Description

Technical Field

[0001] The invention relates to the technical field of semi-fermented tea production, in particular to a rolling device for producing lightly semi-fermented tea. Background Art

[0002] ‌Lightly semi-fermented tea‌ refers to tea whose fermentation degree is between 10% and 30% during the tea making process. During the making process of this type of tea, the chlorophyll in the tea leaves is partially destroyed and lightly fermented at the same time. Lightly semi-fermented tea has the fragrance of green tea and the mellowness of black tea. It has a relatively refreshing taste, with a certain fruity and floral aroma, and retains more natural aroma and refreshing taste. Semi-fermented tea has the characteristics of both unfermented tea (such as green tea) and fully fermented tea. The main nutrients are tea polyphenols and caffeine, so it is widely welcomed by people.

[0003] The rolling process in tea processing is a key step in shaping the shape of tea leaves, promoting the transformation of internal substances and forming a unique flavor. For lightly semi-fermented tea (such as some oolong teas, white teas, etc.), rolling can break the tea leaf tissue and cause the tea juice to overflow, providing favorable conditions for subsequent fermentation, enhancing the activity of enzymes in the tea leaves, and further catalyzing the changes in the internal substances of the tea leaves, thereby making the taste of the tea leaves richer and the aroma more intense. Rolling can transform the tea leaves from a flat or loose state to a tight, curved or strip-like state, which is not only convenient for storage and transportation, but also improves the quality and taste of the tea soup, etc., and the tea leaves after proper rolling are easier to dry evenly, avoiding the occurrence of local over-drying or under-drying, and ensuring the stability of the tea quality. The production of semi-fermented tea relies on rolling to balance the aroma, taste and appearance of the finished tea. However, the existing rolling equipment still has some defects or deficiencies in adapting to the refined processing needs of such tea leaves:

[0004] 1. Traditional rolling devices (such as disc rolling machines and roller rolling machines) mostly use fixed pressure modes or simple mechanical adjustments. It is difficult to dynamically adjust the rolling force according to the moisture content of tea leaves, leaf thickness and other characteristics. In the processing of semi-fermented tea, gentle rolling is required in the early stage to avoid premature rupture of the cell wall, and pressure needs to be gradually increased in the later stage to promote enzymatic oxidation. However, the existing rolling devices are very likely to cause pressure overload or insufficient, resulting in increased leaf breakage rate or uneven rolling, which seriously affects the integrity of the finished tea and the taste of the tea soup;

[0005] 2. The fermentation degree of light semi-fermented tea needs to be controlled within a certain range. However, during the rolling process, the friction of the tea leaves can easily cause a sudden rise in local temperature, thereby accelerating the non-enzymatic oxidation of polyphenols, resulting in excessive enzyme activity, causing over-fermentation, and causing the aroma substances in the tea leaves to evaporate quickly, causing the aroma to become weak, thus deviating from the target flavor of light semi-fermentation.

[0006] 3. Existing rolling devices mostly adopt a continuous unidirectional rolling mode, which causes the tea leaves to be subjected to a single mechanical shear force and cannot simulate the "flipping-deblocking-re-rolling" action of manual rolling. Therefore, the rolled tea leaves have low compactness and insufficient aroma release efficiency, which restricts the production quality of semi-fermented tea. Summary of the invention

[0048] like Figure 1-10 As shown, a rolling device for producing light semi-fermented tea comprises: a table 1, a processing round plate 2 fixedly mounted on the table 1, a controllable rolling device 3 mounted on the table 1, and a deblocking and re-closing mechanism 4 arranged on the controllable rolling device 3, the processing round plate 2 and the table 1, wherein:

[0049] The controllable rolling device 3 is driven to enter the processing circular dish 2 and hold the tea leaves in a ball shape and then rotate irregularly to drive the tea leaves to roll;

[0050] The controllable kneading device 3 is suitable for adjusting the tightness and downward pressure of the tea leaves so that the tea leaves are subjected to various forces;

[0051] The deblocking and re-closing mechanism 4 is driven to be inserted into the tea clump and to emit high-pressure air columns to disperse the tea leaves;

