Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of traditional Chinese medicine processing equipment, specifically a rotary drying device for traditional Chinese medicine materials. Background Technology
[0002] Drying is a crucial step in the production of traditional Chinese medicine. Its purpose is to remove moisture from the medicinal materials, prevent them from becoming moldy and deteriorating, and facilitate subsequent storage, transportation, and preparation. Traditional methods of drying Chinese medicinal materials are mostly static drying, which involves spreading the medicinal materials flat on a tray or drying rack and placing them in drying equipment for heating and drying.
[0003] However, this static drying method has many drawbacks. On the one hand, during the drying process, the moisture inside the Chinese medicinal materials is difficult to dissipate due to the accumulation of the materials, resulting in uneven drying. Some materials may be over-dried or even charred, while others have not yet reached the ideal degree of dryness, which seriously affects the quality and efficacy of the Chinese medicinal materials. On the other hand, static drying is less efficient and takes longer, which increases production costs.
[0004] To address the aforementioned technical problems, a rotary drying device for traditional Chinese medicine materials is proposed. Utility Model Content
[0005] In view of the shortcomings of the prior art, this utility model provides a rotary drying device for traditional Chinese medicine materials, which overcomes the shortcomings of the prior art and solves the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a rotary drying device for traditional Chinese medicine materials, comprising a drying chamber, a rotary unit, a rotary drive mechanism, a hot air circulation system, and a temperature and humidity control module;
[0007] The flipping unit consists of a drying chamber that is rotatably installed inside the drying box. The surface of the drying chamber has through holes, the inner wall of the drying chamber is fixedly installed with a partition plate, and the middle of the outer wall of the drying chamber is fixedly installed with an arc-shaped toothed rack.
[0008] The flipping drive mechanism includes a self-locking motor, a transmission gear set, and transmission gears;
[0009] The hot air circulation system consists of a heater and a centrifugal fan.
[0010] Place the herbs to be dried inside the feed inlet. The inclined surface at the bottom of the feed inlet guides the herbs into the drying chamber. The feed inlet is located directly above the drying chamber. After entering the drying chamber, the herbs fall into the drying chamber. The drying temperature and rotation interval are set by the PLC controller. The hot air circulation system is started. The centrifugal fan delivers hot air through the through holes to the inside of the drying chamber and evenly passes through the herb layer. Moisture is discharged outward from the feed inlet at the top of the drying chamber. The self-locking motor drives the drying chamber to rotate 120° every 5 minutes through the transmission gear set. The herbs are naturally loosened when they fall. The machine automatically stops when the humidity sensor detects that the humidity is ≤15%.
[0011] As a preferred embodiment of this utility model, the top of the drying chamber is provided with a feed inlet, the cross-section of which is V-shaped, and a material handling cover is hinged to the outer wall of the drying chamber.
[0012] The V-shaped structure of the feed inlet makes it easy to add medicinal materials, and the feed cover can be opened after the medicinal materials are dried, making it easy to take out the dried medicinal materials.
[0013] As a preferred embodiment of this utility model, both ends of the drying chamber are equipped with vibration motors, and a receiving box is installed between the drying chamber and the material receiving cover. A debris collection tray is fixedly connected to the outer wall of the receiving box.
[0014] The vibrating motor helps to break up the medicinal materials during drying, and also helps the debris fall through the through holes into the debris collection tray. The receiving box is used to collect the dried medicinal materials inside the drying chamber. The drying chamber rotates to the receiving box side, and the medicinal materials slide into the receiving box along the inner wall of the drying chamber by their own gravity.
[0015] As a preferred technical solution of this utility model, the transmission gear and the arc-shaped rack are meshed together.
[0016] As a preferred embodiment of this utility model, the heaters are symmetrically installed on the inner wall of the drying chamber, and the heaters have mounting positions adapted to the centrifugal fan.
[0017] The herbs are heated by a heater and then circulated by a centrifugal fan to dry them.
[0018] As a preferred technical solution of this utility model, the temperature and humidity control module consists of a temperature sensor, a humidity sensor and a PLC controller. The temperature sensor and the humidity sensor are both fixedly installed on the inner wall of the drying chamber, and the PLC controller is fixedly installed on the outer surface of the drying chamber.
[0019] The PLC controller adjusts the hot air temperature and rotation frequency based on real-time data.
[0020] Compared with the prior art, the beneficial effects of this utility model are:
[0021] The drying temperature and rotation interval are set by the PLC controller. The hot air circulation system starts and the centrifugal fan delivers hot air through the through holes to the inside of the drying chamber and evenly passes through the herb layer. Moisture is discharged outward from the feed port at the top of the drying chamber. The self-locking motor drives the drying chamber to rotate 120° every 5 minutes through the transmission gear set. The periodic rotation allows the herbs to be heated from multiple sides, improving the drying efficiency. The herbs naturally loosen when they fall. The machine automatically stops when the humidity sensor detects that the humidity is ≤15%. Attached Figure Description
