[0002] With the rapid progress of science and technology and the transformation of social and economic development mode, grain storage technology focuses on the development direction of "safety, nutrition, green ecology, pollution-free, fresh and healthy". Relying on scientific and technological innovation, scientific grain storage is promoted in an all-round way, low-temperature green grain storage is actively carried out, storage conditions are improved, and the quality of grain storage is guaranteed. We can truly achieve "wide storage of grain, storage of good grain, and storage of grain well" to meet the needs of consumers for food safety, nutrition and health. In order to ensure the storage safety of grain, low-temperature storage technology is usually used in the existing technology. Low-temperature grain storage is a temperature-controlled storage technology that controls the temperature to keep the grain in a low temperature state below 15°C to improve the stability of grain storage.

[0003] For example, publication number CN 208434624 U discloses an air-cooling device for low-temperature grain storage. The air-cooling device comprises a housing, within which is disposed a partition that divides the housing into a first chamber and a second chamber. The partition is provided with an openable and closable air duct switching port. One side of the first chamber is provided with a first air duct on-off device and a first air inlet, while the other side is provided with a first fan and a first air outlet. One side of the second chamber is provided with a second air inlet, and the second chamber is provided with a heat and mass exchange device.
