Description

Technical Field

[0001] This invention relates to a tea preparation apparatus, and more particularly to a tea fermentation apparatus. Background Technology

[0002] The tea fermentation process requires a specific temperature and humidity environment. After reaching a certain temperature, the tea leaves must be constantly turned to ensure even fermentation, allowing sufficient oxygen to enter the tea pile and cultivate a large number of microorganisms.

[0003] Conventional fermentation machines typically spread the tea leaves evenly in multiple compartments of the fermentation chamber, and then manually turn them over every so often. This method has the problems of low fermentation efficiency and the easy introduction of other microorganisms, which can affect the quality of the tea. Summary of the Invention

[0004] This invention addresses the problems existing in the tea fermentation process in the prior art by providing a tea fermentation device.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution:

[0006] A tea fermentation device includes a fermentation box that forms a closed fermentation chamber inside the fermentation box. A tea placement rack is provided inside the fermentation box. The tea placement rack includes a fixed frame fixed to the side wall of the fermentation box and a rotating frame set on the fixed frame. The rotating frame includes two turntables that are arranged opposite to each other and are rotatably connected to the fixed frame. A plurality of rotatable cylinders are provided between the two turntables. The axial direction of the cylinders is parallel to the axial direction of the turntables and the plurality of cylinders are evenly arranged around the turntables. The side wall of the cylinder is mesh and the inside of the cylinder forms a tea placement chamber.

[0007] Preferably, the fixing frame includes two fixing columns fixed on the left and right inner side walls of the fermentation tank respectively, and a motor mounting frame connected between the two fixing columns, with a turntable rotating motor fixed on the motor mounting frame;

[0008] The turntable includes a rotating ring rotatably connected to a fixed column. The rotating ring has a first annular external tooth, and the motor shaft of the turntable rotation motor has an input gear that meshes with the first annular external tooth. The rotating ring is also connected to multiple connecting rods extending radially along the rotating ring. The ends of the connecting rods away from the rotating ring are equipped with rotating cylinder mounting seats. The rotating cylinders are rotatably connected to the rotating cylinder mounting seats. The structure of the fixed frame enables the rotating cylinders at the ends of the connecting rods to rotate around the fixed column, achieving uniform changes in the spatial position of all rotating cylinders in the fermentation chamber.

[0009] As a preferred embodiment, the fixing frame also includes two toothed rings fixed on the left and right inner side walls of the fermentation tank. The toothed rings are coaxially arranged with the fixing column and have annular inner teeth.

[0010] Each rotating drum mounting base includes an inner rotating sleeve and an outer rotating sleeve fitted outside the inner rotating sleeve. The outer rotating sleeve has a second annular outer tooth fixed on its outside, which meshes with the annular inner tooth and is used to drive the outer rotating sleeve to rotate. The rotating motor can drive the second annular outer tooth on all rotating drum mounting bases to rotate synchronously on the annular inner tooth, thereby realizing the rotation of the drum and turning the tea in the tea placing cavity. This allows the tea inside the tea pile to fully contact oxygen and moisture, ensuring that the tea can be effectively fermented both inside and out.

[0011] Preferably, the end of the rotating cylinder is connected to the inner rotating sleeve. A clutch mechanism is provided between the inner rotating sleeve and the outer rotating sleeve to enable the inner rotating sleeve to rotate synchronously with the outer rotating sleeve. The clutch mechanism includes a sliding column disposed inside the inner rotating sleeve and coaxially disposed with the inner rotating sleeve. A push ring is sleeved on the sliding column. A snap-fit ​​component that can retract or extend from the inner rotating sleeve radially is connected to the push ring via a connecting rod. A snap-fit ​​groove that mates with the snap-fit ​​component is provided on the inner side wall of the outer rotating sleeve. A drive spring is also provided on the sliding column. The drive spring is used to drive the push ring to push the snap-fit ​​component into the snap-fit ​​groove via the connecting rod.

