Description

Technical Field

[0001] The invention relates to the technical field of tea fermentation, and in particular to a tea processing fermentation tank and a process. Background Art

[0002] The tea fermentation process refers to the process of making tea by controlling biological oxidation and other methods to make a series of chemical changes in tea, thereby forming the unique qualities of different types of tea; and tea fermentation equipment is equipment used in the tea fermentation process, which can provide suitable environmental conditions for tea fermentation, help control the fermentation process, and improve tea quality and production efficiency.

[0003] Most tea fermentation equipment is composed of temperature control devices, humidity control devices, ventilation devices, stirring devices, and control systems, so that the fermentation equipment can provide a variety of fermentation environments to meet the fermentation needs of different teas such as black tea and dark tea.

[0004] A tea fermentation processing device is disclosed in a patent application with publication number CN117751995A. When hinged plate No. 1 rotates with the tank body, the blocking plate will squeeze hinged plate No. 1. Hinge plate No. 1 is squeezed by the blocking plate and remains stationary. After hinged plate No. 1 is squeezed, hinged plate No. 1 rotates counterclockwise. When the tank body rotates, hinged plate No. 1 is driven by the tank body to move. Hinge plate No. 1 is driven by the tank body to cross the blocking plate. At this time, the torsion spring on hinged plate No. 1 is elastically reset, hinged plate No. 1 rotates clockwise, and hinged plate No. 1 pushes the tea leaves inside. When hinged plate No. 1 is reset, it pushes the tea leaves to disperse the tea leaves, thereby further avoiding the problem of tea leaves sticking together due to the reaction of polyphenol oxidase with tea polyphenols in the tea leaves during tea fermentation.

[0005] The prior art has the following defects:

[0006] During the tea fermentation process, the tea leaves need to be stirred so that they can fully contact with oxygen and enhance the oxidation reaction. However, in order to improve efficiency, more tea leaves are processed at a time, so a large amount of tea leaves are piled up. Even if stirred, a large amount of tea leaves still cannot fully contact with oxygen, resulting in slow or insufficient fermentation of the tea leaves, affecting processing efficiency and tea quality.

[0007] During the tea fermentation process, leaf residue and juice will remain in the fermentation equipment. In order to avoid contamination and odor transfer, the equipment needs to be cleaned frequently. However, the cleaning process of the fermentation equipment is complicated and time-consuming. Therefore, when the same type of tea is processed continuously, the cleaning cycle of the fermentation equipment is often delayed, which will affect the quality of the tea. At the same time, the stirring equipment has a complex structure and is located inside the equipment. Some tea leaves are easily attached during the stirring process and are not easy to be found. These residual tea leaves will seriously affect the quality of subsequent tea fermentation. Summary of the invention

[0008] In view of the problems in the prior art that tea leaves are not fully fermented due to pile-up and are inconvenient to clean up with tea leaves remaining, a tea processing fermentation tank and process are proposed.

[0009] The present application provides a tea processing fermentation tank and process, the purpose of which is to allow the tea leaves to fully contact with oxygen for fermentation and to make cleaning work more convenient.

[0017] Furthermore, the stirring member comprises a stirring rod fixedly mounted on the outside of the rotating rod, and a stirring block arranged on the outside of the stirring rod. The stirring block is installed at an angle, and the inclination directions are symmetrical in two ways.

[0018] Furthermore, a sealing component is arranged on the outside of the mounting plate, and the sealing component includes a receiving groove arranged on the upper and lower sides of the mounting plate, an assembly pipe arranged inside the receiving groove, an external plug pipe and an external air pipe arranged outside the assembly pipe, a piston pipe arranged inside the external plug pipe, a sealing gasket arranged at one end of the piston pipe away from the assembly pipe, and a collecting air pipe arranged outside the external air pipe;

[0028] Beneficial effects of the present invention:

[0029] 1. By setting up multiple placement components, the tea leaves are divided into multiple placement components during processing, so that the tea leaves are dispersed so that there will be no large amount of accumulation of tea leaves. The distance from the center to the surface is shorter, so it is easier to be fully stirred and can be fully contacted with oxygen for fermentation, which is beneficial to improving the quality of the tea leaves. At the same time, the stirring component is installed in the installation plate. In this way, after the fermentation is completed, the installation plate can be removed from the fermentation tank body by simply rotating the extension rod and the installation rod, which is convenient for observing and cleaning the stirring component.

