Description

Technical Field

[0001] The present invention relates to the field of tea processing, and particularly to a tea processing device and method for making Purple Concubine Tea. Background Art

[0002] Purple Concubine Tea is made from specific purple bud tea tree varieties. The young leaves, buds or stems of such tea trees present natural purple, hence the name. Rich in anthocyanins, tea polyphenols, amino acids, etc., it has attracted much attention in the market.

[0003] The processing method of Purple Concubine Tea is similar to that of other tea categories, mainly including steps such as picking, withering, fixation, rolling, fermentation, drying, packaging, etc. Among them, rolling is the core link in shaping the appearance and taste of Purple Concubine Tea, and the rolling force should be appropriately adjusted according to the tenderness of the tea leaves.

[0004] The current mainstream rolling method is to roll the pressing plate in the rolling machine and use pressure and friction to roll Purple Concubine tea leaves. However, during the rolling process of the current rolling machine for tea leaves, the tea leaf cells rupture, and the volume gradually decreases after releasing the juice. The pressure exerted by the pressing plate on the tea leaves is difficult to adjust according to the volume of the tea leaves. As a result, the rolling force gradually decreases, leading to uneven stress on Purple Concubine Tea and poor taste. To ensure the taste and appearance of Purple Concubine Tea, the rolling force needs to be kept uniform.

[0005] Therefore, the present device proposes a tea processing device and method for making Purple Concubine Tea that can automatically adjust the rolling pressure according to the change in the volume of Purple Concubine tea leaves to make them evenly stressed. Summary of the Invention

Detailed implementation manners

[0030] Next, a specific embodiment of the present invention will be elaborated in detail with reference to the attached Figure 1 - attached Figure 7 drawings.

[0031] Referring to the attached Figures 1-7 drawings, a tea processing device and processing method for making Purple Concubine Tea includes a rolling machine 1. A material receiving tray 101 is fixedly connected to the rolling machine 1. A rolling barrel 13 is rotatably connected to the rolling machine 1. The rolling barrel 13 is a barrel shape with an open top and a through hole at the bottom. The bottom of the rolling barrel 13 contacts the material receiving tray 101. Purple Concubine tea leaves (hereinafter collectively referred to as: tea leaves) are put into the rolling barrel 13 from the top and fall onto the material receiving tray 101 through the through hole at the bottom of the rolling barrel 13. A pressing cover 14 with a switch electrically connected to an external power supply is fixedly connected to the rolling barrel 13. Starting the switch controls the up and down movement of the pressing cover 14. The pressing cover 14 is placed at the open top of the rolling barrel 13, aiming to achieve the rolling effect of the tea leaves through the combination of the downward pressing action of the pressing cover 14 and the rotational movement of the rolling barrel 13.

[0032] To achieve the rotational movement of the rolling barrel 13, a motor 11 is installed on the rolling machine 1. The output shaft of the motor 11 is connected to the rolling barrel 13 through a transmission assembly 12, aiming to drive the rolling barrel 13 to perform a circular motion on the material receiving tray 101 through the transmission assembly 12 by the motor 11.

[0033] Considering that directly pressing down the pressing cover 14 may cause uneven stress on the tea leaves, excessive rupture of the cell walls of the leaves, a large amount of tea juice to overflow, increase the broken leaf rate, and affect the integrity and aesthetic appearance of the tea leaf strands. Moreover, as described in the background art, the volume of the tea leaves decreases after being kneaded by the pressing cover 14, and it is difficult for the pressing cover 14 to adjust the kneading pressure according to the change in the volume of the tea leaves, resulting in a gradual decrease in the stress on the tea leaves. Therefore, the following improvements are made to this device: A plurality of support columns 15 are slidably connected to the pressing cover 14. The support columns 15 all penetrate through the pressing cover 14 and extend out of the top of the pressing cover 14. A plurality of support columns 15 are commonly fixedly connected to an adjustable extrusion force airbag 16 at the bottom. The airbag 16 is located at the bottom of the pressing cover 14. A first spring 17 corresponding to the number of support columns 15 is compressed between the airbag 16 and the pressing cover 14. The first spring 17 is wound around the support column 15.

[0034] Before starting, the first spring 17 is in a relaxed state. The pressing cover 14 and the airbag 16 are both placed above the top of the kneading barrel 13. The tea leaves are poured into the kneading barrel 13. Starting the switch drives the pressing cover 14 to move downward, and the airbag 16 moves downward in linkage until it squeezes the tea leaves. Subsequently, the motor 11 is started. Due to the presence of the transmission component 12, the kneading barrel 13, the pressing cover 14, and the airbag 16 all rotate in a circular motion on the material receiving tray 101, thereby realizing the kneading action of the tea leaves.

