Description

Technical Field

[0001] The invention relates to the technical field of wolfberry black tea raw material fermentation, in particular to a wolfberry black tea raw material fermentation device and a fermentation method thereof. Background Art

[0002] As people's demand for healthy drinks continues to increase, wolfberry black tea, as a tea with unique flavor and health benefits, has received widespread attention. In the production process of wolfberry black tea, the fermentation of black tea leaves is a key link, and its fermentation effect directly affects the quality and taste of wolfberry black tea.

[0003] The traditional method of fermenting black tea usually uses a fermentation cabinet. Although the temperature and humidity inside the cabinet are controllable, because the tea leaves need to be stacked for fermentation, the contact area between the tea leaves inside and the air is much lower than that of the tea leaves outside. As a result, the degree of fermentation inside and outside the black tea leaves is different. The fermentation speed and degree of the tea leaves inside are relatively poor, and there are problems such as difficult to control the fermentation process, low fermentation efficiency, and unstable fermentation effect.

[0004] In view of this, this application is hereby filed. Summary of the invention

[0007] Furthermore, an adjustment component is arranged below the wave plate, and the adjustment component includes a partition fixedly connected to the inner wall of the fermentation cabinet, a limit sleeve is arranged on the top surface of the partition, a limit block is slidably connected in the limit sleeve, the wave plate is made of elastic material, and the top of the limit block is in contact with the wave crest of the wave plate.

[0008] Furthermore, there are multiple limit sleeves distributed at intervals, and their positions correspond to the wave crest positions of the wave plate. An adjusting screw is radially rotatable in the partition, and the adjusting screw is threadedly connected to the limit block. A worm gear is provided at the bottom end of the adjusting screw. A worm gear is radially rotatably inserted on the back of the fermentation cabinet, and the worm gear is engaged with multiple worm gears at the same time.

[0009] Furthermore, the pushing assembly also includes a motor, which is fixedly mounted on the back of the fermentation cabinet. The output shaft of the motor is connected to a driving screw, and the driving screw is threadedly connected to the sleeve.

[0010] Furthermore, a connecting shaft is fixedly connected to the push rod, the bottom end of the connecting shaft contacts the wave plate, a sliding block is vertically slidably provided in the sliding sleeve, and the connecting shaft is fixedly connected to the sliding block.

[0011] Furthermore, there are two sliding sleeves, which are symmetrically arranged on both sides of the inner wall of the fermentation cabinet. At least one of the sliding sleeves is provided with a spring, and both ends of the spring are fixedly connected to the slider and the sliding sleeve respectively.

[0012] Furthermore, a mounting column is provided on the back of the fermentation cabinet, the motor is fixedly connected to the mounting column by bolts, and a harmonic reducer is provided between the motor and the driving screw.

[0013] Furthermore, the driving screw is a reciprocating threaded rod, and the push rod is cylindrical.

[0014] Furthermore, a top plate is provided at the top of the limit block, the top surface of the top plate contacts the wave plate, and the top surface of the top plate is in an arc shape.

[0015] Furthermore, a method for fermenting wolfberry black tea raw materials comprises the following steps: in the preparation stage, placing the wolfberry black tea to be fermented on a mesh; in the fermentation stage, the motor is started, and the drive screw is driven to rotate through the harmonic reducer, so that the sleeve slides back and forth on the inner wall of the fermentation cabinet, and the push rod in the sleeve moves with the sleeve, and slides back and forth and rises and falls along the top surface of the wave plate, and the push rod pushes the mesh when moving upward; according to actual needs, the wave amplitude of the wave plate can be adjusted by adjusting the component, and the worm on the back of the fermentation cabinet is rotated to drive multiple worm wheels that are simultaneously meshed with the worm to rotate, and the worm wheel drives the adjusting screw to rotate, thereby controlling the lifting and lowering of the limit block and adjusting the wave peak height of the wave plate.

[0017] In the present invention, the wave plate made of elastic material is matched with a limit block with adjustable height. The limit block is driven to rise and fall by rotating the adjusting screw, so as to adjust the height of the wave crest of the wave plate, thereby realizing the adjustment of the pushing amplitude of the push rod, preventing the thinner stacked tea leaves from splashing out due to excessive pushing amplitude, and preventing the thicker stacked tea leaves from being pushed due to too small pushing amplitude, thereby adapting to various production needs.

