[0002] In the production of traditional Chinese veterinary medicine, drying concentrated granules is a crucial step. Traditional drying methods have many drawbacks and cannot meet the demands of modern production.
[0003] Early drying equipment was mostly simple static drying devices that relied on natural ventilation or ordinary heating. This method was not only inefficient and time-consuming, but also resulted in uneven heating, which could lead to some veterinary medicine granules being over-dried, destroying their active ingredients, while other granules were under-dried, resulting in excessive moisture content and affecting product quality.
[0004] With technological advancements, some improved drying equipment has emerged, but problems still exist. Some equipment cannot accurately control temperature and humidity. During the drying process, due to unstable temperature and humidity changes, granules of traditional Chinese veterinary medicine are prone to clumping, which not only affects the appearance and flowability of the granules but may also reduce their efficacy. Moreover, these devices have unreasonable structural designs, are bulky, occupy a lot of production space, and have high energy consumption, which increases production costs and is not conducive to mass production.

[0036] like Figures 1-4 As shown, it illustrates a drying apparatus for concentrated veterinary drug granules according to an embodiment of this disclosure, comprising:
[0037] The outer casing 1 and the circulating fan 2 are mounted on the side surface of the outer casing 1.
[0038] Temperature sensor 3 and controller 6 are provided. Temperature sensor 3 is disposed on the inner surface of housing 1 and controller 6 is mounted on the outer wall of housing 1.
[0039] The circulating drying component 4 is disposed in the outer casing 1;
[0040] The enclosed inlet / outlet assembly 5 is disposed outside the housing 1;
[0041] The circulating drying assembly 4 includes a top cover 4-1, which is located on the top of the outer shell 1. Several heating tubes 4-2 are installed inside the top cover 4-1. The top cover 4-1 is connected to the output end of the circulating fan 2 and is connected to the top of the outer shell 1. A return air duct 4-3 is connected between the return end of the circulating fan 2 and the bottom of the outer shell 1. A drive motor 4-4 is installed on the side surface of the outer shell 1. An annular slide rail 4-5 is installed on the inner surface of the outer shell 1. A roller 4-6 is slidably connected on the annular slide rail 4-5. The roller 4-6 is connected to the output end of the drive motor 4-4. An inner cylinder 4-7 is installed inside the roller 4-6. One end of the inner cylinder 4-7 is open. Dispersing air holes 4-8 are opened on the surfaces of both the roller 4-6 and the inner cylinder 4-7. Spiral blades 4-9 are arranged around the inner surface of the roller 4-6.
[0042] In some examples, a circulating drying assembly 4 is designed to achieve hot air circulation and rolling drying effects. This assembly includes a top cover 4-1 mounted on top of the outer casing 1. Several heating tubes 4-2 are installed inside the top cover 4-1 to generate heat. The top cover 4-1 is connected to the output end of the circulating fan 2 and communicates with the top of the outer casing 1. The circulating fan 2 sends the heated air inside the top cover 4-1 into the outer casing 1. The return air end of the circulating fan 2 is connected to the bottom of the outer casing 1 through a return air pipe 4-3, allowing air to circulate between the outer casing 1, the top cover 4-1, and the circulating fan 2. A drive motor 4-4 is mounted on the side surface of the outer casing 1, and an annular slide rail 4-5 is provided on the inner surface. A roller 4-6 is slidably connected to the slide rail, and the roller 4-6 is connected to the output end of the drive motor 4-4. The drive motor 4-4 drives the drum 4-6 to rotate on the annular slide rail 4-5. The material will continuously tumble inside the drum 4-6. The drum 4-6 is equipped with an inner cylinder 4-7 with an open end. Both the drum 4-6 and the inner cylinder 4-7 have dispersion holes 4-8 to facilitate the entry of hot air and full contact with the drug particles. The inner surface of the drum 4-6 is equipped with spiral blades 4-9. When the drum 4-6 rotates, the spiral blades 4-9 can push the drug particles to move and tumble inside the inner cylinder 4-7 and the drum 4-6, so that the drug particles are fully mixed with the hot air and the drying effect is improved. Through the air circulation and the rotation of the drum 4-6, the circulating drying component 4 can efficiently dry the drug particles. When discharging, the rotation direction of the drum 4-6 is switched to push the material out.
