a controlled atmosphere warehouse

Abstract

The invention discloses an air-conditioned cold store. The air-conditioned cold store comprises an air-conditioned cold store body and a compressor unit. The air-conditioned cold store body is a sealed cuboid, a separating plate is arranged inside the air-conditioned cold store body and divides the internal space of the air-conditioned cold store body into a storage chamber and an operation chamber, and the storage chamber and the operation chamber are independently sealed and respectively provided with sealing doors. A control device, an ozone machine, an oxygen and carbon dioxide detection device and a nitrogen device are arranged inside the operation chamber, and the ozone machine, the oxygen and carbon dioxide detection device and the nitrogen device are respectively output into the storage chamber through sealing pipelines. A fan is arranged inside the storage chamber and connected with the compressor unit outside the air-conditioned cold store through an air supply pipeline. The air-conditioned cold store can move independently when being separated from the compressor unit and can well solve the problem of cold storage and freshness preservation in the long-time and long-distance conveying process of fruits and vegetables. The air-conditioned cold store is simple in structure, easy to maintain and good in market promotion prospect.

Description

technical field [0001] The invention relates to the field of refrigeration and preservation of vegetables and fruits, in particular to a controlled atmosphere storehouse. Background technique [0002] Traditional fruit and vegetable storage and preservation methods include simple storage, ventilated warehouse storage, radiation preservation, chemical preservation, and cold storage storage. Simple storage and ventilated storage have simple storage equipment and low investment, but the storage effect is poor, the storage period is short, and the rot loss is serious. Radiation and chemical preservation are applicable to some fruits, but due to radiation and chemical residual pollution, not all fruits and vegetables can be applied. [0003] Controlled atmosphere storage, also known as controlled atmosphere storage, is the most advanced storage method for fruits and vegetables. It is on the basis of cold storage, which increases the adjustment of gas components. By controlling ...

AI Technical Summary

Problems solved by technology

Existing controlled atmosphere warehouses use nitrogen generators to produce high-purity nitrogen gas, inject nitrogen and cooperate with deoxygenation equipment to establish a low-oxygen controlled atmosphere environment, but the construction and operation costs of such controlled atmosphere warehouses are relatively high, and most of them use The large storage space will lead to a long time of air conditioning, which is not suitable for short-term storage, especially for the storage of fruits and vegetables

Moreover, the existing controlled atmosphere warehouses are all fixed devices and cannot be transported for long distances, which virtually reduces the promotion and use of controlled atmosphere warehouses.