[0012] The clutch mechanism allows the drum to rotate synchronously as needed during fermentation, enabling the tea leaves to be turned over after a period of fermentation to ensure uniform fermentation.

[0013] Preferably, the slide column is also connected to a guide post arranged perpendicularly to the slide column, and the end of the snap-fit ​​component facing the inner rotating sleeve axis is provided with a sliding groove hole for the guide post to extend into and slide axially. The cooperation between the guide post and the sliding groove hole can ensure that the snap-fit ​​component can move accurately along the radial direction of the roller drive shaft, thereby ensuring that the snap-fit ​​component can accurately snap into or out of the snap-fit ​​groove.

[0014] Preferably, the clutch drive mechanism is also included. The clutch drive mechanism includes a drive cylinder disposed in the fixed column. The piston rod of the drive cylinder is coaxially disposed with the fixed column and the end of the piston rod is connected to a drive ring assembly. The clutch drive mechanism also includes a push ring assembly disposed outside the outer rotating sleeve. The push ring assembly includes a push block with one end outside the outer rotating sleeve and the other end capable of radially pushing the snap-fit ​​member away from the snap-fit ​​groove. When the drive ring assembly moves toward the push ring assembly, it can squeeze the push block to push the snap-fit ​​member away from the snap-fit ​​groove.

[0015] Preferably, the fixing frame further includes a first fixing ring coaxially connected to the fixing column, the piston rod of the driving cylinder is connected to the first fixing ring, the driving ring assembly includes a connecting ring rotatably connected to the outer wall of the first fixing ring and a driving ring with an inclined surface on its inner surface, the inclined surface forming a pushing surface for pushing the push block, and a connecting arm evenly arranged between the connecting ring and the driving ring.

[0016] Preferably, the push ring assembly also includes arc-shaped plates connected to both sides of the push block. Adjacent arc-shaped plates can separate from each other and engage with each other when the push block pushes the latching member out of the latching groove. The outer surface of the arc-shaped plates and the outer surface of the push block can together form an arc surface that mates with the inclined surface. The structure of the push ring assembly enables the driving and resetting of the clutch mechanism. The push block pushes the latching member away from the latching groove, realizing the separation of the inner and outer rotating sleeves. When the external pressure on the push block is released, the latching member will push the push block out under the action of the drive spring, and the latching member will re-engage in the latching groove to realize the connection between the inner and outer rotating sleeves.

[0017] Preferably, the motor mounting bracket includes a second fixing ring coaxially connected to a fixing column and a motor mounting plate with both ends fixed to the second fixing ring, and the turntable rotating motor is fixed on the motor mounting plate.

[0018] Preferably, the fermentation chamber is equipped with temperature and humidity sensors to detect the temperature and humidity within the sealed fermentation chamber. The side walls of the fermentation chamber also have air inlets and outlets. A spray system can also be installed inside the fermentation chamber to automatically control the temperature and humidity, and to circulate oxygen through the air inlets and outlets. This allows fermentation to be completed without opening the fermentation chamber, preventing other microorganisms from entering and affecting the fermentation quality.

[0019] This invention, by adopting the above technical solutions, has significant technical effects:

[0020] This invention provides a tea-placing rack within the fermentation chamber that can rotate the tea leaves. This rack not only ensures uniform positional changes in all tea-placing chambers within the fermentation chamber but also allows the tea-placing chambers to rotate and rotate. Consequently, it not only ensures uniform distribution of tea leaves within a single chamber during fermentation but also uniform spatial position of all tea-placing chambers within the fermentation chamber, thus guaranteeing uniform tea fermentation.

[0029] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments.

