Here, the mutually independent may include at least that the drying air duct is mutually independent, the heating mode is mutually independent, and the exhaust structure is mutually independent.

In the embodiment of the disclosure, two sets of independent drying air paths can be arranged in the drying equipment, so that the drying equipment is suitable for different drying requirements.

Other embodiments of the disclosure will be apparent to those skilled in the art from consideration of the specification and practice of the disclosure disclosed herein. This disclosure is intended to cover any adaptations, uses, or adaptations of the disclosure following the general principles of the disclosure and including such departures from the present disclosure as come within known or customary practice within the art to which the disclosure pertains. It is intended that the specification and examples be considered as exemplary only, with a true scope and spirit of the disclosure being indicated by the following claims.

It is to be understood that the present disclosure is not limited to the precise arrangements and instrumentalities shown in the drawings, and that various modifications and changes may be effected without departing from the scope thereof. The scope of the present disclosure is limited only by the appended claims.
