2 Types of High Pressure Pasteurization Equipment

Posted by David Shechter on Jan 17, 2019 7:06:25 PM

two types of high pressure pasteurization equipmentIn the mid 19th century, Louis Pasteur helped France safeguard its beer and wine industries by establishing a manufacturing process that preserved and protected alcoholic products from spoilage during export. The principles of that system, eventually known as pasteurization, were based on his observations not only that microorganisms could change the molecular makeup of substances, but that they could be killed when exposed to high temperatures. Coupled with the scientific significance of French chef Nicolas Appert’s previous research on sterilization and canning techniques, thermal pasteurization quickly became the de facto approach for food manufacturers wanting to guarantee the safety and preserve the quality of their liquid and some semi-solid products.

The only problem: exposure to extreme temperatures often changes the way a food tastes, as well as its nutritional value. Believing that neither should have to be sacrificed because of safety and preservation concerns and buoyed by additional scientific advances, as well as increasing public interest in clean eating, more and more manufacturers are starting to use a high pressure processing system (HPP or pascalization) instead of heat to pasteurize their products. HPP effectively removes most pathogens and other harmful microorganisms and extends shelf life, but does not alter a food’s nutritional content, its color or its flavor. Take a look at the two most common types of high pressure pasteurization equipment: 

Water Tanks for Prepackaged Food Pasteurization

Certain prepackaged liquid and solid food items can be pasteurized using a large steel tank filled with a liquid (usually water). After the packaged food is loaded in to the tank, pumps apply pressure that changes the food’s cell structure, effectively inhibiting cell division and killing most microorganisms. According to food science research at Rutgers University, “vegetable and fruit products such as juices, salsa, dressing and guacamole; meat products such as ready-to-eat deli meats and poultry; and seafood such as shellfish and fish products” can all be processed using a high pressure pasteurization technique. The tank method is capable of processing a lot of food at one time, making it a good choice for manufacturers with high volume productions.

Homogenizers for Liquids and Semi-Solid Pasteurization

Liquids and some semi-solid products can also be pasteurized with high pressure homogenizers that push them through a series of tubes using a hydraulic pumping system that creates pressure and sterilizes them. The homogenizer then expels the product through a small opening with a drop in pressure that forces cell rupture, breaking the product apart into equally sized pieces that can be easily and uniformly mixed. Combining the pasteurization and homogenization process allows manufacturers to more efficiently manage their time, reducing their energy use and waste, and serves as a viable alternative to thermal pasteurization in the milk and juice industries especially.

Three Reasons Cannabis Product Manufacturers Choose BEE International

Posted by Deb Shechter on Dec 27, 2018 11:30:00 AM

homogenizers for cannabis1At BEE International, we understand that quality products are reliable ones. Our high pressure homogenizers produce ingredients that make cannabis product manufacturing uniform and, thus, more effective. And in an industry where news of even one bad product or experience — whether due to poor quality or poor regulatory oversight — can give those opposed to legalized cannabis consumption the fuel needed to stoke their flames of dissent, it’s paramount that licensed cannabis manufacturers take the necessary steps to ensure that the products they deliver are of the highest quality. It’s not enough simply to get a product out there.

Cannabis manufacturers must verify both the consistency and the constancy of their products even if the market doesn’t officially demand that they do so. Take a look at three reasons cannabis product manufacturers choose to partner with BEE International:

Our Homogenizers Guarantee Efficacy

Our team at BEE International has developed cannabis-specific homogenizing processes into our equipment that effectively reduce cannabis particle size. By reducing particle size, the surface area of the cannabis increases, thereby also increasing the rates of dissolution and absorption (i.e., the bioavailabilty) of the active ingredient. This facilitates many advantages, from reducing the amount of active ingredient and time needed to produce optimal effect to stabilizing and extending shelf life for storage. These benefits translate into better products and more sales for you at the end of the day. 

Our Homogenizers Reduce Costs

Our specialized inline processes mean better results in less time. Our homogenizers establish reproducible results quickly, making it more efficient for you to validate product quality. By reducing your processing time, we can help reduce your manufacturing costs! And because our homogenizers are so good at minimizing particle size and increasing bioavailability, products made with our machines need less active ingredient to ensure superior performance. Thus, you can source less active ingredient and still produce the same great effects, saving you time and money. 

