Problems solved by technology

[0002] With the continuous development of agricultural technology, people's requirements for the freshness of vegetables are becoming more and more strict, but vegetables need to be picked a period of time in advance before they are sold. Therefore, in order to ensure the market price of vegetables, they need to be kept fresh. The best method is to use the method of spraying chemical reagents to sterilize and disinfect it. This method will not only cause chemical residues, cause secondary pollution to vegetables, and affect the health of people who eat them. cause some economic loss

Abstract

The invention relates to a vegetable fresh-keeping control system, and belongs to the technical field of agricultural storage. The system comprises a storage chamber, carbon dioxide sensors and vacuum sensors are arranged in the storage chamber, the signal lines of the carbon dioxide sensors and the vacuum sensors are connected with the signal input end of the control device, the control outlet end of the control device is connected with a carbon dioxide management valve, a carbon dioxide generator, a vacuum pumping pipeline valve and a vacuum pumping machine. The vacuum pumping device is used to reduce the content of oxygen in the storage chamber and delay the decaying time of agricultural products, carbon dioxide is conveyed to the storage chamber in order to promote limited photosynthesis of vegetables to a certain degree and keep the activity of the vegetables, and the vegetable fresh-keeping control system also has the advantages of simple and reasonable structure, convenience in storage, no secondary pollution and good fresh-keeping effect.

Description

technical field [0001] The invention relates to a vegetable preservation control system, which belongs to the technical field of agricultural storage. Background technique [0002] With the continuous development of agricultural technology, people's requirements for the freshness of vegetables are becoming more and more strict, but vegetables need to be picked a period of time in advance before they are sold. Therefore, in order to ensure the market price of vegetables, they need to be kept fresh. The best method is to use the method of spraying chemical reagents to sterilize and disinfect it. This method will not only cause chemical residues, cause secondary pollution to vegetables, and affect the health of people who eat them. cause certain economic losses. Contents of the invention [0003] Based on the above deficiencies in the prior art, the problem to be solved by the present invention is: to provide a vegetable preservation control system with reasonable design, co...
