Vertical rotary drying device for grain particles

Abstract

The invention discloses a vertical rotary drying device for grain particles. The vertical rotary drying device comprises a plurality of rotary trays. The inner diameters of the multiple rotary trays are sequentially increased from top to bottom. A vertical rotary shaft is integrally arranged at the center positions of the multiple rotary trays in a through manner and divided into a plurality of equal-height shaft joints by the multiple rotary trays, and a transition transfer mechanism is further arranged between each shaft joint and the corresponding rotary tray. A heating layer is arranged at the bottom of each rotary tray. The bottom of the vertical rotary shaft is arranged in a bearing, and a rotary block is further arranged on the vertical rotary shaft. The bearing is arranged on a base. A motor in transmission connection with the rotary block is arranged on the base. A feeding mechanism is further arranged above the uppermost rotary tray. A dryer of the vertical rotary drying device is simple in structure,; the application range is wide; the vertical rotary drying device is suitable for airing in rainy days and suitable for airing in sunny days; the airing efficiency is high; the heating effect is good; the grain particle dryness is uniform; and the mould phenomenon caused by the fact that drying is not achieved in time is avoided.

Description

technical field [0001] The invention relates to the field of agricultural and forestry equipment, in particular to a vertical rotary drying device for grain particles. Background technique [0002] After the grain grains are harvested in the harvest season, in order to ensure their long-term storage without mold, they need to be dried naturally, and the disadvantage of natural drying is that they need to meet better sunny days during the grain harvest. Grain grains can be aired in time, but if it rains during the harvest season, it will be difficult to dry the grains, and if the freshly harvested grains are not dried in time on rainy days, it will cause a lot of damage. Grain grains are damaged and spoiled by mold. [0003] And for existing this airing mode not only can only adapt to the change of weather and airing, has more uncertain factors, and the efficient of airing is low, and labor intensity is big, and the dryness of airing is uneven.
