Description

Technical Field

[0001] The invention relates to the technical field of stirring devices, in particular to a uniform stirring device for tea fermentation. Background Art

[0002] Tea fermentation is an important part of tea processing. For black tea and other teas, the quality of the fermentation directly affects the quality of the tea. During the fermentation process, the chemical substances in the tea will change, producing new flavors and aromas. Therefore, ensuring that the tea can be evenly heated and reacted during the fermentation process is the key to obtaining high-quality tea. During the tea fermentation process, uniform stirring of the tea is crucial. Stirring can make the tea more evenly distributed in the fermentation container, avoiding local overheating or insufficient reaction caused by tea accumulation. At the same time, stirring can also promote the exchange of substances between tea leaves and accelerate the fermentation process.

[0003] During the tea fermentation and stirring process, the fermenting tea leaves are piled up together, which may cause local overheating and insufficient contact area between the tea leaves and oxygen and water, resulting in insufficient reaction and deterioration of tea quality. In addition, if the inside of the stirring device is not cleaned in time after the discharge is completed, the remaining leaves inside may dry up and then stick to the inside of the stirring device, making it difficult to clean. At the same time, the remaining leaves may also affect the next tea fermentation. Summary of the invention

[0024] In summary, due to the use of the above-mentioned technology, the uniform stirring device for tea fermentation has the following beneficial effects:

[0025] 1. Through the cooperation between the stirring component, the fermentation component and the gear ring, the tea leaves in the inner cavity of the groove of the collecting block can freely fall from the top of the inner cavity of the fermentation tube through the cooperation with the matching rod during the positive rotation of the two collecting components, thereby avoiding the problem of tea leaves accumulation during the stirring process. At the same time, the collecting component pushes the tea leaves between the fermentation tube and the matching arc plate to make an arc motion, thereby increasing the contact area between the tea leaves and oxygen, and the contact area between the tea leaves and water and oxygen, thereby promoting the mixing reaction of the substances inside the tea leaves and improving the fermentation rate.

[0026] 2. The device can evenly replenish water to the tea leaves and stir the tea leaves more evenly through the cooperation between the pushing component, the vibrating bucket, the stirring component, the collecting component and the spraying component. The tea leaves are pushed from the collecting plate by the pushing plate so that they fall evenly and dispersedly on the vibrating bucket. In the process of the tea leaves falling, the tea leaves are evenly sprayed with water, the contact area between the tea leaves and the water is increased, and water can be evenly replenished, avoiding the concentration of water in one area to damage the tea leaves. In addition, the stirring rack disperses and mixes the tea leaves that fall into the inner cavity of the stirring tube, and then falls back on the inner surface of the fermentation tube, so that the collecting component can stir more evenly.

[0027] 3. Through the cooperation between the stirring component, the fermentation component and the gear ring, the collecting component can discharge the tea leaves from the inner cavity of the fermentation tube through the gear ring while cleaning the inner wall of the fermentation tube during the reverse rotation of the two collecting components. The two collecting components are reversed, so that the connecting plate rotates with the limit plate to release the blocked sealing plate, so that the tea leaves in the inner cavity of the fermentation tube can be automatically discharged. As the unidirectional rotating gear engages and rotates with the gear ring, the cleaning roller can rotate to clean the inner cavity of the fermentation tube and clean the leaves remaining on the inner surface of the fermentation tube, thereby preventing the residual leaves from affecting the next fermentation.

[0028] 4. Through the cooperation between the screening components, transmission components, stirring components and fermentation components, the device can screen the discharged tea leaves and remove the debris in the tea leaves to improve the quality of the tea leaves during the reverse rotation of the two collecting components. By reversing the control motor, the sealing plate is opened, and the tea leaves in the inner cavity of the fermentation tube fall on the upper end of the screen as the collecting component rotates. The eccentric wheel rotates as the collecting component rotates in the opposite direction. The eccentric wheel can push the push plate, causing the push plate to shake with the screen, thereby screening the tea leaves on the screen, removing impurities and improving the purity of the tea leaves.

