Description

Technical Field

[0001] This utility model relates to the technical field of tea production equipment, specifically an automatic adjustment system for the withering and shaking cycle. Background Technology

[0002] Dancong tea is a special type of oolong tea, belonging to the semi-fermented category, possessing its own unique style and excellent quality. The initial processing of Dancong tea consists of six steps: sun-drying, air-drying, oxidation, fixation, rolling, and roasting. Among these, oxidation is the key process for forming its quality characteristics, consisting of multiple alternating processes of shaking and resting. Through oxidation, the grassy aroma in the fresh leaves transforms into aromatic substances and the unique floral and fruity flavors of Dancong tea.

[0003] "Air-drying" refers to the process of spreading freshly picked single-clump leaves out in a specific environment (low light / no light, well-ventilated) to allow some moisture to evaporate naturally, while simultaneously triggering preliminary physical and chemical changes. It is the preliminary stage of "withering" (the withering of single-clump leaves usually includes "air-drying" and "sun-drying," but air-drying focuses more on "moisture loss under low light / indoor conditions," which distinguishes it from sun-drying under strong light); air-drying must be carried out in low light / indoors (strong light will cause the leaf temperature to rise sharply, destroying enzyme activity and chlorophyll).

[0004] Withering is the "preliminary foundation" for shaking, and its degree directly determines the shaking effect: If the withering is insufficient (too much moisture): the leaves are easily damaged by friction during shaking, resulting in "water-stained" rot, uneven fermentation, and a dull aroma, bitter taste, and yellowish liquor (caused by a dull yellow color). If the withering is excessive (too little moisture): the leaves lack resilience and are easily broken during shaking, making fermentation difficult, resulting in a weak aroma, bland taste, and light liquor. For Dancong tea, the "degree" of withering needs to be flexibly adjusted based on the characteristics of the variety (such as aroma type), the condition of the fresh leaves (age, moisture content), and environmental conditions. The ultimate goal is to make the fresh leaves "soft but not rotten, fragrant but not bland," laying the foundation for the subsequent "fermentation transformation" and "aroma refinement" during shaking.

[0005] Currently, the withering process is usually done manually. After sun-drying, the fresh tea leaves are collected and spread evenly in a cool, shady place to dry. Temperature, humidity, and ventilation are determined by the environment and require manual control of the withering time. Because it is done manually, the experience and quality of the workers determine the effectiveness of the withering and shaking processes, making it impossible to establish relatively standardized and planned production indicators. Furthermore, the withering and shaking processes require considerable labor intensity, and manual operation limits the possibility of large-scale production. Utility Model Content

[0006] The purpose of this utility model is to provide an automatic adjustment system for the withering and shaking cycle, so as to solve the technical problems of unstable tea quality and low production efficiency caused by manual withering and shaking operations in the above-mentioned background art.

[0008] An automatic adjustment system for the withering and shaking cycle includes a conveying withering device and a shaking machine. The conveying withering device is equipped with several circulating chain conveyor belts via a withering mounting frame. Along the circulating direction of the chain conveyor belts, the sun-dried tea leaves enter the starting end of the conveying withering device, where they spread out and circulate with the chain conveyor belts for withering.

Support plates are arranged parallel to each other on the chain guide plate corresponding to the support rollers.

[0015] Furthermore, the first chain plate flipping mechanism includes flipping station notches formed on both side support plates. When the chain plate reaches the flipping station notch, the chain plate flips along the hinge post, causing the tea leaves to fall onto the next layer of the chain plate conveyor belt.

[0016] Furthermore, the chain conveying device includes a chain conveying support and a chain conveyor belt module disposed on the chain conveying support. One end of the chain conveying module is provided with a chain conveying drive component, and the starting end of the chain conveyor belt module is disposed below the first chain plate flipping mechanism of the lowest chain plate conveyor belt.

[0038] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0039] Example 1

[0040] like Figure 1As shown in the figure, this utility model embodiment proposes an automatic adjustment system for the withering and shaking cycle, including a conveying withering device 10 and a shaking machine 40. The conveying withering device 10 is equipped with several circulating chain conveyor belts 12 via a withering mounting frame 11. Along the circulating direction of the chain conveyor belts 12, the withered tea leaves enter the starting end of the conveying withering device 10, where they spread out and are withered as the chain conveyor belts 12 circulate. At the end of the conveying withering device 10, the tea leaves enter the shaking drum 45 of the shaking machine 40 for shaking, and the shaken tea leaves are then conveyed back to the starting end of the conveying withering device 10. The running speed of the chain conveyor belts 12 and the tilt angle of the shaking drum 42 of the conveying withering device 10 are controlled to control the withering time and the shaking time.

