Description

The present invention relates to a storage facility applied to long-term storage and a method thereof by storing a large amount of food together with snow and refrigeration and forming an electrostatic field in each food storage device.

For example, as disclosed in Patent Document 1, a method of forming an electrostatic field in a refrigerator and refrigerated fresh food products in this atmosphere for a long period of time is widely known. As the electrostatic field forming means, a high-voltage electrostatic transformer is used, one pole on the secondary high-voltage side is insulated, and the other pole is connected to a shelf or case of a conductive metal material. Thereby, negative electrons due to electrostatic induction are applied, and the fresh food placed on the shelf can be refrigerated and stored in an electrostatic field atmosphere. In this case, the negative-electron generation condition is that the current value on the primary side of the high-voltage electrostatic transformer 100V is 0.02A to 0.3A per 1 m ^{2 of the} electrode, and the secondary side voltage that satisfies the primary side current value is 5000V to 20000V.

In the electrostatic field atmosphere formed in the refrigerator, it is usually stored in a temperature range of 3 ° to -3 °, but it does not freeze even at a low temperature of about -5 ° C. For this reason, it can be stored in a fresh state for a long period of time without causing cell destruction during freezing, and is a very suitable storage method for storing fresh food products.

  In a structure where the refrigerator interior is formed in an electrostatic field atmosphere, depending on the size of the refrigerator and the number, size, and shape of the stored items, there are structurally difficult problems to store a large amount of food such as harvested vegetables and fruits. is there. For example, when food is intended for long-term storage, the power consumption of both the refrigerator and the electrostatic field generator greatly affects the cost. Further, in the individual refrigerated storage by the refrigerator, temperature change due to opening and closing of the door and deterioration due to drying, which is an essential problem of the refrigerator, are also major factors hindering long-term storage.

Furthermore, in the conventional electrostatic field processing apparatus, the entire inner wall in the refrigerator is covered with a metal plate via a plastic insulator such as polyvinyl chloride, and an electrostatic field atmosphere is formed in the entire interior. For this reason, there is a problem that the electrostatic field conditions vary depending on the place where the food is placed, and the quality is not constant due to different storage conditions. In particular, this becomes more prominent as the apparatus becomes larger, and has become a major bottleneck when storing a large amount of foods collectively.

  In view of the above situation, the present inventors have finally completed the present invention as a result of intensive studies, and the feature thereof is that food is refrigerated by depositing snow in a snow installation zone provided inside.

The object of the present invention is to preserve food for a long time by placing it in an electrostatic field atmosphere. The snow installation zone may be provided on the floor of the building, or may be formed in the ground and food may be placed thereon.

  The “food storage tool” is a container-shaped storage tool for storing food, and the body is formed of a conductor to form an electrostatic field atmosphere therein. A large number of food containers are installed in the facility space to store large quantities of food. This is to make the electrostatic field conditions as uniform as possible by dividing the food. The size of the food container is about 1000 mm to 2000 mm in length, width, and height.