A stirring component 50 matched with the fermentation component 60 is installed on the upper side of the collection box 10. The stirring component 50 is used to stir the fermented tea leaves in the fermentation component 60. A toothed ring 40 matched with the stirring component 50 is fixed to the inner cavity of the collection box 10. The toothed ring 40 is fixed by two brackets.

[0053] The liquid spraying component 20 includes a water tank, a water pump and a spray nozzle, which is used to spray water or fermentation liquid into the fermentation component 60 according to the needs of fermentation, so that the temperature and humidity of the fermentation can reach a suitable fermentation state.

[0054] Further, if Figure 4 As shown, the stirring component 50 includes a control motor 57 and a fixed shaft 52. The control motor 57 is fixed to one end of the collection box 10. The output end of the control motor 57 is fixedly connected to the fixed shaft 52. The fixed shaft 52 passes through a support plate and is rotatably connected to the support plate. The support plate is fixed to the upper end of the collection box 10 to support the fixed shaft 52. The outer surface of the fixed shaft 52 is fixed with a first bevel gear 51 that is compatible with the transmission component 12.

[0055] Next, a connecting plate 53 is fixedly installed on the outer surface of the fixed shaft 52 through a one-way bearing. The control motor 57 rotates in the forward direction. The fixed shaft 52 will not rotate with the connecting plate 53 under the action of the one-way bearing. The connecting plate 53 is fixed with a limit plate 56 at one end away from the fixed shaft 52. The control motor 57 rotates in the reverse direction. The fixed shaft 52 rotates with the connecting plate 53 under the action of the one-way bearing, so that the limit plate 56 rotates with the connecting plate 53. A rotating circular plate 54 is fixed at one end of the fixed shaft 52 away from the control motor 57. Two collecting components 55 in an annular array are provided at one end of the rotating circular plate 54 away from the control motor 57. The collecting components 55 are fixed on the rotating circular plate 54.

[0056] Further, if Figure 5 and Figure 6 As shown, the collecting component 55 includes a collecting block 551, which is fixed on the rotating circular plate 54. The upper side of the collecting block 551 is provided with a Figure 6 The groove shown in the figure is convenient for collecting tea leaves. The inner cavity of the groove of the collecting block 551 is connected to the arc plate 552 by a torsion spring. The arc plate 552 is not squeezed as shown in FIG. Figure 6 As shown, the movable end is in a tilted state, a cleaning groove 557 is provided at one end of the collecting block 551 away from the arc plate 552, a connecting shaft 554 is rotatably installed in the inner cavity of the cleaning groove 557, one end of the connecting shaft 554 passes through the rotating circular plate 54 and is rotatably connected to the rotating circular plate 54 at the penetration point, a cleaning roller 555 is fixed on the outer surface of the connecting shaft 554, and a scraper 556 is fixed at one end of the collecting block 551 for pushing and unloading tea leaves when rotating in the reverse direction;

[0057] Among them, a gear 553 is installed on the side of the outer surface of the connecting shaft 554 close to the control motor 57 through a one-way bearing, and the gear 553 is adapted to the gear ring 40. During the forward rotation of the collecting component 55, due to the action of the one-way bearing, the gear 553 rolls on the surface of the gear ring 40, and the connecting shaft 554 does not rotate. During the reverse rotation of the collecting component 55, the gear 553 rotates on the surface of the gear ring 40, and at the same time drives the connecting shaft 554 to rotate, so that the cleaning roller 555 rotates.

[0058] Further, if Figure 7 and Figure 8 As shown, the fermentation component 60 includes a fixed circular plate 61 and a driving motor, the driving motor is fixedly mounted at one end of the collecting box 10, the fixed circular plate 61 is fixed to the side wall of the inner cavity of the collecting box 10 away from the stirring component 50, a feeding port is provided on the fixed circular plate 61, a fermentation tube 62 is fixed at one end of the fixed circular plate 61, and the bristles on the surface of the cleaning roller 555 are in contact with the inner surface of the fermentation tube 62, and the tea residues remaining on the inner surface of the fermentation tube 62 can be cleaned when the cleaning roller 555 rotates;

