Description

Technical Field

[0001] The utility model belongs to the technical field of machinery and relates to a capsule drying box, in particular to a capsule drying box capable of achieving uniform drying. Background Art

[0002] Capsules are capsules made of special film-forming materials (such as gelatin, cellulose, polysaccharides, etc.), which are filled with contents (such as powdered or liquid drugs, etc.) or dosed according to dosage for easy swallowing. Capsules are usually divided into hard capsules and soft capsules. Hard capsules are also called hollow capsules, usually gelatin capsules and plant capsules. Plant capsules are hollow capsules made of plant cellulose or water-soluble polysaccharides. They meet the needs of all-natural positioning and capsule preparation solutions, and retain the advantages of hollow capsules: easy to take, transparent and visible contents, etc.

[0003] After the capsule is formed on the production line, the temperature of the capsule glue is relatively high, so the capsule needs to be cooled and solidified to prevent the glue on the capsule from flowing and affecting the quality of the finished capsule. At the same time, the capsule needs to be dried to keep the capsule dry as a whole, which is convenient for subsequent packaging and storage.

[0004] In view of the many shortcomings of the early capsule drying process, such as: uneven temperature distribution in the drying room, uneven air humidity distribution, unreasonable air circulation, uneven heating of capsules, long drying cycle, and high energy consumption.

[0005] The existing capsule drying basically sets up a long channel on the production line. After the capsule is initially shaped on the mold bar, it is dried by the conveyor belt of the crawler type shaping dryer. Most of the moisture on the surface of the capsule evaporates, and it enters the drying room again from the discharge port to continue drying and complete the final drying operation. However, this drying mode still has some disadvantages: on the one hand, the drying efficiency is low; on the other hand, the air duct is single and the air supply is uneven. In addition, since the crawler type drying system cannot discharge moisture, the capsule is not dried evenly, which easily leads to the capsule cracking or adhesion, and the yield rate after the drying process is low.

[0006] In summary, in order to solve the structural deficiencies of the existing capsule drying devices, the utility model designs a capsule drying box with a reasonable structure and good drying effect. Summary of the invention

[0007] The utility model provides a capsule drying box with reasonable structure and good drying effect in order to solve the problems existing in the prior art.

[0008] The purpose of the utility model can be achieved through the following technical solutions: a capsule drying box, comprising:

[0009] The outer box body is hollow and has an opening door installed on the surface of the outer box body;

[0010] The inner box is built into the outer box. Several layers of brackets for placing capsules are fixed in the inner box. Several rows of through holes are evenly distributed from top to bottom around each side of the inner box. The inner box and the outer box together form a cavity.

[0011] The controller is arranged on one side of the outer box body. A vortex tube is installed in the controller. One end of the vortex tube is connected to the side of the outer box body, and the other end extends outward and is connected to the back of the outer box body. The vortex tube can input cold and hot air flows into the corresponding box body.

[0012] As a further improvement of the present invention, a connection groove connected to the vortex tube is provided on the side of the outer box body, and a connection hole connected to the vortex tube is provided on the back of the outer box body.

[0013] As a further improvement of the present invention, a row of through holes is distributed between two adjacent brackets, and the corresponding rows of through holes on each side surface of the inner box body are arranged flush.

[0014] As a further improvement of the present invention, each bracket is hollowed out.

[0015] As a further improvement of the present invention, a transparent cover is embedded on the opening door surface.

[0016] Compared with the prior art, the utility model has a reasonable structural arrangement. Through the arrangement of the vortex tube, two air sources, namely, cold airflow and hot airflow, can be provided at the same time. At the same time, the vortex tube is arranged in coordination with the inner box, the outer box and the cavity to achieve smooth circulation of gas in the drying box, which is beneficial to the drying of the capsules.

[0022] The technical solution of the utility model is further described below in conjunction with the embodiments and drawings.

[0023] like Figures 1 to 4 As shown, the capsule drying box includes:

[0024] The outer box body 10 is hollow, and an opening door 14 is installed on the surface of the outer box body 10;

[0025] The inner box body 20 is built in the outer box body 10. The inner box body 20 is fixed with multiple layers of brackets 21 for placing capsules. Multiple rows of through holes 22 are evenly distributed from top to bottom around each side of the inner box body 20. The inner box body 20 and the outer box body 10 are surrounded to form a cavity 13.

[0026] The controller 30 is arranged on one side of the outer box body 10. A vortex tube (not shown in the figure) is installed in the controller 30. One end of the vortex tube is connected to the side of the outer box body 10, and the other end extends outward and is connected to the back of the outer box body 10. The vortex tube can input cold and hot air flows into the corresponding box body.

[0027] The existing capsule drying basically sets up a long channel on the production line. After the capsule is initially shaped on the mold bar, it is dried by the conveyor belt of the crawler type shaping dryer. Most of the moisture on the surface of the capsule evaporates, and it enters the drying room again from the discharge port to continue drying and complete the final drying operation. However, this drying mode still has some disadvantages: on the one hand, the drying efficiency is low; on the other hand, the air duct is single and the air supply is uneven. In addition, since the crawler type drying system cannot discharge moisture, the capsule is not dried evenly, which easily leads to the capsule cracking or adhesion, and the yield rate after the drying process is low.

