Freshness preservation device used for vegetable and fruit transportation

Abstract

The invention provides a freshness preservation device used for vegetable and fruit transportation. The freshness preservation device comprises a box body, a box door hinged to the box body, a control device, a gas concentration detection sensor, a temperature control device, a humidity preservation device, a temperature detection device and a humidity detection device. The gas concentration detection sensor is arranged in the box body and used for detecting the concentration of oxygen in the box body in real time. The temperature control device is used for adjusting the temperature of the interior of the box body. The humidity preservation device is used for adjusting the humidity of the interior of the box body. The temperature detection device is arranged in the box body and used for detecting the temperature in the box body in real time. The humidity detection device is arranged in the box body and used for detecting the humidity in the box body in real time. The control device is connected with a first flow valve, a second flow valve, the gas concentration detection sensor, the temperature control device, the humidity preservation device, the temperature detection device and the humidity detection device and controls the first flow valve, the second flow valve, the gas concentration detection sensor, the temperature control device, the humidity preservation device, the temperature detection device and the humidity detection device to act. By means of the freshness preservation device, the temperature preservation effect and the humidity preservation effect are good, gas exchange can be conducted between the interior and the exterior of the box body, the freshness preservation requirements of vegetable and fruit transportation are met, and the freshness preservation device can be used repeatedly.

Description

technical field [0001] The invention relates to the technical field of article transportation equipment, in particular to a fresh-keeping device for vegetable and fruit transportation. Background technique [0002] At present, the fresh-keeping boxes used for keeping vegetables and fruits mainly include plastic fresh-keeping boxes and foam boxes. Plastic fresh-keeping boxes include fully-sealed incubators and ordinary plastic transfer boxes; foam boxes include fully-sealed and breathable types. Fully-sealed plastic storage boxes cannot exchange gas inside and outside the storage box, which is not conducive to the preservation of fresh agricultural products; ordinary plastic transfer boxes are not conducive to heat preservation and moisture retention in the box, and are also not conducive to the preservation of fresh agricultural products. The fully-closed foam box is the same as the plastic fresh-keeping box of the fully-closed box, which is not conducive to the gas exchang...

AI Technical Summary

Problems solved by technology

Fully-sealed plastic storage boxes cannot exchange gas inside and outside the storage box, which is not conducive to the preservation of fresh agricultural products; ordinary plastic transfer boxes are not conducive to heat preservation and moisture retention in the box, and are also not conducive to the preservation of fresh agricultural products

The fully-closed foam box is the same as the fully-closed plastic fresh-keeping box, which is not conducive to the gas exchange inside and outside the box. But the insulation effect is not good, and it is also a one-time use product