Our Homogenizers Create Stable and Uniform Particles for Quality Control

Regardless of end use, a cannabis product must be reliable and capable of being exactly reproduced. Its appearance and function must meet certain standards, with potency, appearance, consistency and even smell remaining uniform across manufacturing batches and through all moments of time. Our BEEI homogenizers help verify and maintain quality control by producing similarly sized ingredient particles that are uniform in appearance, smoother in texture and easier to mix together. We guarantee “a golden clear high performance oil” for quality products that are visually appealing and functional no matter the application.

What Are Homogenizing Agents & How Do They Improve the Homogenization Process?

Posted by Deb Shechter on Dec 17, 2018 12:10:59 PM

homogenizing agentsFor most people, “homogenization” and “homogenizing agents” aren’t words that just roll off the tongue. But for us here at BEE International, talking about them comes as easily as discussing our favorite TV show or the day’s weather. So, if you’ve ever wondered what “homogenized milk” meant or how your face cream was made or why some peanut butter doesn’t have to be stirred, we’d love to share with you the facts about high pressure homogenization and homogenizing agents. Consider the following:

An Overview of the Homogenization Process

Homogenization is the process of combining two substances by breaking them into uniform pieces and mixing them together evenly. Homogenization facilitates many laboratory and manufacturing processes, such as those in the pharmaceutical, biotech, chemical, cosmetic and food industries. Not only does homogenization change the physical characteristics of materials, making it easier for scientists and manufacturers to work with raw components, it also helps ensure product quality, maintain long-term storage of materials and isolate certain particles when necessary. All of these things are necessary for superior performance among a variety of products. Homogenization makes our milk taste good and keeps our peanut butter from separating into a lump of peanut paste and a pool of oil. It keeps our lotions thick, yet spreadable, and our medicines effective.

But what if certain materials resist homogenization attempts by mechanical equipment alone? What if they need something more to help break them apart and realign their parts equally? In these cases, homogenizing agents are used.

What are Homogenizing Agents?

Homogenizing agents are resin-based mixtures which are usually added at the beginning of a homogenization cycle. When heated to certain temperatures, they turn “sticky” and help to moisten and soften the surfaces of the substances being melded together. 

How Do They Improve the Homogenization Process?

Because of their tackiness, homogenizing agents make it easier for some substances to blend and distribute their particles evenly. They also encourage filler acceptance. And by helping to shorten the time it takes to blend materials regardless of their “molecular weight, viscosity or polarity,” homogenizing agents save energy and other valuable resources.

In scientific and research settings, efficient homogenization can do more than just save time, though. It can also save lives. The right homogenizer and the right homogenizing agents can reduce the number of passes it takes to get viable results, ensuring that all steps in the testing cycle are consistent and go as smoothly and quickly as possible.

In more industrial settings, the right homogenizers and homogenizing agents ensure that applications are customized according to overall purposes, whether that be securing product stability; guaranteeing sterility; improving color, texture, taste and nutritional value; or simply maintaining cost effectiveness.

Homogenizers for Cannabis: How To Deliver More Consistent & Uniform Particle Size

Posted by David Shechter on Nov 29, 2018 11:30:00 AM

homogenizers for cannabisIf you’re looking into cannabis processing options, homogenization might seem a bit complicated at first. While there are certain elements to homogenization that are technical, homogenization is actually a pretty simple process! When it comes to particle size reduction, homogenizers work to combine two or more ingredients in a uniform manner. Since homogenization is mechanical, it doesn’t involve adding preservatives or other materials to the mixture. Thanks to pressure and other forces, particles become uniformly dispersed in the homogenization process.

When it comes to cannabis products, one of the best benefits a homogenizer can offer is how they deliver more consistent and uniform particle sizes in their dispersions. Here are the top three reasons why this should matter to you:

1. No More “Hot” and “Cold” Spots

As mentioned above, when you homogenize two or more ingredients, those particles are reduced to a small size and uniformly dispersed throughout the mixture. So without homogenization, there’s not a good way to determine where the cannabinoids are in your products. Therefore, you may have one item that is chock full of cannabinoids while the next item doesn’t have any. In fact, a recent study found 31% of cannabis products tested did not contain the amount of cannabinoids their labels claimed. That’s an unacceptable number in any industry, but can be particularly embarrassing for companies that are looking to establish themselves in the relatively new commercial cannabis industry.

2. Increased Drug Efficacy

Next, a smaller particle size will have a greater total surface area which can increase the rates of dissolution and absorption of any active ingredient. Therefore when working with cannabis, you need to ensure your products have small, uniform particle size for a greater absorption rate and there’s no better way to do this than using a homogenizer. Homogenizers can help you reach your target particle size reliably plus you can run a filter through the end product to see that all particles are the target size. Further, smaller particles can increase bioavailability by up to 75% by increasing the surface area and you can actually reduce the active ingredient required to achieve the same effect.

