The temperature of the multi-layer hot air inlet pipe can be reduced step by step, so that the temperature of the material tends to room temperature when it is finally discharged, effectively avoiding the problem of material rehumidification caused by excessively high discharge temperature in traditional drying equipment, and further ensuring product quality.
