The hot air generating component is connected to the hot air circulation channel, and the products or materials are conveyed one by one into the furnace body through the conveyor belt for drying and dehumidification; in the actual application of this hot air circulation tunnel furnace, the conveyor belt is used to transport the LED package reel or other sheet products to the inside of the furnace body for heating, drying and dehumidification, and then the conveyor belt directly transports the LED package reel or other sheet products to the next processing station for processing. The conveyor belt not only has low transportation efficiency, but also causes the LED package reel or other sheet products to be heated unevenly on all sides, resulting in poor drying effect, which in turn leads to extended drying and dehumidification time and reduced drying efficiency. At the same time, it also causes the conveyor line to be too long and increases the overall footprint of the equipment.