[0028] To this end, the utility model provides a capsule drying box, which provides two air sources, cold air flow and hot air flow, through the setting of a vortex tube. The vortex tube is coordinated with the inner box 20, the outer box 10 and the cavity 13 to achieve smooth circulation of gas in the drying box, which is beneficial to the drying of the capsules.

[0029] Specifically, the drying box is preferably formed by an inner box body 20 and an outer box body 10, a cavity 13 is set between the inner and outer box bodies 10, and a through hole 22 is opened around the inner box body 20, so that the inner box body 20 is connected to the outer box body 10 through the cavity 13, which facilitates the circulation of airflow between the inner and outer box bodies 10, so that the capsules are fully in contact with the airflow, and a good drying effect is achieved.

[0030] The air flow source of the drying box is provided by an external controller 30. Preferably, a vortex tube is arranged in the controller 30. The vortex tube can act on the compressed air to separate cold and hot air flows. Here, the vortex tube preferably passes the cold and hot air flows into the drying box respectively to dry the capsules and obtain high-quality finished capsules.

[0031] Preferably, a connecting groove 11 communicating with the vortex tube is formed on the side of the outer box body 10 , and a connecting hole 12 communicating with the vortex tube is formed on the back of the outer box body 10 .

[0032] In this embodiment, one end of the vortex tube preferably inputs the cold air flow and the hot air flow into the cavity 13 through the connecting groove 11 on the outer box 10, wherein the hot air flow further enters the inner box 20 through the through holes 22 on the inner box 20, and the hot air flow rises in the inner box 20 to dry the capsules from bottom to top in sequence; after the heat transfer, the hot air flow returns to the cavity 13 and flows downward, and the hot air flow can circulate between the outer box 10, the inner box 20 and the cavity 13, and also provides a dry environment for the entire box to ensure that the capsules are fully dried.

[0033] The cold airflow is output outward through the cavity 13 and the connecting hole 12 and returns to the vortex tube again. The hot airflow also finally returns to the vortex tube through the connecting hole 12. The hot airflow and the cold airflow return to the vortex tube again and can be reused as part of the airflow source (compressed air), thereby improving the utilization rate of compressed air, relatively reducing production costs, and being beneficial to actual production applications.

[0034] Furthermore, a row of through holes 22 is distributed between two adjacent brackets 21 , and the rows of through holes 22 correspondingly arranged on each side surface of the inner box body 20 are arranged flush.

[0035] In actual operation, the capsules that have been initially shaped are loaded onto the respective brackets 21 of the inner box 20 using a tray or the like. Preferably, a row of through holes 22 is distributed between two adjacent brackets 21, that is, each row of through holes 22 on the inner box 20 is arranged corresponding to each bracket 21, so that when the airflow is input into the inner box 20 from the through holes 22, it can quickly contact the capsules for drying; the airflow is more concentrated and has a high utilization rate; at the same time, it is convenient for the hot airflow to circulate between the inner box 20 and the cavity 13, which is beneficial to the drying of the capsules.

[0036] In addition, it is preferred that the rows of through holes 22 on each side of the inner box 20 are arranged flush, so that the hot air flow can not only blow the capsules from bottom to top, but also circulate between the cavity 13 and the inner box 20, so that it can blow to the capsules of the corresponding layer from all directions, ensuring that the capsules are fully in contact with the air flow, thereby improving the drying efficiency of the capsules.

[0037] Preferably, each bracket 21 is hollowed out. In this embodiment, the bracket 21 is preferably hollowed out to facilitate smooth airflow in the inner box 20, thereby accelerating the flow rate of the entire air in the box, improving the air circulation between the inner box 20 and the cavity 13, and further improving the drying effect on the capsule. At the same time, the drying speed of the capsule is also accelerated, making the drying faster.

[0038] Furthermore, a transparent cover 15 is embedded on the surface of the opening door 14. The opening door 14 on the surface of the outer box 10 is preferably provided with a transparent cover 15, so that the operator can observe the drying condition of the capsules in the box. The operator can timely adjust the corresponding operation of the vortex tube in the controller 30 according to the actual drying condition of the capsules, thereby adjusting the input rate and flow ratio of the cold air flow and the hot air flow, providing good working conditions for capsule drying and achieving good drying effect.

[0039] The capsule drying box has a reasonable structure. Through the setting of the vortex tube, it can provide two air sources, namely, cold air flow and hot air flow. At the same time, the vortex tube is coordinated with the inner box 20, the outer box 10 and the cavity 13 to achieve smooth circulation of gas in the drying box, which is beneficial to the drying of the capsules. In addition, the through holes 22 cooperate with the cavity 13 to achieve good air flow in the entire drying box and high air source utilization.

[0040] The preferred embodiments of the present invention are described herein, but the protection scope of the present invention is not limited thereto. Any modification or supplement or replacement of the specific embodiments described by technicians in the field of the present invention shall be included in the protection scope of the present invention.
