Black tea fermentation device with stirring function

Abstract

This utility model discloses a black tea fermentation device with a stirring function, belonging to the field of black tea fermentation technology. It includes a fermentation box with a stirring and discharging mechanism inside. The device also includes a receiving component. When the black tea fermentation is complete and discharge is required, two electric push rods on the moving plate are activated. The electric push rods drive the two moving plates to move in opposite directions along the moving groove. The movement of the moving plates causes the receiving box to move out of the fermentation box, and the discharged black tea falls into the separating mesh frame. Any remaining branches and leaves mixed in with the black tea fall through the holes in the separating mesh frame into the bottom wall of the receiving box. Then, the top frame moves upward, moving it away from the support block. The movement of the top frame causes the separating mesh frame to move away from the receiving box. The black tea and remaining branches and leaves in the separating mesh frame and the bottom wall of the receiving box are then processed separately, facilitating the separation and collection of the black tea and any remaining branches and leaves mixed in with it, thus ensuring the quality of the collected black tea.

Description

Technical Field

[0001] This utility model belongs to the field of black tea fermentation technology, specifically relating to a black tea fermentation device with a stirring function. Background Technology

[0002] Black tea is a fully fermented tea, made from suitable new tea buds and leaves through a series of processes including withering, rolling, fermentation, and drying. It gets its name from the reddish color of its brewed tea liquor and the color of its leaves after steeping.

[0003] In existing black tea fermentation devices, after the black tea is turned and fermented inside the fermentation box, broken leaves are easily produced. These broken leaves and twigs mixed in with the black tea can easily affect its quality. After the baffle is removed from the discharge port, the telescopic plate needs to be manually fixed to prevent it from interfering with the discharge of the black tea, which increases the workload of the staff. Utility Model Content

[0010] Preferably, the fixing assembly further includes a threaded cylinder and a heat insulation plate, with the threaded cylinder threadedly connected to the outer wall of the threaded column, and a heat insulation plate fixedly connected to one end of the threaded cylinder.

[0011] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model is equipped with a receiving component. When the black tea fermentation is complete and discharge is required, the two electric push rods on the moving plate are activated. The electric push rods drive the two moving plates to move in opposite directions along the moving groove. The movement of the moving plates causes the receiving box to move out of the fermentation box. The discharged black tea falls into the separation mesh frame. The residual branches and leaves mixed in with the black tea fall into the bottom wall of the receiving box through the holes on the separation mesh frame. Then the top frame moves up, moving it away from the support block. The movement of the top frame causes the separation mesh frame to move away from the receiving box. Then the black tea and residual branches and leaves in the separation mesh frame and the bottom wall of the receiving box are processed separately, which facilitates the separation and collection of black tea and residual branches and leaves mixed in with the black tea, and ensures the quality of the collected black tea.

[0012] 2. This utility model is equipped with a fixing component. When it is necessary to release the limiting mechanism from the turning and discharging mechanism, first hold the heat insulation plate to drive the threaded cylinder to rotate away from the threaded column. The operator holds the heat insulation ring and moves it upward. The upward movement of the heat insulation ring drives the pull rope to move upward along the through hole. The upward movement of the pull rope drives the components of the limiting mechanism to move upward away from the turning and discharging mechanism. After the heat insulation ring moves to the position of the threaded column, put the heat insulation ring on the threaded column. Then hold the heat insulation plate to drive the threaded cylinder to rotate and screw it onto the threaded column. The threaded cylinder and heat insulation plate can be used to limit the heat insulation ring, thereby limiting and fixing the limiting mechanism. This makes it convenient to fix the limiting mechanism and avoids the limiting mechanism from affecting the discharging operation of the black tea. Attached Figure Description

[0015] 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. Example 1

[0016] Please see Figure 1-6 The present invention provides the following technical solution: a black tea fermentation device with a stirring function, including a fermentation box 2, a stirring and discharging mechanism 4 is provided inside the fermentation box 2, a limiting mechanism 5 is provided on both sides of the fermentation box 2 and at the position corresponding to the stirring and discharging mechanism 4, a box cover 1 is provided on the top of the fermentation box 2, a receiving component 3 is provided on the bottom of the fermentation box 2, and a fixing component 6 is provided between the fermentation box 2 and the limiting mechanism 5.

[0017] Specifically, the receiving component 3 includes a receiving box 31, a moving part 32, and a separating mesh frame 33. The receiving box 31 is provided at both ends of the fermentation box 2. The moving part 32 is provided between the fermentation box 2 and the receiving box 31. The separating mesh frame 33 is provided inside the receiving box 31.

[0018] By adopting the above technical solution, after the black tea fermentation inside the fermentation box 2 is completed, the receiving boxes 31 at both ends of the fermentation box 2 are moved out of the fermentation box 2 by the moving part 32, and the limiting mechanism 5 releases the limiting effect on the stirring and discharging mechanism 4. Then, the stirring and discharging mechanism 4 is used to drive the black tea inside the fermentation box 2 to discharge. The discharged black tea falls into the separation mesh frame 33. The residual branches and leaves mixed in the black tea fall into the bottom wall of the receiving box 31 through the holes on the separation mesh frame 33, which facilitates the separation and collection of black tea and residual branches and leaves mixed in the black tea, and ensures the quality of the collected black tea.