[0059] Next, a sealing plate 66 mounted on the fixed circular plate 61 is provided on the outer surface of the fermentation tube 62. The sealing plate 66 is installed on the discharge port opened on the outer surface of the fermentation tube 62. The sealing plate 66 is rotatably connected to the fixed circular plate 61 through a torsion spring. In a natural state, the sealing plate 66 is not closed with the fermentation tube 62, so that the tea leaves in the inner cavity of the fermentation tube 62 can slide out. When the limit plate 56 is reversed, the sealing plate 66 can automatically pop open, so that the tea leaves in the inner cavity of the fermentation tube 62 can be automatically discharged. A matching rod 63 is fixed at one end of the fixed circular plate 61, and a notched circular tube 65 is fixed at one end of the fixed circular plate 61. A discharge groove is opened on the outer surface of the notched circular tube 65, and a matching arc plate 64 is fixed at one end of the opening of the notched circular tube 65.

[0060] The collecting component 55 is matched with the fermentation tube 62 and the notched circular tube 65. The collecting component 55 is located between the inner surface of the fermentation tube 62 and the outer surface of the notched circular tube 65. When the collecting component 55 rotates, the inner surface of the arc plate 552 contacts the outer surface of the notched circular tube 65, so that the arc plate 552 rotates to the inner cavity of the groove of the collecting block 551, and collects the tea leaves into the inner cavity of the groove of the collecting block 551.

[0061] In addition, the collecting component 55 cooperates with the matching rod 63 and the matching arc plate 64, and the collecting component 55 rotates to the upper part of the fermentation tube 62, and the matching rod 63 will catch the gear 1 553, so that the gear 1 553 is reversed. Fig.12 As shown, the tea leaves in the inner cavity of the groove of the collecting block 551 will fall freely. In addition, the matching arc plate 64 will make the arc plate 552 contact with the matching arc plate 64 during the rotation of the collecting component 55, so that the arc plate 552 rotates to the inner cavity of the groove of the collecting block 551.

[0062] Next, a pushing component 67 is fixed to one side of the inner surface of the notched circular tube 65. The pushing component 67 is used to push the tea leaves and is used in conjunction with the liquid spraying component 20. A vibrating bucket 68 is provided at the lower side of the pushing component 67. The vibrating bucket 68 is fixedly mounted on the inner surface of the notched circular tube 65, but a certain gap is left for vibration. Two vibrating motors are fixed at the lower end of the vibrating bucket 68 to shake the vibrating bucket 68, so as to facilitate the tea leaves received by the vibrating bucket 68 to be sent into the stirring component 69. A stirring component 69 adapted to the vibrating bucket 68 is fixed to the inner surface of the notched circular tube 65.

[0063] Among them, a through groove adapted to the liquid spraying component 20 is opened on the fixed circular plate 61, so that the water sprayed by the liquid spraying component 20 can evenly contact the tea leaves falling from the pushing component 67, avoiding soaking of the tea leaves during humidification while ensuring that the tea leaves have sufficient moisture.

[0064] Specifically, Fig. 9 and Fig.10As shown, the pushing member 67 includes a fixing plate 671, which is fixed to the inner surface of the notched circular tube 65, and when the width of the fixing plate 671 is sufficient, the collecting member 55 will not be stuck in the material trough on the outer surface of the notched circular tube 65 when rotating. A collecting plate 674 is fixed to one end of the fixing plate 671, and the collecting plate 674 is inclined near one end of the vibration bucket 68 to facilitate the tea leaves to be dispersed and slide down;

[0065] Among them, a baffle is fixed on the upper end of the fixed plate 671, and a reciprocating screw 672 is rotatably installed on one end of the baffle. The outer surface of the reciprocating screw 672 is provided with a push plate 673 that slides on the upper end of the collecting plate 674. The reciprocating screw 672 rotates to make the push plate 673 reciprocate on the upper end of the collecting plate 674. When one of the collecting components 55 rotates one hundred and eighty degrees, the push plate 673 will reciprocate on the collecting plate 674 one back and forth, so that the tea leaves collected by the collecting component 55 can be pushed toward the vibrating bucket 68 by the push plate 673 after falling freely.

