[0002] The pill making process includes preparing raw materials, grinding and mixing, processing into pills, drying and packaging. According to the pill formula, the medicinal materials are ground into powder and mixed evenly, and then a binder or lubricant is added to make pills, which are then dried, solidified and packaged. The entire process needs to be carried out strictly in accordance with the formula and operating procedures to ensure the quality and hygienic safety of the pills.

[0003] In the process of making pills, they often need to go through a shot blasting machine. The shot blasting machine rotates and rubs the pills to make them roll and project continuously in the machine, so that the pills form a more rounded shape, ensuring the beautiful appearance and stable quality of the pills. After passing through the shot blasting machine, they need to be dried. The pills may contain moisture or volatile components. If the pills are stored in a humid environment, they may absorb moisture, deform or lose their efficacy. By drying, the moisture content in the pills can be reduced, and the stability and shelf life of the pills can be improved. In addition, drying also helps to maintain the shape and appearance of the pills, and improve the quality and appearance of the pills. In the process of making pills, some ingredients may need to be solidified or crystallized under dry conditions to ensure the stability and efficacy of the pills.

DETAILED DESCRIPTION

[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] Example 1

[0019] refer to Figures 1 to 5 A pill drying device comprises a box body 1 and a hot air conveying unit 2, wherein the hot air conveying unit 2 is connected to the bottom of the box body 1, and a feeding pipe 11 and a discharging pipe 12 are respectively arranged at both ends of the box body 1, and a horizontally arranged conveying plate 13 is arranged in the box body 1, and a plurality of protrusions 131 protruding along the surface of the conveying plate 13 are arranged on the side of the protrusion 131, and a channel 1313 penetrating the bottom of the conveying plate 13 is arranged, and the bottom of the conveying plate 13 is the input end of the channel 1313, and the side of the protrusion 131 is the output end of the channel 1313, and the direction facing the output end of the channel 1313 is the conveying direction of the conveying plate 13.

[0020] It should be noted here that before using the pill drying device, it is necessary to pass through the shot blasting machine first, that is, the feed pipe 11 on the box body 1 is connected to the shot blasting machine. After the pills are processed by the shot blasting machine, the appearance of the pills is more uniform and enters the conveying plate 13. The hot air conveying unit 2 passes the hot air into the box body 1, and passes through the channel 1313 from the bottom of the conveying plate 13 and is output from the side of the convex portion 131. Because the output position is the side of the convex portion 131, the hot air is output horizontally at the convex portion 131. The horizontally output hot air will provide power to the pills, so that the pills can roll in the length direction of the conveying plate 13, that is, the pills are moving relative to the conveying plate 13 until they roll to the discharge pipe 12 for discharge, so that the drying is more complete and the stability of the pills after drying is better.

[0021] In this embodiment, the convex portion 131 includes a first bump 1311, which is arranged in an array along the length direction of the conveying plate 13, and the output end of the channel 1313 is located on the side of the first bump 1311, and the first bump 1311 is a hemispherical crown structure.

[0022] Because the pills are likely to collide with the first bump 1311 during transportation, in order to avoid damage to the pills during collision, the first bump 1311 is set to a hemispherical crown state, that is, half of the normal spherical crown is vertically cut off, so that one side of the first bump 1311 is an arc surface, and the vertical surface in the other side surface. Because the pills will not move in the opposite direction during transportation, only the back side of the arc surface needs to be transported.

[0023] As a further optimization of this embodiment, the convex portion 131 also includes a second convex block 1312, and the structure of the second convex block 1312 is exactly the same as that of the first convex block 1311; along the conveying direction of the conveying plate 13, the first convex blocks 1311 and the second convex blocks 1312 are alternately arranged; in the vertical plane projection along the conveying direction of the conveying plate 13, the second convex block 1312 is located between the two first convex blocks 1311.

[0024] We found that although conveying can be achieved if only the first protrusions 1311 are used, since the first protrusions 1311 are arranged in an array, there will be intervals between the first protrusions 1311 along the length direction of the conveying plate 13, and the smoothness of the pills moving in this interval is poor. Therefore, in order to further optimize the conveying smoothness of the conveying plate 13, a second protrusion 1312 that is exactly the same as the first protrusion 1311 is added, and in the conveying direction of the conveying plate 13, the first protrusion 1311 and the second protrusion 1312 are alternately arranged; in the vertical plane projection along the conveying direction of the conveying plate 13, the second protrusion 1312 is located between the two first protrusions 1311, which can well make up for the interval between the first protrusions 1311, make the conveying smoother, and avoid the problem of pills getting stuck.

[0025] More preferably, the first protrusion 1311 , the second protrusion 1312 , and the conveying plate 13 are an integrally formed structure. The integrally formed structure can ensure the stability between the first protrusion 1311 , the second protrusion 1312 , and the conveying plate 13 .

[0026] In this embodiment, a discharge plate 14 connected to the conveying plate 13 is further provided in the box body 1, and the discharge plate 14 is arranged at an angle, and the discharge plate 14 is used to guide the pills on the conveying plate 13 to the discharge pipe 12. In order to ensure the smoothness of the discharge of the pills, the discharge plate 14 connected to the conveying plate 13 is provided in the box body 1, and the discharge plate 14 is arranged at an angle, so that the dried pills can fall along the inclination of the discharge plate 14.

[0027] Preferably, the hot air delivery unit 2 includes a hot air output mechanism 21 , a delivery pipe 22 connected to the hot air output mechanism 21 , and a plurality of hot air output pipes 23 connected to the delivery pipe 22 , and the hot air output pipes 23 are connected to the bottom of the box body 1 .

[0028] Specifically, when in use, the hot air conveying mechanism conveys the hot air into the conveying pipe 22, and then outputs the hot air from the hot air output pipe 23 through the conveying pipe 22, and delivers the hot air into the box body 1. It should also be noted here that during the conveying process, the hot air needs to be pressurized so that the output hot air can drive the movement of the pills.

[0029] In this embodiment, a control valve 231 is provided on the hot air output pipe 23. The control valve 231 can better control the hot air.

[0030] Optionally, the outer side of the box body 1 is further provided with a plurality of visual windows 15 arranged along the length direction of the box body 1. The visual windows 15 can be used to observe the status of the pills inside when necessary.

[0031] Preferably, an exhaust pipe 16 connected to the interior of the box 1 is provided at the top of the box 1. The moisture and heat generated during the drying process need to be removed in time to maintain ventilation and air exchange in the drying room to prevent moisture from being retained indoors and affecting the drying effect and product quality; the exhaust pipe 16 can effectively exhaust moisture and heat to the outside, maintain a dry environment in the drying room, and improve drying efficiency and product quality; although hot air will be exhausted during the drying process, the exhaust pipe 16 still needs to be provided to ensure the circulation of indoor air and the drying effect.

[0032] The above is only a preferred embodiment of the present invention. It should be pointed out that a person skilled in the art can make several improvements or modifications without departing from the principle of the present invention. These improvements or modifications should also be regarded as within the protection scope of the present invention.
