[0024] When processing, the feed additive raw material particles are poured into the feeding tank 13 through the feeding funnel 131, and directly fall into the inner cavity of the stainless steel mesh barrel 11, then the whole hot air blower mechanism 3 is started, after being powered on, the external cold air is blown into the heater 31 by the air blower 32, the heater 31 is provided with a spiral electric heating wire, the cold air uniformly passes through the inside and outside of the electric heating wire, and the heat generated by the electric heating wire after being powered on exchanges heat with the passing cold air, so that the temperature of the hot air at the hot air pipe 33 is increased; the K-type thermocouple is installed at the hot air pipe 33, which is used for real-time monitoring of the outlet air temperature; the K-type thermocouple converts the detected temperature change into an electric signal and feeds back to the temperature controller 34 in time.

[0025] As shown in Figure 4 The discharge mechanism 5 includes a discharge pipe 51, the top end of the discharge pipe 51 is fixedly connected with the bottom center of the mixed drying tank body 1 and penetrates into the inner cavity of the discharge hopper 14, a servo motor two 52 is fixedly installed at the bottom of the discharge pipe 51, the output shaft of the servo motor two 52 penetrates into the inner cavity of the discharge pipe 51 and is fixedly installed with a discharge screw rod 53, and a discharge inclined pipe 54 penetrating through the inner cavity of the discharge pipe 51 is fixedly installed at the front side of the discharge pipe 51.

The unqualified feed additive raw material particles are left on the screen plate 64, and the vibration is transmitted from the mounting frame 61 to the screening frame 63 through the vibration motor 67, so that the screening of the screen plate 64 is more efficient. The unqualified size feed additive raw material particles in the screening frame 63 can be rotated out by rotating the rotating clamping rod 66 clamped between the rear side of the vertical portion of the L-shaped limiting plate 65 and the front side of the screening frame 63, so that the screening frame 63 can be directly pulled out through the top of the limiting plate 62, facilitating recycling and processing.
