Description

Technical Field

[0001] The present invention relates to the technical field of tea fermentation, and specifically to a tea fermentation and fragrance-enhancing device and method thereof. Background Art

[0002] Tea is a finished product obtained by processing the tender leaves and buds of tea trees through processes such as picking, processing, and fermentation, and is widely used for brewing and drinking. The quality and flavor of tea largely depend on the control of the fermentation process. Fermentation is a key step in tea production, especially in the production of semi-fermented or fully fermented teas such as black tea and oolong tea. Through fermentation, the chemical components in tea change, thereby producing unique aromas and tastes.

[0003] Currently, when fermenting tea, after reaching a certain temperature, the tea needs to be continuously turned over. However, existing tea fermentation machines often do not have the function of turning over the tea. Therefore, it is still necessary for workers to manually turn over the tea. Opening the tea fermentation machine will destroy the temperature and humidity balance inside the fermentation machine, thereby reducing the fermentation quality of the tea.

[0004] There is a Chinese patent with an application number of 202510005500.2, which discloses a tea fermentation machine including a fermentation cylinder, and also includes: two doors respectively installed on the front of the fermentation cylinder; a plurality of legs fixedly connected to the bottom of the fermentation cylinder in an equal circumference.

The tea fermentation machine includes a box body, and a card slot is provided on the inner wall of the box body. A slide plate is slidably connected inside the card slot. A tray is provided on one side surface of the slide plate, and ventilation holes are provided at the bottom of the tray.

[0006] When fermenting tea according to the technical solutions in the above-mentioned multiple patent documents, the tea during the fermentation process is turned over by configuring mechanical structures. Inevitably, the mechanical structures will cause damage to the tea when turning it over, affecting its appearance. Moreover, when the existing equipment ferments tea, due to the layered placement of the tea, there are differences in ventilation between the tea at the bottom layer and the tea at the top layer, which easily causes different effects for the same batch of tea, affecting the product qualification rate. Summary of the Invention

A mounting seat is slidably connected to the peripheral wall of the cam. The front end of the traction rod is fixedly connected to the mounting seat.

[0027] Technical solution of the second aspect: A method for using a tea fermentation and fragrance-enhancing device, the method includes the following steps:

[0028] Step 1: Preparation work. Open the cabinet door of the equipment main body, start the electric push rod through the controller main body, so that the moving plate drives the placing component to move the whole to the outside of the equipment main body. Then, start the electric telescopic rod group in each bearing mechanism through the controller main body, so that the corresponding air-permeable disc moves up to the maximum distance. Next, place the mesh trays loaded with tea leaves on the bearing components in the corresponding bearing mechanisms respectively. After all the mesh trays are neatly placed, start the electric telescopic rod group in each bearing mechanism through the controller main body to drive the corresponding air-permeable disc to fall. The air-permeable disc covers the corresponding mesh tray from the top. Finally, start the electric push rod to run in reverse through the controller main body, drive the moving plate and the placing components arranged thereon to retract into the equipment main body, and then close the cabinet door of the equipment main body;

[0029] Step 2: Tea fermentation treatment. After the equipment main body finishes loading the tea leaves, start and run through the controller main body, and then carry out fermentation treatment on the tea leaves;

[0030] Step 3: Auxiliary fermentation:

[0031] Differential rotation. Start the motor in the driving mechanism through the controller main body. The motor drives a plurality of driving gears to rotate through the rotating shaft. Each driving gear meshes with the driven gear of the transmission component in the corresponding bearing mechanism respectively, so that the corresponding telescopic rod rotates. The telescopic rod drives the transmission gear to move. Each transmission gear meshes and drives with the corresponding external tooth ring respectively, so that the moving ring rotates, thereby driving the corresponding mesh tray to rotate. Since the number of teeth on each driving gear is different, the speed of the bearing components in each layer of bearing mechanism driving the corresponding mesh tray to rotate is different, so as to realize the relatively average ventilation requirements of the tea leaves in each mesh tray;

[0032] Blowing air. Start the fan main body in the air blowing mechanism through the controller main body. The fan main body blows air from the bottom up to the mesh trays placed in the bearing mechanisms of different layers through the main pipe and each branch pipe;

