Description

Technical Field

[0001] The invention relates to the technical field of black tea processing, in particular to a processing device and a processing method of cimicifuga leaf black tea. Background Art

[0002] During the black tea processing process, the picked tea leaves need to be fermented. Fermentation is a key process to form the color, aroma and taste quality characteristics of black tea. Fermentation must meet the required appropriate temperature, humidity and oxygen. In the prior art, the rolled leaves are generally placed in a fermentation frame or a fermentation cart, and then placed in a fermentation room for fermentation; Cimicifuga leaf black tea combines the characteristics of Cimicifuga leaf and black tea, and has a unique aroma and taste. Cimicifuga leaf black tea has the effects of black tea in refreshing the mind, relieving fatigue, and cleaning the mouth. At the same time, Cimicifuga leaf itself also has certain medicinal value, but the specific effect depends on the type and content of Cimicifuga leaf.

[0003] At present, when a fermentation device for black tea processing is used, in order to meet the heat dissipation and ventilation of the tea leaves during the fermentation of black tea, the tea leaves need to be stirred to improve their heat dissipation and ventilation effects. A fermentation device for black tea processing is proposed in Chinese Patent Publication No.: CN114831194B, which belongs to the technical field of black tea processing devices. A fermentation device for black tea processing includes a base and a support frame, and also includes: a holding component, a support plate, a driving component, a turning component, and a water replenishing component. Through the provided driving component and turning component, the driving component enables the turning component to start the tea leaves in the holding component to achieve mixing of the tea leaves.

[0004] After the tea leaves are placed in the fermentation frame, the fermentation frame is driven to rotate by a motor and a belt. During this process, the rotation amplitude of the fermentation frame increases, so that the originally flat tea leaves are gathered at the same end inside the fermentation frame. If the tea leaves are stirred and mixed mechanically at this time, the tea leaves may be easily crushed. Alternatively, when the tea leaves are turned and mixed by shaking and flipping back and forth, the bottom layer of tea leaves and the upper layer of tea leaves cannot be evenly mixed like stirring, resulting in uneven wetting of the tea leaves in the later stage. Summary of the invention

[0005] The present invention provides a processing device for Cimicifuga leaf black tea, wherein the tea leaves are isolated by a carrying cloth, and a toggle plate protects and turns the tea leaves by indirectly toggling the tea leaves on the carrying cloth, and a counterweight ring slides along a guide rod under the action of gravity, so that the top of the toggle plate evenly lays the accumulated tea leaves toward the sinking end of the guide rod, thereby solving the problems raised in the above-mentioned background technology, namely: Tea leaves are easily crushed by mechanical mixing, and the mixed tea leaves cannot be evenly moistened.

[0006] To achieve the above-mentioned purpose, the processing device of the Cimicifuga leaf black tea comprises a fermentation vehicle and a placement frame rotatably arranged with the fermentation vehicle, wherein a carrying cloth and a guide rod are fixedly arranged in sequence from top to bottom in the placement frame, the guide rod presents a posture of one end being tilted up and the other end being sunken, a toggle mechanism is slidably arranged on the guide rod, the carrying cloth is used to separate the tea leaves to be fermented from the toggle mechanism, and when the placement frame rotates counterclockwise, the toggle mechanism is used to slide along the trajectory of the guide rod to overturn the tea leaves accumulated on the end of the carrying cloth, and a shielding mechanism is provided on the placement frame outside the tilted end of the guide rod, the shielding mechanism is used to form an obstacle for the tea leaves overturned by the toggle mechanism to limit the tea leaves from escaping from the placement frame, and when the placement frame rotates clockwise, the toggle mechanism uses gravity to evenly spread the accumulated tea leaves on the carrying cloth, and cooperates with a wetting mechanism for replenishing water for the tea leaves provided on the placement frame to realize the work of replenishing water for the tea leaves.