[0052] The deblocking and gathering mechanism 4 is suitable for driving the scattered tea leaves in the processing circular dish 2 to the center of the processing circular dish 2 to gather the scattered tea leaves. The tea leaves can be kneaded into a ball by the controllable kneading device 3, so that during the kneading process, the ball-shaped tea leaves are driven to roll, and the tea leaves can also be squeezed and rubbed against each other, thereby promoting the outflow of tea juice and improving the kneading effect. The controllable kneading device 3 can adjust the circumferential holding force and vertical pressure on the tea leaves respectively, so as to achieve fine control of the kneading force, thereby ensuring that a gentle force can be used in the early stage of kneading, and a higher pressure force can be used in the later stage, so as to achieve dynamic adjustment of the kneading force according to the moisture content of the tea leaves, the thickness of the leaves and other characteristics, effectively preventing the occurrence of pressure overload or insufficient pressure, and effectively reducing The tea leaves are easily crushed and evenly kneaded. The deblocking and re-gathering mechanism 4 can be inserted into the tea mass and high-pressure air columns can be blown from the inside out to scatter the tea mass. At the same time, the tea leaves can be gathered together again to restore the mass, and then the "flipping-deblocking-re-kneading" action of manual kneading can be simulated with the cooperation of the controllable kneading device 3, thereby enriching the kneading mode, increasing the mechanical shear force on the tea leaves, and then improving the tightness of the tea leaves, helping the efficient release of aroma substances. The kneading device for producing light semi-fermented tea has the advantages of high efficiency of mechanical processing, and at the same time imitates the key points of manual kneading as much as possible, effectively improving the integrity and taste of the tea soup under mechanical kneading, and effectively improving the production quality of semi-fermented tea.

[0053] Optionally, the controllable kneading device 3 includes a first motor 31 and a first pulley 32 installed side by side on the bottom surface of the table 1, and the output shaft of the first motor 31 is connected to the first pulley 32 through a coupling, two hanging plates 33 installed on the bottom surface of the table 1 and away from the first pulley 32 are installed at intervals, a rotating shaft 34 rotatably installed on the two hanging plates 33, and one end of the rotating shaft 34 protrudes from the hanging plate 33 on one side, a second pulley 35 installed on the rotating shaft 34 and located between the two hanging plates 33, and the first pulley 32 and the second pulley 35 are collinear, a plurality of belts 36 sleeved on the first pulley 32 and the second pulley 35, a driving gear 37 installed on the protruding part of the rotating shaft 34, a driven gear 38 rotatably installed on the two hanging plates 33, and the driving gear 37 and the driven gear 38 are meshed, and installed on the The first bevel gear 39 on the side of the driven gear 38 rotates to install the active pillar 391 on the table 1, and the active pillar 391 protrudes from the surface of the table 1, the second bevel gear 392 installed on the bottom end of the active pillar 391, and the second bevel gear 392 is vertically meshed with the first bevel gear 39, two fixed-point cylinders 393 installed in an array on the table 1 and located outside the processing circular dish 2, and the two fixed-point cylinders 393 and the active pillar 391 are distributed in a triangular shape, one end of the three rotating parts 394 respectively installed on the top of the two fixed-point cylinders 393 and the active pillar 391, the other ends of the three rotating parts 394 are respectively connected to the ends of the three pointed parts of the three-way pointed plate 395, the rectangular column 396 installed in the middle of the three-way pointed plate 395, and a plurality of claws 397 installed in a circular array at the bottom end of the rectangular column 396;

[0054] The upper part of the gripper 397 is in the shape of an arc plate, and the end is a plurality of arc-shaped thin strips. The plurality of grippers 397 together form a utensil for holding tea leaves, simulating human hands. After the plurality of grippers 397 hold the tea leaves, the tea leaves are in a ball shape, and then the first motor 31 is driven to directly drive the first pulley 32 to rotate, and the second pulley 35 is driven to rotate through a plurality of belts 36, and the driving gear 37 is driven to rotate through the rotating shaft 34. The driven gear 38 and the first bevel gear 39 are meshed with each other through the meshing of the driving gear 37 and the driven gear 38, so that the driven gear 38 and the first bevel gear 39 are rotated synchronously, and the second bevel gear 392 is driven to rotate under the meshing action, and the active pillar 391 is rotated synchronously, and finally the rotating member 394 on the active pillar 391 is driven to rotate, thereby driving the three-way pointed plate 395 to follow the rotating member 394. The three-way pointed plate 395 moves along a rotating trajectory, and when the three-way pointed plate 395 moves, the other two rotating parts 394 are pushed to rotate on the corresponding fixed-point cylinders 393 respectively, so as to provide support for the three-way pointed plate 395 and ensure its normal movement. The movement of the three-way pointed plate 395 and the gripping of the plurality of claws 397 drive the ball-shaped tea leaves to roll continuously, thereby realizing the kneading of the tea leaves, and when kneading, an irregular kneading path is obtained by controlling the irregular forward and reverse rotation of the first motor 31 to ensure sufficient kneading; at the same time, under the action of the plurality of claws 397, the action of manually kneading the tea leaves is simulated, so that the tea leaves are kneaded in a ball shape, so that while the tea leaves are driven to roll, the tea leaves can also be squeezed and rubbed against each other, thereby promoting the outflow of tea juice and improving the kneading effect.

