The drying box body is provided with a conveying through hole. One end of the drying conveyor belt movably penetrates through the conveying through hole. The drug feeding hopper is located on one side of the drying box body and above the drying conveyor belt. Blowing and drying components are installed on the top side and the bottom side of the drying box body respectively, and the two blowing and drying components are arranged in a staggered manner.

The conveying component 1 includes a driving part 101, a frame 102 and a conveyor belt 103. The transfer bin is composed of a wire drawer 6 and two sets of splicing seats 5 fixedly connected. One of the two sets of splicing seats 5 is fixedly connected to the conveyor belt 103. A connecting seat 3 is fixedly connected to the outer surface wall of the frame 102. An outer cover 2 is fixedly connected between the connecting seat 3 and the frame 102. An upper bin 12 and a lower bin 13 are respectively fixedly connected to the inner surface walls of the outer cover 2 and the connecting seat 3. Spray nozzles 14 are integrated on the opposite surfaces of the upper bin 12 and the lower bin 13. And a heating component for supplying hot air flow to the upper bin 12 and the lower bin 13 is integrated on the outer surface wall of the outer cover 2.

[0025] The transfer bin is composed of a splicing seat 5 and a wire drawer 6. Multiple transfer bins are arranged progressively along the extending direction of the conveyor belt 103. The solid particle medicaments inside the external blanking bin are quantitatively dropped into the transfer bin. This part is the prior art and will not be elaborated here. The driving force is provided for the transfer bin through the conveying component 1. The cooperation between the sliding sleeve 7 and the sliding rail 8 ensures the stable operation of the transfer bin. The hot air flow generated by the heating pipes inside the heating bin 9 is introduced into two sets of branch pipes 11 through a pump body 10, and then transferred to the upper bin 12 and the lower bin 13 respectively through the two sets of branch pipes 11. The spray nozzles 14 on the upper bin 12 and the lower bin 13 introduce the hot air flow into the transfer bin from both sides of the vertical end. While ensuring the uniformity of the contact between the solid particle medicaments and the hot air flow, the overall operation stability of the equipment is improved.

[0026] Specifically, as Figure 2 shown in Figure 4 As shown, connecting pieces 15 are fixedly connected to the open ends of both the upper bin 12 and the lower bin 13. And the two sets of connecting pieces 15 are respectively fixedly connected to the inner surface walls of the outer cover 2 and the frame 102 through two sets of locking rods.

[0027] Specifically, as Figure 2 shown in Figure 3As shown, the frame 102 is fixedly connected to the connecting seat 3 through the cross base 4. A support frame is fixedly connected to the bottom of the cross base 4.
