Description

Technical Field

[0001] The utility model belongs to the technical field of tea production, and particularly relates to a tea fermentation tank. Background Technique

[0002] There are very obvious differences in taste between fermented tea and non-fermented tea. The taste of fermented tea is very thick, the taste is mellow, and the color of the tea soup after brewing is very dark, with the aroma of rosin or chestnut and other aromas; the taste of non-fermented tea is relatively refreshing, the color is very green, and the tea soup after brewing only has the natural aroma of tea leaves; there are also certain differences in the efficacy between fermented tea and non-fermented tea. The nature of fermented tea is very mild. During the fermentation process, the activity of tea polyphenols can be reduced, and the irritation to the stomach will be weakened. After brewing and drinking, it can play a role in nourishing and protecting the stomach; the content of tea polyphenols in non-fermented tea is very high, and it has obvious irritation to the stomach, but it has a good anti-inflammatory and bactericidal effect and can inhibit the activity of various viruses in the human body.

[0003] The fermentation of tea requires the tea tree buds and leaves to go through initial processing procedures such as withering, rolling, fermentation, and drying to make rough tea, and then refined. This process is more like a series of enzymatic reactions, which is actually a process of contacting with oxygen, that is, through biological oxidation in the tea. After the cell wall inside the tea is damaged, the oxidase enzymes existing in the cell wall promote a series of oxidation processes of catechins. In the cells of the tea, catechins exist in the cell sap, while oxidase mainly exists in the cell wall. Therefore, it is necessary to damage the cell wall. Therefore, it is necessary to damage the cell wall to carry out tea fermentation, which also explains the reason why fermented tea needs to be rolled.

[0004] The ways of kneading fresh tea are generally divided into two types: mechanical and manual. Manual kneading is mainly done by rubbing with both hands, with low efficiency. Mechanical kneading mainly uses mechanical equipment to knead the tea leaves. And for the fermentation tank, it is necessary for workers to put the kneaded tea leaves into the tank and stir-fry them to increase the contact surface between the tea leaves and the air, so as to increase the contact surface between the tea leaves and the oxygen in the air. The overall steps are relatively cumbersome and inconvenient during the processing and fermentation of tea.

[0005] In view of the problems in the related art, no effective solution has been proposed yet. Content of the Utility Model

One side of the rod body of the fixed rod is connected with a scraper, and the other side of the rod body of the fixed rod is connected with a kneading pendulum. A swinging mechanism is arranged at one end of the fixed rod, and a driving mechanism is arranged at one end of the tank body.

The controller 16 is electrically connected to the silicone rubber heating pad 14 through a relay. The middle of the fixed rod 3 is a rectangular structure, and the two ends are cylindrical structures. In this embodiment, a kneading pendulum 5 is arranged in the tank body 1, and the tea leaves are kneaded by the back and forth swing of the kneading pendulum 5; at the same time, the rotation of the tank body 1 is utilized to drive the tea leaves to be turned with the help of the turning rod 9, so as to increase the contact area of ​​the tea leaves with oxygen and improve the fermentation efficiency. The overall equipment integrates kneading, turning and fermentation functions, which improves the fermentation efficiency of the fermented tea while reducing manual labor and improving the production efficiency of the fermented tea.

[0021] In order to reduce the weight of the kneading pendulum 5 and facilitate the rising of the kneading pendulum 5 to prevent the kneading pendulum 5 from forming a movement obstacle when the tank body 1 rotates, in the present embodiment, as a preferred technical scheme of the utility model, the kneading pendulum 5 is a hollow structure, and the two sides of the top are slidingly connected to the two sides of the scraper 4, and an electric lifting rod 10 is arranged inside the kneading pendulum 5, and the output end of the electric lifting rod 10 is connected to the inside of the kneading pendulum 5, and the rod body of the electric lifting rod 10 is fixed on the fixed rod 3.

[0022] In order to prevent the tank body 1 and the scraper 4 from hard contact and facilitate the scraping of the material on the inner wall of the tank body 1, in this embodiment, as a preferred technical solution of the utility model, a silicone sleeve 11 is fixed on the outer side of the edge of the scraper 4.

[0023] In order to facilitate the extraction of the fermented raw materials from the tank body 1 , in this embodiment, as a preferred technical solution of the utility model, a discharge port 12 is provided on one side of the tank body 1 , and a sliding door 13 is provided at the discharge port 12 .

[0024] In this embodiment, the swing mechanism 6 and the driving mechanism 7 are known technologies. The driving mechanism 7 can drive the tank body 1 to rotate via a motor, a belt and pulley mechanism, or a gear transmission, etc. The swing mechanism 6 and the driving mechanism 7 can be selected according to the working conditions and are not limited here.

[0025] In summary, with the above technical solution of the present utility model, fresh tea leaves are put into the interior of the tank body 1 from the discharge port 12, and the sliding door 13 is closed. Then, the kneading pendulum 5 is lowered by the electric lifting rod 10 to make it contact the tea leaves. The swinging mechanism 6 is used to drive the fixed rod 3 to swing back and forth, so that the kneading pendulum 5 kneads and breaks the tea leaves by using the kneading grinding surface 8, causing the cell walls of the tea leaves to be damaged. During this process, the kneading pendulum 5 can be lowered to compress the distance between the tea leaves and the kneading pendulum 5, thereby adjusting the kneading strength. After the kneading is completed, the kneading pendulum 5 is raised by the electric lifting rod 10, and the tank body 1 is rotated. The tea leaves on the inner wall of the tank body 1 are scraped off by the scraping plate 4. Then, through the continuous rotation of the tank body 1, the tea leaves are continuously turned by the turning rod 9, increasing the contact surface with oxygen, thereby improving the fermentation efficiency. It should be noted that since the silica gel sleeve 11 of the scraping rod 4 contacts the interior of the tank body 1, when the tank body 1 rotates, the silica gel sleeve 11 will contact the turning rod 9. Due to the soft characteristics of the silica gel sleeve 11, it can directly pass over the turning rod 9 without causing movement interference. The silicone rubber heating pad 14 has the characteristics of small thickness, being not easily damaged after kneading, and being convenient for efficient temperature control. During this process, the temperature and humidity inside the tank body 1 are monitored by the temperature and humidity sensor 15. When the temperature and humidity exceed or are lower than the threshold value, the detection information is converted into an electrical signal by the temperature and humidity sensor 15 and output to the controller 16. The temperature of the silicone rubber heating pad 14 is controlled by the controller 16 through a relay, and the humidity inside the tank body 1 is controlled by the controller 16 to control the water pump connected to the sprayer 17.

[0026] Finally, it should be noted that in the present utility model, unless otherwise clearly defined and limited, terms such as "installation", "setting", "connection", "fixation", "swivel connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or integrated; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the internal communication of two components or the interaction relationship between two components. Unless otherwise clearly defined, for those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0027] The above are only the preferred embodiments of the present utility model and are not used to limit the present utility model.
