Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of tea aroma extraction and coloration, and particularly relates to a tea aroma extraction and coloration integrated device. BACKGROUND

[0002] Tea, commonly known as tea, generally includes leaves and buds of tea trees. Tea contains ingredients such as catechin, cholestenone, caffeine, inositol, folic acid, and pantothenic acid, which are beneficial to health. Tea beverages made from tea are one of the world's three major beverages. The taste of tea determines the quality of the tea, so it is necessary to preserve the aroma of tea during tea processing to improve the taste of tea. The common method for extracting aroma is frying.

[0003] A patent with publication number CN120052434A discloses a tea aroma extraction and baking device. During operation, the ventilation pipe is tightly connected to the nut seat of the electric lead screw. Therefore, when the electric lead screw is working, the linear motion of the nut seat directly drives the ventilation pipe and the connected stirring mechanism (including the spike rake) to move back and forth in the tea tray. This moving method is not only accurate and controllable, but also ensures that the stirring mechanism always operates on the set track during the baking process. When it is necessary to discharge the baked tea, the operator can manually or through a mechanical device to push the bottom plate to rotate downward. With the rotation of the bottom plate, a discharge port is gradually formed between the bottom plate and the outer frame, and the tea can be smoothly discharged through the discharge port.

[0004] The above-mentioned scheme still has some problems in actual application. Generally, an appropriate amount of tea is poured into the drum of the aroma extraction machine, and then the drum is driven to rotate to stir and fry the tea, while water mist is sprayed inside the tea to ensure the humidity of the tea. After the aroma extraction and coloration of the tea are completed, the tea is poured and collected from the inner cavity of the drum, and then the next batch of tea aroma extraction and coloration processing is carried out. This operation method not only has low efficiency, but also the aroma extraction machine is fixed, the tea near the air outlet is high in temperature and dries quickly, and the tea far from the hot air outlet is low in temperature and dries slowly. In order to make the tea evenly heated, a stirring mechanism is needed to stir the baked material, which causes the damage of the tea leaves and the generation of debris, reducing the quality and economic benefit of the tea.

[0005] Therefore, the present application provides a tea aroma extraction and coloration integrated device. SUMMARY

[0006] In order to make up for the deficiencies of the prior art and solve at least one technical problem in the background art.

[0007] The technical scheme adopted by the present application to solve the technical problems is that the tea aroma extraction and coloration integrated device comprises a bracket, a fixed cylinder is installed in the inner cavity of the bracket, a clamp is installed on one side of the bracket through a hinge, and the clamp fastens the fixed cylinder in cooperation with the bracket, and a screening aroma extraction assembly is arranged in the inner cavity of the fixed cylinder. Furthermore, the sieving and aroma-enhancing component includes a sieving cylinder rotatably connected to the inner cavity of a fixed cylinder. The inner cavity of the sieving cylinder is provided with multiple sets of threaded paddles for conveying tea leaves. At the same time, the threaded paddles can stir-fry the tea leaves during the conveying process, so that they can be heated and cooled evenly, thereby improving the efficiency of tea leaf processing. The sieving cylinder is equipped with a threaded conveyor frame on the outside, and the threaded conveyor frame is in contact with the inner wall of the fixed cylinder to push the tea dregs and tea dust sieved out in the inner cavity of the fixed cylinder.

[0008] Preferably, a fixing block is fixedly connected to the outside of the screening cylinder, and an annular support frame is fixedly connected to the outside of the fixing block. A toothed ring is provided in the inner cavity of the annular support frame, and the fixing cylinder and the annular support frame are rotatably installed.

[0009] Preferably, the gear ring is externally connected to a gear plate, a servo motor is fixedly installed inside the gear plate, a first mounting bracket is fixedly connected to the outside of the servo motor, a base is fixedly connected to the lower end of the first mounting bracket, and the base is fixedly installed with the bracket.

[0010] Preferably, a discharge port is provided at one end of the fixed cylinder, and a slag discharge port is provided at the other end of the fixed cylinder located outside the discharge port.

[0011] Preferably, a second mounting bracket is fixedly installed on one side of the inner cavity of the screening cylinder, and a spray pipe is fixedly connected inside the second mounting bracket. The lower end of the spray pipe has an atomizing spray hole, and one end of the spray pipe is rotatably connected to the fixed cylinder.

[0012] Preferably, one end of the fixed cylinder is fixedly connected to a water guide pipe, and the water guide pipe is fixedly connected to the spray pipe. The spray pipe is threaded on the outside, and an annular cleaning frame is threadedly connected to the outside of the spray pipe.