3. Product Appearance

While this doesn’t apply to cannabis products alone, a smaller, more uniform particle size can be beneficial for aesthetic reasons. When particles are homogenized properly, the end product can appear smoother and more homogenous. Therefore, when looking to add cannabis to lotions, food products, and other items, having a beautiful product can make all the difference when it comes to sales.

Final Thoughts

There’s a long history of businesses across all industries using homogenizers to guarantee uniformity in their product, which is something that everyone in the cannabis industry should want when creating new products. Plus, consumers want to associate with brands and products they can trust. So when you use high-pressure homogenizers in your process, you'll be keeping the promises you already make to your customers.

How to Improve RNA Isolation with Homogenization

Posted by David Shechter on Nov 15, 2018 11:30:00 AM

rna-isolationRNA isolation is, unsurprisingly, a delicate and complicated process that requires diligent execution and precise application. Indeed, even seemingly small mistakes can completely ruin an attempt to extract, isolate, and study RNA samples. With that in mind, today we’re here to explain how homogenization will help improve RNA isolation –– while also sharing a few best practices all professionals can use to boost their results when working with RNA. Check them out below:

Sample Collection and Preservation

Researchers value RNA analysis in no small part because studying RNA can help explain how genes function and are expressed. Regardless of the aim of a given experiment or project though, collecting and preserving samples in the right way is essential to generating viable results with RNA. Some tissues are notoriously difficult to extract RNA from (like bones or roots) and if samples aren’t preserved properly before homogenization, the results of a study can also be affected. As such, researchers should strive to either 1) conduct homogenization immediately following sample collection, which may not always be possible, or 2) freeze the samples using a substance like liquid nitrogen for temporary containment until homogenization can be performed. Note here that thawing frozen samples before homogenization will also affect the outcome of an experiment.

Benefits of Homogenization

The good news about utilizing homogenizers in regard to RNA extraction is that they eliminate the potential of heat production –– since high-pressure homogenizers operate so quickly. In addition, homogenizers are scalable and compatible with a wide array of sample sizes and types. Even if a samples has cell walls that are hard, or when other conditions aren’t ideal, homogenizers can still assist researchers in achieving meaningful yields. Lastly, homogenizers are key to separating samples from RNase, which as we’ll explain below, will significantly alter RNA samples and often render them unusable.

Preventing RNase Exposure

Ribonuclease or RNase, presents a problem for researchers looking to study intact RNA. RNase is an enzyme that catalyzes the degradation of RNA into smaller pieces. This is obviously something researchers want to avoid. Unfortunately, RNase is more or less everywhere, which means that it’s easy to expose a sample to it through lab equipment or on the surface of gloves. Professionals can use special cleaning solutions to ensure their equipment doesn’t spoil their experiment thanks to RNase exposure–– and should change their gloves often throughout their work. Remember also that proper storage at the end of the isolation procedure is also imperative to prevent any outside factors influencing results. RNA is generally stored at low temperatures –– either -20 Cº or -80 Cº depending on how long the storage will last. 

Final Thoughts

With the right equipment and by following guidelines and best practices to the letter, researchers can glean meaningful RNA yields under adverse conditions. At BEE International, we’re passionate about providing scalable, highly effective homogenization solutions for our business partners. We strive to offer the finest products –– and customer service –– in the industry. Don’t just take our word for it, though. Contact us today!

Why We Love High Pressure Homogenizers (And You Should, Too!)

Posted by David Shechter on Aug 30, 2018 11:30:00 AM

Love High Pressure HomogenizersIf you were asked about some of your favorite products, a high-pressure homogenizer may not make the list. However, as we’ve discussed in a previous blog, the homogenization process produces a lot of products you most likely use and consume in your daily life. That’s one of the reasons we here at BEE International love homogenizers…but there are more! Let’s take a look at some of the most popular uses of high-pressure homogenization and the benefits they offer consumers.

Particle Size Reduction

High-pressure homogenization utilizes mechanical force to break down particles or droplets in a liquid into smaller and more uniform sizes, resulting in a dispersion, which is where fine particles of one substance are scattered throughout another substance. Dispersions can be further classified into solutions, suspensions and colloids, a mixture somewhere between a solution and a suspension.

