Pasteurizer
First Claim
1. In a pasteurizer having a countercurrent means which flows reversely a rinse water sprayed in a cooling vessel of end side existing in the most downstream side to a cooling vessel of upstream side utilizing overflow function or circulating-spraying and cooling function while work containers such as cans and bins and so forth filled with product liquid, after high-temperature sterilization, are carried in one after another to plural cooling vessels disposed in serial array, a pasteurizer for cooling work containers comprising:
- an adsorption freezing machine between a high temperature cooling vessel disposed at carry-in side of work containers and a low temperature cooling vessel disposed at downstream side wherein a cooling liquid obtained by supplying a stored liquid of the high temperature cooling vessel of carry-in side as a heating source liquid to the adsorption freezing machine disposed at the downstream side; and
a means for halting or flowing liquid to stop supplying the heating source liquid in case of no-load state.

Abstract
An energy and water saving pasteuriser capable of maintaining a stable temperature distribution pattern even when transfer work are interrupted during the operation, or a tunnel type refrigerator (10) allowing hot work such as bottles and cans filled with the products sterilized at a high temperature of generally 75° C. to allow temperature of generally 25° C., wherein plural cooling vessels (11a, 12a, 12b, 12c, 12d, 13a, 13b) are disposed in a row from the upstream side to the downstream side so as to form a first cooling region (11), an intermediate cooling region (12), and a final cooling region (13), an adsorption freezing machine (19) is installed between the first cooling region (11) and final cooling region (13), and a cooling tower (20) is installed in the intermediate cooling region (12).

5. In a pasteurizer which sterilizes a liquid filled in work containers with heat energy having a preheating region, heating region, sterilizing region, precooling region and cooling region, which form heat-exchanging function by circulating-spraying between storage trays and spraying parts spraying liquid to work containers such as cans, bins and so forth along a transporting path from the upstream to the downstream, a pasteurizer for sterilization comprising:
-
a line for supplying a cold heat or heat energy which forms and holds each temperature region in the each storage tray;
a cross-linked circulating path for spraying liquid which is formed between a circulating spray liquid of the preheating region sprayed in the precooling region and a circulating spray liquid of the precooling region sprayed in the preheating region;
a line for supplying a low temperature which makes a low temperature circulating spray by supplying a cold heat energy to a heat-exchanging chamber of the cooling region; and
a line for replenishing a stored liquid replenishing a stored liquid to an upstream side storage tray by cooling and storing overflow liquid of each storage tray. - View Dependent Claims (6, 7, 8)
