Description

Technical Field

[0001] This application relates to the field of kudzu root powder production technology, and specifically discloses a drying device for kudzu root powder production. Background Technology

[0002] Kudzu root powder is a starch product made from kudzu root through a series of processing steps. After initial treatments such as washing, crushing, and grinding, kudzu root contains a large amount of moisture. If this moisture is not removed in time, it will easily lead to microbial growth during storage, causing mold and spoilage, affecting product quality and shortening shelf life. Drying can reduce the moisture content of kudzu root powder, making it meet the standards for safe storage and extending the product's shelf life.

[0003] Currently, most methods for drying kudzu root involve using drying racks. The crushed kudzu root is placed inside the rack, and hot air circulation is used to dry it. This method is static, the kudzu root is in a relatively fixed position, and the surface of the kudzu root in contact with the hot air is relatively uniform. Furthermore, some surfaces of the kudzu root are in contact with the drying rack or with each other, which can easily lead to drying dead zones. It also makes it difficult to inspect the kudzu root during the drying process, usually requiring machine shutdown for testing, thus affecting the normal drying process and reducing the efficiency of drying kudzu root. Therefore, this invention provides a drying device for kudzu root powder production to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to solve the problem that traditional drying devices, which use static drying, are prone to creating drying dead zones during the drying process.

[0005] To achieve the above objectives, the basic solution of this utility model provides a drying device for kudzu root powder production, comprising:

[0006] The drying drum has a feed pipe at the top and a discharge trough at the bottom.

[0007] The air supply assembly includes a hot air blower, an air supply duct located between the hot air blower and the bottom of the side wall of the drying cylinder, and several exhaust vents located at the top of the drying cylinder.

[0008] The circulation assembly includes a circulation chamber located on the side wall of the drying cylinder and connected to the bottom of the discharge chute, a conveyor belt located inside the circulation chamber, several scrapers located on the conveyor belt and scraping along the inner wall of the circulation chamber, and a circulation pipe located on the top side wall of the circulation chamber and connected to the top of the drying cylinder. The bottom of the circulation chamber is hinged with a cover plate.

[0009] The principle and effect of this basic scheme are as follows:

[0010] Compared with existing technologies, this invention, by setting up a circulation component, allows the kudzu root to flow back and forth in the drying drum and circulation chamber, thereby promoting the interaction between the kudzu root and the hot air, avoiding drying dead zones. At the same time, it can also detect the state of the kudzu root being dried without stopping the entire device to determine whether the drying standard has been met. This effectively solves the problems of drying dead zones caused by static drying in traditional drying devices and the problem of reduced drying efficiency due to the need to stop the machine for inspection.

[0011] Furthermore, the air supply assembly also includes an air supply hood disposed inside the drying drum, the air supply pipe being connected to the bottom of the air supply hood, and the air supply hood having several ventilation holes. The air supply hood allows for a more uniform distribution of hot air within the drying drum.

[0012] Furthermore, the air supply hood is rotatably connected to the drying cylinder, and a bracket supporting the air supply hood is provided inside the drying cylinder. A support shaft is provided between the air supply hood and the bracket, and several fan blades are provided on the support shaft. This arrangement further makes the hot air distribution more uniform inside the drying cylinder and avoids the accumulation of kudzu roots on the top of the air supply hood.

[0013] Furthermore, the sidewall of the air supply hood is evenly provided with several blades that move along the inner wall of the drying cylinder. This moves the material inside the drying cylinder, preventing kudzu root from accumulating at the edge of the inner wall of the drying cylinder.

[0014] Furthermore, the cover plate and the circulation chamber close to form an arc-shaped surface that adapts to the bottom of the scraper's moving path, and a lever is provided at the hinge point between the cover plate and the circulation chamber. The lever rotates the cover plate, causing it to close to facilitate the circulation of kudzu roots, or to open to discharge the dried kudzu roots.

[0015] Furthermore, a spring is provided between the lever and the side wall of the circulation chamber, or a torsion spring is provided at the hinge point between the cover and the circulation chamber, so that the cover is in a closed state under normal conditions.

