In the food-processing industry, they provide a perfect solution for reconstituting powdered milk, making syrups, preparing brines, etc.
They can also be a solution to preparing solid-liquid mixtures in the pharmaceutical, cosmetics and chemical industries.

The blender basically consists of a casing and a centrifugal pump impeller which are mounted vertically. The suction side has a double-wall pipe that keeps the inlet of solids separate from that of liquids, thus avoiding the formation of lumps before the material enters the casing. 
The liquid enters the mixing chamber at a high speed, thereby creating a vacuum at the center of the impeller, which causes the suction of the solids. The fall of the solids can be regulated by means of a valve situated at the bottom of the hopper.
