Fruit and vegetable fresh-keeping method and system

Abstract

The invention relates to a fruit and vegetable fresh-keeping method and system. The method comprises the following steps: controlling and maintaining the temperature of a storehouse within a preset temperature range; to-be-stored fruits and vegetables are classified into different fresh-keeping categories according to fresh-keeping requirements of the fruits and vegetables, and the different fresh-keeping categories correspond to different fresh-keeping grades respectively; fresh-keeping devices corresponding to fresh-keeping categories are adopted to store fruits and vegetables, and the fresh-keeping devices of different fresh-keeping categories provide modified atmosphere fresh-keeping environments matched with the built-in fruits and vegetables; and storing the fresh-keeping devices of different fresh-keeping types in the storeroom. According to the storage time limit of the fruits and vegetables, various fresh-keeping technologies are adopted and combined with the special-shaped storeroom, so that the fresh-keeping effect and edible quantity of the fruits and vegetables are effectively improved, and the fresh-keeping space provided by ships and the like is also effectively utilized.

Description

technical field [0001] The invention relates to the technical field of freshness preservation, in particular to a method and system for preservation of fruits and vegetables.

Problems solved by technology

However, on the one hand, as a storage warehouse for supplying fruits and vegetables to the crew on the ship, it is necessary to frequently open and close the warehouse door to take the fruits and vegetables. Frequent opening and closing of the warehouse door leads to the destruction of the air-conditioned environment, thereby reducing the freshness of the fruits and vegetables; on the other hand, The fruits and vegetables carried on the ship have the characteristics of many varieties, and the single controlled atmosphere environment provided by the controlled atmosphere refrigerator cannot meet the freshness requirements of all varieties of fruits and vegetables, so the advantages of the controlled atmosphere preservation method cannot be fully utilized
