Flashmix Powder/Liquid Mixers

The Silverson Flashmix takes a revolutionary approach to powder/liquid mixing. Unlike many powder/liquid mixers, which use vacuum to pull in powders, the Flashmix literally forces powder into the liquid stream. This not only allows it to disperse and hydrate large volumes of powders, it means it can be used at higher temperatures and with higher viscosity mixes - offering the advantages of high shear mixing to a wide range of applications that were previously not possible. 


  • Rapid powder incorporation rates of up to 500 lbs/min
  • Consistently agglomerate-free product, ensuring uniformity every time
  • Suitable for high-temperature operations with exceptional performance
  • Ideal for higher concentrations of gums and thickeners
  • Minimized aeration for optimal results
  • Sanitary design based on a 3-A Certified and EHEDG Certifiable sanitary mixer
  • Modular construction offers versatility for various applications and batch sizes
  • Low power requirement without the need for additional pumps
  • Ergonomic, low-level design for user convenience
  • Simple: the Flashmix is easy to install, easy to operate, and easy to clean

How It Works

The Silverson Flashmix offers a unique method of incorporating powders into liquids, producing an agglomerate-free and homogeneous product.

Stage 1

The specially modified Silverson In-Line mixer recirculates liquid from the process vessel through the Flashmix at high velocity.

Stage 2

The powder feed valve is opened, and the high pumping action of the In-Line mixer forces the powder into the liquid stream.

Stage 3

The powder and liquid components are introduced straight into the high shear zone of the mixer, and are instantaneously combined as they are subjected to intense mechanical and hydraulic shear. The resultant mix is passed back to the vessel by the self pumping Flashmix.

Mixer Options


A comprehensive range of workheads and screens is available for all Silverson high shear mixers. These easily interchangeable workheads offer great versatility by allowing any machine to be adapted to perform a wide range of mixing operations including emulsifying, homogenizing, disintegrating, dissolving, dispersing, blending, particle size reduction and de-agglomerating. Changing from one head or screen to another is quick and simple.