Some high-pressure homogenizers can reduce particle size to as small as a single-digit nanometer. Plus, they ensure the composition is equal throughout, and the overall molecular makeup of the sample isn’t compromised. Many high-pressure homogenizers are able to produce emulsions, dispersions and suspensions at particle sizes of 100 µm or higher, and a select few can achieve a size of down to 0.1 µm. Key benefits of particle size reduction include:

  • Increased dissolution rate.

  • Improved drug delivery.

  • Controlled rate of reaction.

  • Increased density.

  • Consistent texture and product appearance.

  • Enhanced sedimentation stability.

  • Improved mineral processing.


Important Applications

Food and Beverages

Though one of the most well-known uses of high-pressure homogenization in the food and beverage industry is for milk, it is also widely used in the manufacture of sauces, spreads, salad dressings, fruit juices and concentrates, fish and meat pâté, sweeteners, baby food, egg product, other dairy products and more. It helps companies utilize to efficiently, cost-effectively and safely produce their goods. Food homogenizers also aid in the delivery of a product with uniform texture, flavoring and taste through a scalable process that allows for a longer period of freshness than food comprised of larger particles.

Pharmaceuticals, Chemicals and Biofuels

High-pressure homogenizers are used for numerous products from the chemical and biotechnology industries and products such as pharmaceutical tablet coatings, vaccinations and creams. They can be used to create cost effective medicines, modify microorganisms, synthesize new chemicals and develop alternative biofuels.

Cosmetic Creams and Lotions

Due to its ability to provide potent particle size reduction, enriched texture and consistency and strengthened emulsion stability, high-pressure homogenization is a preferred method for improving the production of cosmetic creams, lotions and other cosmetic products. It is especially beneficial for beauty creams and moisturizing lotions because they have to have a combination of the right texture and consistency in order for the skin to be able to effectively absorb them.

RNA Extraction

 Utilizing homogenization for RNA extraction enables processing to be effectively and repetitively processed in only seconds, thereby eliminating heat production. Its force and high pressure produce consistent and uniform samples, and it can process both small and large samples. Plus, homogenizers are scalable and compatible with many sample types, including those with tough cell walls. Using a powerful chaotropic salt solution, RNA extraction purifies RNA from biological samples by quickly disrupting cells or tissue to release the nucleic acids from the cells. These released RNAs are valuable in providing details on which genes are expressed (used to make products), to what degree the genes are active, how they work to regulate each other via small, regulatory RNAs and which structural RNAs (i.e. rRNAs, mRNAs and tRNAs) are produced.

Oil Emulsification

 Due to the fact that water and oil are immiscible, powerful mixing is essential to conducting oil emulsification. Therefore, specialized machines such as high-pressure homogenizers are preferred because they not only impart high shear but also are able to reduce particle sizes much more efficiently than other blending and emulsification methods. They are used in a wide variety of research and scientific uses and by many industries that require the use of active ingredients because they reduce active ingredients to a small enough size to ensure a thorough dispersion throughout the medium produced. Additional benefits of high-pressure homogenization for oil emulsification include production of stable emulsions, improved product consistency, shelf-life, texture, color and flavor and the ability to overcome the resistance caused by two immiscible liquids.

The Ultimate Cheat Sheet for Choosing a Cell Homogenizer

Posted by David Shechter on Aug 16, 2018 11:30:00 AM

Businessman is standing in front of two direction signs.If you attended high school before laptops and tablet computers replaced books and used a landline to make phone calls, you’ve probably heard of CliffsNotes. Often used to help students figure out the intricacies of a novel that was required reading for English class, these handy pamphlets were a sort of a study guide highlighting the work’s key points.

In this blog, we’re offering you a CliffNotes version of tips for selecting a cell homogenizer that best meets your business needs. We’ll outline cell homogenization, often referred to as cell lysis, offer key factors for how best to achieve it and provide some benefits on it.

What is Cell Lysis?

Cell lysis, which takes place in biotech, pharmaceutical, food, cosmetic and chemical laboratories on a regular basis, is the rupture of the cell membrane resulting in the release of cell contents and the subsequent death of the cell. Research scientists and laboratory technicians disrupt the cell’s structure to extract organelles, proteins, DNA or mRNA. 

Cell lysis can be achieved through mechanical or chemical methods. Mechanical cell lysis techniques include high shear mixing, traditional homogenization, sonication, grinding, freeze/thaw cycles and high-pressure homogenization. Chemical cell lysis techniques include osmotic lysis and the use of detergents, chelating agents or chaotropic agents.