[0013] Preferably, the spray pipe is rotatably connected to a rotating frame, the rotating frame is fixedly connected to two ends of a fixed column, one end of a fixed column is fixedly connected to a bracket, and the annular cleaning frame is slidably connected to the fixed column.

[0014] Preferably, an annular fixing frame is fixedly installed on the upper end of the base, the annular fixing frame is rotatably connected to the fixing cylinder, a bracket is fixedly installed on the inner wall of the annular fixing frame, and a funnel is provided on the upper end of the annular fixing frame.

[0015] Preferably, an installation cover is fixedly installed at one end of the annular fixing frame, a blower is provided inside the installation cover, and an electric heater is provided inside the installation cover.

[0016] The beneficial effects of this invention are as follows: 1. The integrated tea aroma-enhancing and color-enhancing device of the present invention uses a servo motor to drive a geared disc to rotate. The geared disc then meshes with a transmission gear ring to drive a ring support frame to rotate. When the ring support frame rotates, it works in conjunction with a fixed block to drive a sieve cylinder to rotate synchronously. This causes the sieve cylinder to roll and convey tea leaves through threaded paddles. As the tea leaves are rolled and conveyed by the threaded paddles, they continuously fall from the inner wall of the sieve cylinder to the bottom of its inner cavity, thus achieving a stir-frying effect. This allows the tea leaves to be heated evenly and quickly dissipates the moisture generated by the heat. At the same time, tea dregs and tea dust in the tea leaves are separated through the mesh of the sieve cylinder and enter the inner cavity of the fixed cylinder, effectively improving the quality of the tea leaves. In addition, the rotation of the sieve cylinder also drives the threaded conveyor frame to rotate. The threaded conveyor frame scrapes and conveys the tea dregs and tea dust in the inner cavity of the fixed cylinder, which are then discharged and collected through the dregs outlet at the bottom of the fixed cylinder. The tea leaves are discharged and collected through the discharge outlet at one end of the fixed cylinder. Through this series of operations, the tea leaves can be circulated and stir-fried to enhance aroma and color, improving the efficiency of tea aroma and color enhancement.

[0017] 2. The integrated tea aroma-enhancing and color-enhancing device of the present invention uses a sieving cylinder to drive a second mounting frame to rotate, which in turn drives a spray pipe to rotate. During the rotation of the spray pipe, a threaded annular cleaning frame moves outside the fixed column. The inner wall of the annular cleaning frame is uniformly equipped with wire brushes, which can clean the spray holes of the spray pipe. This prevents tea dust and dregs generated during the rolling conveying of tea leaves from adhering to the spray holes of the spray pipe, thus affecting the steam spraying efficiency. When tea leaves are put into the inner cavity of the sieving cylinder, the electric heater and blower are activated. The blower draws external air into the annular fixed frame, and the electric heater heats the air to generate hot air. The blower then blows the hot air into the sieving cylinder to dry and enhance the aroma of the tea leaves. Attached Figure Description

[0020] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0021] Example 1, as Figures 1 to 3 As shown, the tea aroma-enhancing and color-enhancing integrated device of the present invention includes a bracket 2, a fixed cylinder 4 installed in the inner cavity of the bracket 2, a clamp 3 installed on one side of the bracket 2 by a hinge, and the clamp 3 cooperates with the bracket 2 to fasten the fixed cylinder 4. A sieving aroma-enhancing component 8 is provided in the inner cavity of the fixed cylinder 4. Furthermore, the sieving and aroma-enhancing component 8 includes a sieving cylinder 81 rotatably connected to the inner cavity of the fixed cylinder 4. The inner cavity of the sieving cylinder 81 is provided with multiple sets of threaded paddles 85 for conveying tea leaves. At the same time, the threaded paddles 85 can stir-fry the tea leaves during the conveying process, so that they can be heated and cooled evenly, thereby improving the efficiency of tea leaf processing. A threaded conveyor frame 84 is provided on the outside of the screening cylinder 81, and the threaded conveyor frame 84 is in contact with the inner wall of the fixed cylinder 4, which is used to push the tea dregs and tea dust screened out in the inner cavity of the fixed cylinder 4 for collection.

[0022] Specifically, in existing technology, a suitable amount of tea leaves are usually put into the drum of the coloring machine, and then the drum is driven to rotate, causing the tea leaves to be stir-fried. At the same time, water mist is sprayed inside the tea leaves to ensure the humidity of the tea leaves. After the coloring and aroma enhancement of the tea leaves are completed, the tea leaves are poured out of the inner cavity of the drum and collected, and then the next batch of tea leaves is processed for coloring and aroma enhancement. This operation method is not only inefficient, but the tea leaves after coloring and aroma enhancement also need to be screened, which affects the efficiency of tea production and processing.