[0007] The toggle mechanism comprises a toggle plate and a counterweight ring, wherein the toggle plate is penetrated by the guide rod and is slidably arranged with the guide rod, and the counterweight ring is fixedly arranged at the bottom of the toggle plate; Under normal conditions, the top of the toggle plate is slightly lower than the end of the carrying cloth. When the placement frame rotates counterclockwise, the tea leaves on the carrying cloth accumulate to one side, causing the bottom of the carrying cloth to sag downward. The toggle plate is used to overturn the carrying cloth at the sag to mix the tea leaves evenly.

[0008] In the above technical solution, the tea leaves piled on the end of the supporting cloth are mainly overturned by the toggle plate, so that the tea leaves on the supporting cloth are scattered and then piled together again, so as to achieve mixing of the tea leaves, which is convenient for even wetting of the tea leaves when they are spread flat later. Secondly, during the reverse movement of the toggle plate, the toggle plate extends into the recessed supporting cloth and evenly spreads the accumulated tea leaves on the supporting cloth for even wetting later.

[0009] The second object of the invention is to provide a method for processing a Cimicifuga leaf black tea, comprising the following steps: S1. After placing tea leaves on the carrier cloth, the placing frame is driven by a motor and a belt to rotate counterclockwise. During this process, as the rotation amplitude of the placing frame increases, the tea leaves at the lower end of the guide rod slide toward the raised end, so that the originally flat tea leaves gather at the same end of the carrier cloth; S2. After the tea leaves are piled up on the carrier cloth, the tea leaves to be stirred are isolated from the paddle plate by the carrier cloth, so as to protect the tea leaves and prevent the paddle plate from directly contacting the tea leaves; S3, the toggle plate slides from the sinking end to the tilting end of the guide rod under the action of gravity, so that the distance between the top of the toggle plate and the carrying cloth is gradually reduced until it contacts the bottom of the carrying cloth and indirectly overturns the tea leaves accumulated on the carrying cloth; S4. When the placement frame rotates to a horizontal position, the counterweight ring slides along the guide rod using gravity. During this process, the top of the toggle plate spreads the accumulated tea leaves toward the sinking end of the guide rod, and the distance between the top of the toggle plate and the carrying cloth gradually decreases, so that when the toggle plate moves to the sinking end, tea leaves are evenly spread on the carrying cloth for later wetting.

[0010] Compared with the prior art, the present invention has the following beneficial effects: 1. After the tea leaves are piled up on the carrier cloth, the carrier cloth is used to isolate the tea leaves to be stirred from the paddle plate, so as to protect the tea leaves and prevent the paddle plate from directly contacting the tea leaves. At the same time, the paddle plate slides from the sinking end to the tilting end of the guide rod under the action of gravity, so that the distance between the top of the paddle plate and the carrier cloth is gradually reduced until it contacts the bottom of the carrier cloth and indirectly overturns the tea leaves piled up on the carrier cloth. The tea leaves on the carrier cloth are rolled over and scattered and piled up again, so as to achieve mixing of the tea leaves and facilitate uniform wetting of the tea leaves in the later stage.

[0011] When the placement frame rotates to a horizontal position, the top of the toggle plate extends into the accumulated tea leaves, and the counterweight ring slides along the guide rod under the action of gravity. In this process, the top of the toggle plate spreads the accumulated tea leaves toward the sinking end of the guide rod, and the distance between the top of the toggle plate and the supporting cloth gradually decreases, so that when the toggle plate moves to the sinking end, the tea leaves are evenly spread on the supporting cloth for later wetting.

