Airflow drying equipment

The invention discloses airflow drying equipment. The airflow drying equipment comprises a long-strip-shaped drying channel, and a conveying line is arranged in the drying channel along the axis; theairflow drying equipment further comprises an air supply assembly and an exhaust assembly, wherein the air supply assembly is used for conveying air into the drying channel, and the exhaust assembly is used for exhausting the air from the drying channel; the drying channel sequentially comprises a heating area, a drying area and a cooling area from a feeding port to a discharging port, the heatingarea and the drying area as well as the drying area and the cooling area are correspondingly separated by partition boards, and a conveying line penetrates through the partition boards; a plurality of heating mechanisms are both arranged in the heating area, the drying area and the cooling area along the axis; and each heating mechanism is configured that the temperature of the heating area is gradually increased in the material conveying direction from the feeding port to the discharging port, the temperature of the drying area is constant, and the temperature of the cooling area is gradually reduced. According to the airflow drying equipment, slow heating and slow cooling of a heating process and a cooling process before and after the drying are realized, so that the negative effects caused by sharp changes of the temperature can be reduced or even avoided.
