Description

Fruit and vegetable modified atmosphere storage device

Technical field

The utility model belongs to the technical field of refrigerators, and particularly relates to a device for regulating a refrigerator of fruits and vegetables.

Background technique

Atmospheric storage is now the most advanced method for preservation of fruits and vegetables. It is based on refrigeration, increasing the adjustment of gas composition, inhibiting the respiration of fruits and vegetables, delaying the metabolism of seeds and vegetables, and maintaining the freshness of fruits and vegetables by controlling the conditions of temperature, humidity, carbon dioxide, oxygen concentration and ethylene concentration in the storage environment. Degree and commerciality, extending the storage period of fruits and vegetables and the shelf life of sales. Generally, the modified atmosphere storage can extend the storage period by 2-3 times compared with ordinary refrigeration. There are two main methods for the storage and storage of fruits and vegetables: one is to put different fruits and vegetables in the same stock under low temperature conditions, but the fruits and vegetables of different types and varieties are temperature, humidity, CO2, N2, C2H4, etc. during storage. The requirements of environmental conditions are different, especially the temperature range is very narrow; the storage of fruits and vegetables in the same space can not meet the environmental requirements of different fruit and vegetable products, and the interaction between fruits and vegetables greatly shortens the storage of fruits and vegetables in the air-conditioned refrigerator. The economic benefits are greatly reduced by the ideal period that can be achieved. The other is to build a number of small air-conditioned storage warehouses in the cold storage. Each small air-conditioning storage warehouse stores a kind of fruit and vegetable products, which causes space and economic waste, and is inconvenient and inflexible.

Utility model content

The purpose of the utility model is to provide a fruit and vegetable modified atmosphere refrigerator device to solve the deficiencies in the above scheme.

In order to achieve the above object, the technical solution adopted by the utility model is:

A fruit and vegetable modified atmosphere refrigerator device is mainly composed of a refrigerator, an air conditioner cooler, an air bag, a deodorizer, an N2 generator, a CO2 scrubber, a gas analyzer and a refrigerator body, and the refrigerator body is below the left side of the refrigerator body There is a refrigerator, an air conditioner cooler is arranged on the upper left side of the refrigerator body, and the air conditioner cooler is connected to the refrigerator. An air bag is arranged above the refrigerator body, and a deodorizer is arranged in the upper right corner of the refrigerator body, and the right side wall of the refrigerator body is provided. There is an N2 generator on the side, a CO2 scrubber is arranged under the N2 generator, and a gas analyzer is arranged on the lower side of the refrigerator body.

The refrigerator is provided with a fruit and vegetable rack at a central position in the body.

The side wall of the refrigerator body is provided with an inflatable cuff and a suction cuff.

The utility model has the advantages of simple operation technology and convenient maintenance. The refrigeration equipment microcomputer controls the temperature, automatically starts and stops, no need for special personnel supervision, and the supporting technology is economical and practical. It can not only regulate the temperature and humidity in the library, but also control the content of oxygen, carbon dioxide and other gases in the library, so that the fruits and vegetables in the library are in a dormant state, and the original quality is maintained after the storage.
