Moderate oxygen control constant-temperature humidity conditioning storage container

Abstract

The invention relates to a moderate oxygen control constant-temperature humidity conditioning storage container which is in a square container body structure. A refrigeration chamber is arranged on one inner side of the storage container body, an equipment chamber is arranged between the refrigeration chamber and the other side in the storage container, a plurality of mist nozzles are mounted at intervals and uniformly distributed on the inner top of the refrigeration chamber, a heat exchanger, a temperature sensor, a pressure sensor, a humidity sensor, an O2 sensor and a CO2 sensor are fixedly mounted on the wall of the equipment chamber in the refrigeration chamber, and a moderate oxygen control device, a refrigerator, a humidity conditioner, an air supply electromagnetic valve and an electronic control unit are mounted in the equipment chamber. The storage container is capable of moderately controlling the concentration of oxygen in the container body besides the constant temperature humidity conditioning function, the low-temperature, high-humidity and oxygen-control integrated container environment can better control respiration intensity of fruits and vegetables, and accordingly refreshment time can be prolonged.

Description

technical field [0001] The invention belongs to the field of fresh-keeping technology, and relates to a fresh-keeping technology for fruit and vegetable transportation, in particular to a storage and transportation box with moderate oxygen control, constant temperature and humidity regulation. Background technique [0002] We know that there are five main factors that cause the deterioration of fruits and vegetables: the action of microorganisms, the action of enzymes, oxidation, respiration, and mechanical damage. Generally speaking, temperature is the fastest and most important environmental factor affecting the rate of deterioration of fruits and vegetables. On the basis of the optimum temperature of fruits and vegetables, for every 10°C increase, the rate of deterioration will increase by 2 to 3 times. Although cooling can delay the deterioration of fruits and vegetables, it cannot completely inhibit the effects of the above five factors. In order to achieve freshness p...

AI Technical Summary

Problems solved by technology

Only when the oxygen content is reduced to 2%-7%, can the respiration of fruits and vegetables be inhibited; if the oxygen content is too low, poisoning will occur, and if the oxygen content is too high, it will not meet the fresh-keeping requirements
