Homogenising

High pressure homogenisers are used in a variety of applications, in the food, chemical and pharmaceutical industries, particularly in the preparation of emulsions. While they provide exceptional high shear rates and ultra-fine globule size, these devices have high capital, operating and maintenance costs.

Homogenisation of many products can be carried out using a Silverson high shear mixer. In many cases the fine globule or particle size obtained – typically in the range of 0.5 to 5 microns – is sufficient for process requirements, eliminating the need for further processing. However, where a high pressure homogeniser must be used, passing the product through a Silverson In-Line mixer first will dramatically improve throughput, process efficiency and reduce operating costs. This is because high pressure homogenisers work better when fed with a premix of uniform and fine globule or particle size, allowing the product to pass through the homogeniser at a much faster rate, normally in a single pass.

Silverson offers multistage rotor/stator configurations and special ultra-fine stator screens which provide intense high shear, further reducing homogenisation times by reducing the number of recirculation passes required.
