Description

Technical Field

[0001] This invention relates to the field of tea processing technology, and in particular to a tea fermentation production equipment. Background Technology

[0002] Tea leaves, commonly known as tea, generally include the leaves and buds of the tea plant. Fermented tea refers to all teas that undergo a fermentation process during production. Its initial processing includes withering, rolling, fermentation, and drying, followed by refining. Based on the degree of fermentation, teas can be categorized into lightly fermented teas, semi-fermented teas (such as Tieguanyin), fully fermented teas (such as black tea), and post-fermented teas (such as dark tea). The caffeine and vitamins in fermented teas can accelerate fat oxidation, thus aiding in weight loss. The polyphenols in tea, after fermentation and oxidation, reduce stomach irritation. Fully fermented black tea, under the action of oxidases, forms digestive aids, making it suitable for people with stomach discomfort.

[0003] Existing tea fermentation equipment has several shortcomings: First, insufficient oxygen supply and low oxygen content in the fermentation chamber lead to low fermentation efficiency and affect the overall tea yield. Second, tea leaves usually need to be manually spread out after being placed on the tray, which is time-consuming and labor-intensive. Third, the lack of an effective stirring mechanism during fermentation makes it difficult for oxygen to penetrate into the tea leaves, especially for deeper layers, resulting in uneven fermentation between the upper and lower layers and prolonging the overall fermentation time. Fourth, the presence of tea residue in the existing fermentation equipment creates a significant burden on subsequent screening processes due to the lack of effective separation methods.

[0004] Therefore, it is necessary to propose a tea fermentation production device to solve the above problems. Summary of the Invention

They are slidably connected to the fermentation tank and are limited by the limiting component through a snap ring. One of the drive shafts is driven to rotate and slide up and down by the second drive unit and is connected to the rotating ring through a transmission pair.

[0007] As a preferred embodiment of the present invention, the tray includes a tray body with a hollow cylinder fixed at its center.

[0008] As a preferred technical solution of the present invention, the stirring component includes a connecting ring, which is sleeved outside the hollow cylinder, and a connecting rod extending radially outward is fixed on its outer wall; The stirring rod is fixedly connected to the connecting rod, with its free end facing the inner bottom wall of the tray; The guide section, which is fixed to the end of the connecting rod away from the connecting ring, has a U-shaped structure, and the central groove of the U-shaped structure is inserted into the side wall of the tray.

[0009] As a preferred embodiment of the present invention, the portion of the guide located on the outside of the tray is connected to the side wall of the rotating ring via a pin to connect the stirring component and the rotating ring.

[0010] As a preferred technical solution of the present invention, it further includes a first elastic member, which is sleeved on the outside of the hollow cylinder and disposed between the connecting ring and the inner bottom wall of the tray.

[0011] As a preferred technical solution of the present invention, the rotating ring includes an annular member, the outer ring of which extends upward to form an annular baffle, and a bearing is provided between the ring and the tray and inside the annular baffle. The stepped part is fixed to the outer wall of the ring part, and the limiting ring is pressed onto the stepped part. The inner wall of the limiting ring is provided with a stepped groove that matches the stepped part.

[0012] As a preferred embodiment of the present invention, the transmission pair includes a gear ring, which is fixed to the outer wall of the annular baffle. The drive gear is fixed outside the transmission shaft and corresponds one-to-one with the gear ring, and it meshes with the gear ring.

[0013] As a preferred technical solution of the present invention, the second hollow rotating shaft includes an outer cylinder, which is connected to the output end of the first driving part in a transmission manner; The inner cylinder is fitted inside the outer cylinder and is slidably connected to the outer cylinder, and a limit ring is fixed on its outer wall; The second elastic element is sleeved outside the inner cylinder and located between the limiting ring and the inner wall of the fermentation chamber.

[0014] As a preferred technical solution of the present invention, the first driving part includes a driven gear, which is fixed on the outer cylinder and meshed with a driving gear. The first driving component has its output end connected to the drive gear transmission.

[0015] As a preferred technical solution of the present invention, the second driving part includes a hydraulic telescopic rod, which is fixed to the upper end of one of the transmission shafts; The second driving component has its output end fixedly connected to the hydraulic telescopic rod.

