Problems solved by technology

[0002] Controlled atmosphere storage is an advanced fruit storage technology in the world at present. Although the storage effect is good, the equipment investment and operation costs are high, and storage using standard controlled atmosphere equipment is rarely used in my country.
However, the spontaneous controlled atmosphere storage of plastic film tents is widely used in my country. The disadvantage is that the gas composition in plastic film tents is mainly regulated by fruit respiration, and it is difficult to control the gas composition at the ideal index.

Embodiment

[0010] Such as figure 1 Shown, with angle iron welding one below is rectangle, above is two wall frames 1 of triangle, and each wall frame 1 rectangular frame inner side is welded four plug slots 4, is welded with the angle iron 5 of plug or running water pipe at both ends 3. Connect the two wall frames 1, wherein the uppermost running water pipe 2 has some small air intake holes. After the bracket connection assembly is completed, in order to prevent the plastic film from being damaged by the angle irons, wrap all the angle irons and joints with a film. The assembled bracket is placed on the 0.12mm polyethylene plastic film pre-laid on the ground, and then covered with a 0.12mm polyethylene plastic film tent, and the valve needle air inlet 6 and the valve needle air outlet 7 passing through the plastic film are set. The four corners of each side of the plastic film tent are respectively provided with four analysis sampling ports 8 for sampling and analyzing the gas component...

Abstract

The invention relates to an atmosphere controlling device for controlled atmosphere (CA) storage of fruit. The invention provides a simple and easy-to-use atmosphere controlling device with good effect for the plastic film house CA storage of fruits, especially apples. The device comprises a support assembly, a plastic film house, a gas inlet pipe and a gas outlet pipe. The gas inlet pipe and the gas outlet pipe are threaded through the plastic film house with car gas needles. The gas inlet pipe is connected to a nitrogen steel cylinder or other nitrogen sources for atmosphere controlling. The gas outlet pipe is conducted outside of the house by using a long plastic tube. The end of the tube is provided with a syringe needle The atmosphere controlling device has advantages of simple structure, low production cost, convenient use, and good effect.

Description

technical field [0001] The invention belongs to the technical field of storage and preservation of agricultural products, and provides a simple, easy-to-use and effective air-regulating device for storing fruits, especially apples, in a plastic film tent. Background technique [0002] Controlled atmosphere storage is an advanced fruit storage technology in the world at present. Although the storage effect is good, the equipment investment and operation costs are high, and storage using standard controlled atmosphere equipment is rarely used in my country. However, the spontaneous controlled atmosphere storage of plastic film tents is widely used in my country. The disadvantage is that the gas composition in plastic film tents is mainly regulated by fruit respiration, and it is difficult to control the gas composition at an ideal index. For this reason, the present invention proposes an air conditioning device for controlled atmosphere storage of fruit, which performs air con...
