Method and device for preserving plants

Abstract

The invention discloses a method and a device for preserving plants, and aims to solve the problem of short preservation time and the like in the prior art. The device comprises a cooling device, an air conditioning device and a liquid adding and reacting device. The plants are preserved for a longer time by adding reaction liquid to adsorb residual gas and CO2, hydrocarbon gas, H2S, nitrogen oxide gas, hydronitrogen gas, ammonium carbonate gas and ammonium nitrate gas which are generated from anaerobic respiration of the plants. In the structure, the cooling device controls a low temperature; the air conditioning device fills nitrogen into a box body and discharges most of the gas except for the nitrogen in the original air simultaneously, so the inner gas is recycled; and the liquid adding device adds liquor to adsorb the residual gas and the gas generated from the anaerobic respiration of the plants, so fruits, vegetables, flowers, edible fungi and living plants can be preserved for a longer time.

Description

technical field [0001] The invention belongs to the technical field of plant preservation, and in particular relates to a plant preservation method and a preservation device used in the storage, transportation and packaging of fruits, vegetables, flowers, edible fungi and living plants. Background technique [0002] With the increase in the quantity and quality of my country's agricultural products, especially the development of the flower industry, and the rapid development of world economy and trade, the storage and transportation of fruits, vegetables, flowers, edible fungi and living plants continue to increase. However, after picking these plants A series of lifting activities will still be carried out. In order to ensure the quality and freshness of these products, air-conditioning, refrigeration and other fresh-keeping techniques are generally used to reduce the storage temperature, and ethylene oxidizers are used to absorb and oxidize ethylene. These methods basically ...

Problems solved by technology

[0002] With the increase in the quantity and quality of agricultural products in our country, especially the development of the flower industry, and the rapid development of world economy and trade, fruits, vegetables, flowers, edible fungi and The storage and transportation volume of living plants continues to increase, but these plants will still carry out a series of lifting activities after picking. In order to ensure the quality and freshness of these products, fresh-keeping techniques such as controlled atmosphere and refrigeration are commonly used to reduce the storage temperature. Using ethylene oxidant to adsorb and oxidize ethylene, these methods basically solve the problems that affect the quality of agricultural products such as cooling and absorbing ethylene, but cannot solve the carbon dioxide gas, hydrogen sulfide gas, and ammonium carbonate gas produced by anaerobic respiration of plants such as flowers , ammonium nitrate gas, nitrogen oxide gas, nitrogen hydrogen compound gas and affect the storage time of plants
