Description

Technical Field

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

[0002] The fermentation of tea is a key step in the tea making process to achieve the transformation of tea quality through enzymatic oxidation. Tea fermentation is essentially a process in which polyphenols inside the tea (such as catechins) undergo oxidation reaction under the action of enzymes. The fermentation process is to place the rolled tea leaves in a suitable temperature and humidity environment for natural aerobic fermentation, allowing the components inside the tea to undergo enzymatic oxidation to form substances such as theaflavins, thearubigins and theabrownins, so that the aroma, color and taste of the tea are fully developed.

[0003] At this stage, the tea leaves need sufficient oxygen to carry out the enzymatic oxidation reaction. At the same time, during the fermentation, the tea leaves will release heat, and a high-temperature, oxygen-deficient environment is likely to form inside the tea pile, which is easy to become suffocated and affect the normal progress of the fermentation. It is necessary to pay attention to the state of the tea leaves at all times and turn them over many times to ensure that the tea leaves can be evenly and fully exposed to oxygen. At the same time, the temperature and heat are reduced to prevent the high temperature from causing the enzymatic reaction to be too fast and the fermentation to end prematurely, thereby improving the stability of the fermentation. The existing fermentation process requires workers to frequently turn the pile, which is a huge workload. Moreover, turning the pile according to experience will result in uneven fermentation quality. Based on this, a controllable tea fermentation device and a fermentation method thereof are proposed.

[0011] As a preferred embodiment, the magnetic control device includes an electric push rod arranged in the flip slide, the end of the electric push rod is fixedly connected to the inclined push block, a rectangular opening is opened in the flip slide, and a joint control rack is slidably arranged on the inner wall of the rectangular opening, and the end of the joint control rack is inclined;

[0012] A receiving opening is provided on the upper surface of the flip slide, the flip rod is located in the receiving opening and is rotatably connected to the inner wall of the receiving opening via a connecting shaft, and a linkage tooth layer meshing with the linkage rack is fixedly provided on the flip rod.

[0013] As a preferred solution, the end of the linkage rack extends outward and is fixedly connected to a reset plate, and the reset plate is connected to the side wall of the flip slide through a reset spring.

[0014] As a preferred solution, the magnetron plate includes positive magnetic plates and negative magnetic plates evenly arranged on the side wall of the circumferential cover, and the positive magnetic plates and negative magnetic plates are arranged alternately.

[0015] As a preferred solution, the eccentric transmission assembly includes a transmission port opened in the collection cover, an eccentric disk connected to the output end of the direct drive motor is provided in the transmission port, an eccentric rod is eccentrically provided on the eccentric disk, and the end of the eccentric rod is rotatably connected to the bottom end of the reciprocating rod;

[0016] A vertical movement limit block is fixedly connected to the inner wall of the transmission port, and a limit port adapted to the vertical movement limit block is opened on the reciprocating movement rod.

[0017] A fermentation method comprises the following steps:

[0018] S1. Tea rolling preparation: The tea leaves are selected and sorted, and then rolled to break the cell walls of the tea leaves, exposing the catechins originally present in the cell fluid to the outside of the cells;

[0019] S2, tea turning enzymatic reaction: a certain mass of rolled tea leaves are piled on a fermentation mesh plate for initial fermentation.

[0023] As a preferred solution, S2 can increase the temperature of the tea leaves in the stack during the uniform turning process, accelerate the enzymatic reaction, and also provide sufficient contact with external oxygen after turning the tea leaves, providing oxygen supply for the enzymatic reaction and ensuring that the tea leaves can be evenly fermented.

[0024] Compared with the prior art, the present invention has the following beneficial effects:

[0025] 1. The present invention realizes automatic turning of tea leaves through the linkage between positive and negative magnetic plates and magnetic suction parts and the mechanical action of the turning rod, completely replacing traditional manual operation and eliminating the problem of uneven fermentation caused by differences in human experience.

[0026] 2. In the later stage of tea fermentation, the present invention drives the eccentric disk to move up and down by the direct-drive motor, and under the magnetic attraction of the magnetic control plate and the magnetic component, the fermentation net disk is driven to expand and contract and vibrate to achieve uniform heat dissipation of the tea leaves, stabilize the temperature of the tea pile within an appropriate range, and avoid high temperature-induced enzymatic reaction out of control. The gravity depression design of the flip slide cooperates with the shaking action to effectively disperse the stacking density of the tea leaves and reduce the risk of local high-temperature suffocation.

