Description

Vegetable refrigeration method
Technical Field
The invention relates to the technical field of refrigeration, in particular to a vegetable refrigeration method.
Background
Vegetable preservation and storage are always the hot subjects of research in the food industry, and the adopted methods are more, such as cellaring, refrigeration, modified atmosphere preservation, coating preservation, ice block and ice bottle preservation, vacuum freeze drying and the like. In recent years, methods such as carton preservation, microwave preservation, preservative preservation, ceramic preservation, freshness protection of freshness protection bags, microbial preservation, electronic technology preservation and the like are developed in succession. Of these, refrigeration is one of the most common and most suitable methods. The low-temperature refrigeration mainly reduces respiratory metabolism of vegetables and the incidence of pathogenic bacteria by inhibiting the activity of microorganisms and enzymes, thereby achieving the purposes of preventing tissue aging and prolonging the storage period.
The water content of the vegetables is about 65-96%, and the vegetables also contain substances such as saccharides, organic acids, nitrogen-containing substances, glycosides, tannins, aromatic substances, pigments, vitamins and the like, wherein the water content is an important mark for indicating whether the vegetables are fresh or not. When the dry loss (weight loss) of most vegetables exceeds 5%, the obvious characteristics of reduced freshness such as wilting appear. The water evaporation of the vegetables, on one hand, due to respiration, emits a part of water, on the other hand, the air humidity of the storage environment is too low, so that the vegetables are wilted, the commodity value is reduced, and especially when people use a refrigeration device such as a refrigeration device and the like at present, the water content in the air in the refrigeration device is also lower due to the lower temperature in the refrigeration device, so that the water evaporation in the vegetables is faster, and the wilting speed of the vegetables is accelerated; moisture evaporating from the interior of the vegetable enters the walls of the freezer to form solid ice, also known as "frost".
Meanwhile, the vegetables still contain active enzymes after being picked, and the enzymes can perform respiration, decompose nutrients in the vegetables and sometimes synthesize certain substances; generally, when oxygen is available, saccharides or other organic substances in fruits and vegetables are oxidized and decomposed to generate carbon dioxide and water, and a large amount of heat is released; when in oxygen deficiency, the saccharides in the fruits and vegetables can not be oxidized, and only can be decomposed to generate alcohol and carbon dioxide and emit a small amount of heat; in order to obtain enough energy required by life activities when the fruits and vegetables are in an oxygen deficiency state, more nutrition must be decomposed, meanwhile, alcohol generated by oxygen deficiency breathing is remained in the fruits and vegetables, the fruits and vegetables are not changed greatly in appearance, but the fruits and vegetables are rotted and deteriorated, the quality guarantee period of the fruits and vegetables is further shortened, and a great amount of unpleasant odor is generated in the refrigerating device due to the fact that the conventional refrigerating device has no ventilation function.
At present, when people refrigerate vegetables, the most common method is to put the vegetables in a refrigerating device, however, people often find that the vegetables have a wilting condition after one or two days, particularly some green leaf vegetables, the condition is more serious, and some peculiar smells, serious and even rotten stink smells exist in the refrigerating device.
Disclosure of Invention
The invention aims to provide a vegetable refrigeration method, which can effectively reduce the wilting speed of vegetables and reduce peculiar smell, thereby improving the quality guarantee period of the vegetables.
In order to achieve the above purpose, the basic scheme of the invention is as follows: the vegetable refrigeration method adopts a vegetable refrigeration device for refrigeration; the vegetable refrigeration device comprises a refrigeration body and a box cover for covering the refrigeration body, and a rotating shaft is connected between the refrigeration body and the box cover; the cold storage body is internally provided with a spraying structure, a wind sweeping structure, an active mechanism, a passive mechanism and a plurality of layers of placing plates; the spraying structure comprises a spraying box which is connected with the refrigerating body in a sliding way, and a rack and a nozzle for spraying water mist are arranged on the spraying box; the wind sweeping structure comprises a rotating rod which is rotatably connected with the refrigerating body and blades arranged on the rotating rod; the driving mechanism comprises a first bevel gear and a second bevel gear which are meshed with each other, the first bevel gear is connected with the rotating shaft, and the second bevel gear is connected with one end of the rotating rod; the driven mechanism comprises a third bevel gear, a fourth bevel gear and a straight gear, the third bevel gear and the fourth bevel gear are meshed with each other, the fourth bevel gear and the straight gear are coaxially connected, the fourth bevel gear and the straight gear are both rotatably connected with the refrigerating body, the third bevel gear is connected with the other end of the rotating rod, and the straight gear is meshed with the rack;
