The freezing liquid used when freezing items by immersing them in freezing liquid at -30 degrees or below contains calcium chloride, methanol, methylene chloride, ethylene glycol, trichloroethylene, and freon.
11, etc., but ethylene glycol or Freon 11 is preferable from the viewpoint of danger and corrosiveness of tanks containing these refrigeration liquids.

しかし、エチレングリコールは沸点が105℃位

ために熱交換効率が低下するという欠点がある。
これに反し、フレオン11は、沸点が23.7℃と低い

下を来たすことがないという利点がある。
However, ethylene glycol has a boiling point of around 105℃, and although it has the advantage of hardly evaporating at room temperature, it becomes very viscous at temperatures below -30℃.
Therefore, there is a drawback that heat exchange efficiency decreases.
On the other hand, Freon 11 has a low boiling point of 23.7°C, but has the advantage that it has a small viscosity even below -30°C and does not cause a decrease in heat exchange efficiency.

The present invention takes advantage of the advantages and disadvantages of ethylene glycol and Freon 11, and also focuses on the fact that ethylene glycol has a specific gravity of 1.093, which is lower than Freon 11's specific gravity of 1.608, making it difficult to evaporate and effective at low temperatures. We are now able to provide a method for freezing food.

Therefore, in the freezing method of the present invention, the container 4 containing the object to be frozen is transferred to the Freon brine 3 in the tank 1.
The object to be frozen is frozen by being immersed in the Freon brine having an ethylene brine layer 2 formed on the liquid surface thereof.

In the present invention described above, the container 4 (e.g., a pipe) containing the object to be frozen (e.g., water) is immersed in Freon-based brine, for example, Freon 11 brine to freeze the object to be frozen, water. ℃
On the other hand, the viscosity does not become large even if the
The liquid surface of Freon 11, which has a low boiling point of 23.7°C, is covered with an ethylene-based ethylene glycol layer 3, which has a high boiling point of about 105°C.
Evaporation of 11 is inhibited by ethylene glycol.

しかもフレオン11は−30℃以下の低温でも粘度

Moreover, since Freon 11 does not have a large viscosity even at low temperatures of −30° C. or lower, the heat exchange efficiency does not decrease, and the object to be frozen in the container 4 can be effectively frozen.

In addition, since the liquid surface of Freon is covered with ethylene glycol, evaporation of Freon is prevented.Therefore, the tank 1 does not need to be a sealed one, and an open tank may be sufficient. The open tank allows for highly efficient refrigeration.

Moreover, since Freon is prevented from evaporating as mentioned above, unlike Freon that evaporates, there is no need to replenish Freon frequently, and only the amount of Freon that has adhered to the object to be frozen and has been removed can be replenished. Since Freon is not heated and there is almost no aging due to deterioration, it can be used for many years, and expensive Freon can be saved and economical refrigeration can be performed. There is.

Further, the pipe serving as the container is not limited to a single pipe, but may be a double pipe or other multiple pipes in which each pipe contains water, which is the object to be frozen.
