Description

Technical Field

[0001] The present invention relates to the technical field of green tea processing, and specifically to a pre-treatment device for green tea processing for fixation. Background Art

[0002] Fixation of green tea is a pre-treatment process in green tea production. Fixation is to destroy and inactivate the oxidase activity in fresh leaves through high temperature, inhibit the enzymatic oxidation of tea polyphenols and other substances in fresh leaves, evaporate part of the water in fresh leaves, make the tea leaves soft, facilitate rolling into shape, and at the same time emit the green smell and promote the formation of good aroma. The existing green tea fixation methods usually include mechanical fixation and manual fixation. Mechanical fixation is suitable for large-scale production, while manual fixation has a small output and requires two processes of primary frying and secondary frying.

[0003] Existing green tea fixation usually directly fries fresh leaves without washing. In terms of the tea-making process, washing fresh leaves will increase the water content in fresh leaves, and at the same time take away the aroma and minerals in fresh leaves. The increase in the water content of fresh leaves will increase the difficulty of subsequent fixation. If the water in fresh leaves does not evaporate sufficiently, the tea leaves are prone to mildew and deterioration, and at the same time the taste of the tea will become lighter, the number of brewing times will decrease, and thus the quality of the tea will be affected. After the tea leaves are picked, if they are directly fixed, there is also a possibility of bringing impurities in the tea leaves, and at the same time the water on the surface of fresh leaves cannot be removed. Therefore, the commonly used method is to manually select the fresh leaves once and further spread the fresh leaves flat for 2 - 3 hours, and then perform fixation. Therefore, manual selection takes a lot of time, and the flattened fresh leaves also occupy a large amount of space, and spreading them flat also wastes a lot of time. Therefore, a pre-treatment device for green tea fresh leaves before fixation is needed. Summary of the Invention

[0004] The purpose of the present invention is to provide a pre-treatment device for green tea processing for fixation, so as to solve the related problems of selecting and spreading fresh leaves flat during the processing of green tea fresh leaves as mentioned in the above background art.

[0005] To achieve the above purpose, the present invention provides the following technical solutions: It includes two groups of installation support plates. At both ends of the bottoms of the two groups of installation support plates, support legs are provided.

In the middle of the outer side of the transmission shaft A, two cams are symmetrically provided. On the side of the feeding hopper close to the transmission shaft A, an arc-shaped block adapted to the cam is provided. By providing the feeding bin member, the fresh green tea leaves in the feeding hopper can be stably output and evenly spread on the top of the screening mesh plate to prevent the accumulation of fresh green tea leaves.

[0008] Preferably, the air blower member includes two intake fans arranged at the bottoms of the two groups of mounting support plates. The output ends of the intake fans are provided with air delivery pipes. At the ends of the bottoms of the two groups of mounting support plates close to the intake fans, an exhaust port is jointly provided. The ends of the two air delivery pipes far from the intake fans are communicated with the bottom of the exhaust port. By providing the air blower member, the blowing of the fresh green tea leaves by the natural wind outside is simulated to accelerate the air circulation, so that the moisture on the surface of the fresh green tea leaves evaporates faster, improving the existing flattening and drying method and reducing the space occupation requirement.

[0009] Preferably, pulley sets A are jointly arranged at both ends of the transmission shaft C and the transmission shaft D. At the position below the feed hopper, a transmission shaft B passing through the two installation support plates is arranged between the two groups of installation support plates. Pulley sets D are jointly arranged at both ends of the transmission shaft B and the transmission shaft C.

[0010] Preferably, transmission shafts E extending to the outside are arranged in the middle of the intake fans. Pulley sets B are jointly arranged on the outer sides of the two transmission shafts E and at both ends of the transmission shaft D. Impellers are arranged inside the intake fans, and an air inlet protective net cover is arranged at one end of the front of the intake fans.

The height of the bottom of the feed hopper is higher than the height of the top of the screening mesh plate. The exhaust port is located at the bottom of the screening mesh plate away from the feed hopper. By the distance between the installation support plates being greater than the width of the screening mesh plate, the requirement for the horizontal displacement space of the screening mesh plate in the transverse direction is ensured. And by the position height of the exhaust port being lower than the screening mesh plate, the fresh green tea leaves output by the screening mesh plate are suspended and blown, improving the water evaporation efficiency.