[0033] Step 4: Tea leaf turning. When the driving mechanism drives the bearing components in each bearing mechanism to rotate, it drives the wire mesh tray to move, and simultaneously drives the cam in the vibration component to rotate. During the rotation of the cam, the L-shaped plate makes a reciprocating motion in the front and back states through the traction rod, and then the single-sided wedge block moves synchronously. When the single-sided wedge block makes a reciprocating motion, it makes rolling contact with the ball of the contact rod, so as to realize the lifting of the U-shaped plate loaded on the contact rod under the cooperation of the resetting member. The U-shaped plates in each bearing mechanism are spliced by a support plate group. Therefore, each U-shaped plate makes a lifting motion under the cooperation of the corresponding resetting member. When each U-shaped plate moves, it synchronously drives the corresponding bearing component to make a lifting motion. The lifting of the bearing component causes the corresponding wire mesh tray arranged thereon to make a lifting motion, so as to realize the jolting of the tea leaves loaded in the wire mesh tray. The tea leaves are efficiently turned over along with the air flow blown out by the branch pipe under the condition of rotary jolting;

[0034] Step 5: Automatic collection of tea powder. The tea powder in the wire mesh trays in each bearing mechanism will directly fall into the corresponding collection tank after falling. When each U-shaped plate makes a lifting motion, it synchronously drives the sleeve in the corresponding sorting component to make a lifting motion. When the sleeve makes a lifting motion, the slider on its inner wall moves in the arc-shaped closed groove on the corresponding rotating shaft, so as to drive the rotating shaft to make a rotating motion. When the rotating shaft rotates, it drives the arc-shaped scraping plate loaded thereon to rotate inside the collection tank, so as to scrape and clean the tea powder falling into the collection tank. Due to the arc-shaped design of the arc-shaped scraping plate, the tea powder in the collection tank finally enters the collection component through the discharge port along with its movement for collection;

[0035] Step 6: Tea leaf discharging. Close the equipment main body, the driving mechanism and the blowing mechanism through the controller main body, then open the cabinet door of the equipment main body, and start the electric push rod again, so that the moving plate drives the placing component to be pushed out of the equipment main body. Then, start the electric telescopic rod group in each bearing mechanism to open the corresponding air-permeable plate. After taking out each wire mesh tray, place the wire mesh trays newly loaded with tea leaves on the bearing components in each bearing mechanism, and pull out and clean and reset the storage box in the collection component. Finally, start the electric push rod to run in the reverse direction through the controller main body, so that the moving plate drives the placing component back into the interior of the equipment main body, close the cabinet door in the equipment main body, and repeat the cycle to realize the fermentation and fragrance enhancement treatment of the subsequent tea leaves.

[0036] Compared with the prior art, the beneficial effects of the present invention are:

[0037] 1. By arranging multiple bearing mechanisms on the placement rack in a hierarchical manner, and then under the cooperation of the driving mechanism and the corresponding transmission components, the corresponding mesh trays in each bearing mechanism can perform differential rotation activities, so as to achieve the required ventilation requirements for the tea leaves distributed in the upper and lower layers under the condition of differential motion, and ensure the qualified rate of tea leaf fermentation and aroma enhancement.

[0038] 2. During the rotation of the mesh tray, it can cooperate with the vibration component to jolt the tea leaves, and then under the action of the air blowing mechanism, the tea leaves in the mesh tray can be efficiently flipped, replacing the existing mechanical structure for flipping tea leaves, reducing the probability of tea leaf breakage, and improving its appearance.

[0039] 3. A sorting component is arranged below the mesh tray in each bearing mechanism, so as to collect the tea powder generated during the tea leaf fermentation process, prevent the tea powder from the upper mesh tray from falling onto the lower mesh tray, and thus avoid the need for sieving the tea leaves after fermentation, optimizing the tea leaf production process and improving production efficiency.

