Silverson emulsifiers mix or homogenize coarse particles in the emulsion and suspension, reducing them to fine particles. Its capacity ranges from 1 ml to 12 lt, and its ability to mix in-line with flow rates is up to 20 lt/min. Principle Silverson emulsifier works on the principle of shearing forces and turbulence produced by the…
Turbines are mechanical devices that mix different fluids with blades and impellers. Turbines are used for mixing high viscosity liquids because of the greater shear forces produced by them than the propellers. They are used especially for the preparation of emulsion. For preventing vortex formation, baffles are often used. Construction ¨ Turbines consist of a…
A Double cone blender is a competent and versatile machine used for uniform blending of granules and dry powders. It is made up of stainless steel. It is available in various working capacities ranging from 5 – 500 liters. Principle A double-cone blender produces a homogeneous solid-solid mixture. This equipment involves axial mixing as the…
Mixing is among the most important unit operation processes in many industries. It involves the mixing of solids, liquids, or gases having two or more than two components. Mixing is the process where two or more ingredients are treated so that every particle of any one ingredient lies as near as possible to the particle…
