[0027] Working principle: When the utility model is in use, food materials are put into the material holding and uniform air flow mechanism 2, and then the air intake fan 9 and the heating device 11 are started. After the air is heated by the heating device 11, it is drawn in by the air intake fan 9 and discharged into the frame 1 through the air intake pipe 8. The hot air spirally rises and disperses in the frame 1. Most of the hot air enters the material holding and uniform air flow mechanism 2 through the uniform air holes 25 on the upper straight end 21 and the surface of the lower vertebral body 22, and then disperses from the periphery, penetrates the material from the periphery of the material pile, and dries the food materials.

While drying, the material enters the feed pipe 132 through the discharge pipe 131, and the drive motor 134 is started to drive the auger 133 to rotate, driving the food material into the feed hopper of the elevator 12, and then as the elevator 12 is lifted, it is discharged into the material holding and uniform air flow mechanism 2 again, so that the material at the bottom will be spread on the top again, thereby achieving the effect of turning the food material. The number of times and time of turning the material during the entire drying process can be executed by the PLC according to the preset program.