[0035] When the airbag 16 moves downward to squeeze the tea leaves, the airbag 16 is forced to move upward, the support column 15 moves upward in linkage, and the first spring 17 deforms. As the tea leaves are gradually kneaded by the airbag 16, the volume of the tea leaf cell walls gradually decreases after being broken. To enable the airbag 16 to adjust the extrusion force according to the change in the volume of the tea leaves, this device is provided with an adjustment component on the pressing cover 14 to achieve this. Specifically: One of the support columns 15 is fixedly connected to a first rack 18 on one side outside the top of the pressing cover 14. A first gear 19 is rotatably connected to the top of the pressing cover 14 through a support 191. The first gear 19 meshes with the first rack 18.

[0036] A guide post 151 is also fixedly connected to the top of the gland 14. A telescopic member 115 is slidably connected to the guide post 151. A second rack 110 is fixedly connected to the top of the telescopic member 115. Initially, the second rack 110 is misaligned with the first gear 19. A moving block 111 is fixedly connected to the second rack 110. The moving block 111 is fixedly connected to the output end of the electric push rod 114. A base 1141 is fixedly connected to the electric push rod 114. The bottom of the base 1141 is in contact with the top of the gland 14, aiming to make the electric push rod 114 stable on the gland 14 through the base 1141. A cross bar 113 is fixedly connected to the base 1141. The cross bar 113 passes through the moving block 111 and extends to the outside, aiming that the moving block 111 can slide on the cross bar 113. A limit cap is provided at the end of the cross bar 113. A second spring 112 is compressed between the limit cap and the moving block 111. The fixed end of the telescopic member 115 is slidably connected to the guide post 151. The output end of the telescopic member 115 is fixedly connected to a rack group 117. A third spring 116 is compressed between the telescopic member 115 and the rack group 117. The rack group 117 is provided with parallel double rows of teeth 1171. An extrusion member 118 is also fixedly connected to the rack group 117. An extrusion block 119 is also fixedly connected to the top of the gland 14. The extrusion block 119 is provided with an inclined surface. The extrusion member 118 is in extrusion fit with the inclined surface on the extrusion block 119. The extrusion member 118 is located at the bottom of the inclined surface of the extrusion block 119.

[0037] An air pipe 161 is connected to the air bag 16, aiming to make the air bag 16 expand and form through the air pipe 161, thereby increasing the extrusion force of the air bag 16 on the tea leaves. The air pipe 161 passes through the gland 14 and is connected to an air valve 162 fixedly connected to the gland 14. A second gear 120 is rotatably connected to the air valve 162, aiming to realize the opening of the air valve 162 through the rotation of the second gear 120.

[0038] In the initial state, the second gear 120 is misaligned with the double-row teeth 1171 on the second gear 120. Moreover, under the deformation action of the third spring 116, the second gear 120 is stabilized in the middle of the double-row teeth 1171 on the second gear 120. When the airbag 16 initially moves downward to squeeze the tea leaves, due to the squeezing force, the airbag 16 moves upward by a certain distance, the first spring 17 deforms, and the support 15 and the first rack 18 are controlled to move upward synchronously. The first rack 18 meshes with the first gear 19 to drive the first gear 19 to rotate. Initially, the second rack 110 is misaligned with the first gear 19. The electric push rod 114 is started to drive the moving block 111 to move forward. The second rack 110 and the telescopic member 115 are linked to move forward. Then, the second rack 110 meshes with the first gear 19. Based on the meshing action, the second rack 110 moves upward, driving the telescopic member 115 to move upward on the guide post 151. The rack group 117 and the extrusion member 118 are both controlled to move upward. The extrusion member 118 moves upward to generate extrusion with the extrusion block 119. Due to the existence of the inclined surface on the extrusion block 119, the extrusion member 118 moves forward and then drives the teeth 1171 to move. After the teeth 1171 mesh with the second gear 120, the second gear 120 is driven to rotate. The rotation of the second gear 120 is linked to the opening of the air valve 162. Through the air delivery pipe 161, the airbag 16 is inflated and expanded. Thus, when the squeezing force between the airbag 16 and the tea leaves is increased, the tea leaves are evenly stressed. During this process, the first spring 17 always maintains a deformed state.

