KINETICS OF DEHYDRATION OF VEGETABLE MATERIALS IN A DENSE BED WITH CYCLIC MICROWAVE-CONVECTIVE ENERGY SUPPLY

Certain results are presented of experimental investigation and numerical modeling of the kinetics and heat and moisture transfer in a blown dense bed of vegetable materials with convective and cyclic microwave-convective energy supply. The kinetic dependences of the dehydration of vegetable materials are analyzed and the possibility of reducing the duration of the process is shown with the example of raw-potato and celery-root particles. A comparison is made of the calculated and experimental kinetic dependences which points to their satisfactory agreement and to the adequacy of the model.
