Abstract
Description
Technical Field
[0001] This utility model relates to the field of tea production technology, and in particular to a drying device for producing kudzu root tea. Background Technology
[0002] Kudzu root tea is a tea beverage made primarily from kudzu root. It is a traditional Chinese herbal tea. The main benefits of kudzu root tea include clearing heat and detoxifying, lowering blood pressure, antibacterial and anti-inflammatory properties, and it can also help prevent coronary heart disease and cerebrovascular diseases. Kudzu root tea is widely loved for its mellow taste and unique aroma.
[0003] In existing technologies, there are various production processes for kudzu root tea, such as: kudzu root washing → granulation → color protection → steaming (heating to inactivate enzymes and maintain the color of kudzu root) → drying → cooling. In this production process, the drying step can remove the moisture in the kudzu root to the greatest extent, so as to effectively improve the shelf life of kudzu root tea.
[0004] In existing technologies, the drying process is completed using a drying device. Specifically, the drying device generally includes a drying chamber and multiple placement plates distributed vertically within the drying chamber. Kudzu root pieces are directly laid flat on the placement plates for drying. Since the kudzu root remains stationary during drying, the drying methods in existing technologies are mostly static drying methods. This method can quickly dry kudzu root pieces with their surface fully exposed. However, it is difficult to quickly dry kudzu root pieces that are in contact with other kudzu root pieces or with the placement plates. This is because the parts in contact with the kudzu root pieces or the placement plates are non-exposed areas, and hot air cannot quickly reach these parts, which seriously affects the overall drying efficiency. Utility Model Content
[0005] The purpose of this utility model is to provide a drying device for kudzu root tea production, which uses vertical vibration during the drying process to make the kudzu root pieces vibrate, thereby exposing the parts of the kudzu root pieces that were originally in contact with other kudzu root pieces or the placement plate, so that the hot air dries the exposed areas and effectively improves the drying efficiency.
[0006] The objective of this utility model is achieved through the following technical solution:
[0007] A drying device for producing kudzu root tea includes a drying box, a door set on the side wall of the drying box, a hot air blower set on the bottom wall of the drying box, a support plate surrounding the inner wall of the drying box, a movable barrel set on the support plate via a telescopic component, multiple placement plates evenly distributed inside the movable barrel, and a vibration component for driving the movable barrel to vibrate vertically.
[0008] The edge of the placement plate is provided with a baffle;
[0009] The bottom wall and the side near the door of the mobile barrel are open. The top wall, side walls, placement plate and baffle of the mobile barrel are provided with multiple air holes. The top wall of the door is provided with multiple ventilation holes.
[0010] Preferably, the movable bucket has a bucket door on the side near the box door; when the bucket door is closed, it contacts the end of the placement plate near the box door, and the end of the placement plate away from the box door contacts the side of the movable bucket away from the box door; the bucket door is provided with a plurality of air holes.
[0011] Preferably, sliders are provided on both sides of the placement plate, and a horizontal groove is provided on the inner wall of the movable barrel to slide in cooperation with the sliders.
[0012] Preferably, the telescopic assembly includes multiple springs disposed between the support plate and the movable barrel, and a telescopic rod disposed within each of the springs.
[0013] Preferably, the vibration assembly includes a rotating shaft disposed inside the drying chamber, an eccentric wheel disposed on the rotating shaft, a motor disposed on the side wall of the drying chamber and connected to the end of the rotating shaft, and a connecting rod horizontally disposed at the bottom of the moving drum and located directly above the eccentric wheel.
[0014] Preferably, the top wall of the drying oven is connected to a dust collection hood, the air outlet of the dust collection hood is provided with a filter assembly, and the air outlet of the filter assembly is connected to an exhaust fan provided on the side wall of the drying oven.
[0015] Preferably, the filtration assembly includes a first air duct connected to the air outlet of the dust collection hood, a filter box connected to the air outlet of the first air duct and disposed on the outer wall of the drying oven, a filter screen horizontally disposed in the filter box, and a second air duct connected to the air outlet of the filter box, the second air duct being connected to the exhaust fan; the air outlet of the first air duct is disposed below the filter screen.
