Abstract
Description
Technical Field
[0001] This utility model relates to the field of tea processing technology, and in particular to a dynamic dehydration and drying machine for tea. Background Technology
[0002] In tea processing, dehydration and drying are crucial steps that directly affect the quality and taste of the tea. Traditional tea dehydration and drying equipment often has several shortcomings. For example, many machines use static drying methods, causing the tea leaves to pile up during the drying process, resulting in uneven heating. Some leaves are over-dried, while others are under-dried, affecting the overall quality of the tea. Furthermore, the drying process generates waste such as tea leaves fragments. If these wastes are not collected and disposed of promptly, they can not only affect the normal operation of the equipment but may also mix into the tea, affecting its purity.
[0003] Therefore, it is extremely important to provide a dryer that can dynamically dehydrate and facilitate the separation of tea leaves and waste. Utility Model Content
[0004] The purpose of this invention is to provide a dynamic dehydration and drying machine for tea, which can significantly improve drying efficiency through dynamic dehydration, and can also separate waste and tea leaves during the dynamic drying process, thereby improving the purity of the tea.
[0005] The objective of this utility model is achieved through the following technical solution:
[0006] A dynamic dehydration and drying machine for tea includes a shell, a vertical vibration component for materials, and a heating component. The top of the shell is provided with a top cover, and the bottom of the shell is provided with a first discharge port. A first sealing component is provided inside the first discharge port, and the top cover is provided with a plurality of first exhaust holes.
[0007] The material vertical vibration assembly includes a housing disposed within the shell, a cover disposed at the top of the housing, a second discharge port disposed at the bottom of the housing, a second sealing assembly disposed at the second discharge port, and a vibration assembly disposed on the shell for driving the housing to perform vertical vibration; the cover is provided with a plurality of second exhaust holes;
[0008] The heating assembly includes multiple hot air blowers mounted on the housing, a first air duct mounted at the air outlet of the hot air blowers, a waste collection box mounted at the air outlet of the first air duct and located on the bottom wall of the housing, and a second air duct mounted between the waste collection box and the bottom wall of the housing; the second air duct is a telescopic tube.
[0009] Preferably, the vibration assembly includes a vertical slide groove disposed on the inner wall of the housing, a slider disposed on the outer wall of the housing and slidably connected to the vertical slide groove, a spring and a telescopic tube disposed between the bottom end of the slider and the bottom wall of the vertical slide groove, a rotating shaft horizontally disposed within the housing, an eccentric wheel sleeved on the outside of the rotating shaft, and a motor disposed on the outer wall of the housing and fixedly connected to the rotating shaft; the telescopic tube is sleeved on the outside of the spring.
[0010] Preferably, the bottom wall of the waste collection box extends to the outer wall of the housing and is provided with a bottom cover.
[0011] Preferably, the bottom wall of the box is inclined downward along the direction of the second discharge port; the bottom wall of the shell is inclined downward along the direction of the first discharge port.
[0012] Preferably, the first sealing component is selected from a piston and a blocking plate; the second sealing component is selected from a blocking plate, and the blocking plate and the second discharge port are threadedly connected; the bottom end of the blocking plate extends to the bottom of the second discharge port.
[0013] Preferably, the outer wall of the blocking plate located outside the second discharge port is provided with anti-slip texture.
[0014] Preferably, the second duct is a glass fiber silicone duct reinforced with steel wire.
[0015] Preferably, the air outlet end of the second air duct is provided with a trumpet-shaped air duct.
[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0017] This invention incorporates a vertical vibration component for the material, causing the drying chamber to vibrate vertically during the drying process. This continuous tumbling of the tea leaves within the chamber prevents uneven heating caused by tea leaf accumulation, allowing the tea leaves to fully receive the heat from the hot air and significantly improving the uniformity of tea leaf dehydration and drying.
[0018] Multiple hot air blowers in the heating assembly operate simultaneously, providing ample hot air to the chamber. This hot air is delivered directly into the chamber through a second duct, ensuring thorough contact with the tea leaves and accelerating moisture evaporation. Simultaneously, the vibration and agitation of the tea leaves further speeds up moisture dissipation, effectively improving drying efficiency.
[0019] The waste collection box in the heating assembly is located on the bottom wall of the housing, at the air inlet of the second air duct. Waste materials such as tea leaves generated during vibration fall into the waste collection box along the second air duct, facilitating their collection and preventing them from falling into the air ducts of the first and second air ducts, causing blockages, or being blown back into the box during the next tea drying process, thus affecting the purity of the tea. Furthermore, by incorporating a first discharge port and a first sealing component, waste materials falling during the dynamic drying process can be collected, thereby achieving complete collection of all waste materials separated during the entire dynamic drying process.
[0020] By defining the second air duct as a telescopic tube, it can adapt to the vertical movement of the chamber when the chamber vibrates vertically, ensuring stable hot air delivery and preventing the heating effect from being affected by the chamber vibration. The structural design is very reasonable and has strong adaptability. Attached Figure Description

Detailed Implementation
[0025] Example 1
[0026] A dynamic dehydration and drying machine for tea, such as Figure 1 As shown, the device includes a housing 1, a vertical vibration assembly for materials, and a heating assembly. A top cover 2 is provided at the top of the housing 1, and a first discharge port is provided at the bottom of the housing 1. A first sealing assembly 3 is provided inside the first discharge port, and multiple first vent holes are provided on the top cover 2. Figures 1-3 As shown, the first and second discharge ports are not located at the center of the bottom wall of the housing 1 and the box 4 to avoid conflict with the structure of the rotating shaft 15, which is located directly below the center of the bottom wall of the box 4. Support legs are provided at the four corners of the bottom wall of the housing 1, but are not shown in the figure.