[0039] Specifically, the opening action of the air valve 162 linked to the rotation of the second gear 120 lags behind the action of the airbag 16 initially moving downward to squeeze the tea leaves. That is, the opening of the air valve 162 is triggered after the tea leaves are kneaded for a period of time. The purpose is to automatically trigger the air valve 162 to inflate the airbag 16 after the tea leaves are kneaded and their volume decreases, so as to make the airbag 16 maintain a squeezing force equal to the initial state on the tea leaves with reduced volume.

[0040] After the airbag 16 is inflated and expanded, it maintains the kneading action on the tea leaves, and the volume of the tea leaves continues to decrease. The first spring 17 gradually returns to its original position. During the process of the first spring 17 returning to its original position, a constant squeezing force is maintained between the airbag 16 and the tea leaves, and the air valve 162 remains open. The airbag 16 continues to be inflated. Under the combined action of the continuous expansion of the airbag 16 and the return of the first spring 17, the squeezing force on the tea leaves will gradually increase, resulting in excessive fragmentation of the tea leaves, which is not conducive to the taste and the integrity of the appearance. Therefore, in order to achieve uniform stress during the tea leaf kneading process, during the process of the first spring 17 returning to its original position, the air valve 162 should be closed to stop the airbag 16 from expanding.

[0041] As the first spring 17 resets, the airbag 16 moves downward, the pillar 15 and the first rack 18 are controlled to move downward synchronously, the first rack 18 and the first gear 19 are engaged to drive the first gear 19 to rotate in the opposite direction, the second rack 110 is engaged in the opposite direction with the first gear 19, the second rack 110 moves downward, driving the telescopic member 115 to move downward, the rack group 117 and the extrusion member 118 are both controlled to move downward, the extrusion member 118 moves back and forth and drives the individual teeth 1171 to move, the individual teeth 1171 is engaged in the opposite direction with the second gear 120 and drives the second gear 120 to rotate in the opposite direction, the second gear 120 rotates in the opposite direction to close the linkage valve 162, and closes the air supply pipe 161 to inflate the airbag 16, thereby ensuring the effect of uniform force on the tea leaves.

[0042] After the air valve 162 is closed and the first spring 17 is completely reset and in a relaxed state, the airbag 16 squeezes the tea leaves so that the airbag 16 moves up again, and then the first spring 17 is deformed again. Through the meshing of the first rack 18 and the first gear 19, the meshing of the tooth 1171 and the second gear 120 causes the second gear 120 to rotate repeatedly, thereby realizing the alternating opening and closing of the air valve 162, and then realizing that the airbag 16 is continuously inflated according to the reduction in the volume of the tea leaves. Under the action of the first spring 17, the airbag 16 produces an effect of uniform squeezing force on the tea leaves.

[0043] In order to protect the operation of the adjustment component of the airbag 16 from being affected by external factors, a cover 141 is detachably connected to the pressure cover 14 , and the relevant components of the adjustment component are built into the cover 141 .

[0044] Taking into account that during the kneading process, as the airbag 16 continuously rotates in a circular motion, some tea leaves remain on the inner wall of the kneading barrel 13. Therefore, the present device solves this problem by providing a pushing assembly: an annular electric slide rail 2 is installed on the outer wall of the kneading barrel 13, a sliding member 21 is slidably connected to the electric slide rail 2, a fourth rack 22 is fixedly connected to the sliding member 21, three third gears 23 distributed in the circumferential direction are rotatably connected to the side wall of the kneading barrel 13 through ears, the fourth rack 22 is meshed with the third gear 23, and the kneading barrel 1 Three push plates 26 are circumferentially slidably connected along the upper edge, one end of each of the push plates 26 is built into and fits against the inner bottom wall of the kneading barrel 13, the other end of each of the push plates 26 penetrates the kneading barrel 13 and extends to the outside, one end of each of the push plates 26 extending to the outside is fixedly connected with a fifth rack 24, that is, the fifth rack 24 is placed on the outer wall of the kneading barrel 13, the fifth rack 24 is meshed with the third gear 23, a fourth spring 25 is compressed between the end of each of the push plates 26 extending to the outside through the kneading barrel 13 and the outer wall of the kneading barrel 13, so as to realize the reset of the push plate 26 by the fourth spring 25.

