Abstract
Description
Technical Field
[0001] This utility model relates to the field of white tea processing technology, and in particular to a shaking device for white tea processing. Background Technology
[0002] The shaking process in white tea processing is one of the important steps in the tea-making process. The purpose is to promote the activation of enzymes inside the tea leaves through slight collision and friction, so that the tea leaves undergo moderate oxidation, thereby forming a unique aroma and taste.
[0003] Early shaking devices were mostly simple rotating drums or shaking tables, lacking a dedicated ventilation system. During the shaking process, the tea leaves are constantly turned over, and their respiration causes the carbon dioxide concentration inside the device to increase while the oxygen content decreases. At the same time, the evaporation of moisture from the tea leaves causes the internal humidity to increase rapidly. If ventilation is not timely, excessive humidity can easily lead to mold growth on the tea leaves, affecting their quality. Moreover, the heat accumulated in the enclosed environment causes the tea leaves to become too hot, accelerating the oxidation process and leading to over-fermentation, which significantly diminishes the aroma and taste.
[0004] Furthermore, some shaking devices with ventilation designs employ a relatively simple ventilation method, with only a few vents on the side or top of the device, relying on natural ventilation to regulate the internal environment. However, natural ventilation is greatly affected by external environmental factors such as wind force, wind direction, and temperature, making it difficult to precisely control the ventilation volume and airflow direction. The ventilation effect varies significantly under different seasons and weather conditions, making it impossible to consistently guarantee the suitable temperature and humidity environment required for shaking the plants. Utility Model Content
[0005] In order to overcome the above-mentioned shortcomings, the purpose of this utility model is to provide a shaking device for white tea processing.
[0006] The technical solution is as follows: A shaking device for white tea processing includes a base, a sieve cylinder, a track, pulleys, concave arms, a fan, an air outlet pipe, guide vanes, a feed plate, a support frame, and a rotating assembly. The support frame is connected to the top of the base. Concave arms are symmetrically connected to both sides of the support frame. Pulleys are rotatably connected to the upper and lower ends of the concave arms. The sieve cylinder is placed on the support frame, and tracks are sleeved on its left and right sides. The tracks slide and engage with the corresponding pulleys. The fan is connected to the left side of the support frame via an extension bracket. The air outlet of the fan is rotatably engaged with the left end of the sieve cylinder, and the two are interconnected. An air outlet pipe is connected to the right end of the fan. The air outlet pipe is located inside the sieve cylinder, and multiple air outlets are evenly spaced on its surface. Multiple guide vanes are evenly spaced on the inner wall of the sieve cylinder. The feed plate is rotatably connected to the right end of the sieve cylinder via two parallel hinges. A rotating assembly is provided on the support frame.
[0007] To further clarify, the feed plate has a transparent structure.
[0008] To further explain, the surface of the sieve cylinder has multiple holes evenly spaced apart.
[0009] To further explain, the rotating assembly includes a gear ring, a gear, and a motor. The motor is mounted on the upper left side of the support frame, and a gear is connected to the motor output shaft. A gear ring that meshes with the gear is connected to the outer left side of the screen cylinder.
[0010] To further explain, it also includes a dust cover, which is connected to the bottom of the support frame. The dust cover is located below the screen cylinder and covers the entire lower half of the screen cylinder.
[0011] To further explain, it also includes a waste bin and a handle. The waste bin for collecting waste is slidably connected to the lower side inside the dust cover, and a handle is connected to the left end of the waste bin.
[0012] The beneficial effects are: 1. The fan and the air outlet pipe work together to ventilate the inside of the sieve cylinder, which can effectively regulate the temperature and humidity inside the sieve cylinder, and prevent the tea leaves from being affected by excessive temperature or humidity, thus providing a suitable environment for the tea leaves to be shaken.
[0013] 2. The holes on the surface of the sieve cylinder can discharge tea leaves debris generated during the shaking process. Together with the dust cover and waste box below, waste can be collected in a unified manner, making it easy to clean and keeping the inside of the device clean, which is conducive to continuous and efficient shaking operation.
[0014] 3. When the guide plate inside the sieve cylinder rotates, it causes the tea leaves to rub against each other, damaging the edges of the leaves and stimulating enzymatic oxidation, which meets the key requirements of the shaking process and improves the shaking effect.

Detailed Implementation
[0020] The above-described solution will be further illustrated below with reference to specific embodiments. It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of this application. The implementation conditions used in the embodiments may be further adjusted according to the conditions of specific manufacturers, and the implementation conditions not specified are generally those in routine experiments.