[0040] 4. When the sorting component sorts the tea powder, as the vibration component drives the U-shaped plate to rise and fall, the sleeve drives the rotating shaft to drive the arc-shaped scraper to perform circular motion, so as to sort the tea powder falling into the bearing tray, and under the action of rotation, push the tea powder into the collection component, facilitating the staff to handle the tea powder and reducing the cleaning burden of the staff.

[0041] 5. The placement part is located on the moving plate, and with the cooperation of the slide rail group and the electric push rod, the overall pushing of the placement part can be realized, which is convenient for disassembling and assembling the mesh tray in the placement part outside the equipment main body, further reducing the operation trouble of the staff and improving work efficiency.

[0073] A plurality of jacks are formed on the bottom shell wall of the network disk 11 along the circumferential direction, and the jacks correspond to the convex rods. The cooperation between the jacks on the network disk 11 and the convex rods on the moving ring 82 realizes the stable assembly of the network disk 11.

[0074] Please refer to Figure 6 - Figure 8 , in the embodiment of the present invention, the transmission component 14 includes a connection seat arranged on the outer shell wall of the outer circle of the collection groove 71.

A transmission gear 143 is arranged on the telescopic rod 141 below the circular ring 81, and the transmission gear 143 is in meshing transmission with the corresponding external gear ring 83.

[0075] Since the output end of the telescopic rod 141 is rotatably connected to the bottom shell wall of the corresponding circular ring 81 through a bearing, the transmission gear 143 arranged thereon is always in the same plane as the corresponding external gear ring 83, ensuring the meshing transmission effect between the transmission gear 143 and the corresponding external gear ring 83.

[0076] Please refer to Figure 2 - Figure 5 and Figure 11, in the embodiment of the present invention, the driving mechanism 15 includes a motor 151 disposed on the top shell wall of the moving plate 3.

The number of teeth on the plurality of driving gears 153 gradually decreases from bottom to top. Thus, when the motor 151 drives each driving gear 153 to rotate, the meshing transmission between each driving gear 153 and the driven gear 142 will cause the rotation speed of each telescopic rod 141 to decrease from bottom to top, thereby realizing the rotation speed reduction of the mesh trays 11 in the plurality of bearing mechanisms from bottom to top, ensuring the average ventilation of the tea leaves on each mesh tray 11.

[0077] Two reset members 16 are arranged in each bearing mechanism, respectively disposed on the front and rear distributed support columns 61. Each reset member 16 includes a positioning ring, a reset spring and a sliding seat.

[0078] Among them, the positioning ring is fixedly connected to the outer shell wall of the support column 61, and both the reset spring and the sliding seat are sleeved on the support column 61. Among them, the top end of the reset spring is arranged at the bottom of the sliding seat, the bottom end of the reset spring is fixedly connected to the positioning ring, and the sliding seat and the corresponding ear seat are fixedly connected by bolts. Through the reset effect of the reset spring, the sliding seat can drive the ear seat connected thereto to perform reset adjustment, thereby driving the corresponding bearing assembly 8 to perform a reset movement. And during the reset process of the reset spring, it is easy to cause a bumping effect on the bearing assembly 8.

[0079] Please refer to Figure 2 - Figure 6 and Figure 12 , in the embodiment of the present invention, the air blowing mechanism 17 includes a fan main body 171, a main pipe 172 and branch pipes 173. Among them, the fan main body 171 is disposed on the top shell wall of the moving plate 3, the main pipe 172 is installed at the output end of the fan main body 171, and the top end of the main pipe 172 penetrates through a plurality of supporting plates 74.

[0080] There are a plurality of branch pipes 173, which are longitudinally and linearly distributed on the peripheral wall of the main pipe 172, and the inner cavities of the branch pipes 173 and the main pipe 172 are mutually communicated. The plurality of branch pipes 173 correspond one-to-one with the plurality of bearing mechanisms. Among them, the branch pipes 173 are located above the sorting assembly 7 and are used for blowing air into the interior of the mesh trays 11. A plurality of air nozzles are linearly arranged horizontally on the top shell wall of the branch pipes 173. Thus, while the mesh trays 11 in the bearing mechanism rotate and move up and down, the air blowing of the air blowing mechanism 17 into the mesh trays 11 will further improve the turning effect of the tea leaves in the mesh trays 11.

