[0001] CURING SYSTEM OF COLD STORAGE AND METHOD OF CURING [0002]

[0001] The present invention relates to a crying system for a cryogenic storage which is a type of building for storing low temperature of agricultural and marine products, and particularly relates to a cooling (low temperature) state in which agricultural and marine products can be stored at a low temperature and a low temperature And more particularly to a curing system of a storage room.

Generally, a low-temperature storage tank is used, in which an air conditioning facility that performs a refrigeration cycle function is installed in a storage space to store and store the freshness of agricultural products or foods for a long period of time, so that the internal temperature of the storage space can be set at a low temperature.

Such low-temperature reservoirs are maintained at a low temperature of -5 ° C to 5 ° C depending on the characteristics of stored foods and agricultural products, so that foods that require cryopreservation, such as unprocessed agricultural products or foods containing a large amount of water, As a result of fresh storage and shipment, it is possible to provide consumers with fresh foods and to obtain economical advantages by controlling the date of dispatch as a supplier. As a prior art related to such a low temperature storage, 2005-0100417 (Patent Document 1) and Korean Patent Laid-Open Publication No. 2008-0087609 (Patent Document 2).

However, such a conventional low-temperature storage tank has a problem that a curing chamber such as a crop or the like is separated from a low-temperature storage chamber

Curing refers to a treatment process for preventing agricultural products from being damaged by pathogens caused by low temperature storage by curing the surface wounds generated during harvesting at a high temperature for a certain period of time before being stored in a low temperature storage tank For example, in the case of agricultural products such as sweet potatoes, which are rich in moisture and sugar, curing is carried out at 32-35 ° C and 85-90% humidity for 3-4 days after harvest, Layer can be formed, and long-term low-temperature storage is possible.

Therefore, conventionally, the agricultural products are put into the curing treatment room and cured, and then the cured products are transported to the low-temperature storage room and then stored at a low temperature. In such a transportation process, unnecessary time and labor are consumed, There is a problem in that energy loss due to transportation equipment operation is not economical and there is a problem that the effect of curing treatment is reduced when the cured agricultural product is in contact with the outside air again
