Technical Field

[0001] This invention relates to the field of grain storage technology, and in particular to a temperature-controlled air supply device. Background Technology

[0002] During storage, the quality and stability of grains are significantly affected by temperature changes. High temperatures accelerate the respiration and metabolic processes of grains, leading to a decline in grain quality and increased losses.
