Frequently Asked Questions About Our Team & Our Homogenizers

In what year was BEE International established?

BEE International was established in 1994 for the sole purpose of developing and bringing innovative high pressure homogenizing equipment to the pharmaceutical, chemical, biotechnology, cosmetic, and food industries.


In the above industries, what are the most common applications for your high pressure homogenizers?

The common applications are particle size reduction, fine emulsions, cell disruption, dispersions, nanoparticles, liposomes, grinding, and micro-encapsulating along with general blending and mixing. Our BEE International product line covers laboratory applications to pilot plant installations to high volume production systems.


What are the main products BEE International manufactures?

Nano DeBEE – electric laboratory systems
Micro DeBEE – air operated laboratory system
Mini DeBEE – electric/hyydraulic operated laboratory system
DeBEE 2000 – a rugged Pilot Plant system
DeBEE 2000 P    – a high volume system that scales up linearly from laboratory units

What is the specific purpose for a high pressure homogenizer in manufacturing today?

A high pressure homogenizer allows a manufacturer to breakdown droplets and particles to sizes below one micron thus effecting homogenization. The DeBEE technology, which produces the highest intensity of processing energy, generates intense forces to breakdown droplets and particles to nanometers sizes. These extraordinary results deliver small and more uniform particles after only one pass through our system.


BEE International offers an unique patented DeBEE pumping system. What are the advantages of this pumping system over conventional high pressure homogenizers?

Consistency of applied energy is critically important under high pressure. Our patented pumping system differs from the commercial triplex plunger pumps utilized by other high pressure homogenizers. The discharge characteristics of mechanical reciprocating multiplex pumps inherently vary and fluctuate with flow and pressure. BEE International has developed a proprietary pump for heavy duty, long life cycle and leak free service in a wide range of applications including sanitary conditions. Our DeBEE intensifiers are hydraulically actuated and microprocessor controlled to deliver a consistent pressure and flow to the DeBEE homogenizing cell. Particle size and particle size distribution are determined by the consistency of flow and pressure applied.


BEE International offers a patented modular DeBEE homogenizing cell. What are the advantages of this homogenizing cell over competitive fixed geometry cells?

The efficiency of energy transfer is critical as fluid flows through the homogenizing chamber. Our patented modular and configurable homogenizing cell has no wearable or moving parts and allows the user to quickly fit the homogenizing cell to meet their process requirements. Other conventional high pressure homogenizers use a fixed length orifice and fixed distance between the orifice exit and the impacted surface of the machine. There are no methods to adjust, modify or control the length and time of the flow pattern. If the provided energy is varying, the flow velocity and temperature are adversely affected. Also, processing concerns over cavitation and backpressure within the fixed interaction zone can dramatically impair the particle size reduction. To overcome these limitations, the modular and configurable DeBEE Absorption Cells (ABC) can be optimized according to operating conditions and process objectives by the combination of length, diameter and other parameters. A metering valve can be installed after the ABC to control backpressure. Therefore, the relationship between the particle size and increasing pressure is a downward straight line. By adjusting the homogenizing energy through a configured ABC, manufacturers can achieve their processing goal quickly by controlling pressure, flow cavitation, impact, shear and process duration.


Can I process dry materials and other harsh materials with your DeBEE equipment?

Our Dual Feed option allows the user to sequentially add ingredients during the in-line process to incorporate hard and abrasive materials with over 80% solids. The Dual Feed port, which is located after the nozzle on the EC, creates a natural vacuum that incorporates these materials into a high velocity jet stream while avoiding wear including non-VOC polymer and resin emulsions. Also, our Reverse Flow and Dual Jet options are utilized for applications that require with maximum shear and process duration in one pass. Lastly, extremely viscous materials can be processed with over 100,000 cP.


Do you have an Application Laboratory in Massachusetts to test some of my product?

Yes. It is common practice for customers to ship or hand-deliver product samples to BEE International for testing and analysis. Customers are required to fill out an Application Questionnaire that details and describes their application requirements, product characteristics, and processing conditions. Our laboratory testing is a cooperative process where we strive to produce unprecedented results with your product using the most optimal configuration of our patented and modular homogenizing cell.

 

Can I rent a DeBEE High Pressure Homogenizer before I make a final purchasing decision?

Yes. BEE International offers a flexible and cost effective rental program that allows the perspective user the opportunity to fully test a DeBEE homogenizer at their facility.

 

What type of technical assistance is available if I purchase a DeBEE Homogenizer?

BEE International is dedicated to provide the best service and support in the industry today. Factory trained technicians travel on-site to provide start up assistance, product training and technical support during the commissioning process. Annual maintenance agreements are available from the factory to provide a comprehensive preventative maintenance program to maintain, and inspect all system operations and functionality.
