The invention relates to a gradient dehydration grain dryer. The vibrating stratifier is used to stratify the grain according to the particle size and weight, and the stratified grain enters the drying bucket of the next layer from top to bottom; the drying bucket has vibration, so that the grain inside it It is also layered according to the particle size and weight. The grains that are more thoroughly dried will gradually move up to the edge of the drying hopper due to the decrease in moisture, so that the drier grains can enter the edge of the drying hopper preferentially, while The grain with high humidity is in the center of the drying hopper; the drier grain enters the next layer of the drying hopper and gradually dries; it can avoid the problem of uneven drying caused by a single drying; secondly, when drying, the bottom layer The drying hoppers in the upper layer use hot air directly, while the drying hoppers on the upper layer use the waste heat of the hot air used up in the next layer in turn, so that on the one hand, heat can be saved, and on the other hand, a temperature gradient is formed between the drying hoppers in each layer. Avoid the problem of grain damage and uneven drying caused by direct drying with higher temperature hot air when the grain humidity is high; secondly, although the air used up in the lower layer has a certain humidity, it must be lower than the humidity that can be produced by the upper layer of grain, so It does not affect the drying of the upper grain.
