[0032] Please see Figure 1 , Figure 2 and Figure 3 This embodiment provides a technical solution: a multi-layer flat plate drying device for raw pharmaceutical granules, comprising a base 1, a discharge section 2, a drying section 3, and a feeding section 4.
[0033] The discharge section 2 is located on top of the base 1. The discharge section 2 has a bottom shell 201 on top of the base 1, with a discharge port 204 at the bottom. Several drying sections 3 are stacked on top of the discharge section 2. Each drying section 3 has a connecting shell 301 on top of the bottom shell 201. A conveyor belt 303 is horizontally arranged inside the connecting shell 301. A motor 304 is located on the side of the connecting shell 301, and its output is connected to the conveyor belt 303. Specifically, the motor 304 is a servo motor. The working principle of the servo motor is mainly based on a closed-loop control system. Its core is to precisely control the position, speed, and acceleration of an object. Taking pulse control as an example, after receiving a pulse signal, the servo motor will rotate by an angle corresponding to the pulse, thereby achieving displacement. Simultaneously, the encoder inside the motor 304 will emit a corresponding number of pulses as feedback, forming a closed loop with the pulses sent by the control circuit. The control circuit continuously adjusts the operation of the motor 304 according to these pulse signals until it reaches and maintains the set position or speed. The above is the prior art and will not be repeated below. When selecting a model, its power should be selected to match the needs of the device to ensure that the object to be driven is driven. The heating block 309 is provided inside the connecting shell 301. The heating block 309 is located inside the conveyor belt 303. The side of the connecting shell 301 is provided with a connecting structure and connected to the bottom shell 201. The feeding part 4 is located on the top of the drying part 3. The feeding part 4 has a top shell 401 located on the top of the drying part 3. The top of the top shell 401 is provided with a feeding hopper 402 for feeding. The number of drying parts 3 can be adjusted according to actual needs to realize multi-layer drying operation of raw drug particles. The raw drug particles enter from the feeding hopper 402, are conveyed by the conveyor belts 303 of multiple drying parts 3, are dried under the action of the heating block 309, and finally discharged from the discharge port 204. The multi-layer drying parts 3 can increase the drying time and effect and improve the drying efficiency.
[0034] Example 2
[0035] Please see Figure 4 , Figure 5 and Figure 6 This embodiment provides a technical solution: a multi-layer flat plate drying device for raw pharmaceutical granules, comprising a discharge section 2, a drying section 3, and a feeding section 4.
[0036] A groove a202 is provided on the top of the bottom shell 201, and a rubber pad is provided in the groove a202. A protrusion a306 is provided on the bottom of the connecting shell 301. The protrusion a306 is embedded in the groove a202 and connected to the bottom shell 201. A connecting buckle a203 is provided on the side of the bottom shell 201.

This can make the connection between the bottom shell 201 of the discharge section 2 and the connecting shell 301 of the drying section 3 tighter and more stable. The rubber pad in the groove a202 can play a role in buffering and sealing.
[0037] An intake fan 205 is provided at the bottom of the bottom shell 201, and an exhaust fan 404 is provided at the top of the top shell 401, which can form an air flow circulation. The intake fan 205 draws in air from the bottom, and when it passes through the drying section 3, it carries away the water vapor and heat generated during the drying process of the raw material granules. Then, it is discharged from the top through the exhaust fan 404. This can speed up the drying process and improve the drying effect.
[0038] A connecting buckle b307 is provided on the top of the connecting shell 301. Another connecting block a308 is embedded in the connecting buckle b307 and connected to the connecting buckle b307 by bolts, which can facilitate the stacking connection between multiple drying sections 3. The connection between the connecting buckle b307 and the connecting block a308 by bolts can ensure a firm connection between adjacent drying sections 3, guarantee the overall stability of the device. At the same time, this connection method is also easy to install and disassemble, and facilitates the maintenance and cleaning of the drying sections 3.
[0039] A groove b305 is provided on the top of the connecting shell 301, and a rubber gasket is provided inside the groove b305.

[0040] Connecting vents 302 are provided on both sides inside the connecting shell 301. The connecting vents 302 are located next to the conveyor belt 303, which can allow air to circulate better inside the drying section 3.
[0041] A connecting block b405 is provided at the bottom of the top shell 401. The connecting block b405 is embedded in the connecting buckle b307 and connected to the connecting buckle b307 by bolts, so that the top shell 401 of the feeding part 4 can be firmly connected to the connecting shell 301 of the drying part 3.
[0042] The feeding section 4 also has a distribution plate 403 neatly arranged inside the feeding hopper 402, which can make the raw material particles entering from the feeding hopper 402 more evenly distributed on the conveyor belt 303.
[0043] Working principle: First, start the device by turning on the motor 304, heating block 309, intake fan 205, and exhaust fan 404. The motor 304 drives the conveyor belt 303 to start running, the heating block 309 begins to heat up, the intake fan 205 draws in air from the bottom, and the exhaust fan 404 exhausts air from the top, forming an airflow circulation. Then, the raw material drug granules are poured into the feed hopper 402. The neatly arranged distribution plates 403 in the feed hopper 402 disperse the concentrated raw material drug granules, making the raw material drug granules more uniform. The raw drug particles are distributed on the conveyor belt 303 in the uppermost drying section 3. The conveyor belt 303 then moves the raw drug particles forward. During the movement, the raw drug particles come into full contact with the heat generated by the heating block 309, and drying begins. At the same time, the air drawn in by the suction fan 205 circulates evenly inside the drying section 3 through the ventilation port 302, carrying away the moisture and heat generated during the drying process of the raw drug particles. This air carrying moisture and heat is then discharged from the top through the exhaust fan 404. When the raw drug particles move to this layer of the drying section with the conveyor belt 303... After the end of step 3, the raw material granules will fall onto the conveyor belt 303 of the next drying section 3, repeating the above drying process. Due to the setting of several stacked drying sections 3, the raw material granules will pass through multiple layers of drying in sequence, increasing the drying time and effect. Finally, the raw material granules after multiple layers of drying will fall from the bottom drying section 3 into the bottom shell 201 of the discharge section 2, and finally be discharged from the discharge port 204 at the bottom of the bottom shell 201, completing the entire drying operation. Moreover, the bottom shell 201 of the discharge section 2 and the connecting shell 301 of the drying section 3 are connected by a protrusion a306 embedded in a groove. A202 and connecting block A308 are embedded in connecting buckle A203 and bolted together. Adjacent drying sections 3 are connected by protrusion A306 embedded in groove B305 and connecting block A308 embedded in connecting buckle B307 and bolted together. The top shell 401 of the feeding section 4 and the connecting shell 301 of the drying section 3 are connected by connecting block B405 embedded in connecting buckle B307 and bolted together. This ensures that the connections of each part of the device are tight and stable. The rubber pads in groove A202 and groove B305 play a buffering and sealing role, reducing heat loss and external dust entry.
