Description

Technical Field

[0001] This utility model relates to the field of food and pharmaceutical processing technology, and in particular to a drying device for traditional Chinese medicine decoction pieces. Background Technology

[0002] In the traditional Chinese medicine (TCM) industry system, the drying process of processed medicinal herbs is a crucial step affecting the retention of their medicinal efficacy, quality stability, and subsequent storage. Processed medicinal herbs originate from a variety of herbs, such as rhizomes like ginseng and notoginseng, leaves like perilla and mint, and fruits and seeds like goji berries and cassia seeds. Different types and forms of processed herbs have varying and stringent requirements for parameters such as drying temperature, humidity, air velocity, and time. A new type of TCM processed herb drying device focuses on overcoming the shortcomings of traditional drying methods in areas such as precise temperature control, uniform drying, and energy efficiency. It aims to create a suitable drying environment for processed medicinal herbs by optimizing the equipment structure and thermal circulation logic, thereby improving the drying quality of the herbs, reducing the loss of effective components, meeting the needs of TCM manufacturers for standardized and efficient drying operations, promoting the upgrading of the TCM processing industry towards refinement and intelligence, and ensuring the clinical efficacy and high-quality development of the TCM industry.

[0003] Currently, traditional Chinese medicine (TCM) decoction piece drying equipment mostly consists of a box-type frame, a hot air device, and a simple material support structure. The box-type frame is generally a closed space welded from steel plates, with heat loss reduced by filling the inner walls with heat insulation material. However, its structural design often neglects the rational distribution of heat flow, easily leading to localized temperature differences. The hot air device uses electric heating tubes or coal-fired / gas-fired furnaces as heat sources, combined with axial flow fans, utilizing the principle of air convection to send heated air into the drying chamber. The simple material support is mostly a layered metal mesh tray or a trolley-type rack, relying on manual loading and unloading of materials. The mesh size and arrangement of the mesh tray lack targeted design, failing to adequately ensure the support and uniform ventilation of the decoction pieces.

[0004] In the existing technology, if the air contains impurities such as dust, pollen, and particulate matter during the drying process of traditional drying equipment, they may adhere to the surface of Chinese herbal medicine slices, affecting the purity of the slices. Traditional layered metal mesh trays or trolley-type racks are prone to uneven heating of the slices between the upper and lower layers. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a traditional Chinese medicine decoction piece drying device, which aims to improve the problem that if there are impurities such as dust, pollen, and particulate matter in the air during the drying process of traditional drying devices, they may adhere to the surface of the traditional Chinese medicine decoction pieces and affect the purity of the decoction pieces.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a drying device for traditional Chinese medicine decoction pieces, comprising a ventilation pipe, a locking assembly on one side of the outer wall of the ventilation pipe, a transmission assembly on one side of the outer wall of the ventilation pipe, the locking assembly comprising a second device housing, the second device housing being fixedly connected to the outer wall of the ventilation pipe, a centrifugal fan being fixedly connected inside the second device housing, a heating coil on one side of the outer wall of the centrifugal fan, a ventilation plate fixedly connected to one end of the heating coil, an air filter plate on one side of the outer wall of the ventilation plate, an air inlet grille on one side of the outer wall of the air filter plate, a locking block fixedly connected to the outer wall of the air inlet grille, a spring fixedly connected to one side of the outer wall of the locking block, a guide roller fixedly connected to the inner wall of the spring, a movable seat fixedly connected to the outer wall of the guide roller, a guide roller on one side of the outer wall of the movable seat, and a bolt threadedly connected to the outer wall of the guide roller.

[0008] Furthermore, a fan blade housing is fixedly connected to one inner wall of the device housing, a filter frame is fixedly connected to the inner wall of the fan blade housing, a support leg is fixedly connected to the lower surface of the device housing, a device door is provided on one inner wall of the device housing, and a handle is fixedly connected to the outer wall of the device door.

[0009] Furthermore, an air intake grille is provided at one end of the device housing, a movable seat is fixedly connected to the outer wall of the air intake grille, and a support leg is provided on the lower surface of the device housing.

[0010] Furthermore, a handle is fixedly connected to the outer wall of the air intake grille, and a heating coil is provided inside the outer casing of the device.

[0011] Furthermore, a filter frame is fixedly connected to one end of the vent pipe, and a motor is installed below the vent pipe.

[0013] Furthermore, a motor is provided at the bottom of the outer casing of the device, and a rotating material tray is provided inside the outer casing of the device.

[0014] This utility model has the following beneficial effects:

[0015] In this invention, when a traditional Chinese medicine decoction piece drying device is started, the centrifugal fan, under the suction action, draws air through the air inlet grille into the device's outer shell. The air filter removes dust, and the air is then heated by the heating coil inside the ventilation plate to form a heat flow. This heat flow is then drawn into the ventilation pipe by the centrifugal fan, providing a clean and stable thermal environment for the traditional Chinese medicine decoction pieces, ensuring drying efficiency and quality. A movable locking block drives a spring to extend and retract, with the spring and locking block moving within a movable seat. A guide roller guides the spring's extension and retraction, allowing the air inlet grille to be disassembled when cleaning the inside of the device's outer shell is required.

[0016] In this invention, the blades rotate on the first rotating shaft, outputting hot air from the ventilation pipe into the outer casing of the device to achieve a stable thermal environment. The starting motor output drives the second rotating shaft to rotate, which in turn drives the sprocket to rotate, which in turn drives the chain to move, achieving a synchronous transmission effect. The rotation of the sprocket drives the rotating roller to rotate, which in turn drives the rotating material tray to rotate, thus achieving efficient and uniform drying of the medicinal materials.