[0019] Specifically, the movable component 32 includes a movable groove 321, a mounting plate 322, an electric push rod 323, and a movable plate 324. The movable groove 321 is provided at the bottom of the fermentation box 2. The mounting plate 322 is fixedly connected inside the movable groove 321. The electric push rod 323 is fixedly connected to both sides of the mounting plate 322. The movable plate 324 is fixedly connected to the output end of the electric push rod 323.

[0020] By adopting the above technical solution, the two electric push rods 323 on the moving plate 324 are activated. The operation of the electric push rods 323 drives the two moving plates 324 to move backward along the moving groove 321. The movement of the moving plates 324 drives the receiving box 31 to move out of the fermentation box 2, which facilitates the movement operation of the receiving box 31.

[0021] Specifically, the receiving assembly 3 also includes a support block 34 and a top frame 35. The top frame 35 is fixedly connected above the separating mesh frame 33, and the support block 34 is fixedly connected to both ends of the inner side wall of the receiving box 31 below the top frame 35.

[0022] By adopting the above technical solution, when it is necessary to process the debris and leaves on the bottom wall of the receiving box 31, the top frame 35 is moved upwards, moving it away from the support block 34. The movement of the top frame 35 causes the separation net frame 33 to move away from the receiving box 31, and then the debris and leaves on the bottom wall of the receiving box 31 can be processed, which is convenient for the staff to operate.

[0023] In this embodiment, the lid 1 is opened, and the black tea is placed into the fermentation chamber 2 for fermentation. During fermentation, the stirring and discharging mechanism 4 is used to stir the black tea to ensure the fermentation effect. When the black tea fermentation is complete and it needs to be discharged, the two electric push rods 323 on the moving plate 324 are activated. The electric push rods 323 drive the two moving plates 324 to move backward along the moving groove 321. The movement of the moving plates 324 causes the receiving box 31 to move out of the fermentation chamber 2. Then, the limiting mechanism 5 is released from its limiting effect on the stirring and discharging mechanism 4. The stirring and discharging mechanism 4 then drives the fermentation chamber 2 to continue fermentation. The black tea inside the fermentation box 2 is discharged. The discharged black tea falls into the separation mesh frame 33. The residual branches and leaves mixed in with the black tea fall into the bottom wall of the receiving box 31 through the gaps in the separation mesh frame 33. When it is necessary to process the collected black tea and residual branches and leaves, the top frame 35 is moved upward, so that it moves away from the support block 34. The movement of the top frame 35 causes the separation mesh frame 33 to move away from the receiving box 31. Then, the black tea and residual branches and leaves in the separation mesh frame 33 and the bottom wall of the receiving box 31 are processed separately, which facilitates the separation and collection of black tea and residual branches and leaves mixed in with the black tea, and ensures the quality of the collected black tea. Example 2

[0024] The difference between this embodiment and embodiment 1 is that the fixing component 6 includes a pull rope 61, a through hole 62, a heat insulation ring 63 and a threaded post 66. The pull rope 61 is fixedly connected to the side wall of the limiting mechanism 5. A through hole 62 is provided above the limiting mechanism 5 and at the position corresponding to the pull rope 61. One end of the pull rope 61 is fixedly connected to the heat insulation ring 63. The threaded post 66 is fixedly connected to the side wall of the fermentation box 2.

[0025] Specifically, the fixing component 6 also includes a threaded cylinder 64 and a heat insulation plate 65. The threaded cylinder 64 is threadedly connected to the outer wall of the threaded column 66, and the heat insulation plate 65 is fixedly connected to one end of the threaded cylinder 64.

[0026] By adopting the above technical solution, the heat insulation plate 65 is held to drive the threaded cylinder 64 to rotate away from the threaded post 66. Then, the heat insulation ring 63 is moved and fitted onto the outer periphery of the threaded post 66. Then, the heat insulation plate 65 is held to drive the threaded cylinder 64 to rotate and screw it onto the threaded post 66. The threaded cylinder 64 and the heat insulation plate 65 can be used to limit the position of the heat insulation ring 63, ensuring the stability of the fit between the heat insulation ring 63 and the threaded post 66.

[0027] In this embodiment, when it is necessary to release the limiting mechanism 5 from the mixing and discharging mechanism 4, first hold the heat insulation plate 65 to drive the threaded cylinder 64 to rotate away from the threaded column 66. The operator holds the heat insulation ring 63 and moves it upward. The upward movement of the heat insulation ring 63 drives the pull rope 61 to move upward along the through hole 62. The upward movement of the pull rope 61 drives the components of the limiting mechanism 5 to move upward away from the mixing and discharging mechanism 4, thereby releasing the limiting effect of the limiting mechanism 5 on the mixing and discharging mechanism 4. After the heat insulation ring 63 moves to the position of the threaded column 66, put the heat insulation ring 63 onto the threaded column 66. Then hold the heat insulation plate 65 to drive the threaded cylinder 64 to rotate and screw it onto the threaded column 66. The threaded cylinder 64 and the heat insulation plate 65 can be used to limit the heat insulation ring 63, thereby limiting and fixing the limiting mechanism 5. This makes it convenient to fix the limiting mechanism 5 and prevents the limiting mechanism 5 from affecting the discharging operation of the black tea.

