Drying system

The utility model discloses a drying system which comprises a feeding device and a rotational flow bed, the rotational flow bed comprises a barrel body with the cross section similar to a circle, thefeeding device is communicated with the barrel body in the tangential direction of the barrel body, and a plurality of air blowing pipes are communicated with the side, opposite to the feeding device,of the barrel body. In the utility model, the side, opposite to the feeding equipment, of the rotational flow bed is a ventilation blind area, the problem of material accumulation exists, and seriousinfluence is caused to normal production, so that the air blowing pipe is arranged in the ventilation blind area, small-particle materials can be blown away from the ventilation blind area, and the materials are prevented from being accumulated. 本实用新型公开一种干燥系统，包括供料设备和旋流床，旋流床包括横截面为类圆形的桶体，所述的供料设备沿桶体切线方向连通所述桶体，所述桶体上与所述供料设备相对的一侧连通有若干吹气管；本实用中，旋流床上与供料设备相对的一侧为通风盲区，存在积料问题，对正常生产造成严重影响，因此在该通风盲区设置吹气管，可将小颗粒物料吹离通风盲区，防止了物料堆积。