[0066] Then, if Fig. 9 and Fig.10 As shown, the stirring component 69 includes a stirring tube 691, which is fixed between the fixed plate 671 and the fixed circular plate 61. A feed trough and a discharge trough are respectively provided on the upper and lower sides of the outer surface of the stirring tube 691. The feed trough is aligned with the vibration bucket 68, so that the tea leaves passing through the vibration bucket 68 are immersed in the inner cavity of the stirring tube 691. The discharge trough and the discharge trough on the notched circular tube 65 are at the same position, which is convenient for discharging the tea leaves in the inner cavity of the stirring tube 691. The inner cavity of the stirring tube 691 is rotatably connected with a stirring frame 692, and the stirring frame 692 is tightly attached to the inner wall of the stirring tube 691, so that the tea leaves can be evenly dispersed and thinned, and then stirred. The stirring frame 692 is fixedly connected to the output end of the driving motor, and the stirring frame 692 is connected to the reciprocating screw 672 by a belt.

[0067] When the two collecting components 55 rotate forward in the inner cavity of the fermentation tube 62, the tea leaves collected by the collecting components 55 can fall freely from the top of the inner cavity of the fermentation tube 62 through the cooperation rod 63; and then cooperate with the pushing component 67 to make the tea leaves thinner and fall evenly from the upper end of the collecting plate 674 again, so that the contact area between the tea leaves and water and oxygen is increased, thereby improving the fermentation efficiency;

[0068] Next, when the two collecting components 55 rotate in the opposite direction in the inner cavity of the fermentation tube 62, the collecting components 55 can discharge the tea leaves in the inner cavity of the fermentation tube 62 through the gear ring 40 while cleaning the inner wall of the fermentation tube 62. The two collecting components 55 are reversed, so that the connecting plate 53 rotates with the limiting plate 56 to release the blocked sealing plate 66, so that the tea leaves in the inner cavity of the fermentation tube 62 can be automatically discharged, and as the unidirectional rotating gear 553 engages and rotates with the gear ring 40, the cleaning roller 555 can rotate to clean the inner cavity of the fermentation tube 62.

[0069] Embodiment 2

[0070] This embodiment further defines the screening component 11 and the transmission component 12 on the basis of the first embodiment, so as to achieve the purpose of screening the fermented tea leaves while feeding the tea leaves into the inner cavity of the fermentation tube 62 .

[0071] Specifically, Fig.11 As shown, the screening component 11 includes a mounting plate 111, which is fixed to the bottom wall of the inner cavity of the collecting box 10. A screen 112 is provided at one end of the mounting plate 111. The screen 112 passes through the mounting plate 111 and is movably mounted with the mounting plate 111. The screen 112 is installed at an angle. A push plate 113 is fixed to one end of the screen 112 close to the first bevel gear 51. A plurality of supporting springs are fixed between one end of the push plate 113 close to the mounting plate 111 and the mounting plate 111 for resetting the movable screen 112.

[0072] Further, if Fig.11 As shown, the transmission component 12 includes a fixed block 121, a transmission shaft 122 is provided at the upper end of the fixed block 121, the transmission shaft 122 penetrates the fixed block 121, and the transmission shaft 122 is fixedly installed with the fixed block 121 through a one-way bearing. The control motor 57 rotates forward, and the transmission shaft 122 is idling. The control motor 57 rotates reversely, and the transmission shaft 122 rotates with the eccentric wheel 124. The top of the transmission shaft 122 is fixed with a second bevel gear 123 meshing with the first bevel gear 51, and the lower end of the transmission shaft 122 is eccentrically fixed with an eccentric wheel 124. The eccentric wheel 124 is adapted to the push plate 113. When the eccentric wheel 124 rotates, the push plate 113 can be pushed, so that the screen 112 can screen the tea leaves.

