Gas regulation composite preservation case for agricultural products

Abstract

The invention relates to the field of agricultural products, in particular to a gas regulation composite preservation case for agricultural products. The preservation case comprises a case body, a plurality of preservation boxes and gas regulation devices in the same number as the preservation boxes, wherein the case body is of a cylindrical structure, a plurality of partition plates are arranged in the case body, a fan-shaped cavity is formed between every two adjacent partition plates, one preservation box capable of being drawn out is arranged in each fan-shaped cavity, the gas regulation devices are mounted on the outer side of the case body, each fan-shaped cavity is provided with one gas regulation device, each gas regulation device comprises a gas storage chamber communicating with the corresponding fan-shaped cavity, a baffle arranged at the communication position of the corresponding gas storage chamber and the corresponding fan-shaped cavity and a gas supplementing mechanism arranged on the corresponding gas storage chamber, and a gas sensor is further mounted in each fan-shaped cavity. According to the preservation case, the gas in the preservation boxes is supplemented and regulated through the gas regulation devices, so that the gas in the preservation boxes is always in an environment suitable for the storage of the agricultural products, the better storage effect of the agricultural products is guaranteed, and the quality is not likely to be affected.

Description

technical field [0001] The invention relates to the field of agricultural products, in particular to a modified atmosphere composite preservation box for agricultural products. Background technique [0002] Modified atmosphere preservation is recognized as the greenest and most environmentally friendly preservation method in the world today. It has good preservation effect, long shelf life, high production efficiency, safety, and environmental protection. warehouse, the air-conditioned storage in the prior art has certain defects and limitations, the existing air-conditioned fresh-keeping box is large in size, high in cost, and consumes high energy, and the transportation of agricultural products is also restricted. There is external gas entering the fresh-keeping box, without gas supplementation, it is easy to cause damage to the agricultural products or affect its quality. The existing fresh-keeping boxes are not suitable for small-scale storage of agricultural products, a...

Problems solved by technology

[0004]According to the above-mentioned patent, the patent does not have an element for supplementing gas in the box, and the change of the environment inside the box caused by the entry of external gas into the box is likely to cause The storage effect of the fresh-keeping box is not good, and it will cause damage to the agricultural products for a long time. Therefore, a device that can replenish the gas in the fresh-keeping box according to the change of the environment is needed at present.
