Description

Technical Field

[0001] This invention relates to the field of fermentation equipment technology, specifically to a fermentation device for tea processing. Background Technology

[0002] Fermentation of tea refers to the enzymatic reaction of substances inside the tea leaves, also known as biological oxidation. It is a series of oxidation processes in which oxidases in the cell walls of tea leaves promote the oxidation of catechins after the cell walls are broken. After fermentation, the color, aroma, and taste of tea leaves will change, thus forming the quality and style of the tea. Common teas such as black tea and Pu-erh tea require fermentation during the production process.

[0003] Currently, the commonly used tea fermentation methods are mainly divided into large-pile fermentation and small-pile off-ground fermentation. Small-pile off-ground fermentation can effectively suppress the pile flavor produced by large-pile fermentation, and the fermentation process heats up quickly and is highly efficient. However, small-pile off-ground fermentation is prone to uneven fermentation, so the frequency of turning the pile is higher than that of large-pile fermentation. Moreover, the containers for small-pile fermentation still often require manual turning, which is labor-intensive.

[0004] A search revealed that patent CN218043599U discloses a tea fermentation machine. In use, tea leaves are first added to the fermentation cylinder through the feeding port, and then the tea fermentation operation is carried out in the fermentation cylinder. During the fermentation process, the motor is started as needed. After the motor is started, it can drive the rotating shaft connected to it to rotate together. Since the rotating shaft is equipped with a stirring component, the rotating shaft can carry the stirring component to stir the tea leaves in the fermentation cylinder, so that the tea leaves can ferment more evenly and fully, thereby improving the quality of the tea.

[0005] The above-mentioned device is used by pouring tea leaves into a fermentation tank for fermentation and then turning them over by stirring blades. The stirring blades are driven by multiple sets of conical teeth. The lubricating oil on the conical teeth will affect the fermentation of the tea leaves. If the lubricating oil is not used, the wear of the conical teeth will increase, thereby affecting the turning of the stirring blades and making the turning effect of the device poor. Therefore, a fermentation device for tea processing is proposed to solve the above-mentioned problems. Summary of the Invention

[0037] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0038] Please see Figure 1-11 One embodiment of the present invention is: a fermentation device for tea processing, including a fermentation box 1 and a box door 2, the box door 2 being hinged to the front of the fermentation box 1, and a flipping mechanism 3 being provided inside the fermentation box 1;

[0039] The turning mechanism 3 includes a base plate 31, two connecting plates 32, four round rods 33, four springs 34, two round plates 37, four uprights 38, and three placement trays 312. The base plate 31 is located inside the fermentation chamber 1. The four uprights 38 are connected to the top four corners of the base plate 31. The two round plates 37 are located at the bottom of the base plate 31. The two connecting plates 32 are respectively connected to the front and rear sides of the base plate 31. The four round rods 33 are slidably connected to the two connecting plates 32, and the bottom of the four round rods 33 is connected to the bottom of the inner wall of the fermentation chamber 1. The four springs 34 are respectively... The outer walls of the four round rods 33 are fitted with springs 34, and the two ends of each spring 34 are connected to the bottom of the inner wall of the fermentation tank 1 and the bottom of the corresponding connecting plate 32, respectively. Six connecting plates 39 are provided on the left and right sides of the three placement trays 312. Each connecting plate 39, near the corresponding placement tray 312, is rotatably connected to a rotating rod 310 via a bearing. The outer walls of two horizontally adjacent rotating rods 310 are connected to the two ends of a support plate 311. Gears 314 are fitted on the outer walls of the six rotating rods 310, and the six gears 314 mesh with two racks 316. Each gear... Each of the three placement trays 316 has two fixed rods 315 connected to its back. Each of the three placement trays 312 has a mesh cover 313 on its top. A motor 36 is installed on the left side of the fermentation box 1. The right end of the motor 36's output shaft extends through the left side of the fermentation box 1 into its interior, and is rotatably connected to the right side of the inner wall of the fermentation box 1 via a bearing. The motor 36's output shaft passes through the non-center of two circular plates 37, driving the two circular plates 37 to rotate eccentrically. Two limiting plates 35 are connected to the top of the four circular rods 33, and the two limiting plates 35 are located on the front and rear sides of the base plate 31, respectively. The tray 311, the placement plate 312, and the mesh cover 313 are arranged in three groups with six rotating rods 310 and gears 314, and each group is arranged in a vertical linear equidistant array. Each mesh cover 313 is connected to a handle at the top. Each tray 311 is connected to an L-shaped plate 317 on the front and back sides of its outer wall. Two L-shaped plates 317, together with a single tray 311, support a single placement tray 312. Each placement tray 312 has a threaded groove on its front side, and the threaded groove is threaded with a bolt 318. The bolt 318 is threaded to the L-shaped plate 317 on the front side of each placement tray 312.