[0039] Example, see Figures 1 to 8 A controllable tea fermentation device includes a fermentation chamber, which consists of a collecting base 1, support end plates 2 on both sides and a circumferential cover 3. The support end plate 2 is connected to a circulating belt 4 through an intermittent drive device. Furthermore, the intermittent drive device includes an intermittent motor 16 arranged on the support end plate 2, and the support end plate 2 is rotated by a rotating shaft and is provided with two transmission pulleys 17. The output end of the intermittent motor 16 is fixedly connected to the transmission pulley 17 located above, and the two transmission pulleys 17 are connected by a circulating toothed belt 18 for transmission, and the circulating toothed belt 18 is fixedly connected to the circulating belt 4.

[0040] A plurality of tea fermentation trays are evenly arranged between the two circulating belts 4. The tea fermentation trays include a fermentation tray frame 5. Both ends of the fermentation tray frame 5 are rotatably connected to the circulating belt 4 through a rotating shaft 6. The rotational connection between the rotating shaft 6 and the fermentation tray frame 5 can ensure that when the circulating belt 4 drives the tea fermentation tray to move, the tea fermentation tray is always kept in a horizontal state under the action of the counterweight stabilizing plate 7;

[0041] The fermentation tray frame 5 is provided with a counterweight stabilizing plate 7 at both ends, and a retractable fermentation net plate 8 is provided on the fermentation tray frame 5. Both ends of the fermentation net plate 8 are connected to the fermentation tray frame 5 through a retractable member;

[0042] Furthermore, the telescopic part includes a connecting end seat 19 arranged on the side wall of the fermentation tray frame 5, the connecting end seat 19 is fixedly connected to the torsion inner shaft 20, the torsion inner shaft 20 is connected to the winding drum 21 through a torsion spring, and the two ends of the fermentation net tray 8 are respectively wound and connected to the winding drum 21.

[0043] It should be noted that the winding drum 21 has a winding force to retract the fermentation net tray 8 to both sides under the action of the torsion spring.

[0044] A flip slide 9 is movably provided on the fermentation net plate 8. The flip slide 9 itself has gravity, which will cause the fermentation net plate 8 to be concave in the middle of the fermentation net plate 8, thereby ensuring that the tea leaves can be stacked in the concave place. A plurality of flip rods 10 are controlled by a magnetic control device on the flip slide 9. Furthermore, the magnetic control device includes an electric push rod 22 arranged in the flip slide 9, and the end of the electric push rod 22 is fixedly connected to a bevel push block 23. A rectangular opening is opened in the flip slide 9, and a linked control rack 24 is slidingly provided on the inner wall of the rectangular opening. The end of the linked control rack 24 is inclined, and the end of the linked control rack 24 extends outward and is fixedly connected to a reset plate 26. The reset plate 26 is connected to the side wall of the flip slide 9 through a reset spring.

[0045] A receiving opening is provided on the upper surface of the flip slide 9 , in which the flip rod 10 is located and is rotatably connected to the inner wall of the receiving opening via a connecting shaft. A linkage tooth layer 25 meshing with the linkage rack 24 is fixedly provided on the flip rod 10 .

[0046] The electric push rod 22 drives the inclined push block 23 set at its output end to move, thereby moving the joint control racks 24 on both sides. The movement of the joint control racks 24 will drive the turning rod 10 originally in the storage port to unfold, increasing the contact area with the tea leaves, thereby ensuring the turning effect of the tea leaves.

[0047] A magnetic component 11 is provided at the bottom of the flip slide 9, and a magnetic control plate that works together with the magnetic component 11 is provided on the inner wall of the circumferential cover 3. The magnetic control plate includes a positive magnetic plate 27 and a negative magnetic plate 28 evenly arranged on the side wall of the circumferential cover 3, and the positive magnetic plate 27 and the negative magnetic plate 28 are arranged alternately.