[0016] The technical effects and advantages of this invention are as follows: 1. The present invention, through the cooperative arrangement of components such as the first driving unit, the first hollow rotating shaft, the second hollow rotating shaft, and the supporting component, and through the control of the first driving unit and the second driving unit, can realize the relative rotation of the tray and the stirring component. After the tea leaves to be fermented are placed on the tray, the relative rotation of the tray and the stirring component can quickly and automatically spread the tea leaves.

[0017] 2. Through the coordinated arrangement of components such as the first hollow rotating shaft, the second hollow rotating shaft, the air supply system, and the support assembly, the present invention can continuously introduce pure oxygen or oxygen-enriched gas into the fermentation chamber during the tea fermentation process, thereby increasing the oxygen content in the fermentation chamber, improving fermentation efficiency, and thus increasing the overall yield of tea.

[0018] 3. The present invention, through the cooperative arrangement of components such as the first driving unit, the first hollow rotating shaft, the second hollow rotating shaft, and the supporting assembly, and controlled by the first and second driving units, enables the relative rotation of the tray and the stirring component. This allows for stirring of the tea during the tea fermentation process, promoting oxygen penetration into the tea leaves. At the same time, the fan blades located inside the rotating ring further enhance oxygen penetration, allowing even the deeper layers of tea leaves to fully contact oxygen, thereby further improving the uniformity and efficiency of fermentation.

[0019] 4. By combining the filter components and the tray with a mesh bottom with the stirring of tea leaves, this invention can effectively separate and collect the tea leaves into the filter components, thereby reducing the amount of tea leaves in the tea leaves after the fermentation process and reducing the workload of the subsequent slag removal process.

[0020] 5. By setting up a slag scraper, the present invention can automatically scrape the upper surface of the filter component, preventing debris from clogging the mesh and maintaining the air permeability and flow area. It also avoids debris from entering the gaps between the parts, causing wear, jamming, or even damage to the parts, thereby reducing the frequency of equipment maintenance and extending the maintenance-free operation cycle.

Detailed Implementation

[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] This invention provides, for example Figures 1 to 9 The tea fermentation production equipment shown includes a fermentation box 1, which is equipped with a heating component 2 and a humidification component 3 inside, a dehumidification component 4 on the top, a temperature sensor and a humidity sensor inside, casters installed at the bottom, a door hinged to one side, and a control panel installed on the top for controlling the opening and closing of the equipment and setting parameters such as temperature and humidity during the fermentation process.

[0033] Specifically, the fermentation chamber 1 adopts a hollow double-layer structure; the heating component 2 is an electric heating tube installed in the hollow cavity of the fermentation chamber 1 to increase the temperature inside the fermentation chamber 1 to meet the temperature conditions required during tea fermentation; the humidification component 3 is an atomizing plate that can spray atomized water vapor into the fermentation chamber 1 after connecting to an external water source to increase the humidity inside the fermentation chamber 1 to meet the humidity conditions required during tea fermentation. There are multiple atomizing plates, with two atomizing plates corresponding to each tray 84, which are located on both sides of the tray 84 to improve the response speed of humidity adjustment and raise the humidity inside the fermentation chamber 1 to the set value in a short time; the dehumidification component 4 is located on the upper side of the fermentation chamber 1, which includes a dehumidification fan and a cover covering the dehumidification fan. The top of the cover has ventilation holes. When the humidity inside the fermentation chamber 1 is too high, the humidification component 3 is turned off and the dehumidification fan is turned on to reduce the humidity inside the fermentation chamber 1 to the set humidity.

[0034] Specifically, a first hollow rotating shaft 5 is rotatably provided on the inner wall of the bottom of the fermentation tank 1, and a second hollow rotating shaft 6, driven by a first driving unit 7, is rotatably and slidably provided on its top. Specifically, the second hollow rotating shaft 6 includes an outer cylinder 61, which is connected to the output end of the first driving unit 7; an inner cylinder 62, which is sleeved inside the outer cylinder 61 and slidably connected to the outer cylinder 61, and a limiting ring 64 is fixed on its outer wall; and a second elastic member 63, which is sleeved outside the inner cylinder 62 and located between the limiting ring 64 and the inner wall of the fermentation tank 1.

[0035] Specifically, the first drive unit 7 includes a driven gear 71, which is fixed to the outer cylinder 61 and meshes with a drive gear 72; and a first drive member 73, whose output end is connected to the drive gear 72. The first drive member 73 is a first drive motor, whose output shaft is connected to the drive gear 72 via a keyway. A first cover is mounted on the upper side of the fermentation tank 1 by screws, and the first drive motor is mounted on the upper side of the first cover by screws.