[0081] Please refer to Figure 2 - Figure 5, in the embodiment of the present invention, the vibration assembly 18 includes a slide bar 181 disposed on the outer wall of the bottom of the bottommost collection tank 71. An L-shaped plate 182 is slidably connected to the slide bar 181, and a fixing plate 183 is installed at the bottom end of the L-shaped plate 182. A single-sided wedge 184 is provided on the top of the fixing plate 183, and a contact rod 185 is provided above the single-sided wedge 184.

[0082] The contact rod 185 includes a rod body fixedly connected to the outer wall of the bottom of the bottommost U-shaped plate 12. A ball is rotatably connected to the bottom end of the rod body, and the ball is in rolling contact with the inclined surface of the single-sided wedge 184. When the L-shaped plate 182 moves back and forth on the slide bar 181, the single-sided wedge 184 is driven to move synchronously through the fixing plate 183, and the single-sided wedge 184 is in rolling contact with the ball of the contact rod 185 during the movement, thereby realizing the lifting movement of the U-shaped plate 12 carrying the contact rod 185.

[0083] A traction rod 186 is fixedly connected to the front side wall of the L-shaped plate 182. A cam 187 is provided on the front side of the traction rod 186 and is located on the rotating shaft 152. A mounting seat is slidably connected to the peripheral wall of the cam 187, and the front end of the traction rod 186 is fixedly connected to the mounting seat.

[0084] An annular groove is formed on the peripheral wall of the cam 187, and the mounting seat is slidably connected to the annular groove. The cam 187 rotates with the movement of the driving mechanism 15, thereby driving the traction rod 186 to move, and thus realizing the synchronous rotation and lifting movement of the mesh tray 11 in the carrying mechanism.

[0085] A method for using a tea fermentation and fragrance-enhancing device proposed by the present invention includes the following steps:

[0086] Step 1: Preparation work. Stack the tea leaves about to enter the fermentation process on each mesh tray 11. Then, open the cabinet door of the equipment main body 1, and start the electric push rod 4 through the controller main body on the equipment main body 1, so that the moving plate 3 drives the placement component to move to the outside of the equipment main body 1 as a whole.

[0087] Then, start the electric telescopic rod group 9 in each carrying mechanism through the controller main body, so that the corresponding air-permeable disc 10 moves up to the maximum distance. Next, place each mesh tray 11 loaded with tea leaves on the carrying component 8 in the corresponding carrying mechanism respectively.

[0088] During the placement of the mesh tray 11, the jacks formed at the bottom thereof correspond to the respective convex rods distributed on the top of the moving ring 82 in the carrying component 8, so that after the mesh tray 11 is placed on the moving ring 82, the respective convex rods are inserted into the corresponding jacks respectively, realizing the calibrated placement of the mesh tray 11.

[0089] After each network disk 11 is neatly placed, the electric telescopic rod groups 9 in each bearing mechanism are started through the controller main body to drive the corresponding air-permeable disks 10 to fall. The air-permeable disks 10 cover the corresponding network disks 11 from the top.

[0090] Finally, the electric push rod 4 is started to run in the reverse direction through the controller main body, driving the moving plate 3 and the placement components arranged thereon to retract into the interior of the equipment main body 1, and then the cabinet door of the equipment main body 1 is closed.

[0091] Step 2: Tea fermentation treatment. After the equipment main body 1 finishes loading the tea, it is started to run through the controller main body, and then the tea is fermented.

[0092] Step 3: Auxiliary fermentation:

[0093] Differential rotation. The motor 151 in the driving mechanism 15 is started through the controller main body. The motor 151 drives a plurality of driving gears 153 to rotate synchronously through the rotating shaft 152. Each driving gear 153 meshes with the driven gear 142 of the transmission component 14 in the corresponding bearing mechanism respectively, so that the corresponding telescopic rod 141 rotates.