[0016] Furthermore, the side wall of the circulation chamber is equipped with a transfer hopper that communicates with the interior of the circulation chamber and is located below the discharge chute. This facilitates the monitoring of the state of the kudzu roots being dried to determine whether they have met the drying standards. Attached Figure Description

[0023] A drying device for kudzu root powder production, implementing, for example Figure 1 As shown: It includes a drying cylinder 2 for drying kudzu roots, an air supply component for supplying hot air into the drying cylinder 2, and a circulation component for driving the kudzu roots to circulate.

[0024] Drying cylinder 2: The top of the drying cylinder 2 is equipped with a feed pipe 4, and the bottom of the drying cylinder 2 is equipped with a discharge trough 6.

[0025] Air supply assembly: includes a hot air blower 1, an air supply duct located between the hot air blower 1 and the bottom of the side wall of the drying cylinder 2, several exhaust vents located at the top of the drying cylinder 2, and an air supply hood 8 located inside the drying cylinder 2, such as... Figure 2 As shown, the air supply hood 8 is provided with several ventilation holes. The air supply hood 8 is rotatably connected to the drying cylinder 2. The drying cylinder 2 is provided with a support bracket for the air supply hood 8. A support shaft is provided between the air supply hood 8 and the support bracket. Several fan blades are provided on the support shaft. The air supply pipe is connected to the bottom of the air supply hood 8 and is directly opposite the fan blades on the support shaft. Thus, when hot air enters the drying cylinder 2, it blows the fan blades to drive the support shaft and the air supply hood 8 to rotate as a whole. Several paddles 9 are evenly provided on the side wall of the air supply hood 8, which move along the inner wall of the drying cylinder 2. During the rotation of the air supply hood 8, the paddles 9 play a moving role on the material in the drying cylinder 2, preventing kudzu root from accumulating at the edge of the inner wall of the drying cylinder 2.

[0026] The circulation assembly includes a circulation chamber 3 located on the side wall of the drying cylinder 2 and connected to the bottom of the discharge chute 6; a conveyor belt located inside the circulation chamber 3; several scrapers 12 mounted on the conveyor belt and scraping along the inner wall of the circulation chamber 3; and a circulation pipe 5 located on the top side wall of the circulation chamber 3 and connected to the top of the drying cylinder 2. The conveyor belt includes a motor, a pulley shaft 10 rotatably connected to the circulation chamber 3 and driven by the motor, pulleys mounted on the pulley shaft 10, and a belt 11 tensioned between the pulleys. The side wall of the circulation chamber 3 has a transfer hopper 7 that communicates with the interior of the circulation chamber 3 and is located below the discharge chute 6, facilitating the monitoring of the state of the dried kudzu roots to determine whether they meet the drying standards. Figure 3 As shown, a cover plate 13 is hinged to the bottom of the circulation chamber 3. The cover plate 13 and the circulation chamber 3 are closed to form an arc-shaped surface that is compatible with the bottom of the scraper 12's movement path. A lever 14 is provided at the hinge of the cover plate 13 and the circulation chamber 3. In order to keep the cover plate 13 in a closed state under normal conditions so as to provide an environment for kudzu circulation, a spring is provided between the lever 14 and the side wall of the circulation chamber 3, or a torsion spring is provided at the hinge of the cover plate 13 and the circulation chamber 3.

[0027] In this embodiment, by installing a conveyor belt and scraper 12 inside the circulation chamber 3, the kudzu roots entering the circulation chamber 3 are driven by the conveyor belt and scraper 12 and then fed into the drying cylinder 2 through the circulation pipe 5 at the top of the circulation chamber 3. This achieves the purpose of the kudzu roots flowing back and forth within the drying cylinder 2 and the circulation chamber 3, promoting the interaction between the kudzu roots and the hot air. At the same time, the air supply hood 8 ensures that the hot air is distributed more evenly within the drying cylinder 2, thus avoiding drying dead zones. The transfer bucket 7 can detect the state of the kudzu roots being dried without stopping the entire device to determine whether the drying standard has been met. This effectively solves the problems of drying dead zones caused by static drying in traditional drying devices and the problem of reduced drying efficiency due to the need to stop the machine for inspection.
