Description

Technical Field

[0001] The present invention relates to the field of drying technology, and more specifically to a drying device for forming medicine particles. Background Art

[0002] In the pharmaceutical production process, the drying process after particle formation is crucial. Most traditional drying devices spread out the formed pharmaceutical particles and convey and dry them through a conveyor. However, this method has exposed some obvious problems in practical applications, especially the phenomenon that pharmaceutical particles are easy to stick together and stack after forming, which brings considerable challenges to the drying process.

[0003] Existing pharmaceutical granule forming and drying devices usually consist of a conveyor, a drying box, and a heat source. The formed pharmaceutical granules are evenly spread on the conveyor belt, and as the conveyor belt moves, the granules enter the drying box. A heat source is provided in the drying box, which transfers heat to the pharmaceutical granules by heating the air or hot air, evaporating the moisture therein, thereby achieving the purpose of drying.

[0004] During the molding process, pharmaceutical particles often stick together due to factors such as surface tension, humidity or additives. This adhesion not only affects the dispersibility of the particles, but may also cause the particles to stack during transportation and drying.

[0005] When drying stacked particles, it is easy to have problems with incomplete drying because the internal moisture is difficult to evaporate completely. At the same time, the stacked parts may have uneven drying effects due to uneven heating, affecting the quality of the final product. Traditional drying equipment often cannot ensure that all particles are evenly heated, which also leads to reduced drying efficiency. Uneven drying may also cause some particles to be over-dried and lose their efficacy, or some particles to be under-dried and contain too much moisture, further affecting the quality and stability of the product.

[0006] In summary, the existing drug particle forming and drying devices face many challenges in application, and need to continuously innovate and improve technology to improve drying efficiency and quality and ensure the stability and safety of drugs. In view of this, we propose a drug particle forming and drying device. Summary of the invention

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] 1. The present invention improves the structure of the existing drying device for forming pharmaceutical particles, arranges a driving mechanism on a frame, and rotatably arranges a drying drum on the driving mechanism so that the drying drum can rotate on the driving mechanism, arranges a feeding part at one end of the drying drum, and arranges a discharging part at the other end of the drying drum, and arranges a heating mechanism at a position of the frame close to the feeding part.

[0022] 2. When the drying state is required, insert the paddle into a slot away from the reduction motor so that the plug block at one end is plugged into the engagement slot on the inner turntable. At this time, the reduction motor is driven to drive the rotating shaft to rotate, and the rotating shaft drives the inner turntable to rotate synchronously. Since a chain rod is connected between the two sleeves, and the chain rod is inserted into the sleeve, the sleeve, the support frame, the outer ring and the inner tooth groove are synchronously driven to rotate. At this time, since the rotation speed of the inner tooth groove is consistent with that of the outer tooth groove, there is no differential speed, and the gear assembly is stationary. At this time, it makes an overall revolution. Since the outer wall of the outer ring is connected to the inner wall of the drying cylinder, the drying cylinder is driven to rotate, thereby realizing rotary drying of the material. The method of rotary drying of pharmaceutical particles of the present invention has high uniformity, and greatly reduces the problem of large differences in moisture content of pharmaceutical drying.

[0023] 3. When the present invention needs to be in a whipping state, the paddle is inserted into a slot close to the reduction motor, so that the plug block at one end is plugged into the fixed block and the fixed slot, so that the sleeve, the sleeve support frame, the outer ring and the inner tooth groove are fixed. At this time, the reduction motor is driven to drive the rotating shaft to rotate, and the rotating shaft drives the inner turntable to rotate synchronously. The outer tooth groove of the inner turntable engages to drive the gear assembly to rotate, so that the gear assembly rotates in a circular arc along the inner tooth groove of the inner wall of the outer ring, and the gear assembly drives the whipping assembly to rotate in the drying cylinder to whip the clustered drug particles, thereby further improving the drying efficiency.

[0024] 4. When it is necessary to adjust the unfolded size of the cluster dispersion mechanism of the present invention, the slide rod is first driven to slide on the slide groove by the paddle, and the paddle is inserted into the slot in the middle so that the plug blocks at both ends are not connected to the locking groove and the fixing groove. At this time, the reduction motor is driven to drive the rotating shaft rod to rotate, and the rotating shaft rod drives the inner turntable, the outer tooth groove and the sleeve disc to rotate. Since a chain rod is connected between the two sleeve discs, and the chain rod is inserted on the sleeve, the sleeve, the support frame, the outer ring and the inner tooth groove are synchronously driven to rotate. The outer tooth groove and the inner tooth groove both rotate. Since the sizes of the outer tooth groove and the inner tooth groove are different, a differential speed is generated, so that the gear assembly of the cluster dispersion mechanism rotates to adjust the size of the whipping assembly, so as to adjust the size of the cluster dispersion mechanism to adapt to medicines of different particle sizes, so as to improve the efficiency of crushing cluster medicine particles.
