A kind of batch storage method of agricultural products

Abstract

The present invention relates to a method for storing agricultural products in batches. In the present invention, the agricultural products are placed in a relatively closed shelf cabinet, and the shelf cabinet is placed in a cold storage. After a period of storage, when the CO in the shelf cabinet 2 , O 2 When the content reaches the set threshold, the shelf cabinet will be ventilated, and the air in the shelf cabinet will be replaced with fresh air. Keep fresh, prevent it from dehydration and wilting, and the mist is relatively thin, and will not form obvious dew on the surface of agricultural products (condensation on the surface of agricultural products is easy to cause microbial growth). The invention only exchanges gas and retains moisture during ventilation, which improves storage. Fresh-keeping effect: the method of the present invention is easy to operate, has small workload and stable fresh-keeping effect.

Description

technical field [0001] The invention relates to the technical field of fresh-keeping and storage methods for agricultural products, in particular to a storage method for batch storage of agricultural products. Background technique [0002] Living plant agricultural products with respiration and transpiration are generally stored in cold storage with specific temperature and humidity. At present, there are two common storage methods in the industry: [0003] (1) The agricultural products are directly placed on the shelf cabinet, and the shelf cabinet is placed in the cold storage. Because agricultural products are directly exposed to the air, with the increase of storage time, the agricultural products will suffer from water loss and wilting, and the quality declines rapidly; modern cold storage can alleviate the water loss phenomenon of agricultural products by installing humidifiers to increase the humidity of the cold storage, but at low temperatures , It is difficult to ...

AI Technical Summary

Problems solved by technology

The agricultural products wrapped in fresh-keeping bags can realize self-modified atmosphere preservation and water retention, and have relatively economical and practical fresh-keeping effects. The transparent effect of the fresh-keeping bag, the fresh-keeping effect is unstable

Moreover, due to the respiration of agricultural products, the CO in fresh-keeping bags will decrease with the increase of storage time. 2 content increased, O 2 As the content of the fresh-keeping bag decreases, the harmful gas produced continues to accumulate, which in turn exacerbates the deterioration of the quality of fruits and vegetables; if the fresh-keeping bag has a large volume, although it can be considered to exchange the gas inside it with the outside gas to discharge the harmful gas, but at the same time of gas exchange, The water vapor that will release the agricultural products in the fresh-keeping bags will also be released at the same time, resulting in the continuous dehydration of the agricultural products, and there is still the problem of exacerbating dehydration and wilting