[0014] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0015] In view of the problems that during the stirring process of tea fermentation, the mechanical stirring force of tea is not accurate, which easily causes the tea leaves to be broken, affecting the quality of the tea leaves, and the labor intensity of manual stirring is high, which easily causes the tea leaves to be unevenly stirred, resulting in thick tea leaves covering some areas, affecting the heat dissipation and ventilation of the tea leaves, the present invention provides a processing device for Cimicifuga leaf black tea, see Figures 1 - 3 As shown, the fermentation vehicle 100 and the placing frame 110 are rotatably arranged with the fermentation vehicle 100, wherein the placing frame 110 is driven to rotate by a belt and a motor, which belongs to the prior art and is not shown in the figure, and when the tea leaves are turned in the placing frame 110, the placing frame 110 rotates counterclockwise, on the contrary, when the tea leaves are turned over, the placing frame 110 rotates clockwise, and the specific rotation direction of the placing frame 110 is referred to Figure 6 As shown by the arrow q; Secondly, the placing frame 110 is fixed with a carrying cloth 111 and a guide rod 112 from top to bottom, and the guide rod 112 is tilted at one end and sunk at the other end (refer to Figure 4As shown), a toggle mechanism 130 is slidably provided on the guide rod 112, and the carrying cloth 111 is used to separate the tea leaves to be fermented from the toggle mechanism 130. When the placement frame 110 rotates counterclockwise, the toggle mechanism 130 is used to slide along the trajectory of the guide rod 112 to overturn the tea leaves piled up at the end of the carrying cloth 111. A shielding mechanism 140 is provided on the placement frame 110 outside the tilted end of the guide rod 112. The shielding mechanism 140 is used to form an obstacle to the tea leaves overturned by the toggle mechanism 130 to limit the tea leaves from escaping from the placement frame 110, and when the placement frame 110 rotates clockwise, the toggle mechanism 130 uses gravity to evenly spread the accumulated tea leaves on the carrying cloth 111, and cooperates with the wetting mechanism 120 for replenishing water for the tea leaves provided on the placement frame 110 to realize the work of replenishing water for the tea leaves.

[0016] First, when tea leaves have not been added to the carrier cloth 111, the toggle mechanism 130 is located at the sinking end of the guide rod 112. Therefore, based on the above diagram, the following is combined with Figure 4 As shown, the specific structure of the toggle mechanism 130 is shown. The toggle mechanism 130 includes a toggle plate 131 and a counterweight ring 132. The toggle plate 131 is penetrated by the guide rod 112 and is slidably arranged with the guide rod 112. The counterweight ring 132 is fixedly arranged at the bottom of the toggle plate 131 to increase the overall counterweight of the toggle plate 131. Secondly, under normal conditions, the top of the toggle plate 131 is slightly lower than the end of the carrying cloth 111. When the placement frame 110 rotates counterclockwise, under the action of gravity, the tea leaves on the carrying cloth 111 are accumulated to one side, causing the bottom of the carrying cloth 111 to be concave downward. The toggle plate 131 is used to overturn the carrying cloth 111 at the concave position to mix the tea leaves evenly.

[0017] That is to say, after placing tea leaves on the carrier cloth 111, the placing frame 110 is driven by the motor and the belt to rotate counterclockwise. During this process, as the rotation amplitude of the placing frame 110 increases, the tea leaves at the lower end of the guide rod 112 slide toward the raised end, so that the originally flat tea leaves are gathered at the same end of the carrier cloth 111. If the tea leaves are stirred and mixed mechanically at this time, the tea leaves are easily crushed. Or, if the tea leaves are mixed by shaking and flipping back and forth, the tea leaves at the bottom layer and the tea leaves at the upper layer cannot be evenly mixed as by stirring. Therefore, after the tea leaves are piled up on the carrying cloth 111, the carrying cloth 111 is used to isolate the tea leaves to be stirred from the toggle plate 131, so as to protect the tea leaves and prevent the toggle plate 131 from directly contacting the tea leaves. At the same time, the toggle plate 131 slides from the sinking end to the tilting end of the guide rod 112 under the action of gravity, so that the distance between the top of the toggle plate 131 and the carrying cloth 111 is gradually reduced until it contacts the bottom of the carrying cloth 111 and indirectly overturns the tea leaves piled up on the carrying cloth 111. Figure 6As shown, arrow e indicates the direction of movement of the toggle plate 131. The dashed line part shows the state of the bearing cloth 111 after the tea leaves are piled up. Arrow f indicates the direction in which the tea leaves are scattered and moved when the toggle plate 131 comes into momentary contact with the bearing cloth 111 in the piled-up state. After the tea leaves on the bearing cloth 111 are scattered, they are piled up again, thereby realizing the mixing of the tea leaves and facilitating uniform wetting when the tea leaves are laid flat later.