[0012] Preferably, the position height of the input end of the installation support plate and the screening mesh plate is higher than that of its output end, and the horizontal included angle at both ends is 5 degrees. Through the inclined surface structure design of the screening mesh plate, the normal falling of the fresh green tea leaves is realized, and the function of conveying is realized while screening.

[0013] Compared with the prior art, the present invention provides a pre - killing pretreatment device for green tea processing, having the following beneficial effects:

[0014] 1. The present invention drives the cylindrical displacement groove to rotate through the rotation of the transmission shaft C. Through the rotation of the cylindrical displacement groove, the guide rod inside it follows to perform horizontal reciprocating displacement, thereby driving the screening mesh plate at the top of the guide rod to perform horizontal reciprocating displacement. At the same time, it drives the support slider at the bottom of the screening mesh plate to slide reciprocally inside the chute A, so as to screen the fresh leaves on the top of the screening mesh plate, remove the impurities in the fresh leaves, and at the same time cooperate with the airflow ejected from the exhaust port to simulate natural wind blowing on the fresh leaves, thereby enabling the moisture on the surface of the green tea fresh leaves to evaporate, optimizing the existing step of laying flat, and improving the production efficiency of green tea;

[0015] 2. The present invention utilizes the transmission shaft A to rotate under the action of transmission, drives the cam to rotate and squeeze the feed hopper on one side of the arc-shaped block to perform longitudinal displacement, and is equipped with a connecting slider sliding inside the chute B and squeezing the spring B to generate a rebounding force, so that the feed hopper performs longitudinal reciprocating displacement, thereby ensuring that the fresh leaves inside the feed hopper will not accumulate, enabling the green tea fresh leaves to be evenly spread on the top of the screening mesh plate from the output end of the feed hopper, and ensuring the function of selecting fresh leaves;

[0016] 3. The present invention drives the impeller inside the intake fan under the driving force of the pulley group B, conveys the external airflow to the position of the exhaust port through the air delivery pipe and ejects it, thereby realizing the function of naturally drying the fresh leaves discharged from the output end of the screening mesh plate by blowing, accelerating the air circulation, making the evaporation speed of the moisture on the surface of the fresh leaves faster, and accelerating the production efficiency of the fresh leaves.

[0026] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0027] Embodiment 1:

[0028] Please refer to Figure 1-8 , the present invention provides a technical solution: a pre-treatment equipment for green tea fixation, including two groups of installation support plates 1. Support legs are provided at both ends of the bottoms of the two groups of installation support plates 1. Transmission shafts C 14 and D 31 that penetrate the two groups of installation support plates 1 are provided at both ends of the sides where the two groups of installation support plates 1 are close to each other. Reciprocating displacement members are provided on the outer sides of the two groups of transmission shafts C 14 and D 31, and a screening mesh plate 6 is jointly provided on the tops of the two groups of reciprocating displacement members.

[0029] As a preferred solution of this embodiment: The reciprocating displacement member includes two connecting plates 18 disposed at the middle parts of the two ends of the closer sides of the two sets of mounting support plates 1. On the outer sides of the bottoms of the transmission shaft C14 and the transmission shaft D31, two cylindrical displacement grooves 22 are provided. At the two ends of the top of the connecting plate 18, a guiding groove 27 penetrating through the connecting plate 18 is provided. On both sides of the two ends of the bottom of the screening mesh plate 6, guiding rods 23 penetrating through the guiding groove 27 and extending into the interior of the cylindrical displacement groove 22 are provided. At the middle part of the top of the connecting plate 18, a chute A26 is provided. In the middle of the interior of the chute A26, a supporting slider 25 is provided. On both sides of the supporting slider 25, spring A24 connected to the inner wall of the chute A26 is provided. The top of the supporting slider 25 is connected to the bottom of the screening mesh plate 6. By providing the reciprocating displacement member, the function of driving the screening mesh plate 6 to reciprocate horizontally is realized, so that the fresh green tea leaves on its top can follow the displacement to screen the impurities therein.

[0030] As a preferred solution of this embodiment: The distance between the two sets of mounting support plates 1 is greater than the width of the two side edges of the screening mesh plate 6. The height of the bottom of the feed hopper 8 is higher than the position height of the top of the screening mesh plate 6. The exhaust port 5 is located at the bottom of the end of the screening mesh plate 6 away from the feed hopper 8. By the distance between the mounting support plates 1 being greater than the width of the screening mesh plate 6, the requirement for the horizontal displacement space of the screening mesh plate 6 is ensured, and by the position height of the exhaust port 5 being lower than that of the screening mesh plate 6, the fresh green tea leaves output by the screening mesh plate 6 are suspended and blown, improving the water evaporation efficiency.