[0016] Preferably, the bottom end of the filter box is hinged with a bottom cover, the side wall of the filter box is horizontally provided with a limiting post capable of horizontal displacement, and the free end of the bottom cover is provided with a limiting hole adapted to the limiting post.
[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0018] By lining the inner wall of the drying oven with a support plate, and installing a movable barrel on the support plate via a telescopic assembly, multiple placement plates are evenly distributed vertically within the movable barrel, and a vibration assembly is installed to drive the movable barrel to vibrate vertically. After kudzu root pieces are placed on the placement plates, the vibration assembly causes the movable barrel to vibrate vertically within the drying oven, thereby causing the material inside the movable barrel to vibrate vertically. During the vibration process, the distance between the materials increases, facilitating the passage of hot air through the kudzu root pieces and improving drying efficiency. At the same time, it can also separate kudzu roots that were originally in contact with each other, and separate kudzu roots that were in contact with the placement plates from the placement plates, thereby increasing the exposed area of the kudzu root pieces, which in turn increases the contact between hot air and the exposed parts, improving drying efficiency.
[0019] By setting baffles at the edges of the placement plate, the pueraria lobata can be blocked, preventing some of the pueraria lobata from falling along the edges of the placement plate to the bottom wall of the drying oven during vibration.
[0020] Multiple air vents are provided on the top and side walls of the mobile drum, the placement plate, and the baffle, allowing hot air to pass through freely and improving the drying efficiency. Attached Figure Description

Detailed Implementation
[0026] Example 1
[0027] A drying device for kudzu root tea production, such as Figure 1-2As shown, the device includes a drying chamber 1, a door 2 hinged to the side wall of the drying chamber 1, a hot air blower 3 mounted on the bottom wall of the drying chamber 1, a support plate 4 surrounding the inner wall of the drying chamber 1, a movable barrel 5 mounted on the support plate 4 via a telescopic assembly, multiple placement plates 6 evenly distributed vertically within the movable barrel 5, and a vibration assembly for driving the movable barrel 5 to vibrate vertically; Figure 1 and Figure 3 As shown, the edge of the placement plate 6 is provided with a baffle 7; the bottom wall of the movable barrel 5 and the side near the box door 2 are open; the top wall and side wall of the movable barrel 5, the placement plate 6 and the baffle 7 are provided with multiple air holes (this is prior art and is not shown in the figure); the top wall of the box door 2 is provided with multiple ventilation holes (this is prior art and is not shown in the figure).
[0028] Furthermore, such as Figure 1 As shown, the telescopic assembly includes multiple springs 11 disposed between the support plate 4 and the movable barrel 5, and a telescopic rod disposed within each spring 11. Further, as... Figure 1 As shown, the vibration assembly includes a rotating shaft 12 disposed inside the drying chamber 1, an eccentric wheel 13 disposed on the rotating shaft 12, a motor 14 disposed on the side wall of the drying chamber 1 and connected to the end of the rotating shaft 12, and a connecting rod 21 horizontally disposed at the bottom of the moving barrel 5 and located directly above the eccentric wheel 13.
[0029] Working principle: Place the kudzu root pieces to be dried one by one on the top of the placement plate 6 and spread them flat. Then, close the box door 2 and turn on the hot air blower 3. The hot air blower 3 generates hot air and quickly enters the drying box 1 to dry the kudzu root pieces in the drying box 1. During the drying process, the water vapor is discharged through multiple vents.
[0030] After drying for a period of time, the motor 14 is turned on. Under the action of the motor 14, the rotating shaft 12 drives the eccentric wheel 13 to rotate. During the process of the eccentric wheel 13 contacting the bottom end of the connecting rod 21, it can drive the connecting rod 21 and the moving barrel 5 to vibrate vertically synchronously, thereby causing the material in the moving barrel 5 to vibrate vertically. During the vibration process, the distance between the materials increases, which facilitates the passage of hot air through the kudzu root pieces, improving the drying efficiency. At the same time, it can also separate the kudzu roots that were originally in contact with each other, and separate the kudzu roots that were in contact with the placement plate 6 from the placement plate 6, thereby increasing the exposure area of the kudzu root pieces, thereby increasing the contact between the hot air and the exposed parts, and improving the drying efficiency.