[0043] like Figures 1-4 As shown, this embodiment proposes a closed feeding and discharging assembly 5 including a top frame 5-1, which is fixed to the top of the outer shell 1. A telescopic cylinder 5-2 is installed inside the top frame 5-1. A sealing cover 5-3 is connected to the output end of the telescopic cylinder 5-2. A feeding hood 5-4 is provided on the outer surface of the sealing cover 5-3. The connection between the feeding hood 5-4 and the sealing cover 5-3 is an open structure. A top cover 5-5 is installed on the top of the feeding hood 5-4. A collection hood 5-6 is provided on the side surface of the outer shell 1. The collection hood 5-6 is provided with a discharge pipe 5-7. The internal dimensions of the collection hood 5-6 are larger than the diameter of the sealing cover 5-3.
[0044] In some examples, to achieve stable feeding and discharging, a closed feeding / discharging assembly 5 is designed. A telescopic cylinder 5-2 is installed inside the top frame 5-1. The output end of the telescopic cylinder 5-2 is connected to a sealing cover 5-3. Through the telescopic movement of the telescopic cylinder 5-2, the sealing cover 5-3 can be closed onto the outer shell 1, thereby controlling the opening and closing state of the outer shell 1. A feeding hood 5-4 is provided on the outer surface of the sealing cover 5-3. The connection between the feeding hood 5-4 and the sealing cover 5-3 is an open structure, which facilitates the feeding of medicine granules from the feeding hood 5-4 into the outer shell 1. The top of the material hood 5-4 is equipped with a top cover 5-5. When feeding is required, the top cover 5-5 can be opened to put the medicine granules in. When feeding is not required, the top cover 5-5 can be closed to prevent dust and other impurities from entering and keep the inside of the equipment clean. A collection cover 5-6 is provided on the side surface of the outer shell 1. A discharge pipe 5-7 is provided at the bottom of the collection cover 5-6. The internal size of the collection cover 5-6 is larger than the diameter of the sealing cover 5-3. When the sealing cover 5-3 is opened, the medicine granules can roll into the collection cover 5-6 and be discharged through the discharge pipe 5-7.
[0045] For example, such as Figure 1 As shown, the diameter of the sealing cap 5-3 matches the inner diameter of the outer shell 1, and the sealing cap 5-3 and the outer shell 1 are connected by an insert.
[0046] In some examples, by matching the dimensions, the sealing cap 5-3 can be fully embedded into the housing 1 to ensure a tight seal.
[0047] For example, such as Figure 1 As shown, the collection hood 5-6 has a semi-circular structure.
[0048] In some examples, a semi-circular structure is used to increase the capacity of the collection hood 5-6, preventing excessive output from causing overflow.
[0049] For example, such as Figure 2 As shown, the circulating fan 2 adopts a high-temperature resistant structure.
[0050] In some examples, the circulating fan 2 is able to receive heat circulated back from inside the casing 1 through a high-temperature resistant structure.
[0051] For example, such as Figure 3 As shown, the top of the feeding hood 5-4 has an upward-sloping opening structure.
[0052] In some examples, the upwardly sloping opening structure facilitates the complete rolling of the drug particles into the interior of rollers 4-6.
[0053] In actual use: First, the concentrated veterinary drug granules are fed into the drum 4-6 through the feeding hood 5-4, and the top cover 5-5 is closed. The telescopic cylinder 5-2 is activated to make the sealing cover 5-3 embed into the outer shell 1 to achieve a seal. The drive motor 4-4 is started to drive the drum 4-6 to rotate. At the same time, the circulating fan 2 and the heating pipe 4-2 are turned on. The heat generated by the heating pipe 4-2 is sent into the outer shell 1 through the circulating fan 2. The hot air is fully in contact with the granules through the dispersion holes 4-8. The spiral blades 4-9 push the granules to tumble in the drum 4-6 and the inner cylinder 4-7, so that the granules are evenly distributed. The heating is uniform, and the temperature sensor 3 monitors the temperature in real time and feeds it back to the controller 6. The controller 6 adjusts the power of the heating tube 4-2 and the speed of the circulating fan 2 to ensure a stable drying temperature. After drying, the telescopic cylinder 5-2 is activated to open the sealing cover 5-3, and the reverse drive motor 4-4 causes the spiral blades 4-9 to roll the medicine granules out of the drum 4-6 to the collection cover 5-6, and then discharge them through the discharge pipe 5-7. The drive motor 4-4, heating tube 4-2 and circulating fan 2 are all controlled by the controller 1, which uses a common PLC controller.
[0054] It should be noted that the above embodiments are only used to illustrate the technical solutions of this disclosure and are not intended to limit it. Although this disclosure has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this disclosure without departing from the spirit and scope of the technical solutions of this disclosure, and all such modifications and substitutions should be covered within the scope of the claims of this disclosure.