In order for cell lysis to be performed successfully, the following factors should be present:

  • Intracellular proteins should be accessible for extraction and solubilization.
  • The process should be flexible, as different cells require different cell lysis strategies.
  • The technique should result in a high yield in a short time.
  • The process should be relatively easy to perform.
  • Results should be consistently reproducible and scalable.

 

How Homogenization Helps

Of the methods used to achieve cell lysis, the most widely used is homogenization, which offers a multitude of benefits for production laboratories and the consumers who buy their products. It is especially useful for small volumes of cells and/or cultured ones and involves the use of shearing force on the cell. By forcing a small cell through an even smaller-sized orifice, homogenization removes the outer layer and lyses the cell. Some cell lysis products use utilize shear, and others employ sonic cavitation. However, the best choice when purchasing a homogenizer for cell lysis is one that uses shear, cavitation and impact and lets the user adjust the relative amount of each force for different applications.

The homogenizer you choose for cell lysis should be scalable to allow for customization in pressure and intensity, resulting in both cost and time efficiency for the user. It also must accommodate for multiple cell types and adjust for various sample sizes. Other factors to consider when selecting the right cell homogenizer are the force required to produce the highest yield in the least amount of time and the volume, efficiency, stability and sanitary standards compliance of the product. Advantages of using this type of homogenizer are:

  • Accessibility of intracellular proteins.
  • Built-in process flexibility.
  • Ease-of-use and low learning curve.
  • Reproducible and scalable results.
  • Various sample size processing.
  • Ability to disrupt all cell types.
  • Better results in fewer passes.

Making the Right Choice: Homogenizer Manufacturers

Posted by David Shechter on Jul 31, 2018 11:30:00 AM

choosing high pressure homogenizerShopping for certain products is easy. If you want a fast food hamburger, you have a few well-known establishments from which to choose. If you’re looking to purchase some products to stain a deck or tend to weeds in your lawn, you most likely go to your local hardware store or one of a couple bigger, nationwide home improvement stores.

Investing in a more expensive product often requires more research and comparison. Usually, you can read customer reviews online or find ratings published by consumer organizations. When purchasing a homogenizer, however, it may be harder for you to obtain the advice needed to make the right decision.

First, let’s do a little refresher on homogenization. The primary methods used for homogenization include ultrasonic, mechanical and high-pressure, and homogenizers are used across multiple industries, such as:

  • Pharmaceutical: vaccines, antibiotics, cancer treatment and medicinal creams.
  • Food and Beverage: mayonnaise, ice cream, cream liqueurs, salad dressings, dairy products and more.
  • Biotech: creation of cost-effective medicines, modification of microorganisms, synthesization of chemicals and development of alternative biofuels.

Based on these details, the first step in finding a homogenizer manufacturer in asking yourself the following questions:

  1. Why do I need one?
  2. What differentiates one homogenizer from similar ones on the market?
  3. Does my product require a specific particle size?
  4. Which accessories are recommended and/or required for optimal performance?
  5. What motor power does my product require?
  6. Do I have a desired tube capacity and/or mixing speed?

By understanding the available options and what can best help you accomplish your specific homogenization goals, you are better equipped to select a manufacturer to meet your specific needs. It’s important to choose a manufacturer who will work with you to customize a homogenizer that delivers the best possible results. Some companies are able to customize the forces in their homogenizers to suit your application. Some even produce separate homogenizers for each phase of drug development.

Consistency is essential in homogenization, so employing the services of a manufacturer who aids you in reproducing reliable results is imperative. They should offer a homogenizer that is easy to scale and enables the product developer to quickly apply a wide variety of mixing techniques to a formulation. The manufacturer should have a reputation for reliability, offer customer referrals and provide you with at least once demonstration of their product(s).

Once you’ve decided on a manufacturer from which to purchase your homogenizer, factors to consider when choosing a brand and model include:

  • Sample types.
  • Maximum operating pressure. 
  • Mixing speed.
  • Processing setup. 
  • Processing range.

Six Tips for Ensuring Safety When Using Your High-Pressure Homogenizer

Posted by Deb Shechter on Jul 12, 2018 10:30:00 AM

high pressure homogenizerSafety first. It’s a phrase you hear fairly often, and although it may seem unnecessary to repeat, it’s especially important when working with large machines or those with many parts. When not used correctly, these machines can not only fail to produce an optimal product but also cause injury. 

