Looking to Eliminate Aeration from Your Mixing Process?

Aeration during the mixing process can cause problems further along the production line, where containers are filled by weight rather than volume and it can also reduce the shelf life of the end product. For the manufacture of products such as shampoos and detergents, aeration during the mixing process must be avoided since their tendency to foam can cause major problems.

But how can manufacturers reduce or even eliminate aeration whilst the product is being mixed? Unlike conventional mixing equipment, which can create a large vortex in the tank, with High Shear rotor/stator mixers such as a Silverson, the circulatory pattern of mixing happens below the surface, keeping aeration and foaming to a minimum.

Silverson In-Line mixers offer completely aeration-free operation. The mixer, pipework and vessel form a closed system, and the flooded suction provided by the self-pumping mixer cannot introduce air into the mix or the end product. These are widely used for applications such as diluting SLES or forming emulsions, with the two liquid streams being fed into the machine via a manifold so that they mix on contact in the high shear zone inside the workhead.

Silverson experts understand the mixing challenges you face in the cosmetics industry, such as reducing production times, producing stable emulsions, dissolving powders, disintegrating solids, blending liquids of different viscosities, dispersing and hydrating gums, thickeners and stabilisers, and diluting high active surfactants. We will work with you to make sure you get the right mixer for your specific needs. Silverson has the flexibility to custom design and build machines to meet your exact specifications.

For applications such as shampoos and conditioners, lotions and creams, nail varnish and liquid soaps, Silverson has a mixing solution for you.
