Environmental box drying device

The utility model discloses an environmental box drying device. The environmental box drying device comprises a first drying mode and a second drying mode. In the first drying mode, after compressed air is dried through the first drying cylinder, the drying agent in the second drying cylinder is dried through the dried compressed air, and drying regeneration treatment of the drying agent in the second drying cylinder is achieved; in the second drying mode, after the compressed air is dried through the second drying cylinder, the drying agent in the first drying cylinder is dried through the dried compressed air, and drying regeneration treatment of the drying agent in the first drying cylinder is achieved; by switching the first drying mode and the second drying mode, the drying agent in the first drying cylinder and the second drying cylinder is recycled, so that the effect that the dryer works continuously and stably is achieved. 本实用新型公开了一种环境箱干燥装置，包括第一干燥模式和第二干燥模式；第一干燥模式，压缩空气经过第一干燥筒干燥之后，利用干燥的压缩空气对第二干燥筒内的干燥剂进