[0018] In addition, considering that after the tea leaves piled up on the bearing cloth 111 are scattered, the impacted tea leaves will splash outward along the inner wall of the placement frame 110. Thus, a convex block 133 is fixedly arranged on one side of the toggle plate 131 pointing to the upturned end of the guide rod 112. When the toggle plate 131 slides to the upturned end of the guide rod 112, there is an opening corresponding to the convex block 133 on the side wall of the placement frame 110. In this way, the convex block 133 extends out from the opening and exerts pressure on the shielding mechanism 140 outside the placement frame 110 to use the shielding mechanism 140 to restrict the scattered tea leaves.

[0019] Next, on the basis of Figure 6 and in combination with Figure 5 As shown, the structure of the shielding mechanism 140 is shown. The shielding mechanism 140 includes a metal plate 141 with one end extending into the placement frame 110 and the other end bent upward and in an "L" shape. Among them, the metal plate 141 can be curled and deformed. A guide block 114 is attached to the bent position of the metal plate 141. The guide block 114 is fixedly arranged between the outer wall of the placement frame 110 and is used to guide the metal plate 141 so that the end of the metal plate 141 extends into the placement frame 110 and appears on the movement path of the tea leaves to form an interception barrier for the tea leaves. The scattered tea leaves will also be blocked by the extended metal plate 141 when moving, and the intercepted tea leaves will form a pile again under the action of gravity; On the other hand, the shielding mechanism 140 further includes a slide rod 142 fixedly arranged at one end of the metal plate 141. A compression spring 144 is elastically arranged between the slide rod 142 and the placement frame 110. The slide rod 142 penetrates through a convex ring fixedly arranged outside the placement frame 110, and the slide rod 142 is slidably arranged with the convex ring. A wedge block 143 corresponding to the opening is fixedly arranged at the bottom of the slide rod 142.

[0020] Specifically, during operation: during the rotation of the placing frame 110, the toggle plate 131 and the protrusion 133 move synchronously, and the tea leaves slide toward the tilted end of the guide rod 112 under the action of gravity. Since the distance between the toggle plate 131 and the carrying cloth 111 gradually decreases during the movement, when there are tea leaves that have not slid to the tilted end on the carrying cloth 111, the toggle plate 131 plays an auxiliary role at this time, and drives the tea leaves on the carrying cloth 111 to the tilted end of the guide rod 112, and when the toggle plate 131 is about to move to the tilted end of the guide rod 112, the toggle plate 131 overturns the tea leaves accumulated on the carrying cloth 111, and the tea leaves that are toggle The tea leaves scattered by the movable plate 131 move outward along the inner wall of the placement frame 110. At the same time, the protrusion 133 applies pressure to the wedge block 143, so that the slide rod 142 drives one end of the metal plate 141 to move downward. The metal plate 141 extends into the placement frame 110 under the guidance of the guide block 114, thereby intercepting the scattered tea leaves. Moreover, compared with the tea leaves that are not intercepted, the intercepted tea leaves are equivalent to being blocked and scattered again, and can be more evenly covered on the carrying cloth 111, while the tea leaves that are not intercepted are covered by natural falling, and their coverage range is small.