[0030] Example 1

[0031] A tea fermentation device, such as Figures 1-8 As shown, the fermentation box 1 includes a closed fermentation chamber inside. The fermentation box 1 is equipped with a tea placing rack 2. The tea placing rack 2 includes a fixed frame 21 fixed to the side wall of the fermentation box 1 and a rotating frame 22 set on the fixed frame 21. The rotating frame 22 includes two turntables 201 that are arranged opposite to each other and are rotatably connected to the fixed frame 21. A plurality of rotating cylinders 23 are arranged between the two turntables 201. The axial direction of the rotating cylinders 23 is parallel to the axial direction of the turntables 201 and the plurality of rotating cylinders 23 are evenly arranged around the turntables 201. The side wall of the rotating cylinders 23 is mesh and the interior of the rotating cylinders 23 forms a tea placing chamber 202.

[0032] During the tea fermentation process, the tea leaves are distributed into multiple tea placement chambers 202 by the tea placement rack 2. Compared with placing all the tea leaves into one placement chamber, this makes the aerobic fermentation of the tea leaves more uniform.

[0033] During the fermentation process, all the tea-containing chambers 202 move evenly within the fermentation chamber, thereby ensuring the uniform distribution of tea leaves within the fermentation chamber space. This avoids uneven tea fermentation caused by differences in temperature and humidity at different locations within the fermentation chamber. Additionally, the rotating drum 23 can also generate a small-frequency and small-amplitude agitation of the tea leaves inside during its movement, further improving the uniformity of tea fermentation.

[0034] In addition, the rotating drum 23 itself can rotate, thereby enabling the tea leaves to be continuously turned over during the fermentation process, so that oxygen and moisture can be fully combined with the tea leaves inside the tea pile, ensuring that the tea leaves can be effectively fermented both inside and out.

[0035] In this embodiment, the fixing frame 21 includes two fixing columns 203 respectively fixed on the left and right inner side walls of the fermentation tank 1 and a motor mounting frame 204 connected between the two fixing columns 203. A turntable rotating motor 205 is fixed on the motor mounting frame 204. The motor mounting frame 204 includes a second fixing ring 217 coaxially connected to the fixing column 203 and a motor mounting plate 218 with both ends fixed on the second fixing ring 217. The turntable rotating motor 205 is fixed on the motor mounting plate 218.

[0036] The turntable 201 includes a rotating ring 206 rotatably connected to the fixed column 203. The rotating ring 206 is provided with a first annular external tooth 207. The motor shaft of the turntable rotary motor 205 is provided with an input gear 208 that meshes with the first annular external tooth 207. The rotating ring 206 is also connected to multiple connecting rods 209 extending radially along the rotating ring 206. The ends of the connecting rods 209 away from the rotating ring 206 are equipped with a rotating drum mounting seat 210. The rotating drum 23 is rotatably connected to the rotating drum mounting seat 210.

[0037] During the start-up process of the rotary motor 205, the input gear 208 drives the first annular external gear 207 to rotate, thereby realizing the rotation of the rotating ring 206 on the fixed column 203. After the rotating ring 206 rotates, it drives all the connecting rods 209 to rotate axially around the fixed column 203, thereby realizing the rotation of the rotating cylinder 23 at the end of the connecting rod 209 around the fixed column 203, and realizing the uniform change of the spatial position of all the rotating cylinders 23 in the fermentation chamber.

[0038] The fixing frame 21 also includes two toothed rings 211 fixed on the left and right inner side walls of the fermentation tank 1. The toothed rings 211 are coaxially arranged with the fixing column 203 and are provided with annular inner teeth 212.

[0039] Each rotary drum mounting base 210 includes an inner rotating sleeve 213 and an outer rotating sleeve 214 sleeved outside the inner rotating sleeve 213. A second annular outer tooth 215 is fixed outside the outer rotating sleeve 214, which meshes with the annular inner tooth 212 and is used to drive the outer rotating sleeve 214 to rotate. The turntable rotary motor 205 can drive the second annular outer tooth 215 on all rotary drum mounting bases 210 to rotate synchronously on the annular inner tooth 212.