[0023] In the process of enhancing the aroma and color of tea, this invention involves feeding tea leaves into the inner cavity of a sieving cylinder 81 and simultaneously driving the sieving cylinder 81 to rotate clockwise. The sieving cylinder 81 then uses a threaded paddle 85 to agitate and transport the tea leaves. When the tea leaves have rolled halfway through the sieving cylinder 81 with the paddle 85, they fall from the inner wall of the sieving cylinder 81 to the bottom of the inner cavity, thus achieving a tumbling process. This allows the tea leaves to be heated evenly and the moisture generated during heating to dissipate quickly, improving the efficiency of enhancing the aroma and color of the tea. Furthermore, during the rolling transport of the tea leaves through the sieving cylinder 81, the mesh of the sieving cylinder 81 can separate out tea dregs and tea dust, thereby improving the quality of the tea and solving the aforementioned problems.

[0024] like Figure 1 , Figure 3 and Figure 4 As shown, a fixed block 82 is fixedly connected to the outside of the screening cylinder 81, and an annular support frame 83 is fixedly connected to the outside of the fixed block 82. A toothed ring 86 is provided in the inner cavity of the annular support frame 83. The fixed cylinder 4 and the annular support frame 83 are rotatably installed. A toothed disc 11 is meshed with the outside of the toothed ring 86. A servo motor 10 is fixedly installed inside the toothed disc 11. A first mounting frame 9 is fixedly connected to the outside of the servo motor 10. A base 1 is fixedly connected to the lower end of the first mounting frame 9. The base 1 and the bracket 2 are fixedly installed. A discharge port 13 is opened at one end of the fixed cylinder 4, and a slag outlet 12 is opened at the other end of the fixed cylinder 4 located at the discharge port 13.

[0025] Specifically, during the coloring and aroma enhancement of tea leaves, the servo motor 10 is activated, driving the gear disc 11 to rotate. Simultaneously, the gear disc 11 meshes with the transmission gear ring 86, causing it to rotate, which in turn drives the annular support frame 83 to rotate. During this rotation, the annular support frame 83, in conjunction with the fixed block 82, drives the sieving cylinder 81 to rotate synchronously. This causes the sieving cylinder 81 to use threaded paddles 85 to agitate and transport the tea leaves. As the tea leaves are transported along with the threaded paddles 85, they continuously fall from the inner wall of the sieving cylinder 81 to the bottom of its inner cavity, achieving a stirring effect. This ensures the tea leaves are heated evenly while quickly dissipating the moisture generated during heating. Meanwhile, tea dregs and dust inside the tea leaves are separated through the mesh of the sieving cylinder 81 and enter the sieving cylinder. The tea leaves are processed in the inner cavity of the fixed cylinder 4, thereby effectively improving the quality of the tea. During the rotation of the screening cylinder 81, the screw conveyor 84 will also rotate, and the screw conveyor 84 will scrape the tea dregs and tea dust in the inner cavity of the fixed cylinder 4 for conveying. Then, they will be discharged and collected through the dregs outlet 12 at the lower end of the fixed cylinder 4, while the tea leaves will be discharged and collected through the discharge outlet 13 at one end of the fixed cylinder 4. This enables the tea leaves to be circulated for roasting, aroma enhancement, and color improvement, improving the efficiency of tea aroma enhancement and color improvement. This solves the problem that the existing integrated tea aroma enhancement and color improvement device is difficult to circulate for tea aroma enhancement and color improvement, resulting in low efficiency of tea aroma enhancement and color improvement. Moreover, during the tea aroma enhancement and color improvement process, the tea leaves are screened to remove internal tea dregs and tea dust, which requires subsequent screening of the tea leaves and reduces the production efficiency of tea.

[0026] Example 2, as Figures 4 to 6 As shown, a second mounting bracket 87 is fixedly installed on one side of the inner cavity of the screening cylinder 81. A spray pipe 88 is fixedly connected inside the second mounting bracket 87. An atomizing spray hole is opened at the lower end of the spray pipe 88. One end of the spray pipe 88 is rotatably connected to the fixed cylinder 4. One end of the fixed cylinder 4 is fixedly connected to a water guide pipe 813, and the water guide pipe 813 is fixedly connected to the spray pipe 88. The outside of the spray pipe 88 is threaded, and an annular cleaning frame 811 is threadedly connected to the outside of the spray pipe 88.

[0027] Specifically, during the rolling conveying of tea leaves in the screening cylinder 81, a steam pipe is connected to the water guide pipe 813, allowing steam to be discharged into the water guide pipe 813 and then into the spray pipe 88. The steam is then sprayed out through the spray pipe 88 to humidify the tea leaves, preventing them from becoming too dry during the frying process. This would prevent the tea leaves from becoming brittle and easily breaking during the rolling conveying process, thus affecting the quality of the tea leaves.

