Hot air circulation equipment and tobacco leaf baking system

The invention relates to the technical field of hot air circulation, in particular to hot air circulation equipment which comprises a tobacco leaf baking room, and the side surface of the tobacco leaf baking room is fixedly connected with a base of the hot air circulation equipment. The hot air circulation equipment and the tobacco leaf baking system have the beneficial effects that the end of a shifting block is fixedly connected with the surface of a rubber baffle, so that the rubber baffle is conveniently shifted by the shifting block to rotate in a movable groove; therefore, the circulation efficiency of the fan for conveying the airflow into the hot air circulation equipment is adjusted by changing the air circulation rate in the air inlet pipe, and the hot air circulation equipment can be controlled to circularly convey the hot airflow in the tobacco leaf baking room according to needs. And when the rubber baffle is rotated on the inner wall of the movable groove, dust on the surface of the rubber baffl
