Description

Technical Field

[0001] This utility model relates to the field of dark tea fermentation, specifically a dark tea oxygenation fermentation device. Background Technology

[0002] Jasmine black tea is a type of flower tea made primarily from jasmine flowers and black tea. It has many medicinal values. Jasmine is a common herb with a rich fragrance and abundant nutrients, offering various health benefits. Jasmine black tea combines the health benefits of black tea with the medicinal properties of jasmine, making it a healthy beverage that helps improve digestive function, offers some protection to the cardiovascular system, boosts immunity, refreshes the mind, and improves sleep quality.

[0003] The fermentation of dark tea involves breaking down the tea leaves, causing the chemical substances in the tea to oxidize with the air. Dark tea fermentation is mostly carried out by putting the tea leaves into a fermentation tank. Dark tea tends to pile up, and existing fermentation devices are not convenient for stirring the tea leaves, making it difficult for the bottom layer of the piled-up tea leaves to fully contact with oxygen, thus affecting the fermentation effect. Utility Model Content

[0004] To address the shortcomings of existing technologies, such as the tendency of dark tea to clump together and the inconvenience of stirring the tea in existing fermentation devices, which makes it difficult for the bottom layer of the clumped tea to fully contact with oxygen and affects the fermentation effect, this invention proposes an oxygen-entrained fermentation device for dark tea.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a black tea oxygenation fermentation device, including a base, a fermentation barrel fixedly connected to one side of the base, an installation platform fixedly connected to the surface of the fermentation barrel, a sealing door rotatably connected to one side of the fermentation barrel, and an oxygen supply mechanism provided in the inner cavity of the fermentation barrel.

[0006] The oxygen supply mechanism includes an oxygen supply pipe, the surface of which is rotatably connected to the inner cavity of the fermentation tank. A first oxygen supply pipe is fixedly connected to the surface of the oxygen supply pipe. There are multiple first oxygen supply pipes. The other end of each first oxygen supply pipe is fixedly connected to a second oxygen supply pipe. Oxygen outlet holes are opened on the surface of both the first and second oxygen supply pipes. There are several oxygen outlet holes. A filter screen is fixedly connected to the inner wall of each oxygen outlet hole.

[0007] Preferably, an oxygen generator is fixedly installed on one side of the mounting platform, and a connecting pipe is fixedly connected to the output end of the oxygen generator. A rotary joint is fixedly connected to the other end of the connecting pipe, and the surface of the rotary joint is connected to the inner cavity of the oxygen supply pipe.

[0008] Preferably, a mounting frame is fixedly connected to one side of the fermentation tank, a motor is fixedly installed in the inner cavity of the mounting frame, and a drive wheel is fixedly connected to the output end of the motor.

[0009] Preferably, a driven wheel is fixedly connected to the surface of the oxygen supply pipe, and a drive belt is drivingly connected to the surface of the driving wheel and the surface of the driven wheel.

[0010] Preferably, scrapers are fixedly connected to the surface of the second oxygenation pipe, and one side of each scraper is attached to the inner wall of the fermentation tank.

[0011] Preferably, a temperature sensor is fixedly installed on one side of the mounting platform, and a first probe is fixedly connected to the monitoring end of the temperature sensor. An oxygen content monitor is fixedly installed on one side of the mounting platform, and a second probe is fixedly connected to the monitoring end of the oxygen content monitor. The surfaces of the first probe and the second probe are both fixedly connected to the inner cavity of the mounting platform and extend into the inner cavity of the fermentation tank.

[0012] Preferably, an insulation sleeve is fixedly connected to the surface of the connecting pipe, and an electric heating wire is fixedly connected to the inner cavity of the insulation sleeve, with the electric heating wire sleeved on the surface of the connecting pipe.