[0055] Optionally, a plurality of rotating rods 5 and a plurality of swing cylinders 6 are installed in a circular array at the bottom of the rectangular column 396, and the plurality of swing cylinders 6 are respectively located above the plurality of rotating rods 5, and swing plates 7 are respectively installed on the output shafts of the plurality of swing cylinders 6;

[0056] The ends of the plurality of swing plates 7 are respectively hinged to the back sides of the upper parts of the plurality of grippers 397, and the plurality of swing cylinders 6 are driven to swing the plurality of swing plates 7 downward, so that the plurality of grippers 397 are pushed under the hinged action of the swing plates 7 and the upper parts of the grippers 397, thereby realizing the adjustment of the angles of the plurality of grippers 397, enabling the plurality of grippers 397 to close or expand, thereby enabling the circumferential clamping force on the tea leaves between the plurality of grippers 397 to be adjusted, ensuring that the kneading force can be controlled, and maintaining a relatively large opening angle of the plurality of grippers 397 at the initial stage of kneading, so that the tea leaves are in a relatively loose state, that is, the tea leaves are kneaded with a gentle force, and reducing the opening angle of the plurality of grippers 397 at the later stage to strengthen the clamping degree of the tea leaves, that is, the tea leaves are kneaded with a greater force, so that the kneading force can be dynamically adjusted according to the moisture content of the tea leaves, the thickness of the leaves and other characteristics, effectively preventing the occurrence of pressure overload or insufficient pressure, effectively reducing the breakage rate of the leaves and ensuring uniform kneading, ensuring the integrity of the finished tea and the taste of the tea soup.

[0057] Optionally, the controllable kneading device 3 further includes a rack 8 mounted on the side of the rectangular column 396, a bent support plate 9 mounted on the three-way pointed plate 395, a second motor 10 disposed on the bent support plate 9, and a driving gear 11 mounted on the output shaft of the second motor 10, and the driving gear 11 is meshed with the rack 8;

[0058] The rectangular column 396 is slidably inserted on the three-way pointed plate 395;

[0059] The three-way pointed plate 395 is provided with a through groove for the rack 8 to pass up and down, and drives the second motor 10. The driving gear 11 can mesh with the rack 8 to convert the rotational motion into linear motion, thereby driving the rectangular column 396 to move up and down on the three-way pointed plate 395, and causing the heights of the plurality of claws 397 to change accordingly. Then, under the condition that the inner bottom surface of the processing circular dish 2 is used as the reference surface, the vertical pressure on the tea leaves is adjusted, and then, under the joint action of the plurality of swing cylinders 6, a more precise control of the kneading force is obtained, further ensuring that the entire kneading process is completed with an appropriate kneading force.

[0060] Optionally, a groove is formed on the upper part of the plurality of grippers 397, and a first mesh plate 12 is installed at the opening of the plurality of grooves;

[0061] The backs of the upper parts of the plurality of the grippers 397 are respectively connected to the first air supply pipes 13, and the plurality of the first air supply pipes 13 are respectively connected to the grooves on the plurality of the grippers 397;

[0062] The other ends of the plurality of first air ducts 13 are connected to the air outlet of the first external blower. Specifically, the plurality of first air ducts 13 are connected to the air outlet of the first external blower through a main pipeline. The first external blower is started in time during the kneading process, and the first external blower starts to blow air. The air is diverted through the plurality of first air ducts 13 and input into the grooves on the plurality of grippers 397, and finally blown out through the plurality of first mesh plates 12. Since the plurality of grippers 397 hold the tea leaves, the air coming out of the plurality of first mesh plates 12 will blow on the clumped tea leaves, thereby using the air to cool the tea leaves regularly or irregularly, ensuring that the temperature of the tea leaves is controlled within an optimal range, effectively preventing the tea leaves from generating heat due to friction during the kneading process, which causes a sudden rise in local temperature and accelerates the non-enzymatic oxidation of polyphenols, ensuring that the fermentation degree of the tea leaves is controlled within an appropriate range, and preventing the tea leaves from deviating from the target flavor of light semi-fermentation.

