Vegetable refrigeration apparatus

Abstract

The invention relates to the field of refrigeration technology, specifically to a vegetable refrigeration apparatus. The vegetable refrigeration apparatus comprises a refrigeration body and a tank cover used for covering the refrigeration body. Several layers of placing trays are arranged inside the refrigeration body. The vegetable refrigeration apparatus also comprises a spray structure, a wind sweeping structure, a driving mechanism and a driven mechanism. A rotating shaft is connected between the refrigeration body and the tank cover. The spray structure comprises a spray box which is slidingly connected with the refrigeration body. The spray box is equipped with tooth bar and a nozzle used for water spray. The wind sweeping structure comprises a rotating rod which is rotatablely connected with the refrigeration body and blades arranged on the rotating rod. The driving mechanism comprises a first bevel gear and a second bevel gear which are intermeshed. The driven mechanism comprises a third bevel gear, a fourth bevel gear and a spur gear. By the refrigeration apparatus in the technical scheme, vegetable wilting speed can be effectively reduced and peculiar smell can be minimized. Thereby, shelf life of vegetables is prolonged.

Description

technical field [0001] The invention relates to the technical field of refrigeration, in particular to a vegetable refrigeration device. Background technique [0002] Refrigeration is one of the main forms of modern fruit and vegetable storage. Low-temperature refrigeration mainly reduces the respiratory metabolism of vegetables and the incidence of pathogenic bacteria by inhibiting the activity of microorganisms and enzymes, so as to prevent tissue aging and prolong the storage period. [0003] The moisture content of vegetables is about 65% to 96%. It also contains sugars, organic acids, nitrogenous substances, glycosides, tannins, aromatic substances, pigments, vitamins and other substances. Among them, moisture is an important indicator of whether vegetables are fresh. When the dry consumption (weight loss) of most vegetables exceeds 5%, obvious features such as wilting and freshness decline will appear. The water evaporation of vegetables, on the one hand, is due to r...

AI Technical Summary

Problems solved by technology

The water evaporation of vegetables, on the one hand, is due to respiration, which emits part of the water, and on the other hand, the air humidity in the storage environment is too low, which causes the vegetables to wilt and reduces the commodity value, especially when people are using refrigerators and other refrigeration devices. , due to the low temperature inside the refrigerator, the moisture content in the air inside the refrigerator is also low, which accelerates the evaporation of the water in the vegetables and accelerates the wilting speed of the vegetables; the water evaporated from the inside of the vegetables enters the refrigerator wall to form solid ice , which is commonly referred to as "frost"

[0004] At the same time, vegetables still contain active enzymes after picking. These enzymes can perform respiration, decompose nutrients in vegetables, and sometimes synthesize certain substances; generally, sugars or other organic substances in fruits and vegetables are oxidized when there is oxygen Decompose, produce carbon dioxide and water, and release a lot of heat; when there is a lack of oxygen, sugars in fruits and vegetables cannot be oxidized, but can only be decomposed to produce alcohol, carbon dioxide, and release a small amount of heat; when fruits and vegetables are anoxic, in order to obtain enough energy for life activities, More nutrients must be decomposed. At the same time, the alcohol produced by anoxic respiration remains in the fruits and vegetables. The appearance of the fruits and vegetables does not change much, but the inside of the fruits and vegetables has actually deteriorated, which not only further reduces the shelf life of the fruits and vegetables, but also because the current refrigerators do not The ventilation function also produces a lot of unpleasant odors inside the refrigerator