[0018] In the present invention, the design of the worm wheel and the worm enables the height of multiple limit blocks to be adjusted simultaneously by rotating the worm on the back of the fermentation cabinet when the pushing amplitude of the push rod needs to be adjusted, making the adjustment of the wave plate more convenient.

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0022] See also Figure 1-9 , the present invention provides a technical solution: A device for fermenting wolfberry black tea raw materials and a fermentation method thereof, comprising a fermentation cabinet 1 and a placement component 2, wherein the placement component 2 comprises a guide rail 201, a connection frame 202 and a mesh 203, wherein two guide rails 201 are symmetrically arranged on both sides of the inner wall of the fermentation cabinet 1, the connection frame 202 is in a square shape, and guide blocks 204 are arranged on both sides thereof, the connection frame 202 is slidably connected to the guide rail 201 through the guide blocks 204, the lower end of the guide block 204 is rotatably connected to a roller 205, the top end of the mesh 203 is fixedly connected to the fermentation cabinet 1, the top surface is provided with an opening, and is concave downwards for placing black tea leaves.

[0023] The mesh 203 is slidably connected to the guide rails 201 on both sides of the inner wall of the fermentation cabinet 1 through the connecting frame 202, so that the mesh 203 can be drawn out of the fermentation cabinet 1, which makes it more convenient to store and retrieve tea leaves.

[0024] The guide blocks 204 on both sides of the connecting frame 202 allow the connecting frame 202 to slide only along the length direction of the guide rail 201. The rollers 205 at the lower ends of the guide blocks 204 reduce the friction resistance between the connecting frame 202 and the guide rail 201 during the retraction and extension process, making it easier to pull out the connecting frame 202.

[0025] A sealed door 101 is hinged on the front of the fermentation cabinet 1, and an observation window 102 is provided on the sealed door 101. A control panel 5 is provided on the side of the fermentation cabinet 1. A fermenter 501 electrically connected to the control panel 5 is provided on the top of the inner part of the fermentation cabinet 1. The control panel 5 includes a liquid crystal panel, remote sensing and control buttons. A humidity and temperature sensor electrically connected to the liquid crystal panel is provided in the fermentation cabinet 1. The fermenter 501 includes a compressor and a humidifier for controlling the temperature at 25°C-30°C and the humidity at 90%.

[0026] The design of the sealed door 101 allows the interior of the fermentation cabinet 1 to form a closed cavity to ensure that the temperature and humidity inside the fermentation cabinet 1 are not lost. The design of the observation window 102 allows the supervisor to directly observe the fermentation status of the tea leaves in the mesh 203 outside the fermentation cabinet 1, making the fermentation process clearer.

[0027] The design of the fermenter 501 makes the humidity and temperature in the fermentation cabinet 1 controllable, which can accelerate the fermentation process and fermentation effect of the tea leaves in the mesh 203 to a certain extent.

[0028] The design of the control panel 5 enables the temperature and humidity inside the fermentation cabinet 1 to be displayed intuitively, making it convenient for the staff to control the fermenter 501.

[0029] It also includes a pushing component 3 for pushing the mesh 203; the pushing component 3 includes a push rod 301, which is located below the mesh 203; a sliding sleeve 302, which is connected to the inner wall of the fermentation cabinet 1 and can slide back and forth, and the push rod 301 can only slide vertically in the sliding sleeve 302; a wave plate 303, which is arranged on the inner side of the sliding sleeve 302, and has a wave-shaped top surface, which conflicts with the bottom end of the push rod 301.

[0030] A connecting shaft 307 is fixedly connected to the push rod 301, and the bottom end of the connecting shaft 307 contacts the wave plate 303. A slider 306 is vertically slidably provided in the sleeve 302. A connecting port 103 is provided in the fermentation cabinet 1, and the connecting shaft 307 passes through the connecting port 103 and is fixedly connected to the slider 306.

[0031] The connecting shaft 307 fixedly connects the push rod 301 and the slider 306. The design of the sliding sleeve 302 and the slider 306 allows the push rod 301 to slide only vertically. Since the bottom end of the push rod 301 contacts the top surface of the wave plate 303 due to gravity, when the sliding sleeve 302 slides back and forth, the push rod 301 will move up and down, pushing the tea leaves in the mesh 203 to turn over, thereby accelerating the fermentation efficiency and effect of the tea leaves therein.

[0032] The pushing assembly 3 also includes a motor 304 , which is fixedly mounted on the back of the fermentation cabinet 1 . The output shaft of the motor 304 is connected to a driving screw 305 , which is threadedly connected to the sleeve 302 .