[0073] It should be noted that the screen 112, eccentric wheel 124, liquid spray component 20, oxygenator 30, cleaning roller 555, vibrating bucket 68 and stirring frame 692 in the present invention are all prior arts, and their installation methods and control methods are also conventional designs, which will not be elaborated in detail in the present invention.

[0074] Working principle of the present invention: When the device is used, firstly, tea leaves to be fermented are put into the inner cavity of the fermentation tube 62 from the feeding port on the fixed circular plate 61, and then the control motor 57 is started to rotate in the forward direction. Fig.12 As shown, the rotating circular plate 54 rotates with the two collecting components 55 in the inner cavity of the fermentation component 60, wherein the collecting component 55 on the lower side pushes the tea leaves between the fermentation tube 62 and the matching arc plate 64 to make an arc motion, thereby increasing the contact area between the tea leaves and oxygen;

[0075] When the collecting component 55 rotates to the upper side of the opening of the notched circular tube 65, the notched circular tube 65 no longer applies pressure to the arc plate 552, so that the arc plate 552 rotates and opens under the action of the torsion spring, and the tea leaves in the inner cavity of the groove of the collecting block 551 fall from the upper side to the upper end of the collecting plate 674. Then the collecting component 55 continues to rotate, and the matching rod 63 clamps the arc plate 552, so that the arc plate 552 turns over, and the tea leaves in the inner cavity of the groove of the collecting block 551 freely fall from the upper part of the fermentation tube 62 to the upper end of the collecting plate 674. In this process, the contact area between the tea leaves and oxygen can be increased, and the mixing reaction of the substances inside the tea leaves can also be promoted.

[0076] Next, the push plate 673 starts to move after the tea leaves fall, pushing the tea leaves on the upper end of the collecting plate 674 toward the vibrating bucket 68. One end of the collecting plate 674 is inclined, so that the pushed tea leaves fall evenly. In the process of the tea leaves falling, the tea leaves are easily replenished with water by cooperating with the liquid spraying component 20, and the water sprayed on the tea leaves is more even.

[0077] Then, if Fig. 9 and Fig.10 As shown, the tea leaves fall on the vibration bucket 68, and fall into the inner cavity of the stirring tube 691 after being shaken by the vibration bucket 68. The stirring frame 692 disperses and mixes the fallen tea leaves, and then falls from the discharge trough and the lower trough onto the inner surface of the fermentation tube 62, and is again stirred and mixed by the collection component 55, so that the tea leaves are stirred more evenly;

[0078] After fermentation is completed, the motor 57 is controlled to rotate in the reverse direction. Fig.13 As shown, the rotating circular plate 54 rotates with the two collecting components 55 in the opposite direction, and at the same time, the fixed shaft 52 rotates with the connecting plate 53, so that the limit plate 56 also starts to rotate. At this time, the sealing plate 66 opens under the action of the torsion spring, and the tea leaves in the inner cavity of the fermentation tube 62 can slide down to the upper end of the screen 112 along the outlet where the sealing plate 66 is located;

[0079] During the reverse rotation of the two collecting components 55, the scraper 556 can push the tea leaves in the inner cavity of the fermentation tube 62, so that the tea leaves in the inner cavity of the fermentation tube 62 can be discharged from the discharge port where the sealing plate 66 is located. At the same time, during the rotation of the collecting component 55, the gear 1 553 meshes with the gear ring 40 and rotates, driving the connecting shaft 554 to rotate, thereby rotating the cleaning roller 555 to clean the inner surface of the fermentation tube 62, so that the collecting component 55 can clean the inner surface of the fermentation tube 62 while unloading the tea leaves.

[0080] Then, under the action of the first bevel gear 51 and the second bevel gear 123, when the control motor 57 rotates in the opposite direction, the transmission shaft 122 rotates with the eccentric wheel 124. During the rotation of the eccentric wheel 124, the push plate 113 is pushed. The push plate 113 is reset under the action of the supporting spring, and the continuous reciprocating movement allows the screen 112 to screen the tea leaves and improve the quality of the tea leaves.

[0081] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacement or changes to a uniform stirring device for tea fermentation and its inventive concept according to the technology of the present invention, which should be covered by the protection scope of the present invention.
