Description

Technical Field

[0001] This utility model relates to a traditional Chinese medicine processing device, and more particularly to a device for drying Salvia miltiorrhiza. Background Technology

[0002] Traditional Chinese medicine, as an important component of traditional Chinese medicine, has been widely used to treat various diseases since ancient times. Danshen (Salvia miltiorrhiza) has a cultivation history of 200-300 years in China. Danshen from Sichuan, China, has a small head and thick branches, and the "Identification of Drug Production" records that Danshen from Pingwu County, Sichuan, is of the best quality. Danshen has the effects of promoting blood circulation and removing blood stasis, regulating menstruation and relieving pain, and calming the mind and relieving irritability. It is mainly used to treat women's menstrual disorders, postpartum abdominal pain due to blood stasis, injuries from falls, and restlessness.

[0003] However, in rural areas, after harvesting Salvia miltiorrhiza, farmers typically remove the mud and sand and pull off the fibrous roots by hand, then air-dry or kiln-dry it themselves. This process is labor-intensive, inefficient, and the quality of the processed Salvia miltiorrhiza is inconsistent due to varying skill levels and temperature differences in different kilns. When cooperatives or Salvia miltiorrhiza production bases collect the farmers' Salvia miltiorrhiza, they cannot guarantee the uniformity of quality. Therefore, it is necessary to design a Salvia miltiorrhiza kiln-drying device for cooperatives or production bases to process large quantities of Salvia miltiorrhiza centrally, eliminating the need for farmers to process it themselves. This would reduce farmers' workload while ensuring the quality of the Salvia miltiorrhiza. Utility Model Content

[0004] This utility model provides a device for drying Salvia miltiorrhiza, which features high automation, high efficiency, and stable quality of the processed Salvia miltiorrhiza. The specific technical solution is as follows:

[0005] A Danshen (Salvia miltiorrhiza) drying device includes a kang (earthen bed) and a combustion chamber. A horizontal smoke baffle is installed at the middle of the vertical direction inside the kang, dividing the interior into an upper smoke circulation zone and a lower smoke circulation zone. The upper and lower smoke circulation zones have exhaust ports and smoke inlets on the same side, respectively. A smoke channel is provided at the end of the horizontal smoke baffle away from the exhaust and smoke inlets to connect the upper and lower smoke circulation zones. The combustion chamber includes a combustion zone and a smoke exhaust zone. The combustion zone is connected to the smoke inlet, and the smoke exhaust zone is connected to the exhaust port. The combustion zone burns fuel to generate high-temperature smoke. The high-temperature smoke enters the lower smoke circulation zone through the smoke inlet, then enters the upper smoke circulation zone, and finally enters the smoke exhaust zone through the exhaust port. The top of the smoke exhaust zone is connected to an exhaust pipe, which discharges the smoke outside the Danshen processing plant.

[0006] Furthermore, the smoke channel of the horizontal smoke baffle is located in the middle of the rear side, and a diversion component is installed in the middle of the lower smoke circulation area. The diversion component can divert the high-temperature smoke entering from the smoke inlet, so that the high-temperature smoke flows on the left and right sides and then enters the upper smoke circulation area through the smoke channel in the middle of the rear side.

[0007] Furthermore, an arc-shaped guide hood is installed near the exhaust port in the upper smoke circulation zone. The guide hood allows the high-temperature smoke to enter the exhaust port from both the left and right sides.

[0008] Furthermore, a heat-conducting seat is installed at the top of the upper smoke circulation zone, and fins are installed on the heat-conducting seat. Soil is evenly spread above the heat-conducting seat, and the fins are inserted into the soil to form a kang surface.

[0009] Furthermore, the combustion zone is formed by a placement grille on the bottom surface, and heat insulation plates on the left and right sides and the top surface. A ventilation zone is provided below the placement grille, which can provide oxygen to the combustion zone.

[0010] Furthermore, the combustion zone also includes a furnace door that can be opened and closed.

[0011] Furthermore, an ash discharge drawer is inserted into the ventilation zone, which can receive the ash produced in the combustion zone.

[0012] Furthermore, a rack is installed above the kang (heated brick bed) to hold a transfer basket, so that the dried danshen slices can be directly loaded into the transfer basket.

[0013] Furthermore, multiple connecting columns are evenly distributed below the placement rack, and temperature sensors are installed on the connecting columns. A display screen is installed on the combustion cabinet, which can receive the detection signals from the temperature sensors and thus display the temperature of different positions on the kang surface in real time.

[0014] This invention provides a highly efficient and low-cost danshen (Salvia miltiorrhiza) drying device suitable for rural construction, enabling cooperatives or danshen production bases to process large quantities of danshen centrally. By controlling the flow position and direction of the flue gas, this invention effectively ensures the uniformity of the overall temperature on the drying surface, resulting in stable quality of the processed danshen. Furthermore, since the drying process is lengthy, multiple drying devices can be installed side-by-side, preventing the inability to process danshen due to the occupancy or damage of a single device.

[0015] The above description is merely an overview of the technical solution of this utility model. In order to better understand the technical means of this utility model and to implement it in accordance with the contents of the specification, and to make the above and other objects, features and advantages of this utility model more obvious and understandable, specific embodiments of this utility model are given below.

[0023] To better understand the purpose, function, and specific design of this utility model, the following detailed description of the Salvia miltiorrhiza drying device is provided in conjunction with the accompanying drawings.

