Controlled atmosphere storage method of farmproduces and application

Abstract

The invention discloses a controlled atmosphere storage method of farmproduces. The controlled atmosphere storage method comprises the steps of subpackaging the farmproduces, performing pretreatment and performing controlled atmosphere storage, wherein the controlled atmosphere storage comprises steps of conveying farm products pretreated in the step (2) into a controlled atmosphere refrigerationhouse which is cleaned and disinfected, charging high-concentration gas, performing airtight maintaining, adjusting the concentration of O2 and the concentration of CO2 in the controlled atmosphere refrigeration house to controlled atmosphere storage conditions of different farm products through controlled atmosphere equipment, then performing airtight controlled atmosphere storage, in the controlled atmosphere storage process, and performing intermittent charging of high-concentration gas so that the controlled atmosphere storage conditions are recovered to the controlled atmosphere storage state of different farm products. According to the airtight characteristics of the controlled atmosphere refrigeration house, firstly the farm products are pretreated, and then high-concentration CO2 and high-concentration NO are used for performing intermittent treatment on the farm products, so that the farm products are prevented from being invaded by diseases and insect pests or becoming rottendue to high airtight and high wet environment in the storage process, the post-harvest physiology of the farm products after being picked is adjusted, and the storage and transportation and goods shelf life of the farm products is prolonged.

Description

technical field [0001] The invention belongs to the technical field of fresh-keeping of agricultural products, in particular to a method and application of controlled-atmosphere storage of agricultural products. Background technique [0002] Farm produce refers to items produced in agriculture, such as tobacco leaves, melons, fruits, vegetables, peanuts, corn, and local specialties in various regions. In the process of storage and transportation, post-harvest agricultural products lose external nutrient supply, but their own life activities are still going on, so they will soften, age, and be infected by microorganisms, which will lead to deterioration and rot, and serious losses. The types of existing fresh-keeping technologies for agricultural products mainly contain the following methods: one is cold storage, the other is low-temperature and high-humidity fresh-keeping, and the third is to feed inert gas and carry out low-temperature fresh-keeping. Temperature is one of ...

Problems solved by technology

[0008] However, in the process of controlled atmosphere storage of agricultural products, the above method is used in the airtightness of the controlled atmosphere warehouse, which is easy to cause a large number of spoilage bacteria to spread and cause losses; secondly, most of the current controlled atmosphere storage methods Both use high-concentration CO before storing agricultural products 2 , NO treatment of agricultural products, the storage period is no longer used, because the agricultural products are in high concentration CO for a long time 2 , NO environment will cause physiological diseases; again, in the process of operation, CO is often used 2 , Ozone gas is passed into the air-conditioning cold storage for sterilization treatment, but due to the high sealing of the air-conditioning storage, it often causes corrosion to the high-precision accessories of the air-conditioning storage. Once there is a problem with the temperature and gas content sensors, it will cause the temperature and gas in the storage content disorder, resulting in huge losses

Moreover, most of the currently disclosed controlled atmosphere storage methods are aimed at the preservation of a single agricultural product, and there are fewer varieties of agricultural products that can be stored in a limited space, which increases storage costs.
