Explaining Silverson In-Line Mixer Pumping Capacity

The latest animation to be released in Silverson Machines ‘Silverson Mixing Science' series explains the pumping capacity of high shear In-Line mixers.

When mixing continuously in larger batches, In-Line mixing is often the method chosen by manufacturers to get the best results; it also offers greater energy efficiency over in-tank mixers as the mixer’s effort is concentrated on a small volume in the mixing chamber rather than having to circulate the entire volume in the tank.

But, although Silverson In-Line mixers are self-pumping, some people think that they will need a very powerful machine to recirculate the product back to the top of a large tank. The new animation debunks this by explaining how a Silverson In-Line mixer can recirculate product in a large tank without the need for pumps or additional power.

High shear rotor/stator In-Line mixers have the ability to form stable emulsions, de-agglomerate, reduce particle and droplet sizes and blend powdered and liquid ingredients.

These self-pumping mixers consist of a high-speed rotor turning with close clearance inside a fixed stator. This workhead is impossible to bypass so all material is subjected to high shear as it passes through the workhead.

They have a higher flow rate than some of the other options discussed with a standard Silverson In-Line mixer able to process up to 200,000 litres per hour. This rate may be slower for more viscous products, but Silverson also offers a High Viscosity In-Line mixer with a special ‘pumping' rotor for processing high viscosities.

The HV In-Line does not require an additional feed pump and can process products such as Mayonnaise and gels.
