Description

Technical Field

[0001] This utility model relates to the field of tea processing technology, specifically a tea fermentation barrel. Background Technology

[0002] Fermented tea is a type of tea processing technique. It refers to tea made from tea buds and leaves that have undergone initial processing such as withering, rolling, fermentation, and drying to produce raw tea, which is then further refined. Fermentation is a crucial step in the production of fermented tea. Traditionally, fermentation is done manually, with the tea leaves piled up for fermentation. The operator relies on their experience to judge the temperature and humidity of the pile, which can easily lead to uneven fermentation. Therefore, various fermentation equipment is used to assist or replace manual fermentation.

[0003] For example, the utility model with authorization announcement number CN211241569U discloses a tea fermentation barrel, including a fermentation barrel shell, a feeding funnel fixedly provided at the feeding port at the top of the fermentation barrel shell, a centrifugal inner liner provided inside the fermentation barrel shell, a connecting shaft fixedly provided at the bottom of the centrifugal inner liner, the connecting shaft passing through a bearing embedded in the bottom inner wall interlayer of the fermentation barrel shell and being connected to the output shaft of a drive motor, the drive motor being fixedly installed at the bottom of the fermentation barrel shell, and a water storage tank being fixedly provided on one side of the top of the fermentation barrel shell.

[0004] Taking the aforementioned tea fermentation barrel as an example, heat is directly transferred to the tea leaves through the heat-conducting metal, which can easily lead to uneven heating of the tea leaves inside the barrel. In addition, since the tea leaves themselves contain a certain amount of moisture, they are prone to sticking to the high-temperature metal during the contact process, which can easily result in burnt tea leaves. Utility Model Content

[0005] The purpose of this invention is to provide a tea fermentation barrel to solve the problem in the prior art where the tea leaves tend to stick to the high-temperature metal when heat is directly applied to the tea leaves through a heat-conducting metal.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a tea fermentation barrel, including an insulated outer shell, a fermentation tank rotatably connected inside the insulated outer shell, two diversion boxes fixedly embedded on one side of the insulated outer shell, multiple air guide grooves I on the outer side of each of the two diversion boxes, air guide groove II on one side of each of the multiple air guide grooves I, air guide groove III on one side of each of the multiple air guide grooves II, and a support component on the outer side of the insulated outer shell.

[0007] Preferably, one end of the fermenter located inside the insulation shell is fixedly connected to a transmission horizontal shaft, one end of which passes through the side wall of the insulation shell and is rotatably connected to the insulation shell. A drive motor is fixedly installed on the outside of the insulation shell, and the output end of the drive motor is fixedly connected to the transmission horizontal shaft.

[0008] Preferably, a brake is fixedly installed on the outside of the insulation shell, and the transmission shaft passes through the brake.

[0009] Preferably, an air guide box is fixedly connected between the two diversion boxes, and the air guide box is located on the outside of the insulation shell.

[0010] Preferably, the multiple air guide channels 2 are all opened inside the heat insulation shell, and the multiple air guide channels 3 are all opened outside the fermentation tank. The fermentation tank is fixedly connected to a discharge valve, a temperature sensor, a solenoid valve and a humidity sensor at one end of the heat insulation shell opening.

[0011] Preferably, the support assembly includes a grounding base disposed at the bottom of the insulation shell, a hydraulic cylinder fixedly connected to the top of the grounding base, a sliding frame fixedly connected to the piston end of the hydraulic cylinder, and a guide rail sleeved on the top of the outer side of the sliding frame, wherein the guide rail is fixedly installed at the bottom of the insulation shell.

[0012] Preferably, multiple supporting round shafts are fixedly connected to both sides of the heat insulation shell. The two supporting round shafts farthest from the opening end of the heat insulation shell are rotatably connected to the outer side of the shafts. Supporting vertical rods are provided at the bottom of the remaining supporting round shafts. The bottom end of the mounting frame and the bottom end of the supporting vertical rod are fixedly connected to the grounding base.