[0040] During the rotation of the rotating ring 206, the second annular external tooth 215 moves on the annular internal tooth 212, which in turn drives the second annular external tooth 215 to rotate. The rotation of the second annular external tooth 215 can realize the rotation of the rotating drum mounting base 210, and then realize the rotation of the rotating drum 23, thereby turning over the tea in the tea placing cavity 202, so that the tea inside the tea pile can fully contact oxygen and moisture, so as to ensure that the tea can be effectively fermented both inside and out.

[0041] In this embodiment, the end of the rotating cylinder 23 is connected to the inner rotating sleeve 213, and a clutch mechanism 4 is provided between the inner rotating sleeve 213 and the outer rotating sleeve 214 to realize the inner rotating sleeve 213 rotating synchronously with the outer rotating sleeve 214.

[0042] The clutch mechanism 4 enables multiple rotating drums 23 to rotate around the fixed column 203 in a circumferential manner while also rotating synchronously on their own axis. It also allows the rotating drums 23 to be selected to rotate only around the fixed column 203 in a circumferential manner without rotating on their own axis, thus satisfying the requirement that the tea leaves do not need to be excessively turned during the fermentation process.

[0043] The clutch mechanism 4 includes a slide column 401 disposed inside the inner rotating sleeve 213 and coaxially disposed with the inner rotating sleeve 213. A push ring 402 is sleeved on the slide column 401. A snap-fit ​​member 404 that can retract or extend radially along the inner rotating sleeve 213 is connected to the push ring 402 via a connecting rod 403. A snap-fit ​​groove 405 that cooperates with the snap-fit ​​member 404 is provided on the inner side wall of the outer rotating sleeve 214. A drive spring 406 is also provided on the slide column 401. The drive spring 406 is used to drive the push ring 402 to push the snap-fit ​​member 404 into the snap-fit ​​groove 405 via the connecting rod 403.

[0044] The slide column 401 is also connected to a guide column 407 arranged perpendicularly to the slide column 401. The end of the snap-fit ​​404 facing the axis of the inner rotating sleeve 213 is provided with a sliding groove hole 408 for the guide column 407 to extend into and slide axially.

[0045] During the fermentation process, at the initial fermentation stage, the turntable rotary motor 205 drives all connecting rods 209 to rotate axially around the fixed column 203, thereby enabling the rotating cylinders 23 at the ends of the connecting rods 209 to rotate around the fixed column 203, achieving uniform fermentation of all rotating cylinders 23 in the fermentation chamber. At this time, the clutch mechanism 4 is in the disengaged state, the outer rotating sleeve 214 rotates, the inner rotating sleeve 213 does not rotate, and consequently the rotating cylinders 23 do not rotate.

[0046] As fermentation progresses, the tea leaves inside the tea-placement chamber 202 need to be turned over so that they can fully come into contact with oxygen and moisture. At this time, the clutch structure is in a closed state. The outer rotating sleeve 214 will drive the inner rotating sleeve 213 to rotate during its rotation, which in turn drives the rotating drum 23 to rotate, thus turning the tea leaves inside.

[0047] During the post-fermentation stage, the clutch mechanism 4 can be adjusted to rotate and turn the tea leaves according to actual needs, so as to ensure that the desired fermentation effect is achieved in the end.

[0048] This embodiment also includes a clutch drive mechanism 5, which includes a drive cylinder 501 disposed in the fixed column 203. The piston rod of the drive cylinder 501 is coaxially disposed with the fixed column 203 and the end of the piston rod is connected to a drive ring assembly 51. The clutch drive mechanism 5 also includes a push ring assembly 52 disposed outside the outer rotating sleeve 214. The push ring assembly 52 includes a push block 507 with one end outside the outer rotating sleeve 214 and the other end capable of radially pushing the snap fastener 404 out of the snap fastener groove 405. When the drive ring assembly 51 moves toward the push ring assembly 52, it can squeeze the push block 507 to push the snap fastener 404 out of the snap fastener groove 405.

