Working of Silverson mixer

1. Silverson Mixer Homogenizers

2. Mixing: Mixing is randomization of dissimilar particles within the system. Mixing may also be defined as the process in which two or more than two components in a separate or roughly mixed condition are treated in such a way so that each particle of any one ingredient lies as nearly as possible to the adjacent particles of other ingredients or components.

3. Silverson Mixer Homogenizers: Silverson's mixer has Silverson workhead - the heart of machine which provided high shear mixing. 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 .

4. The advantages of Silverson’s high shear rotor/stator mixer over simple conventional stirrers or agitators stem from the multistage mixing/shearing action as materials are drawn through the specially designed Silverson workhead - the heart of every machine . Silverson mixer Homogenizers are widely used in food, pharmaceuticals and chemical Industries. Principle Silverson Mixer Homogenizers works on the principle of high shear mixing.

5. Silverson mixer Homogenizers are high shear mixers and are capable of reducing mixing times up to 90% when compared to conventional methods. The specially designed workhead allow mixer to disintegrate, dissolve and homogenize at the same time. In conventional mixers ingredients are quickly begin to move as a single body and dissolve by shear mixing. This can take more time while the same thing can be achieve in matter of seconds by Silverson mixer Homogenizers.

6. Construction and Working: Mixing Stages: The 2 stage mixing cycle accelerates the dissolving process as follows: Stage1 The vessel is charged with liquid and the mixer is started. The high speed rotation of the rotor blades creates a powerful suction which draws the liquid and powdered ingredients into the workhead where they are rapidly mixed.

7. The high-speed rotation of the rotor blades within the workhead exerts a powerful suction, drawing liquid and solid materials upwards from the bottom of the vessel and into the center of the workhead . Centrifugal force then drives materials towards the periphery of the workhead where they are subjected to a milling action in between the ends of the rotor blades and the inner wall of the stator.

8. Stage2 The particles are reduced in the gap between the rotors and stator wall. The product is forced out of the stator and projected radially back into the body of the mix as fresh ingredients are drawn into the workhead .

9. The materials expelled from the head are projected radially at high speed towards the sides of the mixing vessel. At the same time, fresh material is continually drawn into the workhead maintaining the mixing cycle. The effect of the horizontal.
