves Your Colloid Mixtures

Posted by Deb Shechter on Sep 16, 2019 11:10:57 AM

Colloid MixturesIf you had to write down a list of the qualities that all great products possess, what words would you choose? You’d probably start with functionality — a good product needs to serve a purpose. You’d also want it to taste or look or perform well. You might write down “value” and “sustainability.” And maybe you’d throw in “superior customer support.” While all of these characteristics accurately describe great products — no matter the industry — perhaps the most important one would be “reliability.” Great products are great only if they can be produced over and over again. For many industries (such as the food, pharmaceutical, chemical and biotech ones), great products depend on being mixed in the right way so that they appear and function the same way every time a new batch exits the manufacturing line. For colloidal suspensions, like those found in many food items and cosmetics, this means that they don’t separate or deteriorate while sitting on a shelf or in a drawer. Take a look at how you improve colloidal suspensions by using a high quality homogenizer:

 

Reduction of Particle Size

Put simply, homogenizers break apart substances. By disrupting a sample’s molecular bonds, homogenizers reduce particle size and facilitate the effective mixing of all the sample’s components. And clearly, smaller pieces make better mixtures. However, while most homogenizers utilize only one type of force to break apart and mix a sample (pressure, cavitation, turbulence, shear, or impact), our homogenizers here at BEE International are unique. Our equipment combines high pressure with all the other forces so that covalent bonds are less violently disrupted (thus, preserving other key elements), particle size is further reduced and components of a sample are more thoroughly mixed. Our proprietary homogenizing system has the added benefit of being completely customizable, allowing operators the ability to manage the duration, intensity and dominant force used at every stage of the mixing process.

 

Reduction of the Number of Passes

Furthermore, if a homogenizer does its job well, you don’t need to repeatedly pass product through its system for maximum results. Thus, fewer production passes means saved time and saved money, especially when used for large-scale manufacturing runs.

 

Preservation and Extension of Shelf Life

Another benefit of homogenization is its ability to help preserve products by creating a tighter distribution of very small particles. A tighter distribution of particles equates to more surface area on which chemical reactions can occur, with the result being better stability. Indeed, a tight distribution of particles helps mixtures stay coalesced for longer periods of time (i.e., better viscosity, consistency, texture, appearance and/or flavor), improves chemical reactions (i.e., better absorption and bioavailability) and eliminates volatile organic compounds (VOCs). When high pressure homogenization (HPH) is specifically used to mix colloidal suspensions, benefits are further compounded, as HPH acts as a preservation method, its intense pressure killing harmful microorganisms that could threaten the colloid suspension’s overall quality and length of its usefulness.