[0028] The structure and principle of the mixing and discharging mechanism 4, which consists of a drive shaft, connecting rods, a push plate, a servo motor, a guide plate, a discharge port, and a baffle, have been disclosed in Chinese patent application number 202220643186.2, which describes a black tea fermentation device. Its working principle is as follows: Discharge ports are provided on both sides of the fermentation tank 2, and a baffle is slidably connected inside each discharge port. A drive shaft is rotatably connected inside the fermentation tank 2. A servo motor is fixedly connected to one end of the drive shaft on the side wall of the fermentation tank 2. A pair of connecting rods are fixedly connected to the drive shaft, and a push plate is fixedly connected to the end of each connecting rod away from the drive shaft. The outer side of the push plate contacts the side wall of fermentation box 2. Inside fermentation box 2, a guide plate is fixedly connected to both sides of the push plate. During fermentation, the output end of the servo motor drives the drive shaft to rotate back and forth. With the transmission of the connecting rod, the push plate can slide back and forth on the side wall of fermentation box 2, so that the push plate can stir the tea in fermentation box 2. After the black tea fermentation is completed, the baffle is removed from the inside of the discharge port. The output end of the servo motor drives the drive shaft to rotate back and forth. With the transmission of the connecting rod, the push plate can slide back and forth on the side wall of fermentation box 2. The push plate pushes the black tea inside fermentation box 2 through the discharge port for discharge.

[0029] The structure and principle of the limiting mechanism 5, which consists of a fixed frame, a telescopic plate, and a connecting spring, have been disclosed in a black tea fermentation device disclosed in Chinese patent application number 202220643186.2. Its working principle is as follows: the fixed frame is fixedly connected to the side wall of the fermentation box 2, and a telescopic plate is slidably connected inside the fixed frame. The lower end of the telescopic plate passes through the fixed frame, and a set of connecting springs is fixedly connected to the upper end of the telescopic plate. The upper ends of the connecting springs are fixedly connected to the inner side wall of the fixed frame. When in use, the pull plate is pulled upward to make the telescopic plate slide upward, thereby moving the telescopic plate away from the stirring and discharging mechanism 4.

[0030] The working principle and usage process of this utility model are as follows: The lid 1 is opened, and black tea is placed inside the fermentation chamber 2 for fermentation. During fermentation, the stirring and discharging mechanism 4 is used to stir the black tea to ensure effective fermentation. When the fermentation is complete and discharge is required, the two electric push rods 323 on the moving plate 324 are activated. The electric push rods 323 drive the two moving plates 324 to move backward along the moving groove 321. The movement of the moving plates 324 causes the receiving box 31 to move. When the fermentation tank 2 needs to be opened, and the limiting mechanism 5 needs to be released from its limiting effect on the turning and discharging mechanism 4, first, hold the heat insulation plate 65 to rotate the threaded cylinder 64 away from the threaded column 66. Then, the operator holds the heat insulation ring 63 and moves it upward. The upward movement of the heat insulation ring 63 moves the pull rope 61 upward along the through hole 62. The upward movement of the pull rope 61 moves the components of the limiting mechanism 5 upward away from the turning and discharging mechanism 4, thus releasing the limiting effect of the limiting mechanism 5 on the turning and discharging mechanism 4. After the heat insulation ring 63 moves to the position of the threaded column 66, The heat insulation ring 63 is fitted onto the threaded post 66. Then, by holding the heat insulation disc 65, the threaded cylinder 64 is rotated and screwed onto the threaded post 66. The threaded cylinder 64 and the heat insulation disc 65 can be used to limit the heat insulation ring 63, thereby limiting and fixing the limiting mechanism 5. This facilitates the fixing of the limiting mechanism 5 and prevents it from affecting the discharge of the black tea. Then, the stirring and discharging mechanism 4 is used to discharge the black tea inside the fermentation tank 2. The discharged black tea falls into the separating mesh frame 33. Inside, the broken branches and leaves mixed in with the black tea fall into the bottom wall of the receiving box 31 through the holes on the separating mesh frame 33. When it is necessary to process the collected black tea and broken branches and leaves, the top frame 35 is moved upward, moving it away from the support block 34. The movement of the top frame 35 causes the separating mesh frame 33 to move away from the receiving box 31. Then, the black tea and broken branches and leaves in the separating mesh frame 33 and the bottom wall of the receiving box 31 are processed separately, which facilitates the separation and collection of black tea and the broken branches and leaves mixed in with the black tea, and ensures the quality of the collected black tea.