[0013] The advantages of this utility model are:

[0014] This invention utilizes an internal compressor and other structures within an oxygen generator to supply oxygen to a connecting pipe. The connecting pipe connects to an oxygen supply pipe within the oxygen supply mechanism via a rotating joint, delivering oxygen to the hollow-structured oxygen supply pipe. The oxygen then flows through a first oxygen supply pipe to a corresponding second oxygen supply pipe, and finally exits through an oxygen outlet into the fermentation tank. The oxygen supply pipe can rotate along the inner cavity of the fermentation tank and the surface of the rotating joint. This rotation of the oxygen supply pipe simultaneously drives the first and second oxygen supply pipes to rotate. The rotating second oxygen supply pipe stirs the accumulated black tea raw materials in the fermentation tank, thereby improving the efficiency of contact between the black tea raw materials and oxygen. This solves the problems of black tea easily piling up, the inconvenience of stirring black tea in existing fermentation devices, and the difficulty for the bottom layer of accumulated black tea to fully contact oxygen, thus affecting the fermentation effect.

[0022] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0023] This application discloses an oxygen-fermentation device for dark tea. (Refer to...) Figures 1 to 3 A black tea oxygenation fermentation device includes a base 1, a fermentation barrel 2 fixedly connected to one side of the base 1, an installation platform 3 fixedly connected to the surface of the fermentation barrel 2, a sealing door 4 rotatably connected to one side of the fermentation barrel 2, and an oxygen supply mechanism 5 provided in the inner cavity of the fermentation barrel 2.

A first oxygen supply pipe 502 is fixedly connected to the surface of the oxygen supply pipe 501. There are multiple first oxygen supply pipes 502, and the other end of each first oxygen supply pipe 502 is fixedly connected to a second oxygen supply pipe 503. Oxygen outlet holes 504 are provided on the surfaces of both the first and second oxygen supply pipes 502 and 503. There are several oxygen outlet holes 504, and a filter screen 505 is fixedly connected to the inner wall of each oxygen outlet hole 504. An oxygen generator 6 is fixedly installed on one side of the mounting platform 3. A connecting pipe 7 is fixedly connected to the output end of the oxygen generator 6, and a rotating joint 8 is fixedly connected to the other end of the connecting pipe 7. The surface of the rotating joint 8 is connected to the inner cavity of the oxygen supply pipe 501. In this black tea oxygenation fermentation device, the base 1 plays a major supporting role. The fermentation tank 2 can be opened through the sealing door 4. The raw materials for fermenting black tea are placed in the fermentation tank 2, and the fermentation tank 2 is sealed by the sealing door 4. Oxygen is supplied to the connecting pipe 7 through the compressor inside the oxygen generator 6 and other structures. The connecting pipe 7 is connected to the oxygen supply pipe 501 in the oxygen supply mechanism 5 through the rotating joint 8, and the oxygen is delivered to the oxygen supply pipe 501, which has an internal cavity. The oxygen is then delivered to the corresponding second oxygen supply pipe 503 through the first oxygen supply pipe 502. Finally, the oxygen is discharged into the fermentation tank 2 through the oxygen outlet 504. The oxygen supply pipe 501 can rotate along the inner cavity of the fermentation tank 2 and the surface of the rotating joint 8. The rotation of the oxygen supply pipe 501 drives the first oxygen supply pipe 502 and the second oxygen supply pipe 503 to rotate. The rotating second oxygen supply pipe 503 can stir the black tea raw materials piled up in the fermentation tank 2, thereby improving the efficiency of contact between the black tea raw materials and oxygen.

A drive wheel 11 is fixedly connected to the output end of the motor 10. A driven wheel 12 is fixedly connected to the surface of the oxygen supply pipe 501. A transmission belt 13 is connected to the surface of the drive wheel 11 and the surface of the driven wheel 12. The motor 10 can be regarded as the power source of the oxygen supply mechanism 5. The motor 10 can first drive the drive wheel 11 to rotate. While the drive wheel 11 rotates, it drives the transmission belt 13 to rotate. While the transmission belt 13 rotates, it drives the driven wheel 12 and the oxygen supply pipe 501, which is fixedly connected to the driven wheel 12 on the same axis, to rotate automatically, thereby improving automation.

[0026] Reference Figure 3Each of the second oxygenation pipes 503 has a scraper 14 fixedly connected to its surface. One side of the scraper 14 is attached to the inner wall of the fermentation tank 2. Through the scraper 14, the oxygen supply pipe 501 drives the first oxygenation pipe 502 and the second oxygenation pipe 503 to rotate, while the scraper 14 scrapes along the inner wall of the fermentation tank 2. This can improve the turning efficiency of the black tea raw materials and avoid the black tea raw materials from adhering to the inner wall of the fermentation tank 2 and being difficult to remove.

