[0014] A Chinese medicine granule drying device and drying method, comprising the following steps: S1. Pre-drying: pour the Chinese medicine particles to be dried into the pre-drying shell through the feed port, and the Chinese medicine particles slide downward through the pre-drying shell. The hot air used in the shell flows into the pre-drying shell through the auxiliary shell and the connecting hole, taking away the moisture inside the Chinese medicine particles. The Chinese medicine particles are continuously pre-dried, which improves the efficiency of hot air utilization. The Chinese medicine particles slide into the fixed cylinder through the conduit; S2, crushing: the Chinese medicine particles slide into the inner drying cylinder through the guide groove. After the Chinese medicine particles in the inner drying cylinder are pre-dried, air is blown into the fixed cylinder, and the heating plate is powered on. The temperature of the heating plate rises, and the air entering the fixed cylinder is heated. The hot air enters the inner drying cylinder through the drying hole, and the Chinese medicine particles are continuously dried.

[0015] It can be seen from the above that the Chinese medicine granule drying device and drying method provided by the present invention have the following technical effects.

[0016] First, the internal drying cylinder rotates at a high speed, which continuously drives the Chinese medicine particles inside the internal drying cylinder to hit the baffle rod, breaking the Chinese medicine particles inside the internal drying cylinder. The crushed Chinese medicine particles slide into the outer drying cylinder through the discharge chute. Due to the height difference between the two ends of the fixed cylinder, the Chinese medicine particles inside the outer drying cylinder continuously slide toward the discharge chute. At this time, hot air is discharged into the interior of the outer shell through the flow hole to perform secondary drying on the Chinese medicine particles, which has the effect of reducing the adhesion of the Chinese medicine particles when drying them.

[0017] Second: The Chinese medicine particles slide into the interior of the fixed cylinder through the conduit, and then slide into the interior of the inner drying cylinder through the guide groove. The motor is started, and the motor rotation drives the main gear to rotate, and the main gear drives the outer gear, inner gear and intermediate gear to rotate. The speed of the outer cylinder and the outer drying cylinder is low, and the speed of the inner cylinder and the inner drying cylinder is high. After the Chinese medicine particles inside the inner drying cylinder are pre-dried, the particle separation degree is improved.

[0018] Third: the dried Chinese medicine particles enter the inside of the discharge shell through the discharge chute, and the hot air after use inside the outer shell enters the inside of the installation shell to dry the Chinese medicine particles. After long-term use, the Chinese medicine particles will block the processing hole. During the rotation of the outer drying cylinder, the linkage block is driven to rotate continuously, so that the linkage block continuously squeezes the top of the rotating plate, driving the rotating plate to rotate, and the rotating plate drives the moving sleeve to reciprocate back and forth through the connecting plate, thereby driving the cleaning plate to reciprocate back and forth, and the movement of the cleaning plate will crush the Chinese medicine particles entering the processing hole, thereby playing the effect of cleaning the Chinese medicine particles inside the processing hole.

8. The Chinese medicine granule drying device according to claim 7, characterized in that: The cleaning mechanism comprises a linkage block (37) fixedly connected to one end of the inner drying cylinder (25); a rotating plate (44) is rotatably connected to an inner wall of one side of the outer shell (1) near the linkage block (37); a connecting plate (43) is rotatably connected to the bottom end of the rotating plate (44); and a moving sleeve (42) is fixedly connected to one end of the connecting plate (43).

9. A Chinese medicine granule drying device according to claim 8, characterized in that: The bottom of the discharge shell (27) is fixedly connected to two slide rails (45), one side of the slide rail (45) is slidably connected to a cleaning plate (40), a surface of the cleaning plate (40) is provided with a plurality of spacing grooves (46), the bottom of the cleaning plate (40) is fixedly connected to a connecting frame (41), and the connecting frame (41) is movably connected to the moving sleeve (42).

10. The drying method of the Chinese medicine granule drying device according to claim 9, comprising the following steps: S1, pre-drying: the Chinese medicine particles to be dried are poured into the interior of the pre-drying shell (18) through the feed port (4), the Chinese medicine particles slide downward through the interior of the pre-drying shell (18), and the hot air used in the interior of the outer shell (1) flows into the interior of the pre-drying shell (18) through the auxiliary shell (17) and the connecting hole (20), taking away the moisture inside the Chinese medicine particles, and continuously pre-drying the Chinese medicine particles, thereby improving the efficiency of hot air utilization. The Chinese medicine particles slide into the interior of the fixed cylinder (14) through the conduit (2); S2, crushing: the Chinese medicine particles slide into the interior of the inner drying cylinder (25) through the guide groove (30). After the Chinese medicine particles in the inner drying cylinder (25) are pre-dried, air is blown into the interior of the fixed cylinder (14), and the heating plate (32) is powered. The temperature of the heating plate (32) rises, and the air entering the fixed cylinder (14) is heated. The hot air enters the interior of the inner drying cylinder (25) through the drying hole (39), and the Chinese medicine particles are continuously dried. The blocking rod (26) crushes the Chinese medicine particles in the inner drying cylinder (25). The crushed Chinese medicine particles slide into the interior of the outer drying cylinder (24) through the discharge groove (22). Due to the height difference between the two ends of the fixed cylinder (14), the Chinese medicine particles in the outer drying cylinder (24) continuously slide toward the discharge groove (38). At this time, the hot air is discharged into the interior of the outer shell (1) through the flow hole (23); S3, re-drying: the dried Chinese medicinal particles enter the interior of the discharge shell (27) through the discharge trough (38), and the hot air used inside the outer shell (1) enters the interior of the installation shell (28) to dry the Chinese medicinal particles; S4, cleaning: After long-term use, the Chinese medicine particles will clog the processing holes (29). During the rotation of the outer drying cylinder (24), the rotating plate (44) drives the moving sleeve (42) to reciprocate forward and backward through the connecting plate (43), thereby driving the cleaning plate (40) to reciprocate forward and backward. The movement of the cleaning plate (40) crushes the Chinese medicine particles entering the processing holes (29), thereby achieving the effect of cleaning the Chinese medicine particles inside the processing holes (29). The Chinese medicine particles enter the interior of the mounting shell (28) through the multiple processing holes (29), slide inside the mounting shell (28), and are finally discharged through the discharge port (8).