[0031] As a preferred solution of this embodiment: The position height of the input ends of the mounting support plate 1 and the screening mesh plate 6 is higher than that of their output ends, and the horizontal included angle at both ends is 5 degrees. Through the inclined surface structure design of the screening mesh plate 6, the normal falling of the fresh green tea leaves is realized, and the function of conveying is realized while screening.

[0032] Such as Figure 1 、 2As shown in Figures 3, 5, and 8, when the device is in operation, the driving motor 17 is turned on to drive the rotation of the driving gear 16, which in turn drives the rotation of the driven gear 15 meshing with the driving gear 16. The driven gear 15 drives the rotation of the transmission shaft B12, causing the pulley sets C11 and D13 at both ends of the transmission shaft B12 to rotate accordingly. The pulley set D13 drives the rotation of the transmission shaft C14, and the transmission shaft C14 drives the rotation of the transmission shaft D31 connected to the pulley set A2. The rotation of the transmission shaft C14 and the transmission shaft D31 drives the rotation of the two sets of cylindrical displacement grooves 22 on their outer sides. The rotation of the cylindrical displacement grooves 22 causes the guide rods 23 inside them to be restricted by the guide grooves 27 and perform lateral reciprocating displacement. The displacement of the guide rods 23 drives the lateral reciprocating displacement of the screening mesh plate 6, causing the green tea fresh leaves on the surface of the screening mesh plate 6 to swing, removing impurities in the fresh leaves, and improving the quality of the green tea fresh leaves. Furthermore, the height of the input end of the screening mesh plate 6 is 5 degrees higher than the horizontal height of the output end, causing the fresh leaves to move downward under the influence of gravity while undergoing reciprocating screening, thus realizing the functions of conveying and screening the green tea fresh leaves.

[0033] Embodiment 2:

[0034] The difference from Embodiment 1 is that: at one end of the tops of the two sets of mounting support plates 1, a feed bin body member is jointly provided, and the bottom of the feed bin body member is close to the middle of one end of the top of the screening mesh plate 6.

[0035] As a preferred solution of this embodiment: the feed bin body member includes two sets of support frames B9 provided at the top of one end of the two sets of mounting support plates 1. At the middle of the sides of the two sets of support frames B9 close to each other, sliding grooves B29 are provided. At the middle of the sliding grooves B29, connecting sliders 30 are provided. At both ends of the connecting sliders 30, springs B28 connected to the inner walls of the sliding grooves B29 are provided. At one end of the two sets of connecting sliders 30 close to each other, a feed hopper 8 is jointly provided. At the position of the top of the mounting support plate 1 close to one end of the support frame B9, two sets of support frames A7 are provided. On the side of the two sets of support frames A7 close to each other, a transmission shaft A10 passing through the support frame A7 is jointly provided. At the middle of the outer side of the transmission shaft A10, two sets of cams 21 are symmetrically provided. On one side of the feed hopper 8 close to the transmission shaft A10, an arc-shaped block 20 adapted to the cam 21 is provided. By providing the feed bin body member, the green tea fresh leaves in the feed hopper 8 can be stably output and evenly spread on the top of the screening mesh plate 6, preventing the accumulation of green tea fresh leaves.

[0036] As a preferred solution of this embodiment: Pulley sets A2 are jointly arranged at both ends of transmission shaft C14 and transmission shaft D31. Transmission shaft B12 passing through the two installation support plates 1 is arranged at the position below the feed hopper 8 where the two installation support plates 1 are located. Pulley sets D13 are jointly arranged at both ends of transmission shaft B12 and transmission shaft C14. Pulley sets C11 are jointly arranged at both ends of transmission shaft B12 and transmission shaft A10. An installation plate is arranged inside one installation support plate 1, and a driving motor 17 is arranged at the top of the installation plate. The output end of the driving motor 17 is provided with a driving gear 16, and a driven gear 15 meshing with the driving gear 16 is arranged on the outer side of transmission shaft B12. Through the cooperation of each component, the power transmission function is realized.