[0021] In addition, in order to slow down the sliding speed of the toggle plate 131 so that the toggle plate 131 can be turned over again after the tea leaves are piled up, the toggle plate 131 is turned over again. Figure 4 Combined with Figure 7 As shown, a through groove 113 is provided on the side wall of the placement frame 110 near the guide rod 112, and a rubber block 150 and a slider 151 are slidably arranged in the through groove 113. The rubber block 150 is triangular and bonded to the slider 151. When the toggle plate 131 just starts to slide, the slider 151 is used to slow down the movement speed of the toggle plate 131, that is, the side of the toggle plate 131 will first contact the rubber block 150, and the rubber block 150 increases the friction between the rubber block 150 and the toggle plate 131, and the toggle plate 131 applies pressure to the rubber block 150 to make it move outward.

[0022] Because a bracket plate 152 is rotatably provided on one side of the slider 151, the other end of the bracket plate 152 extends to the side of the fermentation cart 100, a return spring 153 is elastically connected between the bracket plate 152 and the fermentation cart 100, and an auxiliary rod 101 is rotatably provided on the bracket plate 152. The auxiliary rod 101 is fixedly arranged between the fermentation cart 100, and the auxiliary rod 101 is concentrically arranged with the placement frame 110. Therefore, when the placement frame 110 rotates, the bracket plate 152 can rotate concentrically with it. When the bracket plate 152 moves outward, the auxiliary rod 101 maintains its stability during movement. At the same time, the return spring 153 is stretched and its elastic potential energy increases. As the displacement of the rubber block 150 increases, when the toggle plate 131 slides over the rubber block 150, the rubber block 150 is reset under the elastic action of the return spring 153.

[0023] Further, combined with Figure 8 , Figure 9 , Figure 10 As shown, the wetting mechanism 120 includes an air cushion 121 and a pump body, the pump body is connected to a water tank and a hose, the air cushion 121 is located on the path of the bracket plate 152 moving outward, the air cushion 121 is connected to a water supply pipe 122 fixed on the fermentation vehicle 100 through a hose, and nozzles are arranged at intervals on the water supply pipe 122; An outer ring 124 is provided on the water supply pipe 122 between each nozzle, and a sponge 125 is accommodated in the outer ring 124 for wiping water stains on the water supply pipe 122 . A plurality of outer rings 124 are fixedly provided with a bending plate 123 , one end of which is bent downward and bonded to the air cushion 121 .

[0024] Working principle: When the toggle plate 131 slides from the tilted end to the sinking end of the guide rod 112 (refer to Figure 4 As shown in FIG. 1 ), that is, the placing frame 110 rotates clockwise to reset. When the placing frame 110 rotates to a horizontal position, the top of the toggle plate 131 extends into the accumulated tea leaves, and the counterweight ring 132 slides along the guide rod 112 by gravity. In this process, the top of the toggle plate 131 spreads the accumulated tea leaves toward the sinking end of the guide rod 112, and the distance between the top of the toggle plate 131 and the carrying cloth 111 gradually decreases, so that when the toggle plate 131 moves to the sinking end, tea leaves are evenly spread on the carrying cloth 111 for later wetting. At the same time, when the toggle plate 131 moves in the opposite direction to contact the rubber block 150, the pump body starts to supply water into the hose. At this time, the rubber block 150 is pushed outward by the toggle plate 131. The process is as described above and will not be repeated here. The end of the bracket plate 152 squeezes the air cushion 121, so that the cross-sectional area of ​​the air cushion 121 is reduced, and the flow rate of the water flowing through the air cushion 121 is increased, so that the water mist sprayed from the nozzle is more evenly covered on the tea leaves on the carrier cloth 111, thereby achieving the wetting of the tea leaves; Furthermore, since the hose has a certain elasticity, when the support plate 152 applies pressure to the air cushion 121, the air cushion 121 will also drive the bending plate 123 to move to one side. During this process, the sponge 125 slides over the water supply pipe 122 to absorb the attached water stains, thereby reducing the residual water stains on the water supply pipe 122 and improving the uniformity of wetting the tea leaves. Moreover, when the hose is reset, the sponge 125 can slide over the water supply pipe 122 again to absorb the water stains on the water supply pipe 122 through reciprocating movement.

