What is high shear homogenizer?
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: Particle Size Reduction/Sub-Micron Homogenization.
What is Silverson homogenizer?
Silverson Mixer Homogenizers are fast and efficient and are capable of producing a fine droplet or particle size, typically in the range of 2 ā 5 microns. This degree of homogenization is suitable for the vast majority of products, such as creams and ointments, lotions, sauces and flavor emulsions.
What is Silverson high shear mixer?
Silverson High Shear In-Line mixers are supremely efficient and rapid in operation and are capable of reducing mixing times by up to 90%. The action of any Silverson In-Line mixer can be modified with the use of rapidly interchangeable workheads.
Which mixer works with high shear stress?
High shear mixers, also known as high shear reactors (HSRs), rotor-stator mixers, and high shear homogenizers, are used to emulsify, homogenize, disperse, grind and/or dissolve immiscible mixtures with components of the same or different phases.
What is considered high shear?
Abnormally high shear rates in the range of 5000ā20,000 sā1 are typical of stenosed (constricted or narrowed) regions of the arteries.
What are high shear mixers used for?
A high-shear mixer can be used to create emulsions, suspensions, lyosols (gas dispersed in liquid), and granular products. It is used in the adhesives, chemical, cosmetic, food, pharmaceutical, and plastics industries for emulsification, homogenization, particle size reduction, and dispersion.
What is principle of Silverson mixer?
Silverson mixer emulsifiers use high-speed rotors to create turbulence and intense shearing forces. Through the turbulence created by the perforated metal sheets, the liquid passes through fine interstices. Suction from the bottom of the head causes material to circulate through the head.
What is Silverson mixer emulsifier?
What does a high shear mixer do?
Why use a high shear mixer?
A high shear/high-speed rotor-stator mixer is more advanced, and significantly more capable, than a traditional rotor-stator mixer. These are the machines that provide more bang for the buck when a traditional rotor stator is not quite up to the task, but a high-pressure homogenizer is not necessarily required.
What is the difference between high shear and low shear?
High shear, or very forceful, mixing processes uses high-speed impellers, and low shear mixing processes use flow, turbulence, and rotational force to combined miscible goods.
How does a high shear mixer work?
Fluid undergoes shear when one area of fluid travels with a different velocity relative to an adjacent area. A high-shear mixer uses a rotating impeller or high-speed rotor, or a series of such impellers or inline rotors, usually powered by an electric motor, to “work” the fluid, creating flow and shear.
What is the principal of Silverson mixer homogeniser?
The principle of the Silverson mixer is based upon shearing force. It produces intense shearing forces and turbulence by the use of high-speed rotors. Circulation of material takes place through the head by the suction produced in the inlet at the bottom of the head.
At what speeds shear mixers can works?
8. At what speeds shear mixers can works? Clarification: The rotor works at a speed of the order of 3000 to 15000 r.p.m. and the clearance can be adjusted between 50 and 500 micrometers.