[0024] like Figure 1-6 As shown, the Salvia miltiorrhiza drying device of this utility model includes a kang (heated brick bed) 1 and a combustion chamber 2. A horizontal smoke baffle 11 is provided at the middle position of the vertical direction inside the kang 1, dividing the interior of the kang 1 into an upper smoke circulation zone 12 and a lower smoke circulation zone 13. The upper smoke circulation zone 12 and the lower smoke circulation zone 13 are respectively provided with a smoke exhaust port 14 and a smoke inlet port 15 on the same side. A smoke channel 16 is provided at the end of the horizontal smoke baffle 11 away from the smoke exhaust port 14 and the smoke inlet port 15 to connect the upper smoke circulation zone 12 and the lower smoke circulation zone 13. The combustion chamber 2 includes a combustion zone 21 and a smoke exhaust zone 22. The combustion zone 21 is connected to the smoke inlet 15, and the smoke exhaust zone 22 is connected to the smoke exhaust outlet 14. The combustion zone 21 can burn fuels such as firewood and biomass pellets to produce high-temperature smoke. The high-temperature smoke enters the lower smoke circulation zone 13 through the smoke inlet 15, then enters the upper smoke circulation zone 12, and finally enters the smoke exhaust zone 22 through the smoke exhaust outlet 14. The top of the smoke exhaust zone 22 is connected to the smoke exhaust pipe, which can discharge the smoke to the outside of the Salvia miltiorrhiza treatment plant.

[0025] Specifically, in this embodiment, the side of the earthen bed 1 closest to the combustion chamber 2 is defined as the front side, and the side of the earthen bed 1 furthest from the combustion chamber 2 is defined as the rear side. Since the high-temperature smoke first flows from the front side of the lower smoke circulation zone 13 to the rear side, and then flows from the rear side of the upper smoke circulation zone 12 to the front side, the flow distance of the high-temperature smoke is effectively increased and the temperature uniformity of the front and rear sides of the earthen bed 1 is improved, and the temperature difference between the front and rear sides of the earthen bed 1 is reduced.

[0026] Preferred, such as Figure 4-5 As shown, in order to further improve the overall temperature uniformity of the kang surface 5 of the earthen kang 1 and avoid the lower temperature on the left and right sides of the kang surface 5, the smoke channel 16 of the horizontal smoke baffle 11 in this embodiment is located at the middle position of the rear side, and a diversion component 17 is provided at the middle position of the lower smoke circulation area 13. The diversion component 17 can divert the high-temperature smoke entering from the smoke inlet 15, so that the high-temperature smoke flows on the left and right sides and then enters the upper smoke circulation area 12 through the smoke channel 16 at the middle position of the rear side. An arc-shaped guide hood 18 is provided at the position of the upper smoke circulation area 12 near the smoke outlet 14. The guide hood 18 can allow the high-temperature smoke to enter the smoke outlet 14 from the left and right sides of the smoke outlet 14, so as to avoid the situation that the temperature in the middle of the kang surface 5 of the earthen kang 1 is too high, thereby further improving the overall temperature uniformity of the kang surface 5 of the earthen kang 1.

[0027] like Figure 6 As shown, in this embodiment, a heat-conducting seat 3 is provided at the top of the upper smoke circulation zone 12, and fins 31 are provided on the heat-conducting seat 3. Soil 4 is evenly spread above the heat-conducting seat 3, and the fins 31 are inserted into the soil 4 to form the kang surface 5. The kang surface 5 configured in this way has good thermal conductivity, heats up faster, and also further improves the uniformity of the overall temperature of the kang surface 5.

[0028] like Figure 1 and Figure 3 As shown, the combustion zone 21 in this embodiment includes a bottom grid 23 and is surrounded by heat insulation plates on the left and right sides and the top. A ventilation zone is provided below the grid 23 to provide oxygen to the combustion zone 21, thereby promoting combustion. Preferably, the ventilation zone is connected to a fan, which can increase the oxygen content in the combustion zone 21, thereby accelerating the generation of high-temperature flue gas. It is worth noting that the combustion zone 21 also includes a furnace door 24 that can be opened and closed. Closing the furnace door 24 can prevent the leakage of high-temperature smoke.

[0029] Preferably, in this embodiment, an ash discharge drawer 25 is inserted into the ventilation zone, and the ash discharge drawer 25 can receive the ash produced by the combustion zone 21.

[0030] It is worth noting that a placement rack 6 is provided above the kang surface 5. The placement rack 6 can hold a transfer basket, so that the dried danshen slices can be directly put into the transfer basket, preventing the danshen slices from falling to the ground when loading the basket. Preferably, multiple connecting columns are evenly distributed below the placement rack 6, and temperature sensors are installed on the connecting columns. A display screen is provided on the combustion cabinet 2. The display screen can receive the detection signals from the temperature sensors and thus display the temperature of different positions on the kang surface 5 in real time. This setting can ensure that the temperature difference between different positions on the kang surface 5 is within a certain range, and can also detect whether there is any damage to the kang body 1, so as to carry out timely repairs.

[0031] In this embodiment, multiple drying devices 6 can be arranged side by side to improve the drying efficiency of Salvia miltiorrhiza. Drying Salvia miltiorrhiza using a kang (heated brick bed) is low-cost, requiring only the burning of firewood and eliminating the need for electric heating, making it particularly suitable for rural use. In addition, the temperature of the kang surface 5 is stable, and the earthen kang surface 1 also has a moisture-absorbing effect, thereby improving the drying efficiency of Salvia miltiorrhiza.

[0032] This invention provides a highly efficient and low-cost danshen (Salvia miltiorrhiza) drying device suitable for rural construction, enabling cooperatives or danshen production bases to process large quantities of danshen centrally. By controlling the flow position and direction of the flue gas, this invention effectively ensures the uniformity of the overall temperature on the drying surface, resulting in stable quality of the processed danshen. Furthermore, since the drying process is lengthy, multiple drying devices can be installed side-by-side, preventing the inability to process danshen due to the occupancy or damage of a single device.

[0033] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
