Abstract
Dairy industry liquid products have short terms of validity. Therefore, it has become very popular to produce dairy products in the form of powder. This powder is obtained by a two-step spray drying method. At an initial stage, the raw material is preliminarily dried in a spray dryer (to get 10% moisture). At the following stage, it is thoroughly dried in a vibrating fluidized bed dryer (3-4% moisture). Fluidization is a process, in which dry grains of solid contact fluid to generate a fluidized bed that behaves similarly to boiling liquid. Owing to this process, powder of improved physicochemical properties is formed. The aim of our study was to describe the construction and working principles of a whey vibrating fluidized bed dryer.
