Fruit and vegetable refrigerating and fresh-retaining container with the function of pressure reduction

Abstract

The invention discloses a fruit and vegetable refrigerating and fresh-retaining container with the function of pressure reduction; the structure thereof comprises a pressure reduction refrigerating room and an equipment installing room; the pressure reduction refrigerating room is internally provided with heat exchange equipment; the equipment installing room is internally provided with refrigerating equipment, automatic control equipment and a manual operation drainage system for discharging defrost water of the heat exchange equipment; and the equipment installing room is also provided with a pressure reduction system and a fresh air supplementing system which are in a vacuum state in respect to the pressure reduction refrigerating room. The invention has the beneficial effects that the transportation fresh-retaining effect of fruit and vegetable under the storage and transportation mode of hypoxia or ultra-hypoxia special adjusting gas, compared with regular gas adjusting storage and transportation, the pressure reduction storage and transportation can accelerate ethylene or other volatile gas in the tissue of the fruit and vegetable to disperse outwards, sustains ageing of fruit and vegetable tissue, prevents the tissue from softening, and reduces the occurrence of physiological diseases of fruit and vegetable during storage and transportation. The fast cooling of fruit and vegetable can be realized in the pressure reduction refrigerating room, thus the synchronous processing of gas partial pressure is fast changed.

Description

technical field [0001] The invention relates to a refrigerated and fresh-keeping container for fruits and vegetables, in particular to a refrigerated and fresh-keeping container for fruits and vegetables with a decompression function. Background technique [0002] The application of container transportation is a modern transportation method that appeared in the 1960s. In order to meet the shortage, supply the market or trade at home and abroad, most fruits and vegetables need to be transported at different distances and times, but fruits and vegetables are perishable and difficult to store fresh agricultural products, so long-distance normal temperature and normal pressure transportation is very important for maintaining the quality of fruits and vegetables. Quality and shipping times are not guaranteed. For this reason, in the circulation of fruits and vegetables, refrigerated containers that can control the temperature have been used for transportation, which has achieved...