[0094] The telescopic rod 141 drives the transmission gear 143 to move, and each transmission gear 143 meshes and drives with the corresponding external tooth ring 83 respectively, so that the moving ring 82 rotates. Since the network disks 11 on each moving ring 82 are inserted and placed with the moving ring 82 through the convex rod and the jack at this time, when the moving ring 82 rotates, the corresponding network disks 11 are driven to rotate synchronously.

[0095] Since the number of teeth on each driving gear 153 is different, the speeds of the bearing components 8 in each layer of bearing mechanism driving the corresponding network disks 11 to rotate are different, so as to realize relatively average ventilation requirements for the tea in each network disk 11, and avoid large differences between the tea at the bottom layer and the tea at the top layer during the fermentation process of the tea.

[0096] Blowing air. The fan main body 171 in the air blowing mechanism 17 is started through the controller main body. The fan main body 171 blows air from the bottom up to the network disks 11 placed in the bearing mechanisms of different layers through the main pipe 172 and each branch pipe 173.

[0097] Step 4: Tea turning. When the driving mechanism 15 drives the bearing components 8 in each bearing mechanism to rotate, it drives the network disks 11 to move and synchronously drives the cam 187 in the vibration component 18 to rotate.

[0098] During the rotation of the cam 187, the L-shaped plate 182 reciprocates back and forth through the traction rod 186, thereby causing the single-sided wedge 184 to move synchronously. When the single-sided wedge 184 reciprocates, it makes rolling contact with the balls of the contact rod 185, thereby realizing the lifting of the U-shaped plate 12 loaded on the contact rod 185 in cooperation with the reset member 16.

[0099] The U-shaped plates 12 in each loading mechanism are spliced through the support plate group 13, and then the U-shaped plates 12 move up and down accordingly in cooperation with the corresponding reset members 16. When each U-shaped plate 12 moves, it synchronously drives the corresponding loading assembly 8 to move up and down. The up and down movement of the loading assembly 8 causes the corresponding mesh trays 11 arranged thereon to move up and down, thereby realizing the jolting of the tea leaves loaded in the mesh trays 11. Under the condition of rotary jolting, the tea leaves are further efficiently flipped in cooperation with the air flow blown out by the branch pipe 173.

[0100] Step Five: Automatic collection of tea dust. The tea dust in the mesh trays 11 of each loading mechanism will directly fall into the corresponding collection tank 71 after falling. When each U-shaped plate 12 moves up and down, it synchronously drives the sleeve 75 in the corresponding sorting assembly 7 to move up and down.

[0101] When the sleeve 75 moves up and down, the slider on its inner wall moves in the arc-shaped closed groove on the corresponding rotating shaft 72, thereby driving the rotating shaft 72 to rotate. When the rotating shaft 72 rotates, it drives the arc-shaped scraper 73 loaded thereon to rotate inside the collection tank 71. In this way, the tea dust falling into the collection tank 71 is scraped and cleaned. Due to the arc-shaped design of the arc-shaped scraper 73, the tea dust in the collection tank 71 finally enters the collection assembly 5 through the discharge port along with its movement for collection.

[0102] Step Six: Tea discharging. The controller main body turns off the equipment main body 1, the driving mechanism 15 and the blowing mechanism 17. Then the cabinet door of the equipment main body 1 is opened, and the electric push rod 4 is started again, so that the moving plate 3 drives the placing component to be pushed out of the equipment main body 1.

[0103] Next, the electric telescopic rod groups 9 in each loading mechanism are started, so that the corresponding breathable discs 10 are opened to facilitate the removal of each mesh tray 11. After each mesh tray 11 is removed, a new mesh tray 11 filled with tea leaves is placed on the loading assembly 8 in each loading mechanism, and the storage box 52 in the collection assembly 5 is pulled out for cleaning and resetting. Finally, the controller main body starts the electric push rod 4 to run in reverse, so that the moving plate 3 drives the placing component back into the interior of the equipment main body 1, and the cabinet door in the equipment main body 1 is closed.

[0104] This process is repeated in a cycle to realize the fermentation and aroma enhancement treatment of subsequent tea leaves.

[0105] The above are only the preferred specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, making equivalent substitutions or changes should be covered within the protection scope of the present invention.