[0033] By setting the motor 304, when flipping is required, the driving screw 305 can be driven to rotate by starting the motor 304, and the sliding sleeve 302 threadedly connected thereto can be driven to reciprocate, thereby achieving the above effect and effectively reducing labor costs.

[0034] The driving screw 305 is a reciprocating threaded rod. By setting the driving screw 305 as a reciprocating threaded rod, the motor 304 only needs to rotate in one direction to drive the push rod 301 to move back and forth in the fermentation cabinet 1, without the need for frequent switching of directions, which improves the service life of the motor 304 to a certain extent.

[0035] The push rod 301 is cylindrical. When the push rod 301 collides with the mesh 203, the contact area between the push rod 301 and the mesh 203 is larger, and the push rod 301 has no sharp edges, which can prevent the push rod 301 from scratching the mesh 203, thereby improving the service life of the mesh 203 to a certain extent.

[0036] A mounting column 104 is provided on the back of the fermentation cabinet 1 , and the motor 304 is fixedly connected to the mounting column 104 by bolts. A harmonic reducer 309 is provided between the motor 304 and the driving screw 305 .

[0037] The design of the harmonic reducer 309 can reduce the rotation speed of the motor 304, making the operation of the device more stable. The push rod 301 will not move too fast due to the excessive rotation speed of the motor 304, causing excessive impact force on the tea leaves in the mesh 203 and causing the tea leaves to fly out of the mesh 203.

[0038] There are two sliding sleeves 302, which are symmetrically arranged on both sides of the inner wall of the fermentation cabinet 1. A spring 308 is arranged in at least one of the sliding sleeves 302. The two ends of the spring 308 are respectively fixedly connected to the slider 306 and the sliding sleeve 302. The spring 308 can play a role of buffering and resetting during the reciprocating sliding and lifting process of the push rod 301.

[0039] By adopting the above design, when fermentation is carried out, the driving screw 305 can be driven to rotate by starting the motor 304 through the harmonic reducer 309. Since the driving screw 305 is threadedly connected to the sleeve 302 and the driving screw 305 is a reciprocating threaded rod, the sleeve 302 slides back and forth on the inner wall of the fermentation cabinet 1.

[0040] The push rod 301 in the sliding sleeve 302 moves with the sliding sleeve 302. Since its bottom end contacts the top surface of the wave plate 303 inside the sliding sleeve 302, the push rod 301 will slide back and forth and rise and fall along the top surface of the wave plate 303 during the forward and backward sliding process. When the push rod 301 moves upward, it will push the mesh 203, causing the wolfberry black tea on the mesh 203 to turn over, thereby promoting uniform fermentation and improving fermentation quality.

[0041] In addition, multiple placement components 2 and pushing components 3 are provided, which are distributed at intervals in the fermentation cabinet 1. Sprockets are provided on the driving screws 305 in the above-mentioned pushing components 3, and chains meshing with all the sprockets are laid on the sprockets of the top and bottom driving screws 305.

[0042] The arrangement of multiple placement components 2, pushing components 3 and sprocket chains enables the device to turn over tea leaves in multiple meshes 203 at the same time without increasing the driving source, thereby increasing the fermentation speed of the tea leaves by increasing the number of tea leaves fermented at the same time.

[0043] Furthermore, an adjusting component 4 is arranged below the wave plate 303, and the adjusting component 4 includes a partition 401 fixedly connected to the inner wall of the fermentation cabinet 1, a limiting sleeve 402 is arranged on the top surface of the partition 401, and a limiting block 403 is slidably connected in the limiting sleeve 402. The wave plate 303 is made of elastic material, and the top of the limiting block 403 is in contact with the wave crest of the wave plate 303. An adjusting screw 404 is radially rotatably arranged in the partition 401, and the adjusting screw 404 is threadedly connected to the limiting block 403.

[0044] The wave plate 303 is made of elastic material, so that it can be deformed. The limit block 403 can only be vertically slidably set in the limit sleeve 402, and is threadedly connected to the adjusting screw 404, and its top end contacts the wave crest of the wave plate 303, so that after rotating the adjusting screw 404, the top end of the limit block 403 can be driven to rise, contact the wave crest of the wave plate 303, and make the wave crest rise; when the top end of the limit block 403 drops, the wave crest of the wave plate 303 will also drop because it is made of elastic material and has its own resilience, so that the pushing amplitude of the push rod 301 can be adjusted, so as to prevent the thinner stacked tea from splashing out due to excessive pushing amplitude, and to prevent the thicker stacked tea from being unable to be pushed due to too small pushing amplitude, so as to adapt to various production needs.

