るのみならず、常温で投入した物品の凍結速度を制御す
ることなどは不可能に近い。However, if items at room temperature are placed outside in this state, the temperature inside the storage tank will temporarily rise, which not only has a negative effect on the stored items, but also makes it impossible to control the freezing rate of items placed at room temperature. Close to possible.
投入する物品によってはその凍結温度が品質に及ぼす影
響は大である。The freezing temperature has a great effect on the quality of the products depending on the product.
本発明の目的は凍結保存槽と、急速凍結槽をあわせ持つ
装置を提供することにある。An object of the present invention is to provide an apparatus having both a cryopreservation tank and a quick freezing tank.
本発明の特徴とするところは凍結保存槽の他に急速凍結
槽を設け、これを冷凍機によシ常温からプログラム冷却
運転を行わせたり、さらに急速凍結が必要な場合は液化
炭酸ガスを噴射したりして凍結速度を制御できるように
して、凍結保存槽内の温度に影響を与えないようにする
点にらる。The feature of the present invention is that a quick freezing tank is provided in addition to the cryopreservation tank, and this is used by a refrigerator to perform programmed cooling operation from room temperature, and when rapid freezing is required, liquefied carbon dioxide gas is injected. The idea is to be able to control the freezing rate by doing things like this, so as not to affect the temperature inside the cryopreservation tank.

る。Cooling pipe 12.1 of cryopreservation tank 1 and quick freezing tank 5
5 is a compressor condenser 10, a capillary tube 11.1
This is an evaporator for a refrigeration cycle consisting of four parts. 2 is the lid of the cryopreservation tank 1; 5 is the machine room; the compressor 9, the condenser 10,
A liquid electromagnetic valve 16, capillary tubes 11, 14, etc. are housed. 4 houses equipment for controlling the operation of the compressor 9, the liquid electromagnetic valve 13, the blower for the condenser 10, and the like. 6 is a lid of the quick freezing tank 5. 7 is a heat insulating material forming the cryopreservation tank 1, and 8 is a heat insulating material forming the quick freezing tank 5. 16 is a liquefied carbon dioxide gas cylinder, and 17 is a solenoid valve, which connects the liquefied carbon dioxide gas cylinder 16 through piping 18.
, connected to the evaporator 15. Normally, the internal temperature of the cryopreservation tank 1 is controlled by turning the compressor 9 on and off.

保存し、温度管理を行う。When storing an entire article at room temperature by freezing, the article is first placed in the quick freezing tank 5, and the freezing speed is controlled while fully controlling the flow of the refrigerant by opening and closing the liquid solenoid valve 13. In this case, a liquefied carbon dioxide gas cylinder 16 (liquefied nitrogen gas may be used) may be connected as an auxiliary means for increasing the freezing speed, and the freezing speed may be controlled by opening and closing a solenoid valve 17. Alternatively, there is a method in which a prine such as methanol is placed in the quick-freezing tank 5 for cooling, and the article is immersed in the prine to quickly freeze the product. The frozen articles are transferred into a cryopreservation tank 1 and stored frozen, and the temperature is controlled.
