Description

Technical Field

[0001] This utility model relates to the field of drying equipment technology, specifically a drying equipment for traditional Chinese medicine extracts. Background Technology

[0002] Drying of Chinese herbal extracts is a crucial step in the production of Chinese herbal preparations. Its core function is to achieve the three major goals of "stabilization, functionalization, and practicality" by removing moisture or organic solvents from the extracts, thus providing a foundation for subsequent preparation processing (such as making tablets, capsules, and powders) and storage and transportation. The natural medicinal parts of Chinese herbs are the key raw materials for extracting. Because the moisture content of Chinese herbs is high after harvesting, they need to be dried in advance.

[0003] A prior art patent with publication number CN212081884U discloses a base and a top seat fixed above the base by two symmetrically arranged columns. A mounting frame is fixedly installed on the top of the base, and the mounting frame has a recessed assembly opening. A drying roller is rotatably connected within the assembly opening, and a cover plate is hinged to the drying roller, closing it. Both ends of the drying roller pass through the mounting frame and are fixedly connected to driven gears. A lifting motor is fixedly installed at the center of the bottom of the assembly opening, and the telescopic end of the lifting motor is driven by a heating seat. The top of the heating seat has a recessed heating groove, and a heating plate is fixedly installed within the heating groove, adapting to the drying roller. A lifting cylinder is fixedly installed at the center of the top of the top seat. This utility model relates to the field of traditional Chinese medicine processing equipment technology, improving the drying efficiency of traditional Chinese medicine extracts, and is practical and economical.

[0004] With use, existing devices, including those mentioned above, have gradually revealed shortcomings in this technology, mainly in the following aspects: First, existing Chinese medicinal materials occupy a large horizontal space when being dried, and the materials of different heights are prone to shading during the drying process, which affects the drying efficiency of the Chinese medicinal materials.

[0005] Secondly, during the drying process, the drying airflow restricts the contact between the raw materials and the drying process, thus reducing the drying efficiency of the raw materials.

[0006] In conclusion, the existing technology obviously has inconveniences and defects in practical use, so it is necessary to improve it. Utility Model Content

[0007] In view of the shortcomings of the existing technology, this utility model solves the problem that the drying efficiency of Chinese herbal raw materials is reduced because the drying airflow is limited during the drying process and cannot make uniform contact with the raw materials.

[0008] To solve the above problems, this utility model provides the following technical solution: A drying device for traditional Chinese medicine extracts includes a support base, on which an air supply pipe is vertically fixed. Several support sleeves are arranged side by side from top to bottom on the air supply pipe, and the support sleeves are rotatably arranged with their axes as the rotation center. An air distribution pipe is horizontally fixed to the outer wall of the support sleeve and is connected to the inner cavity of the air supply pipe. The other end of the air distribution pipe is connected to a support shell that slides horizontally. The inner cavity of the support shell is connected to the air distribution pipe. The upper end of the support shell is open. An air distribution plate is horizontally fixed inside the support shell. Air distribution holes are evenly distributed on the air distribution plate, and a material storage mesh frame is supported on the air distribution plate.

[0009] As an optimized solution, the air supply pipe is provided with a number of air outlets around each of the support sleeves, the inner wall of the support sleeve is provided with an annular groove, the number of air outlets are connected to the annular groove, and the support sleeve is provided with a connecting hole that connects the annular groove to the air distribution pipe.

[0010] As an optimized solution, a support tube is horizontally inserted at the other end of the air distribution pipe, and the other end of the support tube is fixedly connected to the outer wall of the support housing, and the support tube communicates with the inner cavity of the support housing.

[0011] As an optimized solution, the upper end of the air distribution pipe is threaded with a positioning knob, and the end of the positioning knob abuts against the outer wall of the support pipe.

[0012] As an optimized solution, several positioning grooves are arranged side by side along the axial direction on the outer wall of the support tube, and the end of the positioning knob abuts against one of the positioning grooves.

[0013] As an optimized solution, a regulating valve is fixedly connected to the air distribution pipe.

[0014] As an optimized solution, the air supply pipe has an external thread section in the area below each air outlet hole, and a counter nut is threadedly connected through the external thread section. The lower surface of the support sleeve rubs against the upper surface of the counter nut.

[0015] As an optimized solution, two sealing rings are arranged side by side on the inner wall of the support sleeve, and the two sealing rings are located on the upper and lower sides of the air outlet.

[0016] As an optimized solution, an annular groove is formed on the inner wall of the support sleeve, and the sealing ring is fitted into the annular groove.

[0017] As an optimized solution, an air inlet pipe communicating with its inner cavity is fixedly connected to the outer wall of the air supply pipe near its lower end, and an air source is fixed on the support base, with the outlet end of the air source connected to the air supply pipe.

[0018] As an optimized solution, handles are fixed to the opposite outer walls of the storage mesh frame.

[0019] As an optimized solution, a plug is fixed to the upper end of the air supply pipe.

[0020] Compared with the prior art, the beneficial effects of this utility model are: The fact that each support sleeve can rotate allows adjacent support shells to rotate circumferentially to avoid each other, reducing the phenomenon of shading and improving the uniformity of drying of Chinese herbal medicine raw materials in different layers. The system utilizes a wind source to supply air to the air supply pipe. The air flows through the air outlet, connecting hole, air distribution pipe, and support pipe into the support shell. Then, through the evenly distributed air distribution holes on the air distribution plate, the air is sprayed evenly onto the Chinese herbal raw materials in the upper storage mesh frame to dry the raw materials. This increases the uniformity of contact between the drying airflow and the raw materials. Combined with sun drying, it achieves double drying and improves the quality of the raw materials during subsequent extraction. Attached Figure Description

The inner cavity of the support shell 5 is connected to the air distribution pipe 4. The upper end of the support shell 5 is open. An air distribution plate 6 is horizontally fixed inside the support shell 5. Air distribution holes are evenly distributed on the air distribution plate 6. A storage mesh frame 7 is supported on the air distribution plate 6.

[0026] The storage mesh frame 7 is used to hold the raw materials of traditional Chinese medicine. The storage mesh frame 7 and the supporting shell 5 are set separately, which facilitates loading and unloading.

[0027] The air supply pipe 2 is provided with several air outlets 17 around each support sleeve 3. The inner wall of the support sleeve 3 is provided with an annular groove 18. The several air outlets 17 are connected to the annular groove 18. The support sleeve 3 is provided with a connecting hole 20 that connects the annular groove 18 to the air distribution pipe 4. By setting the annular groove 18, it is ensured that the air outlets 17 in the same circle are connected to the connecting hole 20, so as to prevent interference caused by the rotation of the support sleeve 3.

[0028] The other end of the air distribution pipe 4 is horizontally inserted with a support pipe, and the other end of the support pipe is fixedly connected to the outer wall of the support housing 5. The support pipe is connected to the inner cavity of the support housing 5.

[0029] The upper end of the air distribution pipe 4 is threaded with a positioning knob 10.