[0036] Specifically, the outer cylinder 61 of the second hollow shaft 6 is connected to an external gas supply system to supply pure oxygen or oxygen-enriched gas into the fermentation chamber 1. During connection, the outer cylinder 61 needs to be connected to the gas pipe of the external gas supply system through a rotary joint to meet the gas supply requirements of the second hollow shaft 6 under rotation conditions.

[0037] Specifically, a plurality of linearly distributed and interlocked support components 8 are provided between the first hollow shaft 5 and the second hollow shaft 6. The support component 8 includes a hollow shaft 81, a turbine blade 82 is rotatably provided on its circumferential sidewall, and a plurality of circumferentially uniformly distributed air passage holes 83 are opened on its sidewall, and the air passage holes 83 are inclined toward the direction of the turbine blade 82.

[0038] Specifically, the hollow shaft 81 is provided with a plug-in structure, which includes slots and inserts located at both ends of the hollow shaft 81. The slots are rectangular grooves opened axially into the inner wall of the hollow shaft 81, and the inserts are rectangular blocks fixed to the reduced-diameter section of the outer wall of the hollow shaft 81. A sealing gasket is provided at the plug-in joint of the hollow shaft 81 to prevent gas inside the shaft from leaking out from the gap at the plug-in joint.

[0039] Specifically, the tray 84 includes a tray body 841, with a hollow cylinder 842 fixed at its center. The bottom of the cylinder 842 has a mesh structure, which is detachably fitted onto the hollow shaft 81 by screws. The mesh structure at the bottom allows tea leaves to fall through the mesh holes onto the filter component 88 below during the stirring process, reducing the amount of tea leaves after the fermentation process and alleviating the workload of the subsequent slag removal process.

[0040] Specifically, the bottom of the tray 84 is equipped with a scraper 85, which can automatically scrape the upper surface of the filter component 88 to prevent debris from clogging the mesh of the filter component 88, maintain the air permeability and flow area, and prevent debris from entering the gaps between the parts, causing wear, jamming, or even damage to the parts. This reduces the frequency of equipment maintenance and extends the maintenance-free operation cycle. Specifically, the scraper 85 is a rectangular plate located at the bottom of the tray 84. During installation, a metal plate with through holes can be fixed to the mesh structure at the bottom of the tray 84, and threaded holes are machined into the rectangular plate. A double-ended stud is used, with one end screwed into the threaded hole of the rectangular plate and the other end passing through the through hole of the metal plate and locked in place by a nut.

[0041] Specifically, the stirring component 86 is movably disposed inside the tray 84, and can rotate and slide up and down relative to the tray 84. The stirring component 86 includes a connecting ring 861, which is sleeved outside the hollow cylinder 842, and a connecting rod 862 extending radially outward is fixed to its outer wall; a plurality of stirring rods 863, which are evenly distributed along the length of the connecting rod 862 and are fixedly connected to the connecting rod 862, with their free ends facing the inner bottom wall of the tray 84; and a guide part 864, which is fixed to the end of the connecting rod 862 away from the connecting ring 861, has a U-shaped structure, and the central groove of the U-shaped structure is inserted into the side wall of the tray 84.

[0042] Specifically, the first elastic element 817 is sleeved outside the hollow cylinder 842 and disposed between the connecting ring 861 and the inner bottom wall of the tray 84. The first elastic element 817 is used to assist in supporting the stirring component 86. When the stirring component 86 moves upward, it can also assist in pushing the middle part of the stirring component 86 upward, improving the smoothness of the upward movement of the stirring component 86.

[0043] Specifically, the rotating ring 87 is located at the bottom of the tray 84, and its inner wall is detachably connected from top to bottom to a filter element 88 and a fan blade 89, which are detachably connected to the stirring element 86. Specifically, both the filter element 88 and the fan blade 89 are threadedly connected to the rotating ring 87. The filter element 88 includes a screen and an annular support frame fixed to the inner and outer rings of the screen. The screen aperture size is designed to prevent tea leaves from passing through, thereby intercepting the tea leaves on the upper side of the filter element 88.

