Abstract

The original construction of a laboratory drying plant for dehydration of raw material under soft conditions has been designed. The opportunity to intensify food raw material thermal dehydration applying a reversed scheme of using argon as a drying agent with its regeneration and return into the cycle of consequent processing has been determined. A continuous method of drying of subtropical raw material, roots and fish has been suggested based on fulfilled theoretical researches. The experimental research of apple, persimmon, salmon and celery slices drying kinetics has been fulfilled in the drying plant designed by the authors. Kinetic parameters of dehydration of raw materials of plant and animal origin have been determined. The technical result provided by the updated pilot plant is the increase of the finished product quality and the reduction of expenditure of electric energy used for agricultural raw material drying.
