What is Silverson mixer emulsifier?
Silverson mixer emulsifier produces intense shearing force and turbulence by the use of high-speed rotors. This turbulence causes the liquids to pass through fine interstices formed by closely placed perforated metal sheets.
Why is shear mixer high?
High-shear mixers are sophisticated machines capable of dispersing powdered solids into high viscosity liquids — emulsifying otherwise immiscible liquids, mixing disparate substances (e.g., powders into liquids; liquids into other liquids), significantly and evenly size-reducing particles, achieving uniform blending …
Which mechanism of mixing in Silverson mixer is?
| Q. | Mechanism of mixing in silverson mixer is: |
|---|---|
| B. | laminar |
| C. | Random |
| D. | Turbulent |
| Answer» d. Turbulent |
What is high shear granulation?
High shear granulation is a shaping process for granulation that has been enhanced for application in the pharmaceutical industry. A binder liquid is fed to the powder particles in a closed container with blending tools and a chopper. Dense granules are formed through the liquid and solid bridges that result.
Which part in Silverson mixer homogenizer is used for emulsification?
shear rotor/stator
The more shear energy introduced into the mix, the smaller the suspended droplets will become, creating a fine stable emulsion. The high shear rotor/stator design of the Silverson mixer is ideally suited to this application and can easily achieve emulsions with a droplet size of 2 to 5 microns.
How does a high shear mixer work?
A high shear mixer uses a rotor, rotating at high speeds, to direct material outwards towards a stationary stator and thus shear the material. Variable rotor speeds provide the ability to uniquely tailor the amount of shear energy for each application.
Which mixer is a first high-shear powder blender mixer?
Option (b) is correct. Littleford lodige mixer is also known as a granulator.
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.
What is high shear mixer granulator?
A high-shear granulator consists of a cylindrical or conical mixing bowl, a three-bladed impeller, a chopper, an auxiliary chopper, a motor to drive the blades and a discharge pot. Binder addition or addition of granulating liquid. Wetting of powder and nucleation. Growth of granules and densification of the powder.
What is Silverson mixer 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 – 5 microns. This degree of homogenization is suitable for the vast majority of products, such as creams and ointments, lotions, sauces and flavor emulsions.