[0044] Specifically, the rotating ring 87 includes an annular part 871, the outer ring of which extends upward to form an annular baffle 872. A bearing 873 is provided between the ring and the tray 84 and inside the annular baffle 872. The bearing 873 is a thrust bearing to reduce the frictional resistance when the rotating ring 87 rotates relative to the tray 84. A stepped part 874 is fixed to the outer wall of the annular part 871.

[0045] Specifically, the portion of the guide section 864 located on the outer side of the tray 84 is connected to the side wall of the rotating ring 87 via a pin 816, thereby connecting the stirring component 86 and the rotating ring 87. Specifically, the portion of the guide section 864 located on the outer side of the tray 84 has a blind hole, and the side wall of the rotating ring 87 has a through hole corresponding to the blind hole; the pin 816 is inserted into the blind hole and the through hole.

[0046] Specifically, the limiting member 810 is located at the bottom of the rotating ring 87, and its top is detachably connected by screws to a limiting ring 811 that is pressed against the rotating ring 87 and rotatably connected to the rotating ring 87. Specifically, the limiting ring 811 is pressed against the stepped portion 874 of the rotating ring 87, and the inner wall of the limiting ring 811 is provided with a stepped groove that matches the stepped portion 874.

[0047] Specifically, two symmetrically arranged drive shafts 812 rotatably pass through the fermentation tank 1 and the limiting member 810, and are slidably connected to the fermentation tank 1. They are limited by a snap ring 813 to the limiting member 810. The drive shafts 812 and the rotating ring 87 are connected by a transmission pair 815. The transmission pair 815 includes a gear ring 8151, which is fixed to the outer wall of the annular baffle 872; and a drive gear 8152, which is fixed to the outside of the drive shafts 812 and corresponds one-to-one with the gear ring 8151, and is meshed with the gear ring 8151.

[0048] Specifically, one drive shaft 812 is driven to rotate and slide up and down by the second drive unit 814, while the other drive shaft 812 can move synchronously with it through the transmission pair 815, the limiting member 810, and the retaining ring 813. The drive shaft 812 is provided with an annular groove, and the retaining ring 813 is engaged in the annular groove. The retaining ring 813 allows the limiting member 810 to move up and down synchronously with the drive shaft 812.

[0049] Specifically, the ends of the two drive shafts 812 that are not connected to the second drive unit 814 are provided with spline shafts, and spline sleeves are slidably fitted on the outside of the spline shafts. One end of the spline sleeves is rotatably connected to the fermentation tank 1.

[0050] Specifically, the second drive unit 814 includes a hydraulic telescopic rod 8141, which is fixed to the upper end of one of the transmission shafts 812; and a second drive component 8142, the output end of which is fixedly connected to the hydraulic telescopic rod 8141. The second drive component 8142 is a second drive motor. A second cover is mounted on the upper side of the fermentation tank 1 by screws, and the second drive motor is mounted on the upper side of the second cover by screws.

[0051] In use, firstly, the tea leaves to be fermented are poured into the tray 84. Then, the first drive unit 73 is activated, and its output shaft drives the drive gear 72 to rotate. The drive gear 72 meshes with the driven gear 71, and the driven gear 71 drives the outer cylinder 61 of the second hollow rotating shaft 6 to rotate. The outer cylinder 61 drives the inner cylinder 62 to rotate through the spline structure. The inner cylinder 62 drives the hollow shaft 81 and the first hollow rotating shaft 5 to rotate synchronously through the plug-in structure, thereby causing the tray 84 and the tea leaves inside to begin to rotate horizontally.

[0052] Simultaneously, the second drive unit 8142 is activated, and its output shaft drives the hydraulic telescopic rod 8141 to move. The hydraulic telescopic rod 8141 drives the transmission shaft 812 to rotate and pushes the transmission shaft 812 downward. The rotation of the transmission shaft 812 is transmitted to the gear ring 8151 meshing with it through the drive gear 8152. The gear ring 8151 is fixed to the outer wall of the rotating ring 87, thereby driving the rotating ring 87 to rotate. The rotating ring 87 is connected to the stirring component 86 through the pin 816, so the stirring component 86 rotates around the hollow shaft 81 together with the rotating ring 87.