[0041] We know that the "degree" of withering and shaking needs to be flexibly adjusted based on the characteristics of the variety (such as aroma type), the state of the fresh leaves (age and moisture content), and environmental conditions. Since the system equipment is placed indoors, it can automatically control environmental conditions such as temperature, humidity, ventilation, and lighting. Different types of tea processing require different withering and shaking times or cycles. Through the aforementioned system, automated operation can be achieved by pre-setting the chain conveyor belt speed, the tilt angle of the shaking drum, and environmental adjustment parameters. Furthermore, machine learning, such as image recognition, can be used to perceive the withering and shaking status of the tea leaves in real time, thereby intelligently adjusting the withering time, shaking time, and number of cycles. This achieves automated, standardized, intelligent, and large-scale operation of the withering and shaking process. Specifically, the automatic adjustment system for the withering and shaking cycle also includes a chain conveyor 20 and a first lifting conveyor 30. The withered tea leaves are conveyed from the end of the conveying and withering device 10 to the beginning of the first lifting conveyor 30 via the chain conveyor 20. The first lifting conveyor 30 lifts and conveys the tea leaves into the shaking drum 45 of the shaking machine 40 for shaking.

[0042] Specifically, the automatic adjustment system for the withering and shaking cycle also includes a circulation conveying device 50 and a second lifting conveying device 60. After shaking, the tea leaves fall from the end of the shaking drum 45 into the circulation conveying device 50. The circulation conveying device 50 transports the tea leaves to the starting end of the second lifting conveying device 60. The second lifting conveying device 60 lifts and conveys the tea leaves into the starting end of the conveying and withering device 10 to start withering again.

[0043] like Figure 2 , 3As shown, the conveying and drying device 10 includes multiple layers of chain conveyor belts 12 arranged sequentially on the drying mounting frame 11. Each chain conveyor belt 12 has a sprocket 13 at both ends, and a drying transmission assembly 14 is provided corresponding to each sprocket 13 of the chain conveyor belt 12. The drying transmission assembly 14 is connected to a drying drive assembly 15 to drive all the chain conveyor belts 12 to run synchronously. Along the cyclic running direction of the chain conveyor belts 12, a first chain plate flipping mechanism 16 is provided at the end of each layer of chain conveyor belts 12. When the tea leaves are conveyed to the position of the first chain plate flipping mechanism 16, they fall to the starting end of the chain conveyor belt 12 of the next layer.

[0044] The starting end of the conveyor drying device 10 is equipped with a feeding guide 17, which is positioned above the chain conveyor belt 12. After drying, the tea leaves fall from the feeding guide 17 onto the chain conveyor belt 12. Because there is a certain height difference between the feeding guide 17 and the chain conveyor belt 12, the chain conveyor belt 12 circulates as the tea leaves fall, distributing the tea leaves evenly on the chain conveyor belt 12. By controlling the height difference, the amount of tea leaves falling, and the running speed of the chain conveyor belt 12, it is ensured that the tea leaves are evenly distributed on the chain conveyor belt 12. Specifically, the dried leaves are automatically dropped from the feeding guide 17 into the designed and manufactured 32-meter eight-layer chain conveyor belt for drying. This device is equivalent to the capacity of 80 shaking machines currently widely used in production areas. The effective usable area is approximately 120 square meters. 2 It replaced 80 shaking machines, occupying an area of ​​nearly 1000 square meters. 2 .

[0045] Optionally, along the cyclic running direction of the chain conveyor belt 12, baffles 19 are provided on both sides of each layer of the chain conveyor belt 12. The baffles 19 are used to disperse and adjust the distribution thickness of tea leaves on the chain conveyor belt 12.

[0046] Optionally, a camera module 18 is also provided above the chain conveyor belt 12, the camera module 18 being used to capture images of tea leaves on the chain conveyor belt 12.

[0047] like Figure 4 , 5 As shown, the chain conveyor belt 12 includes drive chains 122 on both sides and multiple chain plates 121 that are rotatably arranged between the two drive chains 122. The drive chains 122 are respectively arranged on the drying rack 11 through a chain guide plate 123.

[0048] Specifically, along the cyclic running direction of the chain conveyor belt 12, each chain plate 121 is mounted on the drive chain via a hinge post 1212 on both sides of its front end. Each chain plate 121 has support rollers 1211 on both sides of its rear end, and support plates 124 are arranged parallel to each other on the chain guide plate 123 corresponding to the support rollers 1211. The first chain plate flipping mechanism 16 includes flipping station notches 161 formed on the support plates 124 on both sides. When the chain plate 121 reaches the flipping station notch 161, the chain plate 121 flips along the hinge post 1212, causing the tea leaves to fall onto the next layer of the chain conveyor belt 12.