[0045] There are multiple limit sleeves 402 distributed at intervals, and their positions correspond to the wave crest positions of the wave plate 303. A worm gear 405 is provided at the bottom end of the adjusting screw 404. A worm 406 is radially rotatably plugged into the back of the fermentation cabinet 1. The worm 406 is meshed with multiple worm gears 405 at the same time. One end of the worm 406 passes through the back of the fermentation cabinet 1 and a knob 408 is provided on it.

[0046] The design of the worm wheel 405 and the worm 406 allows the user to move to the back of the fermentation cabinet 1 when it is necessary to adjust the pushing amplitude of the push rod 301, and to simultaneously adjust the heights of the multiple limit blocks 403 in the pushing component 3 under the placement component 2 by rotating the worm 406 at the rear of the corresponding placement component 2, thereby making it more convenient to adjust the wave plate 303 in the device.

[0047] The design of the knob 408 increases the contact area and friction between the palm of the worker and the worm 406 when the worker rotates the worm 406, making it more convenient to apply force.

[0048] A top plate 407 is disposed at the top of the limiting block 403 . The top surface of the top plate 407 contacts the wave plate 303 , and the top surface of the top plate 407 is in an arc shape.

[0049] The top plate 407 is in an arc shape and can be adapted to the wave line formed by the wave plate 303, so that the wave crest is smoother, thereby improving the stability of the push rod 301 during operation.

[0050] Working principle: During the preparation stage, the wolfberry black tea to be fermented is placed on the mesh 203, and the mesh 203 is connected to the guide rails 201 on both sides of the inner wall of the fermentation cabinet 1 through the connecting frame 202. The guide blocks 204 on both sides of the connecting frame 202 and the rollers 205 at the lower end facilitate the sliding of the connecting frame 202 on the guide rails 201, thereby facilitating the placement and removal of tea leaves.

[0051] The sealed door 101 on the front of the fermentation cabinet 1 is closed, and the fermentation status can be observed at any time through the observation window 102 on the sealed door 101.

[0052] During the fermentation stage, the fermenter 501 is started through the control panel 5 on the side of the fermentation cabinet 1, the temperature and humidity in the fermentation cabinet 1 are adjusted, and the wolfberry black tea in the fermentation cabinet 1 is fermented.

[0053] At the same time, the motor 304 is started, and the drive screw 305 is driven to rotate through the harmonic reducer 309. Since the drive screw 305 is threadedly connected to the sleeve 302 and the drive screw 305 is a reciprocating threaded rod, the sleeve 302 slides back and forth on the inner wall of the fermentation cabinet 1.

[0054] The push rod 301 in the sliding sleeve 302 moves with the sliding sleeve 302. Since its bottom end contacts the top surface of the wave plate 303 inside the sliding sleeve 302, the push rod 301 will slide back and forth and rise and fall along the top surface of the wave plate 303 during the forward and backward sliding process. When the push rod 301 moves upward, it will push the mesh 203, causing the wolfberry black tea on the mesh 203 to turn over, thereby promoting uniform fermentation.

[0055] At least one sliding sleeve 302 is provided with a spring 308 , and the spring 308 can play a role of buffering and resetting during the reciprocating sliding and lifting process of the push rod 301 .

[0056] According to actual needs, the wave amplitude of the wave plate 303 can be adjusted by adjusting the component 4, and the knob 408 on the back of the fermentation cabinet 1 is rotated to drive the worm 406 to rotate. The worm 406 is meshed with multiple worm gears 405 at the same time, and the worm gear 405 drives the adjusting screw 404 to rotate. The adjusting screw 404 is threadedly connected with the limit block 403, and the limit block 403 slides in the limit sleeve 402. When the adjusting screw 404 rotates, the limit block 403 will rise and fall vertically in the limit sleeve 402.

[0057] Because the top plate 407 at the top of the limit block 403 contacts the crest of the wave plate 303, the crest height of the wave plate 303 can be changed by adjusting the height of the limit block 403, thereby adjusting the up and down movement amplitude of the push rod 301, and further adjusting the turning degree of the tea leaves in the mesh 203.
