[0002] In terms of storage technology, it is usually stored in the air at room temperature. Some use refrigeration technology, but the cost is high. Some use vacuum packaging, which only reduces the amount of air, and there is still oxygen in it. The effect of heat insulation and light shielding is not obvious. Most of them are small packages, and only compact foods can be stored. Some use cans and glass bottles for packaging, but the cost is high, and it cannot effectively solve the problem of heat insulation, and it is difficult to reuse.

[0003] After searching in the public (announcement) number: CN216103802 U, an agricultural grain storage tank is disclosed, including a storage tank, an isolation plate fixedly connected between the front and rear inner walls of the storage tank, a motor fixedly installed on the left side of the storage tank, the right end of the output shaft of the motor fixedly connected to the stirring shaft, the stirring shaft penetrates the isolation plate and is rotatably connected between the left and right side walls of the storage tank, the outer side of the stirring shaft is fixedly connected to a stirring fan, a refrigerator is fixedly installed in the bottom plate cavity of the storage tank, the refrigerator is connected to the bottom end of the isolation plate, the rear side of the storage tank is slidably connected to a sampling device, the storage tank and the top of the isolation plate are slidably connected to a storage tank sliding cover, the low temperature is transferred to the partition through cooling by the refrigerator, the heat generated during grain storage is absorbed by the partition, the grain is stored in a low temperature environment for a long time to inhibit the growth of pests and microorganisms, and the grain is stirred by the stirring fan, so that the grain can dissipate heat evenly to prevent local excessive temperature from causing pests and mildew.

[0004] Although the above scheme absorbs the heat generated during grain storage through the partition, so that the grain is stored in a low temperature environment for a long time to inhibit the growth of pests and microorganisms, the oxygen in the tank is not completely discharged during the grain storage process. After a period of storage, the microorganisms, pests, etc. in the grain will use oxygen for aerobic activities, affecting the storage quality of the food, and the dependence on electricity is large. Therefore, we propose a storage tank for food storage. Utility Model Content