[0030] 2. By setting up a support beam, the connection area can be supported and strengthened to make the main body of the fermentation tank more stable. At the same time, the mounting base is installed above the support beam, so that the overall weight of the auxiliary installation assembly is transferred to the part of the fermentation tank with the strongest load-bearing capacity, thereby avoiding deformation of the fermentation tank under the weight of the auxiliary installation assembly.

[0031] 3. By setting up the stirring component, when stirring is needed, all the rotating rods are connected, and the stirring parts rotate synchronously, so that all the tea leaves can be fully stirred. After fermentation is completed, all the rotating rods are separated, which is convenient for disassembly and assembly of the placement components and the installation plate, making the equipment more convenient to use.

[0032] 4. By setting up the sealing component, when the installation disk is rotated into the fermentation tank body, the sealing component is started, and the piston tube pushes the sealing gasket out of the storage groove, so that the sealing gasket contacts the inner wall of the installation port, and the gap between the installation disk and the inner wall of the installation port is sealed to avoid air leakage in the fermentation tank body, thereby providing a good and stable environment for tea fermentation.

[0060] By setting the sealing component 6, when the mounting disk 32 is rotated into the fermentation tank body 2, the sealing component 6 is started, and the piston tube 64 pushes the sealing gasket 65 out of the receiving groove 61, so that the sealing gasket 65 contacts the inner wall of the mounting port 31, and the gap between the mounting disk 32 and the inner wall of the mounting port 31 is sealed, thereby avoiding air leakage in the fermentation tank body 2 and providing a good and stable environment for tea fermentation.

[0061] Embodiment 3 is the third embodiment of the present invention, which provides: a tea processing and fermentation process, comprising the following steps:

[0062] Step 1: Prepare the materials, pick fresh tea leaves, and choose tea leaves with complete leaves and no pests or diseases;

[0063] Step 2: Killing the green tea leaves, using methods such as frying, steaming, baking and sun drying to terminate the enzymatic oxidation reaction of the tea leaves;

[0064] Step 3: Rolling: rolling the tea leaves to destroy the tea cell structure and promote tea fermentation;

[0065] Step 4: Fill the rolled tea leaves into the fermentation tray in the fermentation tank in layers, and the filling amount of the tea leaves shall not exceed 90% of the volume of the fermentation tray. The temperature, humidity and ventilation conditions of the fermentation tank shall be controlled, and the tea leaves shall be stirred intermittently during the fermentation process.

Figure 3 , then put your hand into the installation opening 31, hold the grasping groove 52 and pull the serving tray 51 upward, so that the serving tray 51 is separated from the holder 4 and enters the installation opening 31. When the part of the serving tray 51 pulled out of the installation opening 31 reaches one-half, hold both sides of the serving tray 51 with both hands respectively, completely remove the serving tray 51, and then fill the pre-treated tea leaves into the serving tray 51.

[0069] The tray 51 filled with tea leaves is placed at the installation opening 31 and pushed into the fermentation tank body 2 until the tray 51 is completely inserted and falls on the holder 4. After all trays 51 are filled with tea leaves, the deflection motor is started to make the extension rod 34 and the installation rod 35 drive the installation tray 32 to rotate, so that the installation tray 32 enters the installation opening 31. Figure 1 As shown, the air blowing device is then started, and the air blowing device fills the air into the external plug tube 63 through the collecting air pipe 67 and the external air pipe 66.

The rod 77 moves down into the hexagonal groove at the top of the next layer of connecting rod 75, and pushes the connecting rod 75 down, so that the telescopic rod 710, the rotating rod 72, the connecting rod 75, and the auxiliary rod 77 are connected in series, and the drive motor 79 is started, and the telescopic rod 710, the rotating rod 72, the connecting rod 75, and the auxiliary rod 77 rotate accordingly. When the rotating rod 72 moves down, the stirring member 73 leaves the mounting plate 32 and enters the serving plate 51, and the rotating rod 72 rotates, driving the stirring member 73 to rotate in the serving plate 51 to stir the tea leaves.

[0071] After fermentation is completed, start the aeration device to extract the air in the assembly tube 62, so that the sealing gasket 65 is retracted into the receiving groove 61, and then the adjustment rod 712 is lifted up, and the adjustment rod 712 is rotated by the knob so that the knob fits tightly against the outer wall of the mounting platform 78, and the deflection motor is started, the mounting plate 32 is moved out of the mounting port 31, the tea leaves are taken out, and the stirring member 73 is cleaned.
