Drying equipment

The invention discloses drying equipment. The drying equipment comprises a drying box, a cold dryer and an induced draft fan; the cold dryer and the induced draft fan are respectively arranged at bothends of the drying box; and an air inlet of the induced draft fan and an air outlet of the cold dryer are both connected to the drying box. The cold dryer can generate dry air, when the induced draftfan is started, the air is extracted from the drying box and discharged through the air outlet, so that the negative pressure is generated in the drying box, and the dry cold air generated by the cold dryer is sucked into the drying box, and the dry air contacts materials in the drying box and exchanges moisture. Since the water vapor component in the dry air is close to zero and has the functionof vacuum dehumidification, moisture can be quickly absorbed from the materials that need to be dried to achieve rapid drying of the materials. 本发明公开了一种干燥设备，包括干燥箱、冷干机和引风机，冷干机和引风机分别设在干燥箱的两端，且引风机的进气口和冷干机的出气口均连通干燥箱，利用冷干机能够产生干燥空气，