Homogenizers fit into this category, so we’re offering the following tips on how to use yours and the samples it produces both safely and effectively:

1. Wear the appropriate protective equipment.

As with any such machine, these elements are designed to keep the user safe from moving parts and any hazardous chemicals. Whether it’s gloves, eye goggles or even ear plugs, investing in these accessories can keep you from damaging any part of your body, especially your eyes and ears. Some high-pressure homogenizers can reach 85 dBA and potentially cause ear damage.

2. Follow operating instructions and regulations.

There are safety laws and guidelines produced by unions and the government for a reason. These rules are designed to keep you safe while ensuring the machine you’re using is working as it was designed to do. To make sure you always have your high-pressure homogenizer’s instruction manual when you need it, keep it with the machine, and store a copy with your other important documents.

3. Use only the parts that came with your high-pressure homogenizer.

The parts that make up your high-pressure homogenizer are designed to work together and should not be substituted with another accessory or attachment. Failure to follow this rule may cause your product to work at a decreased level or even break, often voiding your warranty.

4. Avoid contact with the rotating shaft and homogenizing head.

Contact with either of these sharp parts can cause injury, so make sure you always switch the machine off before cleaning it or changing screens. Be especially careful when handling your high-pressure homogenizer after it has been contaminated with dangerous samples.

5. Let only trained operators handle your high-pressure homogenizer.

When installing or operating your homogenizer or simply doing maintenance on it, have only those trained to do so perform the task. Improper handling can cause both machine malfunction and minor injury to the handler.

6. Follow common electrical precautions.

Again, these rules are in place for a reason, and failing to follow such rules may result in electrocution or shock.

Homogenizers and the Forces That Drive Them

Posted by Deb Shechter on Jun 25, 2018 11:30:00 AM

forceForce sounds like a very scientific term, but it basically consists of pushing, pulling and gravity. Pushes and pulls set things in motion, while gravity pulls down everything on earth. The six kinds of forces that act on objects when they come into contact with one another are: normal, applied, frictional, tension, spring and resisting.

In high-pressure homogenization, mechanical forces enhance the effectiveness of utilizing extremely high operating pressures. The combination of four main forces – cavitation, high shear, impact and turbulence – are used with high pressure to achieve particle size reduction, cell lysis and/or effective emulsification.

Cavitation

Cavitation occurs when a high amount of pressure is exerted on a liquid sample. Pressure enables the liquid to achieve high kinetic energy, thereby increasing velocity. Also sometimes described as the formation of liquid-free spaces within a liquid, cavitation is especially useful for particle reduction and can be intensified or reduced by adjusting the size of a high-pressure homogenizer’s nozzle.

Although homogenization can be accomplished without cavitation, it increases the efficiency of the process. In the food industry, cavitation in homogenization breaks up large fat globules to create a stable emulsion for increased shelf life and improve taste and texture.

High Shear

High-pressure homogenizers work through shear force, which can be created when a tangential force is applied to a sample. Homogenization using high shear allows for even further reduction of particle size by mixing two normally immiscible phases, such as with water-in-oil (w/o) or oil-in-water (o/w) emulsions.

Many high shear mixers are used to reduce particle size, but high-pressure homogenizers are able to attain even higher shear rates. This is especially important when a dispersion is required.

Impact

The force of impact works in homogenization to reduce the particle size of solids into liquids and achieve lysis of difficult-to-disrupt cells and other materials though the use of grinding beads. Dounce and Potter-Elvehjem homogenizers use only the force of impact to lyse cells, while the French press counterpart adds in high shear. The ability of high-pressure homogenizers to combine multiple forces offers manufacturers better yield in fewer passes and a lower time requirement. Along with other mechanical forces, impact can be fine-tuned to accommodate a specific sample.

Turbulence

In the overall homogenization process, turbulent premixing is the stage designed to prepare a sample by mechanically loosening bonds. By high-pressure machines like stirrers and agitators putting a sample through turbulent premixing, the homogenization process is easier and more time-efficient.

Another influence in homogenization is process intensity; higher intensity is used to obtain smaller particle sizes in fewer passes. Though not all homogenizers are equipped with adjustable process intensities, those from BEE International allow for increased or reduced process intensity with only the turn of a dial.

BEE International: The Driving Force Behind the Best High-Pressure Homogenizers

Unlike other technologies which apply one mechanical force to mix a product, BEE technology utilizes all available mechanical forces to achieve optimum results. We synergistically combine and fine-tune these forces to produce the best possible product for you and let you produce a tight distribution of small, uniform particles every time.