An insulation sleeve 17 is fixedly connected to the surface of the connecting pipe 7. An electric heating wire 18 is fixedly connected to the inner cavity of the insulation sleeve 17. The electric heating wire 18 is sleeved on the surface of the connecting pipe 7. Through the temperature sensor 15 and the oxygen content monitor 16, the temperature sensor 15 and the oxygen content monitor... Instrument 16 monitors the temperature and oxygen content inside fermentation tank 2 through the first probe 1501 and the second probe 1601 respectively. When the oxygen content inside fermentation tank 2 is low, oxygen content monitor 16 detects and sends an electrical signal. The control system (such as PLC, controller, etc.) receives the electrical signal and activates oxygen generator 6. When the internal temperature of fermentation tank 2 is low, temperature sensor 15 detects and sends an electrical signal. The control system receives the electrical signal and activates heating wire 18. Heating wire 18 heats connecting pipe 7, and oxygen is injected into the interior of fermentation tank 2 through connecting pipe 7 with increased temperature. Heating oxygen can increase the kinetic energy of molecules, further improving the diffusion efficiency of oxygen inside fermentation tank 2.

[0028] Working principle: Opening the sealing door 4 allows the raw black tea material to be fermented to be placed into the fermentation tank 2. The sealing door 4 seals the fermentation tank 2. The temperature sensor 15 and the oxygen content monitor 16 monitor the temperature and oxygen content inside the fermentation tank 2 via the first probe 1501 and the second probe 1601, respectively. When the oxygen content inside the fermentation tank 2 is low, the oxygen content monitor 16 detects this and sends an electrical signal. The control system receives the electrical signal and activates the oxygen generator 6. The oxygen generator 6, through its internal compressor and other components, supplies oxygen to the connected... Oxygen is supplied through pipe 7. Pipe 7 is connected to the oxygen supply pipe 501 in the oxygen supply mechanism 5 via a rotating joint 8, and delivers oxygen to the oxygen supply pipe 501, which has an internal cavity. The oxygen is then delivered through the first oxygen supply pipe 502 to the corresponding second oxygen supply pipe 503. Finally, the oxygen is discharged into the fermentation tank 2 through the oxygen outlet 504. The motor 10 can be regarded as the power source of the oxygen supply mechanism 5. The motor 10 can first drive the drive wheel 11 to rotate. The rotation of the drive wheel 11 drives the transmission belt 13 to rotate. The rotation of the transmission belt 13 drives the driven wheel. The oxygen supply pipe 501, coaxially fixedly connected to the driven wheel 12, rotates automatically. The oxygen supply pipe 501 can rotate along the inner cavity of the fermentation tank 2 and the surface of the rotating joint 8. Simultaneously, the rotation of the oxygen supply pipe 501 drives the first oxygen supply pipe 502 and the second oxygen supply pipe 503 to rotate. The rotating second oxygen supply pipe 503 can stir the black tea raw materials accumulated in the fermentation tank 2, thereby improving the efficiency of contact between the black tea raw materials and oxygen. The rotation of the oxygen supply pipe 501, along with the rotation of the first oxygen supply pipe 502 and the second oxygen supply pipe 503, simultaneously drives the scraper 14 along... The inner wall of the fermentation tank 2 is scraped, which can improve the turning efficiency of the black tea raw materials and avoid the black tea raw materials adhering to the inner wall of the fermentation tank 2 and being difficult to remove. When the internal temperature of the fermentation tank 2 is low, the temperature sensor 15 detects and sends an electrical signal. The control system receives the electrical signal and activates the heating wire 18. The heating wire 18 heats the connecting pipe 7, and oxygen is injected into the interior of the fermentation tank 2 through the connecting pipe 7 with increased temperature. The oxygen heating can increase the kinetic energy of the molecules, further improving the diffusion efficiency of oxygen inside the fermentation tank 2.