[0025] In summary, this embodiment also provides a processing method of a Cimicifuga leaf black tea processing device, comprising the following method steps: S1. After placing tea leaves on the carrier cloth 111, the placing frame 110 is driven by a motor and a belt to rotate counterclockwise. During this process, as the rotation amplitude of the placing frame 110 increases, the tea leaves at the lower end of the guide rod 112 slide toward the raised end, so that the originally flat tea leaves are gathered at the same end of the carrier cloth 111. S2, after the tea leaves are piled up on the carrier cloth 111, the tea leaves to be stirred are isolated from the paddle plate 131 by the carrier cloth 111, so as to protect the tea leaves and prevent the paddle plate 131 from directly contacting the tea leaves; S3, the toggle plate 131 slides from the sinking end to the tilting end of the guide rod 112 under the action of gravity, so that the distance between the top of the toggle plate 131 and the carrying cloth 111 is gradually reduced, until it contacts the bottom of the carrying cloth 111 and indirectly overturns the tea leaves accumulated on the carrying cloth 111; S4. When the placement frame 110 rotates to a horizontal position, the counterweight ring 132 slides along the guide rod 112 by gravity. During this process, the top of the toggle plate 131 spreads the accumulated tea leaves toward the sinking end of the guide rod 112, and the distance between the top of the toggle plate 131 and the carrier cloth 111 gradually decreases, so that when the toggle plate 131 moves to the sinking end, tea leaves are evenly spread on the carrier cloth 111 for later wetting.

The processing device of Cimicifuga leaf black tea according to claim 6, characterized in that: The wetting mechanism (120) comprises an air cushion (121) and a pump body, wherein the pump body is connected to a water tank and a hose, wherein the air cushion (121) is located on a path for the support plate (152) to move outwards, and wherein the air cushion (121) is connected to a water supply pipe (122) fixed on the fermentation vehicle (100) via a hose, and nozzles are arranged at intervals on the water supply pipe (122).

9. The processing device of Cimicifuga leaf black tea according to claim 8, characterized in that: An outer ring (124) is sleeved on the water supply pipe (122) between each nozzle, and a sponge (125) is accommodated in the outer ring (124) for wiping water stains on the water supply pipe (122). A plurality of outer rings (124) are fixedly provided with a bending plate (123), and one end of the bending plate (123) is bent downward and bonded to the air cushion (121).

10. A method for operating the processing device for producing Cimicifuga leaf black tea as claimed in claim 3, characterized in that: The method comprises the following steps: S1, after placing tea leaves on the carrier cloth (111), the placing frame (110) is driven by a motor and a belt to rotate counterclockwise. During this process, as the rotation amplitude of the placing frame (110) increases, the tea leaves at the lower end of the guide rod (112) slide toward the raised end, so that the tea leaves originally laid flat gather at the same end of the carrier cloth (111); S2, after the tea leaves are piled up on the carrier cloth (111), the carrier cloth (111) is used to isolate the tea leaves to be stirred from the stirring plate (131), thereby protecting the tea leaves and preventing the stirring plate (131) from directly contacting the tea leaves; S3, the toggle plate (131) slides from the sinking end to the tilting end of the guide rod (112) under the action of gravity, so that the distance between the top of the toggle plate (131) and the supporting cloth (111) gradually decreases until the toggle plate (131) contacts the bottom of the supporting cloth (111) and indirectly overturns the tea leaves accumulated on the supporting cloth (111); S4. When the placement frame (110) is rotated to a horizontal position, the counterweight ring (132) slides along the guide rod (112) by the action of gravity. During this process, the top of the toggle plate (131) spreads the accumulated tea leaves toward the sinking end of the guide rod (112), and the distance between the top of the toggle plate (131) and the supporting cloth (111) gradually decreases, so that when the toggle plate (131) moves to the sinking end, tea leaves are evenly spread on the supporting cloth (111) for later wetting.