[0049] like Figure 6 As shown, along the cyclic running direction of the chain conveyor belt 12, guide wheel sets 162 and limit blocks 163 are respectively provided in the flipping station gap 161 corresponding to each chain plate 121 before and after.

[0050] like Figure 7 , 8 As shown, the chain conveyor device 20 includes a chain conveyor support 1 and a chain conveyor belt module 22 disposed on the chain conveyor support 21. One end of the chain conveyor module 22 is provided with a chain conveyor drive component 23, and the starting end of the chain conveyor belt module 22 is disposed below the first chain plate flipping mechanism 16 of the lowest chain plate conveyor belt 12.

[0051] As shown in 7 and 8, the first lifting and conveying device 30 includes a lifting and conveying support 31, a lifting and conveying belt module 32 disposed on the lifting and conveying support 31, a lifting and conveying drive assembly 33 disposed at one end of the lifting and conveying belt module 32, the starting end of the lifting and conveying belt module 32 is disposed below the second chain plate flipping mechanism 24 of the chain conveyor belt module 22, and the ending end of the lifting and conveying belt module 32 is disposed at the feeding end of the shaking drum 45 of the shaking machine 40.

[0052] Optionally, the first chain plate flipping mechanism 16 and the second chain plate flipping mechanism 24 have the same structural principle.

[0053] like Figure 9 As shown, the shaking machine 40 includes a main frame 41 and a shaking roller 45 disposed within the main frame 41. The shaking roller 45 is disposed on a roller mounting support 410, which is disposed on an inclined seat plate 411. One end of the inclined seat plate 411 is provided with an inclined hinge seat 412 on the upper side of the main frame 41, and the other end of the inclined seat plate 411 is provided with a lifting screw mechanism 413. The lifting screw mechanism 413 is connected and driven by a lifting drive motor 414.

[0054] Specifically, the shaking process is the most crucial step in oolong tea production. Currently, the shaking machines used in the industry are individual machines operated separately, lacking standardization and involving high labor intensity. Each shaking cycle (usually every 1.5-2 hours, requiring a total of 5-7 cycles) requires manual labor to spread the tea leaves evenly in the shaking basket. This system, however, features an outlet at the end of the drying line, connected to an automatic conveyor belt, and an automatic shaking machine. This machine is adjustable in speed and output, achieving the traditional requirements of shaking from light to heavy and from few to many rotations each time.

[0055] Specifically, the shaking roller 45 is provided with a plurality of roller drive rings 46, and a roller drive wheel 47 is provided corresponding to the roller drive rings 46. The roller drive wheel 47 is mounted on a rolling drive shaft 48, and one end of the roller drive shaft 48 is connected to and driven by a roller motor 49.

[0056] Optionally, an upper frame 42 is also provided on the upper side of the main frame 41 of the equipment. The upper frame 42 is provided with a feed hopper 43 and a discharge hopper 44 corresponding to the feed end and discharge end of the shaking drum 45, respectively.

[0057] By setting an inclined seat plate 411 on the shaking machine 40, the tilt angle is controlled so that the shaking drum 45 tilts, thereby further controlling the residence time of the tea leaves in the shaking drum 45. In conjunction with controlling the rotation speed and tilt angle of the shaking drum 45, the shaking time of the tea leaves can be precisely controlled.

[0058] like Figure 7 , 8 As shown, the circulating conveying device 50 includes a circulating conveying frame 51, a circulating conveyor belt module 52 disposed on the circulating conveying frame 51, and a circulating conveying drive assembly 53 disposed at one end of the circulating conveyor belt module 52. The starting end of the circulating conveyor belt module 52 is disposed below the discharge end of the shaking drum 45 of the shaking machine 40. The tea leaves enter the starting end of the second lifting conveying device 60 at the end of the circulating conveyor belt module 52, and then enter the starting end of the conveying and drying device 10 at the end of the second lifting conveying device 60 to start drying again.

[0059] Specifically, the first lifting and conveying device 30 and the second lifting and conveying device 60 have the same structural principle.

[0060] This utility model's automatic adjustment system for the withering and shaking cycle comprises a withering device, a shaking machine, and multiple conveying devices to form a withering and shaking cycle system. Based on the processing requirements of different tea varieties, it precisely controls the withering and shaking time and the number of cycles through real-time sensing or parameter settings, automating the entire withering and shaking process and adapting to different tea processing techniques. This system replaces the current method of relying entirely on manual operation with automation, forming a closed-loop continuous flow operation from withering to shaking to achieve automation and standardization. It effectively reduces labor intensity, avoids the instability of manual operation, and greatly improves the quality of tea.

[0061] Although the present invention 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. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
