step one, in a preheating stage, air is introduced into an air guide pipe (3322) by a fan (3321), the air is heated when passing through a preheating device (331), a central processing unit (5) adjusts the air quantity entering a preheating chamber (3) through a control valve (7), the heated air enters the preheating chamber (3), after all the garbage is thrown onto a first conveying assembly (34) through a feed hopper (32), the first conveying assembly (34) stops conveying, the garbage is continuously and uniformly vibrated and stir-fried by a vibrating device (9), the heated air at 40-45 ℃ is preheated, when a first humidity sensor (35) detects that the humidity content in the preheating chamber (3) reaches a set value, the central processing unit (5) opens a feeding port (6), the first conveying assembly (34) starts conveying the garbage, and the step two is executed;
step two, in the drying stage, after the preheated garbage is completely conveyed to a second conveying assembly (43) in the drying chamber (4) from the feeding port (6) through a first conveying assembly (34), the feeding port (6) is closed, the second conveying assembly (43) stops conveying, the garbage is continuously and uniformly vibrated and stir-fried by a vibrating device (9), meanwhile, the drying treatment at 145-150 ℃ is carried out again by an infrared heating device (42), and when the second humidity sensor (44) detects that the humidity content in the drying chamber (4) reaches a set value, the second conveying assembly (43) conveys the garbage to a discharging hopper (41);
step three, fault detection is carried out, after the central processing unit (5) receives temperature data in the preheating chamber (3) and the drying chamber (4) through the temperature sensor (10), if sudden parameter increase or sudden parameter decrease occurs, the central processing unit (5) automatically stops the whole machine to work, and fault maintenance is carried out; and returning to the step one after the fault is eliminated.
