The drug intermediate crystals crushed by the crushing mechanism 4 fall on the upper surface of the vibrating screen 502, and the drug intermediate crystals smaller than the aperture of the vibrating screen 502 pass through the vibrating screen 502, fall to the bottom of the tank body 1, and are discharged from the discharge pipe 102. A container can be placed directly below the discharge pipe 102 to catch the drug intermediate crystals that have been screened, while the drug intermediate crystals larger than the aperture of the vibrating screen 502 are still located on the upper surface of the vibrating screen 502, and slide down toward the tank door 504 as the vibrating screen 502 is inclined.

[0023] See also Figure 2-3 One end of the guide plate 503 is located inside the tank body 1, and the other end of the guide plate 503 is located outside the tank body 1. The guide plate 503 passes through the tank body 1. The guide plate 503 is located below the vibration screen 502. The upper wall of the guide plate 503 is in contact with the lower wall of the vibration screen 502. The tank door 504 is hinged to the tank body 1.

One side of the vibration screen 502 is in contact with the tank door 504. When a batch of drug intermediate crystals are dried, crushed and screened, the tank door 504 can be opened, so that unqualified drug intermediate crystals slide from the vibrating screen 502 to the guide plate 503, and are discharged from the inside of the tank body 1 to the outside of the tank body 1. A container can be placed under the guide plate 503 to catch the unqualified drug intermediate crystals. After the discharge is completed, the unqualified drug intermediate crystals in the container can be put into the inside of the tank body 1 again from the feed hopper 101.

[0024] When implementing, follow these steps:

[0025] 1) First, the drug intermediate crystals are put into the tank body 1 from the feed hopper 101;

[0026] 2) Then the drug intermediate crystals are dried by the electric heating wire 2 and the electric heating fan 3;

[0027] 3) crushed by crushing mechanism 4;

[0028] 4) Then, after being screened by the circulating screening mechanism 5, the qualified drug intermediate crystals are discharged from the discharge pipe 102;

[0029] 5) Unqualified drug intermediate crystals slide from the vibrating screen 502 to the guide plate 503 and are discharged to the outside of the tank body 1;
