Abstract

A plurality of stacked trays 2 are accommodated within a rotary housing 3 rotatably supported in a sterilization vessel 1 (FIG. 7a). A medium support port 42a is sealingly engaged with an inlet port 25. Then, a flow of hot water is supplied to the inlet port 25. Thus, a spray hot water is ejected from spray nozzle 23 for heat sterilizing products on the trays 2. Thereafter, a spray of cooling water is ejected from the spray nozzle 23 for cooling the products. The rotary housing 3 is rotated to a position in which inclination of the trays 2 exceeds 90 degrees. Then, the rotary housing 3 is counter-rotated to a position in which the trays 2 are inclined at a vertical orientation (FIG. 7b). A hot gas supply port 37a is sealingly engaged with the inlet port 25 so as to supply a flow of hot air into the inlet port 25, whereby the products may be dried.
