FLUIDIZED BED DRYING AND STERILIZING APPARATUS USING DEPRESSURIZED SUPERHEATED STEAM

摘要

PROBLEM TO BE SOLVED: To provide a fluidized bed drying and sterilizing apparatus using depressurized superheated steam having high drying capacity, eliminating the need of a large-sized facility, capable of drying field crops, foods, chemical materials, and food residues of industrial wastes at low temperatures, and capable of sterilizing satisfactorily.;SOLUTION: This fluidized bed drying and sterilizing apparatus comprises a vacuum pump D depressurizing the inside of the apparatus, a steam tank A generating steam in a state depressurized by the operation of the vacuum pump D, a heating heater B heating the depressurized steam to generate depressurized superheated steam, and a fluidized bed drying apparatus body C drying dried materials. The depressurized superheated steam is led into the fluidized bed drying device body C to dry the dried materials (a) by the depressurized superheated steam in a fluidized state.;COPYRIGHT: (C)2006,JPO&NCIPI