[0028] like Figures 4 to 6As shown, a rotating frame 810 is rotatably connected to the outside of the spray pipe 88. Fixed columns 89 are fixed to both ends of the rotating frame 810. A bracket 812 is fixed to one end of the fixed column 89. The annular cleaning frame 811 is slidably connected to the fixed column 89. An annular fixed frame 5 is fixedly installed on the upper end of the base 1. The annular fixed frame 5 is rotatably connected to the fixed cylinder 4. The bracket 812 is fixedly installed on the inner wall of the annular fixed frame 5. A funnel 6 is provided on the upper end of the annular fixed frame 5. An installation cover 7 is fixedly installed on one end of the annular fixed frame 5. A blower 14 is provided in the inner cavity of the installation cover 7. An electric heater is provided in the inner cavity of the installation cover 7.

[0029] Specifically, during the rolling conveying of tea leaves, the screening cylinder 81 drives the second mounting frame 87 to rotate, which in turn drives the spray pipe 88 to rotate. As the spray pipe 88 rotates, it drives the annular cleaning frame 811, which moves outside the fixed column 89 via a threaded transmission. The inner wall of the annular cleaning frame 811 is evenly equipped with wire brushes, which clean the spray holes of the spray pipe 88. This prevents tea dust and dregs from adhering to the spray holes of the spray pipe 88 during the rolling conveying of tea leaves, thus affecting the steam spraying efficiency. When tea leaves are added into the inner cavity of the screening cylinder 81, the electric heater is activated. The blower 14 draws in external air into the annular fixed frame 5, while an electric heater heats the air to generate hot air. The hot air is then blown into the sieving cylinder 81 by the blower 14 to dry and enhance the aroma of the tea. This solves the problem that existing integrated tea aroma-enhancing and color-enhancing devices usually require spraying steam to humidify the tea during the rolling drying process. However, this process generates dust, and tea residue and dust easily adhere to the steam spray nozzles, causing blockage and hindering effective steam spraying. This, in turn, damages the leaf cell structure and reduces the quality of the tea.

[0030] Working principle: When processing tea leaves for color and aroma enhancement, the servo motor 10 is activated, driving the gear disc 11 to rotate. Simultaneously, the gear disc 11 meshes with the transmission gear ring 86, causing it to rotate, which in turn drives the annular support frame 83 to rotate. During rotation, the annular support frame 83, in conjunction with the fixed block 82, drives the sieving cylinder 81 to rotate synchronously. This causes the sieving cylinder 81 to use threaded paddles 85 to agitate and transport the tea leaves. As the tea leaves are transported along with the threaded paddles 85, they continuously fall from the inner wall of the sieving cylinder 81 to the bottom of its inner cavity, thus achieving a stirring effect. This allows the tea leaves to be heated evenly while quickly dissipating the moisture generated by the heat. The tea dregs and tea dust inside the tea leaves are separated through the mesh of the sieve cylinder 81 and enter the inner cavity of the fixed cylinder 4, thereby effectively improving the quality of the tea leaves. During the rotation of the sieve cylinder 81, it also drives the threaded conveyor frame 84 to rotate, and the threaded conveyor frame 84 scrapes the tea dregs and tea dust in the inner cavity of the fixed cylinder 4 for conveying. Then, the dregs are discharged and collected through the dregs outlet 12 at the lower end of the fixed cylinder 4, while the tea leaves are discharged and collected through the discharge outlet 13 at one end of the fixed cylinder 4. This enables the tea leaves to be circulated and roasted to enhance their aroma and color, thereby improving the efficiency of enhancing the aroma and color of the tea leaves. During the rolling conveying of tea leaves, the screening cylinder 81 drives the second mounting frame 87 to rotate, which in turn drives the spray pipe 88 to rotate. As the spray pipe 88 rotates, it drives the annular cleaning frame 811 to move outside the fixed column 89 via a threaded transmission. The inner wall of the annular cleaning frame 811 is evenly equipped with wire brushes, which can be used to clean the spray holes of the spray pipe 88. This prevents tea dust and dregs generated during the rolling conveying of tea leaves from adhering to the spray holes of the spray pipe 88, thus affecting the steam spraying efficiency. When tea leaves are put into the inner cavity of the screening cylinder 81, the electric heater and blower 14 are activated. The blower 14 draws outside air into the annular fixed frame 5, and the electric heater heats the air to generate hot air. The blower 14 then blows the hot air into the screening cylinder 81 to dry and enhance the aroma of the tea leaves.
