ShareSummary
AN EXPERIMENTAL STUDY OF A FLUIDIZED-BED FREEZE-DRIER SHOWED IT TO BE FEASIBLE. THE DRYING KINETICS WERE DETERMINED IN THE CASE OF POTATO SLICES. THIS PROCESS IS LONGER THAN VACUUM FREEZE-DRYING, BUT ENERGY SAVINGS ARE ABOUT 35 %. A MODEL WAS SET UP TO TEST HEAT AND MASS TRANSFERS. THIS FREEZE-DRYING PROCESS IS MAINLY APPLIED TO SMALL PRODUCTS, AT A TEMPERATURE APPROXIMATING THE MELTING POINT. (Bibliogr. int. CDIUPA, FR., 91-273567 AND 273568.
