Fresh-keeping system and fresh-keeping method based on plasma generation technology

Abstract

The invention discloses a plasma generation technique-based preservation system, which comprises a product processing box, a plasma generating device and an intelligent control device, wherein an agricultural product to be subjected to preservation treatment is arranged in the product processing box; the plasma generating device is communicated with the product processing box, and is used for generating a corresponding active gas and delivering the generated reactive gas to the product processing box so as to carry out preservation treatment on the agricultural product to be subjected to preservation treatment according to the variety of the agricultural product to be subjected to preservation treatment; the intelligent control device is used for controlling operation parameters of the plasma generating device so that the plasma generating device can generate a corresponding active gas. The invention also discloses a plasma generation technique-based preservation method. By using the preservation system and the preservation method, an active gas which meets requirements can be produced, and a variety of agricultural products can be quickly subjected to preservation treatment.

Description

technical field [0001] The invention relates to the technical field of fresh-keeping treatment of agricultural products, in particular to a fresh-keeping system and a fresh-keeping method based on plasma generation technology. Background technique [0002] At present, the preservation methods of agricultural products are mainly divided into chemical methods and physical methods, which control the internal factors and external factors of fruit rot respectively. [0003] Chemical methods mainly refer to fresh-keeping agents. At present, the commonly used preservatives are: paint coating agent, ethylene treatment agent (absorbent), bactericidal antiseptic preservative, etc. The current development trend of film preservation is green and environmental protection, but it is not suitable for large-scale fruit preservation; absorbents are mainly physical adsorption, and there is a risk of desorption; bactericidal preservatives are mostly used for spraying or soaking on the surface...

AI Technical Summary

Problems solved by technology

But the device used is to put fruit in the middle of the double DBD, and the double DBD is limited by its structure, it is impossible to put larger fruits such as citrus and oranges in the middle, and its cost is high, and the processing capacity is too low each time. These limitations make it impossible to implement large-scale application

[0007] At this stage, the use of plasma for agricultural products is mainly to adjust the atmosphere of the storage environment to achieve the fresh-keeping function. For example, Ma Tingjun used plasma to adjust the environment in the storage room in "A Method of Low-temperature Plasma for Fruit and Vegetable Fresh-keeping". The discharge product of the device is uncontrollable, and it is impossible to quickly, directly and effectively treat the surface of agricultural products; Zhang Pingping combined plasma into the decompression storage in "Plasma Decompression Storage and Fresh-keeping Methods", but it is also an adjustment for the storage environment , the plasma concentration is low, and the plasma discharge products are uncontrollable, so it is impossible to quickly, directly and effectively treat the surface of agricultural products