[0045] Before rolling, the three push plates 26 are attached to the inner wall of the rolling barrel 13 and form a complete ring. The fourth spring 25 is in a relaxed state. By starting the electric slide rail 2 to drive the sliding member 21 to rotate, the fourth rack 22 is controlled to rotate. The fourth rack 22 rotates and meshes with the third gear 23. The third gear 23 rotates and then meshes with the fifth rack 24, causing the fifth rack 24 to move inward. The push plates 26 are controlled to slide inwardly, and the fourth spring 25 deforms. As the sliding member 21 continues to rotate, the fourth rack 22 alternately meshes with the three third gears 23, and then the third gear 23 meshes with the fifth rack 24. The three fifth racks 24 alternately move, and the three push plates 26 alternately slide inwardly. Through the alternating sliding actions of the three push plates 26, the tea leaves remaining on the inner wall of the rolling barrel 13 are pushed to the central through-port of the rolling barrel 13 and then fall onto the material receiving tray 101, improving the utilization rate of the tea leaves.

[0046] During the above pushing process, as the sliding member 21 rotates, the push plates 26 are alternately pushed inward and then reset under the action of the fourth spring 25.

[0047] The rolled tea leaves are piled up on the rolling barrel 13. Since the bottom of the rolling barrel 13 is in contact with the material receiving tray 101, the tea leaves are piled up on the material receiving tray 101. To facilitate the collection of the tea leaves, a sealing plate that can be freely opened and closed is installed at the center of the axis of the material receiving tray 101. A funnel 32 for collecting tea leaves is fixedly connected to the bottom of the material receiving tray 101. When the sealing plate is opened, the tea leaves fall into the funnel 32. The bottom of the funnel 32 is not sealed, aiming to set a collection box at the bottom of the funnel 32 to collect the rolled tea leaves.

[0048] During the rolling process, some tea leaves will leak out from the bottom of the rolling barrel 13 and scatter along the wall of the material receiving tray 101. To facilitate the tea leaves along the wall of the material receiving tray 101 to fall into the funnel 32, a plurality of discharge slots 1011 are opened along the wall of the material receiving tray 101. Considering that the rolled tea leaves produce pectin due to cell breakage, resulting in some tea leaves adhering to the rolling barrel 13, this device solves this problem through a blowing component. An air guide pipe 3 is installed on the outer wall of the rolling barrel 13. The air guide pipe 3 is connected to the air delivery pipe 161 through a pipeline. A plurality of air nozzles 31 are connected through the air guide pipe 3. The air nozzles 31 are all aligned with the inner wall of the rolling barrel 13, aiming to transmit the air flow of the air delivery pipe 161 to the air nozzles 31 through the air guide pipe 3, so that the air nozzles 31 blow up the tea leaves adhering to the rolling barrel 13.

[0049] As the air valve 162 is opened, the gas in the air delivery pipe 161 is transmitted to the air nozzles 31 through the air guide pipe 3. Through the blowing action of the air nozzles 31, the tea leaves adhering to the rolling barrel 13 are blown up and fall into the funnel 32 from the discharge slots 1011, which is conducive to the collection of the tea leaves scattered on the material receiving tray 101.

[0050] A tea leaf processing device and processing method for making Purple Concubine Tea are as follows:

[0051] Step 1: Put the pre-treated Purple Concubine Tea into the rolling barrel 13, and turn on the switches of the motor 11 and the pressing cover 14.

[0052] Step 2: Drive the airbag 16 to press down and rotate through the pressing cover 14, so that the airbag 16 rolls the Purple Concubine Tea.

[0053] Step 3: The pressing cover 14 drives the support column 15 to move, so that the first rack 18 meshes with the first gear 19. The meshing of each tooth 1171 with the second gear 120 causes the second gear 120 to rotate repeatedly, thereby realizing the alternating opening and closing of the air valve 162, and enabling the airbag 16 to be inflated and expanded continuously according to the reduction of the volume of the tea leaves. Under the action of the first spring 17, the airbag 16 produces a uniform squeezing force on the Purple Concubine Tea.

[0054] Step 4: By starting the electric slide rail 2, drive the sliding member 21 and the fourth rack 22 to rotate. The fourth rack 22 meshes with the third gear 23, and the third gear 23 meshes with the fifth rack 24, driving the fifth rack 24 to move inwards. The push plates 26 are controlled to slide inwards uniformly, pushing the Purple Concubine Tea to the central through-port of the rolling barrel 13 and falling onto the material receiving tray 101.

[0055] Step 5: The air valve 162 is opened, and the air guide pipe 3 is connected to the air delivery pipe 161 through a pipeline, so that the air nozzle 31 blows air to blow up the Purple Concubine Tea on the rolling barrel 13 to prevent it from sticking to the rolling barrel 13.

[0056] Step 6: Open the sealing plate on the material receiving tray 101, so that the Purple Concubine Tea falls into the funnel 32 from the sealing plate and the discharge chute 1011 for easy collection.

[0057] The above are only the preferred embodiments of the present invention and are not used to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