[0027] like Figure 1 As shown, the material vertical vibration assembly includes a box 4 disposed inside the housing 1, a box cover 5 disposed at the top of the box 4, a second discharge port disposed at the bottom of the box 4, a second sealing assembly 6 disposed at the second discharge port, and a vibration assembly disposed on the housing 1 for driving the box 4 to perform vertical vibration; the box cover 5 is provided with multiple second exhaust holes; the bottom wall of the box 4 is provided with multiple waste holes so that small waste materials inside the box 4 can fall from the waste holes into the housing 1, thereby achieving the purpose of separating tea leaves and small waste materials.
[0028] like Figure 1 As shown, the heating assembly includes a plurality of hot air blowers 7 disposed on the housing 1, a first air duct 8 disposed at the air outlet end of the hot air blower 7, a waste collection box 9 disposed at the air outlet end of the first air duct 8 and located on the bottom wall of the housing 1, and a second air duct 10 disposed between the waste collection box 9 and the bottom wall of the housing 4; the second air duct 10 is a telescopic tube.
[0029] Furthermore, as shown in the figure and Figure 3 As shown, the vibration assembly includes a vertical slide groove 11 disposed on the inner wall of the housing 1, a slider 12 disposed on the outer wall of the housing 4 and slidably connected to the vertical slide groove 11, a spring and a telescopic tube disposed between the bottom end of the slider 12 and the bottom wall of the vertical slide groove 11, a rotating shaft 15 horizontally disposed in the housing 1, an eccentric wheel 16 sleeved on the outside of the rotating shaft 15, and a motor 17 disposed on the outer wall of the housing 1 and fixedly connected to the rotating shaft 15; the telescopic tube is sleeved on the outside of the spring (the spring is prior art and is not shown in the figure).
[0030] Furthermore, such as Figure 1 As shown, the bottom wall of the waste collection box 9 extends to the outer wall of the housing 1 and is provided with a bottom cover 18, wherein the bottom cover 18 and the waste collection box 9 can be threaded together to improve the convenience of installation and disassembly.
[0031] Working principle: First, open the top cover 2 and the box cover 5, and put the tea leaves to be dried into the box body 4. Then, close the box cover 5 and the top cover 2. The box cover 5 and the box body 4 are locked together using any locking structure in the existing technology to ensure synchronous vibration between the box cover 5 and the box body 4. Then, start the hot air blower 7. The hot air generated by the hot air blower 7 enters the waste collection box 9 through the first air duct 8, and then is transported to the box body 4 through the second air duct 10 to heat and dehydrate the tea leaves.
[0032] During the drying process, motor 17 is started, driving rotating shaft 15 to rotate. As it rotates, eccentric wheel 16 continuously strikes the chamber 4, causing slider 12 to move up and down within vertical groove 11, thus driving the chamber 4 to vibrate vertically. The tea leaves inside the chamber 4 are constantly turned over by the vibration, ensuring they fully contact the hot air and improving the uniformity and efficiency of dehydration and drying. During this process, the second air duct 10 continuously extends and retracts with the up-and-down movement of the chamber 4.
[0033] The moisture generated during the drying process is discharged outside the equipment through the second exhaust port on the lid 5 and the first exhaust port on the top cover 2. Some waste materials such as tea leaves fall into the bottom wall of the shell 1 through the waste material hole during vibration. At the same time, in the later stage of drying, heating is stopped and the residual heat is used for drying. During this period, the motor 17 needs to be started again to ensure that the waste materials in the tea leaves are fully separated from the tea leaves. During the separation process, some waste materials fall into the waste collection box 9 along the second air duct 10. Before the next batch of tea leaves is dried, the bottom cover 18 is opened to collect the waste materials that have fallen into the waste collection box 9. After the tea leaves are dried, the first sealing component 3 is opened to collect the waste materials that have fallen into the bottom wall of the shell 1. Then, the second sealing component 6 is removed by reaching into the first discharge port. The dried tea leaves fall into the shell 1 from the second discharge port. The first sealing component 3 is then opened again, and the tea leaves are discharged from the first discharge port, completing the entire dehydration and drying process.
[0034] Example 2
[0035] Based on Embodiment 1, the bottom wall of the housing 4 is inclined downwards along the direction of the second discharge port; the bottom wall of the shell 1 is inclined downwards along the direction of the first discharge port. This inclined design utilizes gravity to allow the tea leaves to be discharged more smoothly from the discharge port, reducing tea leaf residue in the equipment and facilitating subsequent operation and cleaning.
[0036] Furthermore, the first sealing component 3 is selected from a piston and a blocking plate; the second sealing component 6 is selected from a blocking plate, and the blocking plate and the second discharge port are threadedly connected; the bottom end of the blocking plate extends below the second discharge port. These sealing components have a simple structure and good sealing effect. The threaded connection of the blocking plate facilitates installation and disassembly, and can accurately control the discharge time and speed to meet different processing needs.
[0037] Furthermore, the outer wall of the blocking plate located outside the second discharge port is provided with anti-slip texture, which increases the friction between the hand and the blocking plate, making it easier and more convenient to turn the blocking plate, and making it easier for operators to operate.
[0038] Furthermore, the second duct 10 is a steel-wire reinforced glass fiber silicone duct. This type of duct has good flexibility and extensibility, which can well adapt to the vertical vibration of the housing 4. It also has the characteristics of high temperature resistance and corrosion resistance, which extends the service life of the duct and ensures the stable delivery of hot air.
[0039] Furthermore, such as Figure 1 As shown, the air outlet of the second air duct 10 is provided with a trumpet-shaped air duct 19. The trumpet-shaped design can disperse the hot air, making the hot air blow more evenly onto the tea leaves inside the chamber 4, further increasing the contact area between the hot air and the tea leaves, and enhancing the drying effect.
