Automatic air-adjusting element and air-adjusting fresh-keeping method for fruits

Abstract

The invention discloses an automatic atmosphere control element and a fruit atmosphere control preservation method thereof, wherein the box bottom, the box wall and a box cover of an atmosphere control box are provided with at least one air hole respectively. Firstly, at least one first long atmosphere control element and one second long atmosphere control element, and a short atmosphere control element are soaked in a liquid, the atmosphere control elements are arranged in the air holes of the atmosphere control box filled with fruits, and the short atmosphere control element is completely plugged into the air hole of the box bottom of the atmosphere control box; one to all the first long atmosphere control elements and the second atmosphere control elements are inserted into a part of the box wall of the atmosphere control box, side holes are exposed, and an atmosphere control instrument is used to introduce carbon dioxide gas into the atmosphere control box; and the atmosphere control box is closed for 20 to 30 hours, and the fruits in the atmosphere control box are preserved in the carbon dioxide gas. The automatic atmosphere control element can perform full-range regulation preservation on the whole circulation area of storage, transportation, and sales of the fruits and so on. The aim of fruit preservation with high carbon dioxide, low oxygen and low temperature can be realized by arranging the automatic atmosphere control element on the atmosphere control box and adopting a novel atmosphere control method combined with automatic atmosphere control and spontaneous atmosphere control.

Description

technical field [0001] The invention relates to an atmosphere-modified component used on a fruit fresh-keeping box, and a method for using the component to carry out controlled-atmosphere preservation of fruits. Background technique [0002] The technology of spontaneous modified atmosphere preservation of fruit has been applied in the market, but there are serious shortcomings in the spontaneous preservation of strawberry and red bayberry, which makes it difficult to apply this technology and directly affects the freshness preservation. In the actual bagging and fresh-keeping storage test of fruit, it was found that when the storage temperature was 0 degrees or 6 degrees, it would take six or seven days to spontaneously form high carbon dioxide gas and low oxygen. The existing spontaneous modified atmosphere fresh-keeping technology cannot form a high carbon dioxide and low oxygen environment in time to control the growth and bacterial growth of strawberries and other fruit...

AI Technical Summary

Problems solved by technology

[0003] The invention provides an automatic air-conditioning component and its method for fresh-keeping of fruit, which is to solve the problem that the traditional air-conditioning fresh-keeping cannot form a high-carbon dioxide and low-oxygen environment in time, and cannot automatically adjust the carbon dioxide concentration and humidity in the air-conditioning box as the external conditions change. question