[0049] The fixing frame 21 also includes a first fixing ring 216 coaxially connected to the fixing column 203. The piston rod of the driving cylinder 501 is connected to the first fixing ring 216. The driving ring assembly 51 includes a connecting ring 502 rotatably connected to the outer wall of the first fixing ring 216 and a driving ring 503 with an inclined surface 504 on its inner surface. The inclined surface 504 forms a pushing surface for pushing the push block 507. Connecting arms 505 are evenly arranged between the connecting ring 502 and the driving ring 503.

[0050] In addition, the connecting ring 502 and the first fixed ring 216 are engaged by an annular groove, which allows them to rotate relative to each other in the circumferential direction but not in the axial direction. Therefore, when the drive cylinder 501 drives the first fixed ring 216 to move axially, the first fixed ring 216 will drive the connecting ring 502 to move synchronously, thereby enabling the drive ring 503, which is connected to the connecting ring 502 through the connecting arm 505, to move synchronously. This allows the inclined surface 504 on the drive ring 503 to press the push block 507, causing the push block 507 to move toward the inside of the outer rotating sleeve 214, and then radially push the engaging member 404 to disengage from the engaging groove 405.

[0051] The push ring assembly 52 also includes arc-shaped plates 506 connected to both sides of the push block 507. Adjacent arc-shaped plates 506 can separate from each other and engage with each other when the push block 507 pushes the snap-fit ​​member 404 out of the snap-fit ​​groove 405. The outer surface of the arc-shaped plate 506 and the outer surface of the push block 507 can jointly form an arc surface that cooperates with the inclined surface 504. The arc-shaped plate 506, which forms the same arc surface as the outer surface of the push block 507, can make the inclined surface 504 on the drive ring 503 have a larger contact surface when it acts on the push block 507. As the outer rotating cylinder 23 rotates, it can push the push block 507 better.

[0052] In this embodiment, adjacent arc-shaped plates 506 are hinged to each other. Specifically, they can be connected by springs with spherical parts at both ends. Specifically, a spring hole with a diameter smaller than that of the spherical part can be provided at the end of one arc-shaped plate 506, so that the spring is placed in the spring hole and the spherical part extends out of the spring hole. A circular groove for engaging the spherical part is provided on the other arc-shaped plate 506. The spherical part may be engaged in the circular groove and can be disengaged from the circular groove under the action of external force, thereby realizing the mutual separation and engagement between adjacent arc-shaped plates 506.

[0053] In addition, in order to ensure that the separated arc plate 506 can be accurately engaged again, the push block 507 is designed as a rectangular block, and the outer rotating sleeve 214 is provided with a rectangular hole that matches the rectangular block. This ensures that the push block 507 and the arc plate 506 on it can only move radially along the outer rotating sleeve 214, thereby ensuring that the separated arc plate 506 can be engaged again.

[0054] In this embodiment, the fermentation chamber 1 is equipped with sensors 101 for detecting the temperature and humidity inside the sealed fermentation chamber. Sensor 101 includes a temperature sensor and a humidity sensor. An air inlet 102 and an air outlet 103 are also provided on the side wall of the fermentation chamber 1. A spray system can also be installed inside the fermentation chamber to automatically control the temperature and humidity. Oxygen circulation is achieved through the air inlet 102 and the air outlet 103, allowing fermentation to be completed without opening the fermentation chamber, thus preventing other microorganisms from entering the fermentation chamber and affecting the fermentation quality.

[0055] It is readily understood that those skilled in the art can combine, split, or reorganize the embodiments provided in this application to obtain other embodiments, none of which exceed the protection scope of this application.

[0056] In summary, the above description is only a preferred embodiment of the present invention. All equivalent changes and modifications made within the scope of the claims of the present invention should be covered by the present invention.