[0031] Example 2
[0032] In Example 1, because different materials have different weights, their vibration intensity varies. Even with baffle 7 installed, a small amount of material still falls over baffle 7 and onto the outside of the placement plate 6. Based on this, in addition to Example 1, as follows... Figure 2 As shown, the movable drum 5 has a drum door 8 on the side near the box door 2. When the drum door 8 is closed, it contacts the end of the placement plate 6 near the box door 2, and the end of the placement plate 6 away from the box door 2 contacts the side of the movable drum 5 away from the box door 2. This arrangement can limit the front (side near the drum door 8) and rear of the placement plate 6. The drum door 8 is provided with multiple air holes (existing technology, not shown in the figure). By limiting the front and rear positions of the placement plate 6 during drying, the drum door 8 and the rear of the movable drum 5 can block the front and rear sides of the placement plate 6, ensuring that the material will not fall over the baffle 7 and onto the outside of the placement plate 6 when vibrating. Furthermore, as... Figure 1-2 As shown, sliders 9 are provided on both sides of the placement plate 6, and a horizontal groove 10 is provided on the inner wall of the moving barrel 5 to slide in cooperation with the sliders 9. The sliders 9 and the horizontal groove 10 facilitate the disassembly and installation of the placement plate 6, improving the flexibility of the device. Furthermore, the sliders 9 and the horizontal groove 10 also limit the placement plate 6 within the moving barrel 5, preventing it from moving vertically relative to the moving barrel 5. In actual installation, the distance between the baffle 7 on the placement plate 6 and the inner wall of the moving barrel 5 with the horizontal groove 10 is extremely small to prevent the puerarin from falling over the baffle 7 and onto the outside of the placement plate 6.
[0033] Example 3
[0034] In Example 1 or Example 2, some fine dust generated during the vibration drying process will disperse within the drying chamber 1. If this dispersed dust is directly discharged into the environment through the vents, it will have an adverse impact on the environment. Therefore, based on Example 1 or 2, such as... Figure 4 As shown, a dust collection hood 15 is connected to the top wall of the drying chamber 1. A filter assembly is installed at the air outlet of the dust collection hood 15, and the air outlet of the filter assembly is connected to an exhaust fan 16 installed on the side wall of the drying chamber 1. Further, as... Figure 4As shown, the filtration assembly includes a first air duct connected to the air outlet of the dust collection hood 15, a filter box 17 connected to the air outlet of the first air duct and disposed on the outer wall of the drying oven 1, a filter screen 18 horizontally disposed within the filter box 17, and a second air duct connected to the air outlet of the filter box 17, the second air duct being connected to the exhaust fan 16; the air outlet of the first air duct is disposed below the filter screen 18, so that the material trapped by the filter screen 18 can fall to the bottom of the filter box 17 under the action of gravity. Furthermore, a bottom cover 19 is hinged to the bottom of the filter box 17, and a horizontally movable limiting post 20 is disposed on the side wall of the filter box 17, the free end of the bottom cover 19 having a limiting hole adapted to the limiting post 20.
[0035] Working principle: During the vibration drying process, the exhaust fan 16 is turned on. Under the action of the exhaust fan 16, the gas and dust in the drying chamber 1 are drawn into the filter chamber 17. After being filtered by the filter chamber 17, the dust is trapped inside the filter chamber 17, preventing it from polluting the environment. When it is necessary to remove the material from the filter chamber 17, the limiting post 20 is moved away from the bottom cover 19 to release the limiting position on the bottom cover 19. Then, the bottom cover 19 can be opened to remove the material.
[0036] In actual implementation, the ventilation hole is set within the vertical projection of the dust hood 15. The dust hood 15 and the first air duct (hose) are threaded together. Generally speaking, when the vibration component is not used, the exhaust fan 16 does not need to be turned on. At this time, the first air duct and the dust hood 15 need to be separated, and then reconnected when the exhaust fan 16 is used.
