Through drying treatment, the excess moisture can be removed, making the tablets more stable and extending their shelf life.

[0003] When the existing drying equipment dries tablets, it usually only uses hot air to dry the tablets, and cannot turn the tablets during drying. As a result, some tablets may not receive sufficient heat due to unfavorable positions, and it is easy for adjacent tablets to stick together. This not only affects the drying quality of the tablets, but also makes it difficult to separate and process the tablets in subsequent processes. Summary of the Utility Model

Detailed implementation manners

[0018] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those of ordinary skill in the technical field to which this application belongs; the terms used in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application; the terms "including" and "having" and any variations thereof in the specification and claims of this application and the above drawings are intended to cover non-exclusive inclusion. The terms "first", "second", etc. in the specification and claims of this application or the above drawings are used to distinguish different objects and not to describe a specific order.

[0019] Reference to "embodiment" herein means that a particular feature, structure, or characteristic described in connection with the embodiment can be included in at least one embodiment of this application. The phrase does not necessarily refer to the same embodiment at every occurrence in the specification, nor is it an independent or alternative embodiment mutually exclusive with other embodiments. Those skilled in the art will explicitly and implicitly understand that the embodiments described herein can be combined with other embodiments.

[0020] An embodiment of the present utility model provides a circulating drying oven for tablet processing, as Figures 1-3 shown. The circulating drying oven for tablet processing includes: a box body 1, on one side of which a rotating shaft 2 is rotatably installed; a mesh cylinder 3 welded to the rotating shaft 2 for flipping tablets; a motor 4 fixedly installed on one side of the box body 1, the output shaft of the motor 4 being fixedly connected to one end of the rotating shaft 2; a circulating drying mechanism installed on the box body 1 for drying tablets; and a moisture exhaust mechanism assembled on the box body 1 for moisture exhaust.

[0021] It should be noted that when drying tablets with existing drying equipment, hot air is usually used to dry the tablets, but the tablets cannot be turned during drying. As a result, some tablets may not receive sufficient heat due to unfavorable positions, and it is easy for adjacent tablets to stick together. This not only affects the drying quality of the tablets but also makes it difficult to separate and process the tablets in subsequent processes.

[0022] In the solution, first, the core component of the drying box is the box body 1, which serves as the main part of the entire drying equipment and provides a drying environment for the tablets. In this environment, uniform drying of the tablets is achieved through a specific mechanism. Second, in order to achieve uniform turning of the tablets, the drying box is designed with a rotating shaft 2 and a mesh cylinder 3. The rotating shaft 2 is rotatably installed on one side of the box body 1, and the mesh cylinder 3 is welded to the rotating shaft 2. When the motor 4 is started, its output shaft drives the rotating shaft 2 to rotate, thereby driving the mesh cylinder 3 to flip. This design enables the tablets loaded in the mesh cylinder 3 to be continuously turned, ensuring that each tablet is evenly exposed to the hot air and preventing adjacent tablets from sticking together after drying, thus achieving uniform drying. In addition, the circulating drying mechanism is another key part. It is installed on the box body 1 and is used to generate and circulate hot air. Through the circulating drying mechanism, hot air can continuously and evenly blow towards the tablets, further improving the drying efficiency and quality. At the same time, when the temperature of the gas used by the circulating drying mechanism is relatively high, the circulating drying mechanism will stop heating the gas and only simply transport the gas until the gas temperature is relatively low before heating again, which can save electricity costs. Finally, in order to keep the drying environment dry and prevent the humidity of the gas in the box body 1 from being too high, the drying box is also equipped with a moisture exhaust mechanism. When the humidity in the box body 1 reaches a certain level, the moisture exhaust mechanism will automatically start to exhaust the moisture until the humidity drops to a certain level before closing, ensuring the smooth progress of the drying process.

[0023] In a further preferred embodiment of the present utility model, the circulating drying mechanism includes: a first blower 5 fixedly installed on the box body 1; a housing 6 welded to the bottom of the box body 1, and a plurality of heating wires 7 for heating the gas are arranged inside the housing 6; an air delivery pipe 8 fixedly installed at the exhaust end of the first blower 5, and one end of the air delivery pipe 8 extends into the interior of the housing 6; an exhaust pipe 9 fixedly installed on the housing 6, and one end of the exhaust pipe 9 extends into the interior of the box body 1. A flow dividing pipe 18 is provided at one end of the exhaust pipe 9, and a plurality of exhaust hoods are arranged on the flow dividing pipe 18; an air suction pipe 10 fixedly installed at the intake end of the first blower 5, and one end of the air suction pipe 10 extends into the interior of the box body 1.

[0024] In this embodiment, the circulating drying mechanism is used to dry the tablets. During use, the first blower 5 will transmit the gas in the box body 1 to the air delivery pipe 8 through the suction pipe 10. The air delivery pipe 8 will transmit the gas to the housing 6, enabling the multiple heating wires 7 in the housing 6 to heat the gas. The heated gas will enter the shunt pipe 18 from the exhaust pipe 9 and finally be discharged from multiple exhaust hoods. The discharged gas will dry the tablets in the mesh cylinder 3 with its own heat. Then these gases will enter the suction pipe 10 again, thus realizing the reuse of heat.