[0037] As Figure 1 , 2 , 3, 4, 6 show that when fresh green tea leaves are added to the inside of the feed hopper 8, at this time, the transmission of the pulley set C11 drives the transmission shaft A10 to rotate. The rotation of the transmission shaft A10 drives the cam 21 to rotate and squeeze the feed hopper 8 on one side of the arc-shaped block 20 to perform longitudinal displacement. The displacement of the feed hopper 8 drives the connecting slider 30 to slide inside the chute B29 and compress the spring B28 to generate a rebound force. Through this rebound force, the connecting slider 30 drives the feed hopper 8 to reset, thereby realizing the reciprocating vibration mode of the feed hopper 8, making the fresh leaves inside the feed hopper 8 follow the vibration, avoiding the accumulation of fresh leaves inside the feed hopper 8, improving the practicability of the device, and ensuring the normal feeding of fresh leaves.

[0038] Embodiment 3:

[0039] The difference from Embodiment 1 and Embodiment 2 is that: Wind mechanism components are symmetrically arranged at the bottom of the two installation support plates 1 at the end far from the feed bin body component.

[0040] As a preferred solution of this embodiment: The wind mechanism component includes two intake fans 3 arranged at the bottom of the two installation support plates 1. The output end of the intake fan 3 is provided with an air delivery pipe 19. An exhaust port 5 is jointly arranged at one end of the bottom of the two installation support plates 1 close to the intake fan 3. The ends of the two air delivery pipes 19 far from the intake fan 3 are mutually communicated with the bottom of the exhaust port 5. By setting the wind mechanism component, it simulates the blowing of the external natural wind on the fresh green tea leaves, accelerates the air circulation, and enables the moisture on the surface of the fresh green tea leaves to evaporate faster, improving the existing method of spreading and drying, and reducing the space occupation requirement.

[0041] As a preferred solution of this embodiment: a transmission shaft E extending to the outside is provided in the middle part of the air intake fan 3, and a pulley group B4 is provided on the outer sides of the two groups of transmission shafts E and the two ends of the transmission shaft D31. An impeller is provided inside the air intake fan 3, and an air inlet protection mesh cover is provided at one end of the front of the air intake fan 3. The pulley group A2, the pulley group B4, the pulley group C11 and the pulley group D13 have the same structure, and are all composed of two groups of pulleys and a group of synchronous belts. By providing an impeller, the function of transporting the outside air to the exhaust port 5 for ejection is realized.

[0042] like Figure 1 , 2 As shown in Figures 3 and 7, the pulley group B4 at both ends of the transmission shaft D31 is driven to rotate through the transmission of the pulley group A2, and the impeller inside the air intake fan 3 is driven to rotate through the pulley group B4, so that the airflow outside the air intake fan 3 enters the interior of the air intake fan 3, and is transported to the exhaust port 5 through the air supply pipe 19 and ejected. At this time, the fresh leaves screened by the screening mesh plate 6 are blown by the cold air flow ejected from the exhaust port 5, which accelerates the airflow circulation between the fresh green tea leaves, and then takes away the moisture on the surface, thereby realizing the pretreatment function of the fresh green tea leaves.

[0043] Working principle: by providing the feed hopper 8 with a vibrating effect, the fresh leaves inside the feed hopper 8 will not accumulate inside it, and the fresh green tea leaves can be evenly spread on the top of the screening mesh 6 for screening, and the screening mesh 6 can be laterally moved back and forth so that the fresh green tea leaves on the top can vibrate back and forth, and then the impurities in the fresh leaves can be removed by the screening mesh 6, thereby optimizing the existing manual screening method, and further through the structural design of the inclined surface of the screening mesh 6, the fresh leaves automatically fall to its output end, and the cold air flow sprayed from the exhaust port 5 blows on the fresh green tea leaves, accelerating the evaporation rate of the water on the surface of the fresh leaves, thereby realizing the pre-treatment function of the fresh green tea leaves, optimizing the existing flattening and drying method, reducing the space occupancy rate, and also improving the production efficiency of the fresh green tea leaves, providing preparation for the subsequent withering process.

[0044] Finally, it should be noted that the above content is only used to illustrate the technical solution of the present invention, rather than to limit the scope of protection of the present invention. Simple modifications or equivalent substitutions of the technical solution of the present invention by ordinary technicians in this field do not deviate from the essence and scope of the technical solution of the present invention.
