Title:
QUICK REFRIGERATION APPARATUS AND QUICK REFRIGERATING METHOD
Document Type and Number:
WIPO Patent Application WO/2006/114813
Kind Code:
A1
Abstract:
[PROBLEMS] To provide a quick refrigeration apparatus and a quick refrigerating method for refrigerating an object to be preserved while maintaining the freshness and high quality of the object over a long term by suppressing subtle reactions of the object and the gas in the storage thereby preventing deformation/degeneration of the object, and applicable to long term preservation of a tissue of an organism. [MEANS FOR SOLVING PROBLEMS] The quick refrigeration apparatus comprises a refrigerated storage (11) provided with a door for placing and taking out an object (3) to be preserved, a refrigerating machine (17) capable of lowering the temperature in the storage below about -30°C, a pressure regulator (60) for regulating the gas pressure in the storage, and a means (31) for supplying cooling air to the object contained in the storage at a wind velocity of 1-5 m/sec. The pressure regulator (60) comprises an operation control means (68) which detects the temperature in the storage and operates a pressure reducing means (62) to reduce the pressure in the storage to the atmospheric pressure or below when the temperature in the storage exceeds a predetermined level, stops the operation of the pressure reducing means (62) when the temperature in the storage exceeds the predetermined level, and operates a pressurizing means (61) to increase the pressure in the storage above the atmospheric pressure.