[0025] In a further preferred embodiment of the present utility model, the moisture discharge mechanism includes: a second blower 11 fixedly installed on the top of the box body 1, a suction pipe 12 fixedly installed on the air inlet end of the second blower 11, and one end of the suction pipe 12 extends into the interior of the box body 1; a through pipe 13 fixedly installed at the bottom of the box body 1; and two solenoid valves 14 respectively arranged on the suction pipe 12 and the through pipe 13.

[0026] In this embodiment, the moisture discharge mechanism is used to discharge the gas with higher humidity in the box body 1. When the humidity of the gas inside the box body 1 is high, the two solenoid valves 14 will automatically open, and the second blower 11 will discharge the moisture inside the box body 1 to the outside of the box body 1 through the suction pipe 12. The through pipe 13 will input new gas into the box body 1. When the humidity of the gas inside the box body 1 is low, the two solenoid valves 14 will automatically close, so that automatic moisture discharge can be achieved to prevent the high humidity from affecting the drying of the tablets.

[0027] In a further preferred embodiment of the present utility model, a temperature and humidity sensor 15 for detecting the temperature and humidity of the gas is fixedly installed on the inner wall of the top of the box body 1, and a controller 16 is fixedly installed on one side of the box body 1.

[0028] In this embodiment, first, a temperature and humidity sensor 15 is fixedly installed on the inner wall of the top of the box body 1. This sensor features high precision and high sensitivity, and can detect the temperature and humidity of the gas inside the box body 1 in real time, and feedback these key data to the controller 16. Through the real-time monitoring of the temperature and humidity sensor 15, we can accurately understand the environmental conditions inside the box body 1, providing a basis for subsequent adjustment of the drying parameters. As the control center of the entire drying equipment, the controller 16 receives the real-time data from the temperature and humidity sensor 15, and according to the preset drying parameters and algorithms, makes corresponding adjustments to the circulating drying mechanism and the moisture exhaust mechanism. When the temperature and humidity sensor 15 detects that the humidity inside the box body 1 is too high, the controller 16 will respond quickly and instruct the moisture exhaust mechanism to conduct moisture exhaust work on the inside of the box body 1 to ensure the drying effect of the tablets. At the same time, the controller 16 can also automatically start and stop the heating wire 7 in the circulating drying mechanism according to the change of temperature, which not only saves electricity but also enables the tablets to be dried in the optimal temperature and humidity environment. Through the coordinated use of the temperature and humidity sensor 15 and the controller 16, we have achieved precise control of the tablet drying process. This intelligent and automated design improves the drying quality and efficiency.

[0029] In a further preferred embodiment of the present utility model, a support plate 17 is fixedly installed on the inner wall of the top of the box body 1. A circular hole is provided on the support plate 17, and the inner wall of the circular hole is rotatably connected to the mesh cylinder 3.

[0030] In this embodiment, the support plate 17 and the circular hole can play a stable supporting role for the mesh cylinder 3, enabling the mesh cylinder 3 to remain stable during rotation to avoid shaking.

[0031] In a further preferred embodiment of the present utility model, an opening for taking in and out tablets is provided on one side of the box body 1. A switch door 19 is provided on the opening, and a handle is fixedly installed on one side of the switch door 19.

[0032] In this embodiment, first, an opening for taking in and out tablets is provided on one side of the box body 1. The size of this opening is appropriate to meet the needs of the tablets to enter and exit. Secondly, a switch door 19 is provided on the opening. The switch door 19 is made of a durable and well-sealed material and can fit tightly on the opening to ensure the airtightness of the box body 1. In addition, in order to facilitate the operation of the switch door 19, a handle is fixedly installed on one side of it. The design of the handle conforms to ergonomics, has a comfortable grip, and can easily apply force to open or close the switch door 19.

[0033] In a further preferred embodiment of the present utility model, a plurality of support legs are fixedly installed at the bottom of the box body 1, and the bottom ends of the plurality of support legs are fixedly installed with the same bottom plate, and the bottom plate is set as a rectangle.

[0034] In this embodiment, the drying box can be stably placed on the ground for use through a plurality of support legs and a bottom plate.

[0035] To sum up, compared with the related art, in this solution, through the circulating drying mechanism, the drying box can effectively utilize heat to dry the tablets, can quickly heat the gas to the optimal temperature, and through the coordinated use of the rotating shaft 2, the mesh cylinder 3 and the motor 4, the tablets during the drying process can be turned over, ensuring that each tablet can be evenly exposed to the hot air, and at the same time preventing the adjacent tablets from sticking together after drying, avoiding the problems of uneven drying and sticking that may occur in the traditional drying method. Through the temperature and humidity sensor 15, the temperature and humidity of the gas inside the box body 1 can be detected in real time. When the temperature and humidity sensor 15 detects that the humidity inside the box body 1 is too high, the controller 16 will quickly respond and instruct the moisture exhaust mechanism to perform moisture exhaust work on the inside of the box body 1 to ensure the drying effect of the tablets. At the same time, the controller 16 can also automatically start and stop the heating wire 7 in the circulating drying mechanism according to the change of temperature, which not only saves electricity but also enables the tablets to be dried in the optimal temperature and humidity environment. Through the support plate 17 and the round holes, a stable supporting effect can be exerted on the mesh cylinder 3, so that the mesh cylinder 3 can remain stable during rotation to avoid shaking.