[0063] Optionally, the block unblocking and closing mechanism 4 includes a movable through slot opened in the middle of the rectangular column 396, a first electric push rod 41 invertedly installed on the top of the rectangular column 396, a connecting bar 42 connected to the output shaft of the first electric push rod 41, a hollow tube 43 connected to the side of the connecting bar 42, and the hollow tube 43 is hidden in the movable through slot, a plurality of external release holes 44 are circumferentially opened on the lower end of the hollow tube 43, and a second air supply pipe 45 with one end inserted into the rectangular column 396 along the movable through slot and connected to the hollow tube 43;

[0064] The other end of the second air delivery pipe 45 is connected to the air nozzle of an external high-pressure air pump. After continuous kneading for a period of time, the first motor 31 is stopped to stop the three-way pointed plate 395, and the angles of the plurality of grippers 397 are opened to the maximum through the plurality of swing cylinders 6 to release the grip of the tea leaves, and the rectangular column 396 is pulled up through the second motor 10 until the plurality of grippers 397 leave the internal space of the processing dish 2, and then the first electric push rod 41 is driven to push the connecting strip 42 and the hollow tube 43 downward until the hollow tube 43 is inserted into the ball-shaped The hollow tube 43 is placed inside the tea leaves and contacts the inner bottom surface of the processing circular dish 2, and then the external high-pressure air pump is started to eject high-pressure airflow, and then the airflow enters the hollow tube 43 under the transportation of the second air duct 45, and finally ejects outward from a plurality of external release holes 44, forming fine high-pressure air columns that burst out in all directions inside the tea leaves, thereby scattering the tea leaves, making each piece of tea leaves as independent and loose as possible, and rapidly reducing the temperature of each piece of tea leaves, thereby preventing the tea leaves from being pulled together to cause a stuffy taste, and achieving the de-blocking of clumping tea leaves.

[0065] Optionally, the deblocking and re-closing mechanism 4 further comprises a plurality of arc-shaped driving and pushing plates 46 circumferentially arranged on the side wall of the processing circular dish 2, a plurality of cushion blocks 47 arranged on the table 1, and a plurality of second electric push rods 48 respectively arranged on the plurality of cushion blocks 47, and the output ends of the plurality of second electric push rods 48 are respectively connected to the backs of the plurality of arc-shaped driving and pushing plates 46. After the deblocking is completed, the plurality of second electric push rods 48 are driven to push the plurality of arc-shaped driving and pushing plates 46 forward so that the plurality of arc-shaped driving and pushing plates 46 are gradually gathered together. In the process of the plurality of arc-shaped driving and pushing plates 46 being gathered together, the scattered The tea leaves are pushed to move, and after the several arc-shaped driving plates 46 are closed, the tea leaves can be gathered at a suitable position again, so that the tea leaves can be restored to a clumping shape, and the several claws 397 can hold the tea leaves again for kneading. In the process of the tea leaves being deblocked and re-gathered, the angle and position of each tea leaf are changed, thereby realizing the simulation of the "flip-deblock-re-kneading" action of manual kneading, so as to enrich the kneading mode, increase the mechanical shear force on the tea leaves, and then improve the tightness of the tea leaves, help the efficient release of aroma substances, and improve the production quality of semi-fermented tea.

[0066] Optionally, the deblocking and reclosing mechanism 4 further includes a plurality of arc grooves 49 circumferentially mounted on the side wall of the processing circular dish 2, and the opening ends of the plurality of arc grooves 49 are flush with the inner side wall of the processing circular dish 2, a plurality of second mesh plates 491 respectively mounted at the openings of the plurality of arc grooves 49, a plurality of inlet channels 492 respectively connected to the plurality of arc grooves 49 from the back, and a plurality of third air delivery pipes 493 whose one ends are respectively connected to the plurality of inlet channels 492;

[0067] The other ends of the third air delivery pipes 493 are connected to the air outlet of the second external blower;

[0068] The arc grooves 49 are respectively located in the gaps between the arc driving plates 46. Specifically, the third air ducts 493 are connected to the air outlet of the second external blower through a main pipeline. Before the tea leaves are gathered, the second external blower is started first to allow the wind to blow out through the second mesh plates 491, thereby pushing the tea leaves in front of the second mesh plates 491 forward, and preliminarily completing the gathering of the tea leaves, ensuring that the tea leaves are blown as much as possible onto the movement routes of the arc driving plates 46, thereby ensuring that the subsequent arc driving plates 46 can push the tea leaves to gather, to prevent the tea leaves from being gathered only by the arc driving plates 46, resulting in many tea leaves still being scattered and not being gathered, and to prevent incomplete kneading.

[0069] Optionally, the bottom end of the hollow tube 43 is sharp, ensuring that when the hollow tube 43 is inserted into the tea leaves, the sharp portion can push the tea leaves away to a certain extent, allowing the rear cylindrical portion to enter the interior of the tea leaves, so as to prevent the tea leaves from being crushed and damaged.

[0070] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
