Fresh-keeping device and fresh-keeping control method

Abstract

The invention provides a fresh-keeping device. A fresh-keeping shell inner cavity is used as an accommodating cavity; a photosynthetic fresh-keeping device, an ethylene decomposition device, a fan anda gas sensor are respectively and electrically connected to a control panel through wire harness, and are placed in the accommodating cavity; and two sides of the fresh-keeping shell are separately provided with an air inlet and an air outlet. At the same time, the invention also provides a fresh-keeping control method of the fresh-keeping device, and the ethylene concentration value of gas is collected by the gas sensor and fed back to the control panel; the control panel compares and analyzes the received ethylene concentration value with the set value, and separately sends opening / closingcommands to the photosynthetic fresh-keeping device, the ethylene decomposition device and the fan according to the comparing and analysis result, and ethylene is absorbed by the wind cycle in the accommodating cavity formed by cooperation of the fan, the air outlet and the air inlet, and the ethylene is decomposed by the ethylene decomposition device, and carbon dioxide generated by the decomposition provides guarantee for the carbon source required for photosynthesis of fruits and vegetables. The device can be flexibly applied according to specific scenes, and has a good fresh-keeping effect.

Description

technical field [0001] The invention relates to the field of food preservation, more specifically to a preservation device and a preservation control method. Background technique [0002] Fruits and vegetables will undergo physiological after-ripening after picking, resulting in accelerated loss of nutrients. In the final analysis, the main reason is ethylene, which as a ripening gas can lead to accelerated respiratory metabolism of fruits and vegetables. [0003] At present, photosynthetic fresh-keeping and ethylene removal technologies have been used on a large scale in refrigerators, but the effect is limited in actual use. Attributed to the reason: [0004] 1. There is no effective carbon source in the refrigerator; [0005] 2. The ethylene produced by fruits and vegetables will decompose chlorophyll, which will greatly reduce the efficiency of photosynthesis. Contents of the invention [0006] The present invention aims to solve the above-mentioned technical probl...