[0013] Compared with the prior art, the beneficial effects of this utility model are: 1. When this application is used, the control drive motor drives the fermentation tank to rotate. During the time when the air guide channel three and the air guide channel two are misaligned, the steam pressure inside the distribution box increases. When the air guide channel three and the air guide channel two are aligned, high-pressure steam enters the fermentation tank and heats and humidifies the tea leaves that are turned over due to the rotation of the fermentation tank. Through the cooperation of two distribution boxes, multiple air guide channels one, multiple air guide channels two, and multiple air guide channels three with the rotating fermentation tank, high-speed steam is continuously supplied to the fermentation tank while the fermentation tank rotates and turns over the tea leaves inside. This ensures that the temperature and humidity of the tea leaves in different positions inside the fermentation tank are uniform, ensuring the quality of tea fermentation. The high-speed steam with a certain humidity heats the tea leaves and prevents the tea leaves from sticking and burning on the inner wall of the fermentation tank.

[0014] 2. When using this application, the hydraulic cylinder is extended and extended. The hydraulic cylinder applies an upward force to the guide rail through the sliding frame. The insulation shell rotates around the support shaft that is rotatably connected to the mounting frame, causing the insulation shell to tilt. When the insulation shell tilts upward by 50°, the hydraulic cylinder stops working. At this time, the discharge valve is opened, and tea leaves can be added into the fermentation tank. The hydraulic cylinder is then retracted, causing the insulation shell to tilt downward by 30°. The discharge valve is then opened, and the fermented tea leaves inside the fermentation tank are poured out, ensuring quick and convenient loading and unloading of materials inside the fermentation tank.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Example: Figures 1-5 As shown, this utility model provides a technical solution for a tea fermentation barrel, including an insulated outer shell 3, a fermentation tank 6 rotatably connected inside the insulated outer shell 3, two diversion boxes 11 fixedly embedded on one side of the insulated outer shell 3, multiple air guide grooves 12 are opened on the outer side of the two diversion boxes 11, an air guide groove 13 is provided on one side of the multiple air guide grooves 12, an air guide groove 34 is provided on one side of the multiple air guide grooves 13, and a support component is provided on the outer side of the insulated outer shell 3.

[0019] Specifically, a fermentation tank 6 is rotatably connected inside the heat-insulating outer shell 3. One end of the fermentation tank 6, located inside the heat-insulating outer shell 3, is fixedly connected to a transmission horizontal shaft 7. One end of the transmission horizontal shaft 7 passes through the side wall of the heat-insulating outer shell 3, and the outer side of the transmission horizontal shaft 7 is rotatably connected to the heat-insulating outer shell 3. The output end of a drive motor 8, which is fixedly installed on the outer side of the heat-insulating outer shell 3, is fixedly connected to the transmission horizontal shaft 7. Therefore, the drive motor 8 is controlled to work, and the drive motor 8 drives the fermentation tank 6 to rotate inside the heat-insulating outer shell 3 through the transmission horizontal shaft 7. The rotation of the fermentation tank 6 has the effect of turning the tea leaves inside.

[0020] A brake 9 is fixedly installed on the outside of the heat insulation shell 3. The transmission horizontal shaft 7 passes through the brake 9. The brake 9 is controlled to brake the transmission horizontal shaft 7, and the fermentation tank 6 is braked. The relative position between the fermentation tank 6 and the heat insulation shell 3 cannot be changed.

[0021] Since the two diversion boxes 11 fixedly embedded on the heat insulation shell 3 are connected by a gas guide box 10, and the gas guide box 10 is located on the outside of the heat insulation shell 3 and connected to the steam generator outlet, controlling the steam generator to work can supply high-temperature steam with a certain water content to the gas guide box 10. The steam enters the two diversion boxes 11 under the diversion action of the gas guide box 10.