[0021] Example: A shaking device for processing white tea, such as... Figures 1-4 As shown, the device includes a base 1, a screen cylinder 2, rails 4, pulleys 5, concave arms 6, a fan 9, an air outlet 10, a guide plate 11, a feed plate 14, a support frame 15, and a rotating assembly. The support frame 15 is connected to the top of the base 1. Concave arms 6 are symmetrically connected to both sides of the support frame 15, and pulleys 5 are rotatably connected to the upper and lower ends of the concave arms 6. The screen cylinder 2 is placed on the support frame 15, and rails 4 are fitted onto its left and right sides. The rails 4 and corresponding pulleys 5 slide and engage. The limiting effect of the concave arms 6 and pulleys 5 ensures the stability of the screen cylinder 2 when rotating on the support frame 15, effectively reducing swaying and deviation, and ensuring a smooth shaking process. A fan 9 is connected to the left side of the support frame 15 via an extension bracket. The air outlet of the fan 9 is rotatably engaged with the left end of the screen cylinder 2, and the two are interconnected. An air outlet pipe 10 is connected to the right end and is located inside the sieve cylinder 2. Multiple air outlets are evenly spaced on its surface. Multiple holes are evenly spaced on the surface of the sieve cylinder 2 for ventilation and to facilitate the discharge of tea debris generated during the shaking process. Multiple guide plates 11 are evenly spaced on the inner wall of the sieve cylinder 2. The guide plates 11 guide the tea leaves during the rotation of the sieve cylinder 2, promote friction between the tea leaves, and create favorable conditions for the enzymatic oxidation reaction during the shaking process. The right end of the sieve cylinder 2 is rotatably connected to a feed plate 14 through two parallel hinges. Tea leaves can be added into the sieve cylinder 2 simply by opening the feed plate 14. The feed plate 14 is transparent, making it easy to see the shaking process of the tea leaves inside the sieve cylinder 2 through the transparent plate. A rotating component is provided on the support frame 15.
[0022] like Figures 2-3 As shown, the rotating assembly includes a gear ring 7, a gear 8, and a motor 16. The motor 16 is bolted to the upper left side of the support frame 15. The gear 8 is connected to the output shaft of the motor 16. The gear ring 7, which meshes with the gear 8, is welded to the outer left side of the screen cylinder 2.
[0023] like Figures 3-4As shown, it also includes a dust cover 3, a waste box 12, and a handle 13. The dust cover 3 is connected to the bottom of the support frame 15. The dust cover 3 is located below the screen cylinder 2 and covers the entire lower half of the screen cylinder 2. The waste box 12 for collecting waste is slidably connected to the lower side of the dust cover 3. A handle 13 is welded to the left end of the waste box 12. Tea fragments generated during the shaking process fall into the dust cover 3 through the holes of the screen cylinder 2 and eventually fall into the waste box 12. The waste box 12 can be easily removed for cleaning by pulling the handle 13, keeping the inside of the device clean and reducing the impact of fragments on subsequent shaking operations.
[0024] During the shaking process of white tea processing, firstly, the feed plate 14 is opened by rotating the parallel hinge, and the tea leaves to be shaken are added into the sieve cylinder 2. After the leaves are added, the feed plate 14 is closed, and then the motor 16 is started. The output shaft of the motor 16 starts to rotate, driving the gear 8 connected to it to rotate synchronously, which in turn drives the gear ring 7 and the sieve cylinder 2 to rotate. The guide vane 11 inside the sieve cylinder 2 rotates together with the sieve cylinder 2. During the rotation, the guide vane 11 continuously changes the position and direction of movement of the tea leaves, causing friction between the tea leaves and damaging the leaf edges, thereby stimulating the enzymatic oxidation reaction. At the same time, when the sieve cylinder 2 rotates, the tracks 4 on both sides slide and engage with the pulleys 5. This engagement method greatly improves the stability of the sieve cylinder 2 during rotation, reduces the shaking and deviation of the sieve cylinder 2, and ensures the smooth progress of the shaking process. While the sieve cylinder 2 is rotating for shaking, the blower 9 is started. The blower 9 draws outside air into the air outlet 10. The air is discharged into the sieve cylinder 2 through multiple air outlets on the surface of the air outlet 10 and comes into full contact with the tea leaves. In this way, ventilation can be achieved inside the sieve cylinder 2, effectively regulating the temperature and humidity within it. This prevents the tea leaves from being affected by excessively high temperatures or humidity, which could negatively impact the shaking quality. During the shaking process, friction between the tea leaves and the rotation of the sieve cylinder 2 generate some tea leaf debris. This debris falls downwards through evenly spaced holes on the surface of the sieve cylinder 2, landing in the dust cover 3 located below it. The dust cover 3 collects the debris, ultimately placing it into the waste box 12, which is slidably connected to its lower side, facilitating later cleaning. After the shaking process is complete, the blower 9 and motor 16 are first turned off, stopping the rotation of the sieve cylinder 2 and the ventilation operation. Then, the feed plate 14 is opened to collect the shaken tea leaves. After collecting the tea leaves, the handle 13 connected to the left end of the waste box 12 is pulled to remove it from the dust cover 3, and the collected tea leaf debris is cleaned out, preparing for the next shaking operation.
[0025] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
