Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of granulation and drying, and more specifically to a granulation and drying device for traditional Chinese medicine. Background Art
[0002] Chinese medicine refers to medicines that are collected, processed, and prepared under the guidance of traditional Chinese medical theory, and whose mechanism of action is explained and clinical application is guided. In short, Chinese medicine refers to substances that are used to prevent, treat, and diagnose diseases and have rehabilitation and health care effects under the guidance of traditional Chinese medicine theory. Chinese medicine mainly comes from natural medicines and their processed products, including herbal medicines, animal medicines, mineral medicines, and some chemical and biological medicines. The most commonly used granulation technology for Chinese medicine is wet granulation, which is prepared by mixing Chinese medicine extracts with excipients. The prepared wet granules are dried to remove moisture from the granules. For this purpose, a granulation drying device is proposed for drying Chinese medicine granules.
[0003] After searching, for example, a Chinese patent application with application number CN202223324095.1 discloses a drying device for Chinese medicine granulation, in which a filter plate is driven by a motor to move back and forth so that the Chinese medicine particles above the filter plate are fully and preliminarily dried. The temperature in the drying cylinder is graded by the use of a heat-insulating plate and a drying mechanism, so that the Chinese medicine particles are first preliminarily dried and then hot air dried to prevent the sugar in the Chinese medicine particles from melting when suddenly encountering high temperature, causing the particles to harden or even disintegrate, thereby causing losses.
[0004] However, when the above scheme is used, an air pump is used to draw air and a heater is used to heat the air. The drawn air contains moisture, and the heated air is used to dry the Chinese medicine particles. However, after the Chinese medicine particles are dried, a large amount of water vapor will be included in the hot air. The above scheme is not ideal for discharging water vapor, which makes it difficult to discharge water vapor and affects the degree of drying of the particles. In addition, the above scheme achieves stirring of the Chinese medicine particles by rotating the stirring plate, which easily crushes the particles during the stirring process, thereby reducing the qualified rate of the particles. Utility Model Content
[0005] In order to overcome the above-mentioned defects of the prior art, an embodiment of the utility model provides a Chinese medicine granulation and drying device, and the technical problems to be solved are: the moisture content of the air drawn in is relatively large, and the water vapor is difficult to be discharged, which affects the drying degree of the Chinese medicine granules, and stirring easily causes the granules to be crushed, affecting the qualified rate.

[0017] Technical effects and advantages of the utility model:
[0018] 1. The utility model uses two vacuum pumps to draw air into the drying frame, and the air passes through the air drying plate to filter the moisture in the air.

[0028] like Figure 3 As shown, the exhaust heating device 2 includes four air intake frames 21, and the four air intake frames 21 are respectively opened on the four sides of the drying frame 5. A limiting frame 24 is fixedly provided inside the air intake frame 21, and a connecting frame 22 is movably provided on one side of the limiting frame 24.

The filtered air passes through the heating wires 27 to heat the air, and then enters the drying cylinder 1 to dry the Chinese medicine particles, thereby achieving the drying effect of the Chinese medicine particles. The air attached with water vapor after drying is extracted by the exhaust pump 4, thereby achieving the overall effect of filtering the air and discharging water vapor, thereby preventing water vapor from affecting the drying effect of the Chinese medicine particles.
[0029] Furthermore, in order to reduce the crushing of the Chinese medicine particles due to stirring, a particle stirring device 3 capable of stirring the Chinese medicine particles is provided inside the drying cylinder 1, which is used to evenly stir the Chinese medicine particles.

A plurality of through holes are provided in the convex air permeable cover 35 to allow hot air to pass through the through holes.