[0040] Working principle: By placing the fermentation box 1 in a suitable position and connecting it to an external power source, tea leaves are poured into the placement tray 312, spread out, and then the mesh cover 313 is closed. During fermentation, the motor 36 is started, driving the circular plate 37 on its output shaft to rotate eccentrically. The circular plate 37 continuously presses against the bottom plate 31, causing the bottom plate 31 to vibrate up and down continuously under the cooperation of the connecting plate 32, the circular rod 33, and the spring 34. This causes the tea leaves placed in the placement tray 312 to shake up and down, thus dispersing the tea leaves by impacting the inner wall of the placement tray 312. The vibration of the bottom plate 31 drives... The connecting plate 39 on the upright 38 vibrates up and down, which drives the gear 314 on the rotating rod 310 to move up and down. Under the meshing of the rack 316, the gear 314 is driven to rotate, thereby driving the rotating rod 310 to rotate. This causes the rotating rod 310 to drive the tray 311 to rotate in both directions. The tray 311 drives the placement tray 312 to swing back and forth. The swinging placement tray 312 simulates the effect of manually using a winnowing basket to mix the tea leaves, further improving the tea leaf turning effect, increasing the contact area with air, and avoiding local accumulation that would affect fermentation.

[0041] Furthermore, all four uprights 38 are connected to the top of the base plate 31 via triangular plates to improve the connection strength of each upright 38. The bottom of the placement tray 312 has holes so that the fermentation liquid can be sprayed into the placement tray 312 after the mesh cover 313 is closed. By setting an L-shaped plate 317, it can work with the support plate 311 to provide cross-shaped support for the bottom of the placement tray 312. The bottom of the inner wall of the support plate 311 is provided with a circular positioning plate. When the placement tray 312 is placed in the support plate 311, the circular positioning plate is embedded in the bottom circular groove of the placement tray 312, which facilitates the positioning of the placement tray 312. After placement, the threaded groove on the placement tray 312 is aligned with the bolt 318. The placement tray 312 can be locked by screwing the bolt 318 into the threaded groove, thereby improving the stability of tea fermentation.

[0042] Please see Figure 1-11Based on the above embodiments, in another embodiment of the present invention, the fermentation box 1 is provided with a toggle mechanism 4. The toggle mechanism 4 includes a crossbar 41, a round rod 43, and a lever 44. The round rod 43 is connected to the bottom of the crossbar 41, and the lever 44 is connected to the outer wall of the round rod 43. Each connecting plate 39 has a notch 1 at its top, and each notch 1 is connected to a trapezoidal block 42. Each placement tray 312 has four notches 2 at its top, and each placement tray 312 has two crossbars 41 at its top. Each crossbar 41 passes laterally through the two notches 2 at the top of the corresponding placement tray 312, and also passes through the notch 1 on the connecting plate 39. The number of round rods 43 at the bottom of each crossbar 41 is three, and the outer wall of each round rod 43 is connected to multiple levers 44. Each horizontal bar 41 has its outer wall in contact with the inclined surface of two trapezoidal blocks 42. The two horizontal bars 41 are grouped together, and each group of horizontal bars 41 has a sliding plate 45 connected to its left and right ends. Each sliding plate 45 has four connecting blocks 46 connected to one side of its outer wall. A round rod 47 is connected between two adjacent connecting blocks 46 on each sliding plate 45. Two springs 48 are fitted on the outer wall of each round rod 47, and the two ends of each spring 48 are connected to the outer wall of the corresponding connecting block 46 and the horizontal bar 41, respectively. The side of each sliding plate 45 away from the connecting block 46 is slidably connected to the inner wall of the fermentation tank 1 through a sliding groove opened in the inner wall of the fermentation tank 1. A spring 3 is set inside the sliding groove. Each horizontal bar 41 has two baffles 49 connected to its bottom, and the inner wall of the baffles 49 is in contact with the outer wall of the placement tray 312.

[0043] Working principle: When the motor 36 is started, the tea leaves in the placement tray 312 are turned over. The trapezoidal block 42 in the notch of the connecting plate 39 will move up and down as the connecting plate 39 vibrates. When the trapezoidal block 42 moves up, the inclined surface presses against the crossbar 41. After being pressed, the crossbar 41 moves horizontally in the longitudinal direction. The two springs 48 at the end of each crossbar 41 are compressed and stretched. When the trapezoidal block 42 moves down and does not press against the crossbar 41, the springs 48 drive the crossbar 41 to move in the opposite direction to reset. This process is repeated so that the crossbar 41 drives the lever 44 on its bottom round rod 43 to move back and forth repeatedly. The lever 44, in conjunction with the swinging placement tray 312, moves the tea leaves inside, further improving the tea leaf turning effect.