[0048] It should be noted that when the magnetic element 11 is attracted to the positive magnetic plate 27 and repelled by the negative magnetic plate 28, when the circulating belt 4 drives the tea fermentation disk to move, when passing through the magnetic control plate, under the action of the positive magnetic plate 27 and the negative magnetic plate 28, the flipping slide 9 will be driven to move left and right on the fermentation net disk 8, and the flipping rod 10 arranged on the flipping slide 9 will flip the tea leaves left and right, thereby ensuring that the fermenting tea leaves can be evenly heated and fully exposed to oxygen.

[0049] The collecting base 1 is provided with a collecting cover 12 for guiding the broken leaves to both sides. The fermentation net disk 8 is designed with a mesh structure. In the process of shaking and dissipating heat of the tea leaves, the fermented broken tea can be screened through the mesh structure. Under the action of the collecting cover 12, the broken leaves can be guided to both sides, which is convenient for the subsequent collection and processing of the broken leaves. A direct drive motor 13 is provided in the collecting cover 12. The direct drive motor 13 is connected to a reciprocating rod 14 through an eccentric transmission assembly, and a magnetic control board 15 is connected to the top of the reciprocating rod 14.

[0050] Furthermore, the eccentric transmission assembly includes a transmission port provided in the collection cover 12, an eccentric disc 29 connected to the output end of the direct drive motor 13 is provided in the transmission port, an eccentric rod 30 is eccentrically provided on the eccentric disc 29, and the end of the eccentric rod 30 is rotatably connected to the bottom end of the reciprocating rod 14;

[0051] A vertical movement limit block 31 is fixedly connected to the inner wall of the transmission opening, and a limit opening 32 adapted to the vertical movement limit block 31 is formed on the reciprocating rod 14 .

[0052] Under the action of the eccentric transmission assembly, the reciprocating rod 14 can be driven to move up and down by the eccentric rod 30 during the rotation of the eccentric disk 29. The magnetic control plate 15 arranged on the reciprocating rod 14 will generate suction to the magnetic component 11, thereby driving the fermentation network disk 8 to concave downward and then release it instantly, thereby achieving effective shaking and heat dissipation of the tea leaves on the fermentation network disk 8.

[0053] A fermentation method proposed by a controllable tea fermentation device comprises the following steps:

[0054] The tea leaves are selected and sorted, and then rolled to break the cell walls of the tea leaves, exposing the catechins originally present in the cell fluid to the outside of the cells;

[0055] A certain mass of rolled tea leaves are piled on the fermentation mesh plate 8 for initial fermentation. During the fermentation process, the tea leaves on the fermentation mesh plate 8 are driven by the circulating belt 4 for circulation. During the circulation process, the cooperation between the magnetic control plate and the magnetic suction member 11 realizes the continuous and uniform turning of the tea leaves.

[0056] During the uniform turning process, the temperature of the tea leaves can be raised in the stack, accelerating the enzymatic reaction. After the tea leaves are turned, they can be fully exposed to external oxygen, providing oxygen supply for the enzymatic reaction and ensuring uniform fermentation of the tea leaves.

[0057] In the later stage of tea fermentation, when the fermenting tea leaves are moved to the collecting base 1 below by the circulating belt 4, the turning slide 9 is continuously driven up and down by the action of the magnetic control board 15 and the magnetic member 11, so that the fermentation net plate 8 shakes and drives the tea leaves to shake and dissipate heat, thereby reducing the temperature of the tea pile, preventing the high temperature from causing the enzymatic reaction to speed up too much and ending the fermentation prematurely, thereby improving the stability of the fermentation;

[0058] The tea leaves in the fermentation net tray 8 will be fermented in a centralized manner in the fermentation chamber. The closed environment of the fermentation chamber is conducive to the accumulation and precipitation of flavor substances, which helps to accumulate the tea aroma and release the flavor.

[0059] After the fermentation of the entire batch of tea is completed, the fermentation room is opened and the fermented tea is sealed and packaged to prevent the loss of flavor substances;

[0060] The present invention replaces manual experience judgment with mechanical automation, realizes standardized control of the fermentation process, and effectively solves core problems in traditional processes such as uneven temperature, unstable oxygen supply, and large manual errors.

[0061] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
