Food fresh-keeping method and fresh-keeping refrigeratory

Abstract

A method for food fresh-keeping and the fresh-keeping refrigerating room, comprising the refrigerating, humidifying and deoxidation the food in the refrigerating room; the said deoxidation step is: removing the oxygen in the air when the oxygen concentration amounting to a certain value and then loading the food into the refrigerating room; and the said humidifying step is: humidifying the air when the degree of humidity is under a certain value. The fresh-keeping by this method and in this refrigerating room can maintain for a long time for the proper value of the oxygen content, humidity, temperature and carbon dioxide content in the refrigerating room air, particularly by humidifying at a low temperature can reach a good humidifying effect in the refrigerating room with a low temperature, solving the problem existing in the humidifying for a long time; furthermore, the deoxidation cost can be deduced largely by burning to remove oxygen. The device is most suitable for the Sea Island and ocean-going ship for transport which demands the food fresh-keeping.

Description

technical field [0001] The invention relates to a cold storage, in particular to a food fresh-keeping method and a fresh-keeping cold storage. Background technique [0002] As people's requirements for food are getting higher and higher, people hope that the food that has been transported for a long time in different places, especially distant places, can keep the original fresh taste as much as possible. In addition, residents on some islands need to transport food from land, mainly fruits and vegetables, and store them in cold storage. The food supplied by the ocean-going crew is also kept in cold storage. In a word, the existing food fresh-keeping warehouses use freezing (low temperature) or filling nitrogen to reduce oxygen to prevent food from rotting, so as to achieve the purpose of fresh-keeping. However, food, especially fruits and vegetables, will lose moisture if they are frozen for a long time, so they cannot keep fresh. the goal of. Although this kind of humid...

AI Technical Summary

Problems solved by technology

In a word, the existing food fresh-keeping warehouses use freezing (low temperature) or filling nitrogen to reduce oxygen to prevent food from rotting, so as to achieve the purpose of fresh-keeping. However, food, especially fruits and vegetables, will lose moisture if they are frozen for a long time, so they cannot keep fresh. the goal of

Although this kind of humidity has not rotted and deteriorated, it has lost its fresh taste due to the loss of more water.

In addition, the cost of reducing oxygen by filling nitrogen is firstly high, and secondly, it cannot be completely sterilized, and constant humidity cannot be guaranteed. After all, the humidity of the fresh-keeping store will decrease over time, which greatly affects the freshness of food.

The effect is not ideal

[0003] Chinese patent ZL03209641.0 proposes a concept of constant temperature, constant pressure, and constant humidity food fresh-keeping cold storage, but the disclosed technology lacks specific technical means for sterilization, oxygen removal, and cannot achieve constant temperature, constant pressure, and constant humidity food preservation.
