[0002] The production process of solid preparations of traditional Chinese medicine usually includes granulation, drying, granulation, and total mixing. The existing technology generally adopts split settings and single-machine operation for different processes. The corresponding equipment is granulator (including wet granulation, dry granulation, one-step granulation, etc.), dryer (including vertical dryer, horizontal dryer, etc.), granulator (including wet granulation, dry granulation, etc.), total mixer (including one-dimensional mixer, two-dimensional mixer, three-dimensional mixer, multi-dimensional mixer, etc.). Among them, granulation is the key operation in the production of solid preparations of traditional Chinese medicine. Granulation is the operation of processing materials in the state of powder, molten liquid, aqueous solution, etc. into granules with a certain shape and size. Granulation can not only improve the fluidity, scattering, and adhesion of materials, but also ensure the uniformity of particle size, shape, and appearance, which is convenient for tableting, capsule filling, and preparation of granules. Granulation is to increase the fluidity of materials to ensure good compression molding of particles, avoid cracking and loose tablets, and reduce the weight difference of tablets.

[0003] The granulation process is completed in different production equipment. During the wet granulation process, the wet Chinese medicine granules are easily polluted in the production workshop and affect the health of workers. At the same time, the wet Chinese medicine granules are not guaranteed during the transfer process and are easily contaminated by other dust and impurities. In addition, the wet Chinese medicine granules are easily broken during the transportation process, which affects the production efficiency. Utility Model Content

[0019] like Figure 1-3 As shown, the embodiment of the utility model provides a wet granule drying and conveying device for Chinese medicine production, including an outer shell 1, a conveyor belt 2 for conveying granules is arranged inside the outer shell 1, and a driving device and components for driving the conveyor belt 2 to operate are installed on the outer shell 1, which can drive the conveyor belt 2 to convey wet Chinese medicine granules. A feed hopper 10 is installed above the outer shell 1, and the end of the feed hopper 10 away from the outer shell 1 is connected to the discharge end of the granulator, and a discharge port 11 is arranged on the right side of the outer shell 1, and the discharge port 11 is connected to the dryer, which can directly convey the wet Chinese medicine granules produced by the granulator to the dryer through the conveying device, and dry the wet Chinese medicine granules, so that the wet Chinese medicine granules can be prevented from piling up during transportation, causing the wet Chinese medicine granules to break, ensuring the integrity of the Chinese medicine granules, thereby reducing the damage of the Chinese medicine granules, and thus improving the production efficiency. In addition, the outer shell can reduce the contact between the wet Chinese medicine particles and the outside world, thus preventing the wet Chinese medicine particles from causing pollution during transportation and protecting the health of workers. It can also prevent the wet Chinese medicine particles from being contaminated during transportation, reduce the loss of contaminated Chinese medicine, and further improve production efficiency.

[0020] An air inlet duct 3 is installed above the outer shell 1, an air intake fan 4 is installed inside the air inlet duct 3, an air supply duct 5 is installed above the air inlet duct 3, a heat exchange box 6 is installed at one end of the air supply duct 5 away from the air inlet duct 3, a plurality of equidistantly arranged aluminum sheets 8 are installed on the right side of the heat exchange box 6, a connecting pipe 9 is installed on the right side of the heat exchange box 6, and the lower end of the connecting pipe 9 is connected to the exhaust end of the dryer. The left part of the aluminum sheet 8 is located inside the heat exchange box 6, and the right part of the aluminum sheet 8 is located inside the connecting pipe 9. The hot air discharged from the dryer can heat the aluminum sheet 8 in the connecting pipe 9, and the aluminum sheet 8 transfers the heat to the aluminum sheet 8 of the heat exchange box 6. The air intake fan 4 is started, and the heat of the aluminum sheet 8 is taken away when the wind passes through the aluminum sheet 8 of the heat exchange box 6. The temperature of the wind rises, and the hot air can enter the outer shell 1 along the air duct 5, and then the wet Chinese medicine particles on the conveyor belt 2 are pre-heated and dried, which can improve the drying efficiency of the Chinese medicine particles. Since the hot air discharged from the dryer is used, it is the reuse of the hot air, which achieves the effect of saving energy.

[0021] Furthermore, an air inlet 13 is installed at the upper end of the heat exchange box 6, and a filter 14 is installed at one end of the air inlet 13 away from the heat exchange box 6. The filter 14 can prevent external pollutants from entering the device and prevent wet Chinese medicine particles from being contaminated.

[0022] Furthermore, the feed hopper 10 is arranged on the left part above the outer shell 1, the air inlet pipe 3 is arranged on the right part above the outer shell 1, and the left side surface of the outer shell 1 is provided with an air outlet 12, which can allow wet Chinese medicine particles to enter from the left end of the device, and hot air is blown from the right end of the device and blown out from the left end of the device, so that the time of hot air in the outer shell 1 is prolonged, the preheating and drying time of the wet Chinese medicine particles is prolonged, and the preheating and drying effect of the Chinese medicine particles is improved.

[0023] When in use, by connecting the lower end of the connecting pipe 9 to the exhaust end of the dryer, the end of the feed hopper 10 away from the outer shell 1 is connected to the discharge end of the granulator, and the discharge port 11 is connected to the dryer. After the dryer discharges hot air to heat the aluminum sheet 8 in the connecting pipe 9, the air intake fan 4 is started, and the air passes through the filter 14 and enters the heat exchange box 6 from the air inlet 13. When the wind passes through the aluminum sheet 8 of the heat exchange box 6, the heat of the aluminum sheet 8 is taken away. The temperature of the wind increases, and the hot air can enter the outer shell 1 along the air delivery pipe 5, thereby pre-heating and drying the wet Chinese medicine particles on the conveyor belt 2, which can improve the drying efficiency of the Chinese medicine particles. At the same time, the wet Chinese medicine particles produced by the granulator are directly transported to the dryer through the conveying device, and the wet Chinese medicine particles are dried, which avoids the wet Chinese medicine particles from being contaminated and broken, ensures the integrity of the Chinese medicine particles, and reduces the damage of the Chinese medicine particles, thereby improving the production efficiency.

[0024] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
