Temperature intensification treatment and cold storage of multifunctional miniature fruits and vegetables

Abstract

The invention discloses a multifunctional micro-type fruit and vegetable temperature shocking treatment and storage refrigeration house which comprises a fruit and vegetable storage room, a first heat exchanger, a house inner side sliding door, a second heat exchanger, a fruit and vegetable treatment room, a first control valve, a second control valve, a throttling device, a third heat exchanger, a third control valve, a fourth control valve and a compressor. The second heat exchanger is used as an evaporator, and refrigerating fluid evaporates, absorbs heat and cools air in the fruit and vegetable treatment room to be temperature needed by fruit and vegetable cold shock treatment for the cold shock treatment. The second heat exchanger is used as a condenser, and the refrigerating fluid condenses, releases the heat and heats the air in the fruit and vegetable treatment room to temperature needed by fruit and vegetable heat shock treatment for the heat shock treatment. After the fruit and vegetable cold shock treatment or the fruit and vegetable heat shock treatment is finished, fruits and vegetables are directly moved into the storage room to be stored through the sliding door on a separation structure. When no fruits and vegetables need to be treated, the four control valves are closed, and a system operates in a conventional refrigeration house mode. Compared with the prior art, the multifunctional micro-type fruit and vegetable temperature shocking treatment and storage refrigeration house saves overall equipment cost investment, and effectively improves the primary energy ratio of the system.

Description

technical field [0001] The invention belongs to the field of fruit and vegetable pretreatment and refrigeration, and more specifically relates to a miniature cold storage that utilizes an extra heat exchanger and a control valve of a refrigeration system to realize the functions of cold shock treatment, heat shock treatment and storage of fruits and vegetables. Background technique [0002] At present, cold storage is one of the most important methods of keeping fruits and vegetables fresh in various countries, and the total capacity of cold storage in my country is also increasing year by year. However, refrigerating fruits and vegetables alone often cannot achieve the best fresh-keeping effect, and certain fruit and vegetable pretreatment methods are needed to meet the requirements. As people pay more and more attention to food safety and their own health, physical pretreatment methods with the advantages of non-toxic and pollution-free are getting more and more attention....

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to overcome the deficiencies of the prior art, to provide a micro cold storage based on multiple heat exchangers and control valves, which can realize the functions of cold shock treatment, heat shock treatment and storage of fruits and vegetables at the same time, so as to overcome the cold shock treatment or heat shock treatment of fruits and vegetables. Time-consuming and labor-intensive, additional energy consumption and reduced fruit and vegetable preservation effect caused by shock treatment and then transported to cold storage
