Description

Freshness Keeper {COOLING MAINTAINING APPARATUS}

The present invention relates to a freshness maintaining device, and more particularly, to maintain a large amount of food, such as tofu, and fruits such as tofu and fruit, such as tofu, and flowers to be kept in the decoration for a long time, and to keep cold humidification The present invention relates to a freshness maintaining device capable of maintaining freshness for a long time.

The freshness maintaining device conventionally used is to generate compressed air by an air compressor, and to maintain the freshness of the reservoir by spraying the compressed air together with water through a nozzle.

However, since the freshness maintaining device directly sprays / sprays water and compressed air through the nozzle, noise caused by the injection of compressed air is generated, and the temperature around the air rises due to the heat generated during operation of the air compressor. There was this.

In addition, the conventional freshness maintaining device is humidified by compressed air and nozzles, so that humidification in a limited area, that is, a narrow area, is possible, but it is difficult to simultaneously maintain a large amount of storage freshness. Since it is sprayed by spraying, water that has not been sprayed has been in direct contact with the reservoir. In particular, fruits or flowers, such as when the water directly contact the surface, the area is rapidly damaged and the value of the product falls, there was a problem that can not maintain the freshness.

In addition, it is possible to humidify a wide range by increasing the injection pressure, but if the injection pressure is increased in this way, noise is generated in the storage space severely, safety problems occur, and storage is caused by noise in the storage space. There were various problems such as adversely affecting the sieve. Further, even when humidified, a phenomenon in which the periphery (upper part) of the product became dry under the influence of compressed air occurred. Of course, when a plurality of spray nozzles are installed in a storage space, this problem can be solved, but there is a problem in that the installation cost and equipment cost are increased to increase the economic burden.

In addition, there is also a storage container provided with a refrigerant circulation device in the container to be humidified without compressed air, but the storage container is small and can maintain a small amount of storage freshness, but can not store a large amount of storage, Due to the characteristics of the integrated refrigerant circulation device, there are various problems such as not being able to use a large capacity.

The present invention has been made in view of the above problems, and an object of the present invention is to provide a freshness maintaining device capable of freshly preserving / maintaining a storage material such as food and flowers such as tofu, vegetables and fruits for a long time.

Still another object of the present invention is to provide a freshness maintaining device capable of maintaining optimal freshness by supplying misted water of 2 to 6 ° C. to a storage material.
