Problems solved by technology

[0004] Existing cold storages often only have refrigeration and cooling systems. Although some refrigeration systems also have auxiliary heating devices, the storage and preservation temperatures of various fruits and vegetables are quite different. Some fruits and vegetables are stored at higher temperatures, such as bananas, mangoes, pineapples, durians and other tropical fruits. , these fruits and vegetables are stored and kept fresh at a temperature of 8-10°C; some fruits and vegetables are stored at a lower temperature, such as: apples, pears, cherries, dates, spinach, coriander, etc. ℃, the refrigeration system of the existing cold storage cannot guarantee to meet the storage temperature requirements of all fruits and vegetables, and at the same time, the existing technology lacks a temperature adjustment process suitable for storing fruits and vegetables, so that such fruits and vegetables are very prone to chilling damage when stored in the cold storage, and then As a result, such fruits and vegetables cannot be stored in the existing cold storage

Abstract

The invention provides a temperature regulation system of a cold chain device. The system comprises a temperature-regulated oven, a circulating fan, a circulating pump, a refrigeration unit and a monitoring control system. The invention also provides a flexible temperature regulation method of the cold chain device, and the method comprises the following steps: the monitoring control system sets fruit-vegetable storage fresh-keeping parameters according to the requirements of different fruits and vegetables; temperature sensors monitor the temperatures of the outlet of the circulating fan, theinside of the cold chain device and the fruit-vegetable center in real time; the temperature sensors transmit the monitored temperatures to the monitoring control system; and the monitoring control system compares the monitored data to control the working state of the temperature-regulated oven and the refrigeration unit according to the preset fruit-vegetable storage fresh-keeping parameters, and carries out temperature regulation on the air in the cold chain device so as to ensure that the monitored data is consistent with the preset fruit-vegetable storage fresh-keeping parameters, so thatthe storage fresh-keeping quality of fruits and vegetables is improved, and a longer storage fresh-keeping period of the fruits and vegetables is obtained.

Description

technical field [0001] The invention relates to the field of food preservation, in particular to a temperature adjustment system and a flexible temperature adjustment method for cold chain equipment. Background technique [0002] In order to prolong the storage period of fruits and vegetables, it is necessary to have a suitable temperature. At present, people usually use cold chain equipment such as cold storage, refrigerated trucks, etc. to reduce the storage temperature and inhibit the respiration of fruits and vegetables to extend the freshness period of fruits and vegetables. [0003] In the process of realizing the present invention, the inventor finds that there are at least the following problems in the prior art: [0004] Existing cold storages often only have refrigeration and cooling systems. Although some refrigeration systems also have auxiliary heating devices, the storage and preservation temperatures of various fruits and vegetables are quite different. Some ...