[0044] Furthermore, the second notch is designed to allow space for the movement of the crossbar 41, while the baffle 49 can cover the second notch to prevent the tea leaves in the placement tray 312 from splashing out from the second notch when they are turned over. The crossbar 41 is located at the bottom of the mesh cover 313. The placement tray 312 is placed first so that the crossbar 41 passes through the second notch, and then the mesh cover 313 is closed. The mesh cover 313 can prevent the tea leaves from running out. The sliding plate 45 is installed in conjunction with the slide groove, the slider and the spring three, so that the sliding plate 45 can slide up and down on the inner wall of the fermentation box 1. Moving the sliding plate 45 up causes the crossbar 41 to move up, so that the placement tray 312 can be picked up and put down. It also gives the crossbar 41 the ability to buffer upwards. The lever 44 and the round rod two 43 in the placement tray 312 do not collide with the inner wall when the placement tray 312 swings, so as to avoid damage.

[0045] Please see Figure 1-11Based on the above embodiments, in another embodiment of the present invention, a spraying mechanism 5 is provided on the top of the base plate 31.

Multiple nozzles 510 are connected to the bottom of the spray pipe 59. There are three connecting pipes 56 and spray pipes 59. Each placement plate 312 has one connecting pipe 56 and one spray pipe 59 above it. The bottom of each connecting pipe 56 is connected to an inner tube 57, and an outer tube 58 is inserted into the outside of the inner tube 57. A sealing sleeve 511 is fitted on the outer wall of each inner tube 57. The top of each outer tube 58 is rotatably installed inside the corresponding sealing sleeve 511 through a bearing 512. Each outer tube 58 is connected to the top middle section of the corresponding spray pipe 59, and a gear 513 is fitted on its outer wall. Gear 2 513 meshes with rack 2 514, and the rear end of rack 2 514 is connected to the back of the inner wall of fermentation tank 1. A transmission wheel is sleeved on the outer wall of the output shaft of motor 36. Rotary rod 2 516 is rotatably mounted on the left side of fermentation tank 1 via bearing 4, and rotary rod 2 516 passes through the left side of fermentation tank 1. A transmission wheel is also sleeved on the outer wall of rotary rod 2 516. A conveyor belt 515 is sleeved on the outer wall of the two transmission wheels. A stirring rod 522 is connected to the outer wall of rotary rod 2 516, and the stirring rod 522 is located inside water tank 51. A liquid inlet is provided at the top of water tank 51, and an observation port is provided on the front. A rectangular rod 518 is connected to the outer wall of the diversion pipe 55. A circular plate 2 517 is connected to the right end of rotary rod 2 516, and rotary rod 2 516... The right end of 516 is connected to the non-center position on the left side of the second circular plate 517, which is used to drive the second circular plate 517 to rotate eccentrically when rotating. The outer wall of the second circular plate 517 fits against the inner wall of the notch three at the front end of the rectangular rod 518. The outer wall of the diversion pipe 55 is connected to the fourth circular rod 520. The back of the inner wall of the fermentation tank 1 is connected to the circular sleeve 519, and the rear end of the fourth circular rod 520 is slidably connected to the inside of the circular sleeve 519. The inside of the circular sleeve 519 is equipped with the fourth spring 521. The sealing sleeve 511 can improve the sealing between the inner tube 57 and the outer tube 58. The bearing three 512 allows the outer tube 58 to rotate. The observation port on the front of the water tank 51 can be used to check the liquid content of the water tank 51 at any time so as to add liquid in time.

[0046] Working principle: Water tank 51 can store water or fermentation liquid according to the needs of tea fermentation. When pump body 52 is started, the liquid in water tank 51 is transported into diversion pipe 55 through connecting pipe 53 and hose 54. Diversion pipe 55 transports liquid to three connecting pipes 56, and then through inner pipe 57 and outer pipe 58 to spray pipe 59, so that the liquid required for tea fermentation is sprayed from nozzle 510 onto tea leaves in placement tray 312. When spraying liquid, motor 36 is started, causing placement tray 312 to swing. When motor 36 starts, drive wheel and conveyor belt 515 rotate in opposite directions. The second rod 516 drives the rotation, causing the circular plate 517 at its right end to rotate eccentrically. The circular plate 517 continuously presses against the rectangular rod 518, causing the diversion pipe 55 to vibrate back and forth horizontally under the cooperation of the circular rod 520, the circular sleeve 519 and the spring wire 521. When the diversion pipe 55 vibrates back and forth horizontally, it will drive the connecting pipe 56 to move back and forth, causing the gear 513 to drive the spray pipe 59 at the bottom of the outer insertion pipe 58 to rotate under the cooperation of the rack 514, thereby increasing the spraying range and ensuring that the tea leaves are sprayed evenly, thus allowing the tea leaves to ferment fully.

[0047] Furthermore, when the rotating rod 516 rotates, it will drive the stirring rod 522 on it to rotate. The stirring rod 522 stirs the liquid in the water tank 51, improving the liquid usage effect. When the diversion pipe 55 vibrates, under the transmission of the gear 513 and the rack 514, the spray pipe 59 can cover the entire placement plate 312 by rotating at a maximum angle of half a turn.