[0053] The hydraulic telescopic rod 8141 continuously pushes the drive shaft 812 downward. The drive shaft 812 is connected to the limiting member 810 via a snap ring 813. A limiting ring 811 is connected to the limiting member 810, and the limiting ring 811 presses against the stepped portion 874 of the rotating ring 87. As the drive shaft 812 moves downward, the limiting ring 811 pushes the rotating ring 87 to slide downward as a whole. The downward movement of the rotating ring 87 pulls the stirring component 86 down relative to the tray 84 via the pin 816, causing the stirring rod 863 to insert into the tea leaves. During this process, the first elastic element 817 between the stirring component 86 and the tray 84 is compressed and stores energy, providing elastic force for the subsequent upward repositioning of the stirring component 86. After the stirring rod 863 descends, it rotates to flatten the accumulated tea leaves, forming a fermentation layer of uniform thickness.

[0054] After being flattened, the fermentation process begins. Heating component 2, humidifying component 3, and dehumidifying component 4 work together to control the temperature and humidity inside fermentation chamber 1 at the set values.

[0055] The second hollow shaft 6 is connected to an external air supply system, which introduces pure oxygen or oxygen-enriched gas into the interior of the hollow shaft 81. An airflow hole 83 is provided on the side wall of the hollow shaft 81, through which the gas is sprayed onto the turbine blades 82. The turbine blades 82 rotate around the hollow shaft 81 under the thrust of the airflow, and the blades simultaneously guide the airflow. The blade angle causes the incoming airflow to be thrown outwards under centrifugal force, forming a diffused flow that covers the upper layer of the tea leaves. This utilizes both the thrust of the airflow for rotation and the centrifugal force generated by the rotation to disperse the airflow, improving the uniformity of contact between the tea leaves and oxygen.

[0056] A fan blade 89 is installed inside the rotating ring 87. When the rotating ring 87 rotates, the fan blade 89 rotates accordingly, creating a low-pressure zone below the tray 84. This low-pressure zone guides the gas above the tray 84 through the tea layer and downwards, ensuring that the bottom tea leaves also receive sufficient oxygen and improving the uniformity of fermentation.

[0057] The stirring component 86 rotates around the hollow shaft 81 with the rotating ring 87. Simultaneously, due to the periodic extension and retraction of the hydraulic telescopic rod 8141, it reciprocates up and down relative to the tray 84 via the transmission shaft 812, snap ring 813, limiting member 810, limiting ring 811, rotating ring 87, and pin 816. This combined motion of circumferential rotation and axial reciprocating movement continuously stirs the tea leaves, increasing the contact area between the tea leaves and oxygen, and improving fermentation efficiency. The first elastic member 817 releases stored energy when the stirring component 86 rises, assisting its upward reset.

[0058] During the stirring process, tea leaves debris falls through the mesh structure at the bottom of tray 84 onto the filter element 88 below. The sieve openings of filter element 88 are designed to prevent tea leaves debris from passing through, thus trapping the debris on its upper surface. This reduces the debris content in the tea leaves after the fermentation process and lightens the workload of subsequent slag removal processes.

[0059] A scraper 85, which rotates synchronously with the tray 84, is connected to the lower side of the tray. A filter element 88, which rotates synchronously with the rotating ring 87, is connected to the inner side of the rotating ring 87. When the rotating ring 87 is in its highest position (i.e., Figure 7 When the position shown is such that the scraper 85 is in contact with the upper surface of the filter element 88, the scraper 85 continuously scrapes the upper surface of the filter element 88 as the tray 84 and the rotating ring 87 rotate relative to each other. This prevents debris from clogging the mesh, maintains the air permeability and flow area, and avoids debris from entering the interior of the parts or the gaps between the parts, causing wear, jamming, or even damage to the parts. This reduces the frequency of equipment maintenance and extends the maintenance-free operation cycle.

[0060] After fermentation is complete, remove the pin 816 to disconnect the stirring component 86 from the rotating ring 87. Hold the top edge of the tray 84 and pull it upwards, causing the tray 84 to lift together with the hollow shaft 81, stirring component 86, first elastic element 817, turbine blades 82, and scraper 85. The top of the hollow shaft 81 pushes the inner cylinder 62 of the second hollow rotating shaft 6 upwards, while compressing the second elastic element 63. Once the uppermost hollow shaft 81 separates from the next section of the hollow shaft 81, the tray 84 and its connected components can be removed, making it easy to pour out the fermented tea leaves.

[0061] Subsequently, depending on the amount of tea leaves accumulated on the filter element 88, it can be selectively unscrewed from the rotating ring 87 to clean the accumulated tea leaves for the next use.

[0062] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. 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.
