Abstract
PURPOSE: To suppress the proliferation of bacteria in the circulating thawing liquid or exterminate the bacteria, and to improve the preservability of the thawed food, by branching a part of the circulating thawing liquid during the thawing process, sterilizing the branched liquid completely, returning the sterilized liquid to the circulating thawing liquid, and cooling the liquid to the preset thawing temperature.
CONSTITUTION: Frozen foods 4 such as frozen fishes the frozen meat are releasably placed on a tray 3 in a thawing chamber 1. In case of thawing the foods frozen at -10W-30°C, thawing liquid controlled at about 10W30°C is forcibly circulated through the chamber 1. The thawing liquid cooled by the thawing process is pumped with a pump 7, and pieces of meat, etc. in the liquid are removed with a filter 8. A part of the circulating thawing liquid is branched at a branching pipe 12 to a sterilizer 13, where it is heated at 120W130°C. The sterilized liquid is returned to the circulating liquid through a branch 12', and cooled with a cooler 10 to the preset thawing temperature. The temperature-controlled liquid is introduced into the thawing chamber 1.
