Freshness preservation device and system and control method

Abstract

The invention relates to a freshness preservation device and system and a control method and belongs to the technical field of storage and freshness preservation. The freshness preservation device comprises a box body and a box door. The box body comprises a storage chamber, an auxiliary machine chamber and a control chamber. The auxiliary machine chamber is internally provided with a nitrogen production assembly, a refrigeration module, a humidification assembly and an air channel pipe. The air channel pipe comprises an air inlet pipe and an exhaust pipe. One end of the air inlet pipe communicates with the nitrogen production assembly, and the other end of the air inlet pipe is arranged in the storage chamber. One end of the exhaust pipe is arranged in the storage chamber, and the other end of the exhaust pipe is arranged outside the box body. The air inlet pipe is provided with a first solenoid valve, and the exhaust pipe is provided with a second solenoid valve. The control chamberis internally provided with a control module. The storage chamber is internally provided with inflating bags and temperature sensors. The nitrogen production assembly is connected with the inflating bags. The control module is connected with the nitrogen production assembly, the refrigeration module, the humidification assembly, the temperature sensors, the first solenoid valve and the second solenoid valve. By means of the freshness preservation device, freshness of articles stored in the storage chamber is guaranteed through multiple freshness preservation technologies.

Description

technical field [0001] The invention belongs to the technical field of storage and preservation, and in particular relates to a preservation device, system and control method. Background technique [0002] With people's pursuit of health preservation and healthy life, the demand for high-quality fresh fruits and vegetables is also increasing. As one of the most effective storage and preservation methods for fruits and vegetables recognized internationally, modified atmosphere preservation is a method to achieve freshness by improving the gas composition of the storage environment. However, at present, the functions of controlled atmosphere devices in my country are relatively single, and the cost of corresponding equipment is high, which is common in large quantities of single-variety fruits and vegetables stored for a long time. Traditional low-temperature and cold storage methods reduce the bacteria's spoilage effect on food by reducing the reproduction and metabolism of ...
