FUNDAMENTALS OF CONTACT-SORPTION DEHYDRATION OF LABILE MATERIALS

The present study deals with the fundamentals of the contact-sorption mass transfer theory. The criteria used to determhe the rate of a process and the quality indic- es of a product with contact-sorption dehydration of the material are formulated. The methods to calculate a re-quired amount of sorbent are presented, and an estimate of comparative moisture capacity of sorbents is proposed. Examples of the implementation of sorbents in sublimation and vacuum drying, in fluidized bed drying, and in spray- drying are illustrated.
