Homogenisation requires the ingredients to be processed until a uniform globule or particle size. For most products, including creams, ointments, sauces, flavouring emulsions and pharmaceutical suspensions, this requires a globule or droplet size in the range of 2 – 5 microns.
This can be achieved using a Silverson Mixer Homogeniser. The precision-machined Silverson workhead generates exceptionally high shear rates in a three stage mixing/homogenising process; The high speed rotor draws materials into the workhead where they are intensely mixed. Centrifugal force then drives the materials to the periphery of the workhead and subjects them to mechanical shear in the precision gap between the rotor and stator. This is followed by intense hydraulic shear, as the product is forced through the stator screen at high velocity and circulated back into the mix. Fresh material is continually drawn into the workhead, progressively reducing globule or particle size and quickly resulting in a homogeneous, uniform product.
Silverson offers a range of in-tank and In-Line mixers for this process. You can test a Silverson mixer at your own facility – the initial period is free. Contact Silverson today.