[0022] Multiple air guide slots 12 are provided on the outside of the distribution box 11. Air guide slots 2 13 are provided on one side of the multiple air guide slots 12 and are all located inside the heat insulation shell 3. Air guide slots 3 14 are provided on one side of the multiple air guide slots 2 13 and are all located on the outside of the fermentation tank 6. When the air guide slots 3 14 are aligned with the air guide slots 2 13, the inside of the distribution box 11 is connected to the inside of the fermentation tank 6 through the air guide slots 12, 2 13 and 3 14. When the air guide slots 3 14 are misaligned with the air guide slots 2 13, the connection between the distribution box 11 and the fermentation tank 6 is disconnected. The drive motor 8 drives the fermenter 6 to rotate. When the third air guide channel 14 aligns with the second air guide channel 13, the drive motor 8 stops working, the brake 9 engages, and the transmission horizontal shaft 7 brakes, preventing the fermenter 6 from moving. At this time, steam enters multiple locations inside the fermenter 6 through multiple air guide channels 12, 23, and 34, rapidly heating and humidifying the interior of the fermenter 6. The fermenter 6, located at the opening of the insulation shell 3, is fixedly connected to a discharge valve 17, a temperature sensor 18, a solenoid valve 19, and a humidity sensor 20. The temperature sensor 18 detects the internal temperature of the fermenter 6, and the humidity sensor 20 detects the internal humidity. When the internal temperature of the fermenter 6... Once the humidity reaches the preset value, the drive motor 8 is controlled to drive the fermentation tank 6 to rotate. During the time when the air guide channel 14 and the air guide channel 2 are staggered, the steam pressure inside the distribution box 11 increases. When the air guide channel 14 and the air guide channel 2 are aligned, high-pressure steam enters the fermentation tank 6 and heats and humidifies the tea leaves that are turned over due to the rotation of the fermentation tank 6. Through the cooperation of the two distribution boxes 11, multiple air guide channels 12, multiple air guide channels 2 13, and multiple air guide channels 3 14 with the rotating fermentation tank 6, high-speed steam is continuously supplied to the fermentation tank 6 while the fermentation tank 6 rotates and turns the tea leaves inside, ensuring that the temperature and humidity of the tea leaves in different positions inside the fermentation tank 6 are uniform and ensuring the quality of tea fermentation.

[0023] In addition, when the internal pressure of the fermenter 6 reaches the pressure relief threshold of the solenoid valve 19, the solenoid valve 19 is opened by the gas inside the fermenter 6, the internal pressure of the fermenter 6 is relieved, and the internal pressure of the fermenter 6 is kept stable.

[0024] In the support assembly, the grounding base 1 is located at the bottom of the insulation shell 3. The piston end of the hydraulic cylinder 23, which is fixedly connected to the top of the grounding base 1, is fixedly connected to the sliding frame 22. The guide rail 21, which is sleeved on the top of the outer side of the sliding frame 22, is fixedly installed at the bottom of the insulation shell 3. Since most of the spherical structure at the top of the sliding frame 22 is located inside the guide rail 21, the sliding frame 22 can rotate relative to the guide rail 21 within a certain angle range without separating from the guide rail 21.

[0025] Furthermore, since multiple supporting shafts 4 are fixedly connected to both sides of the insulation shell 3, and mounting brackets 5 are rotatably connected to the outer sides of the two supporting shafts 4 furthest from the opening end of the insulation shell 3, and supporting vertical rods 2 are provided at the bottom of the remaining supporting shafts 4, when the insulation shell 3 is kept parallel to the grounding base 1, the two mounting brackets 5 and multiple supporting vertical rods 2 fixedly connected to the grounding base 1 support the multiple supporting shafts 4, and the weight of the insulation shell 3 is applied to the supporting vertical rods 2 and the grounding base 1. When tea leaves need to be added into the fermentation tank 6, the drive motor 8 is activated to rotate the fermentation tank 6. When the discharge valve 17 rotates to the top position, the drive motor 8 stops working, and the brake 9 is activated to brake the fermentation tank 6, maintaining the relative position between the fermentation tank 6 and the insulation shell 3. Then, the hydraulic cylinder 23 is activated to extend, and the hydraulic cylinder 23 applies an upward force to the guide rail 21 through the sliding frame 22. The insulation shell 3 rotates around the support shaft 4, which is rotatably connected to the mounting frame 5, causing the insulation shell 3 to tilt. When the insulation shell 3 tilts upward by 50°, the hydraulic cylinder 23 stops working. At this time, the discharge valve 17 is opened, and tea leaves can be added into the fermentation tank 6.

[0026] Similarly, after the drive motor 8 and brake 9 work together to move the discharge valve 17 to the bottom position, the hydraulic cylinder 23 is controlled to retract, causing the insulation shell 3 to tilt down 30°. Then, the discharge valve 17 is controlled to open, allowing the fermented tea leaves inside the fermentation tank 6 to be poured out, ensuring quick and convenient loading and unloading of materials inside the fermentation tank 6.

Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
