Technical Field
[0001] This utility model relates to the field of sour tea kneading technology, and in particular to a sour tea kneading device. Background Technology
[0002] As a type of tea made through fermentation, the kneading and pressing process is crucial for sour tea. Kneading and pressing not only breaks down the cell walls of the tea leaves, promoting the release and transformation of their internal substances and laying the foundation for subsequent fermentation, but also shapes the tea leaves into a specific form.
[0003] During the kneading process, tea leaves release a large amount of tea juice containing organic acids. In existing kneading equipment, the kneading parts that come into direct contact with the tea leaves are usually made of metal. Even if stainless steel is used, the surfaces of these key components will still corrode, pit, or wear under long-term acidic, humid conditions accompanied by high-intensity physical friction. This not only shortens the overall service life of the equipment and increases the maintenance and replacement costs for enterprises, but also affects the final quality of the tea due to metal corrosion. In addition, because kneading produces a large amount of juice, the sealing performance of the bottom outlet or other structural joints of existing equipment is often not ideal, which can lead to leakage of acidic tea juice. This results in the loss of effective ingredients and contaminates the equipment and production workshop, making cleaning work inconvenient.
[0004] Therefore, this utility model proposes a tea kneading and pressing device to overcome the shortcomings of the prior art. Utility Model Content
[0005] In view of the problems existing in the art of kneading and pressing equipment for sour tea, such as the key components being easily corroded by acidic substances, short service life, and poor equipment sealing leading to juice leakage during the kneading and pressing process, this utility model aims to provide a sour tea kneading and pressing equipment with an improved structure that can effectively solve the above problems.

[0007] The protective sleeve has a sealing strip on its side wall, and the inner bottom of the kneading tank has a groove for the sealing strip to be embedded in. The discharge mechanism includes a cover plate for sealing the bottom opening of the kneading tank. The outer peripheral wall of the cover plate has a sealing ring, and the inner bottom of the kneading tank has a sealing groove for the sealing ring to be embedded in.
[0008] Furthermore, the mounting plate is detachably fixed to the bottom of the kneading tank by a bolt, the protective sleeve is fitted onto the outer wall of the fixing strip, the sealing strip of the protective sleeve is tightly fitted with the groove of the kneading tank, and the cover plate is detachably fixed to the bottom of the kneading tank by a locking assembly consisting of a connecting column, a connecting plate, a threaded sleeve and a bolt, and the sealing ring of the cover plate is tightly fitted with the sealing groove of the kneading tank, thereby forming a double sealing structure.
[0009] Preferably, the plurality of mounting plates are evenly distributed in a ring array at the bottom of the kneading tank.
[0010] Preferably, the protective sleeve is an integrally formed hollow cylindrical structure.
[0011] Preferably, the protective mechanism consists of the mounting plate, the bolt, the fixing strip, the protective sleeve, and the sealing strip.

[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model. Example
[0021] Please refer to Figure 1 and Figure 2 A kneading and pressing device for sour tea includes a kneading and pressing tank 1 as a container, and a protective mechanism 3 and a discharging mechanism 4 integrated at the bottom of the kneading and pressing tank 1. The mounting base of the protective mechanism 3 is composed of multiple mounting plates 31, which are distributed in a circular array and detachably fixed to the bottom outer wall of the kneading and pressing tank 1 by bolts 32. Each mounting plate 31 has a fixing strip 33 extending upward from its top, which serves as the working base for subsequent kneading and pressing actions. The discharging mechanism 4 is located at the central opening at the bottom inner side of the kneading and pressing tank 1. The discharge mechanism 4 mainly includes a cover plate 2 for sealing the central opening. The cover plate 2 is detachably fixed to the bottom of the kneading tank 1 through a connecting assembly consisting of a connecting column 42 and a connecting plate 43. When the cover plate 2 is closed, it seals the bottom of the kneading tank 1. When the cover plate 2 is open, it allows the kneaded tea leaves to be discharged from the central opening. Overall, the protective mechanism 3 surrounds the discharge mechanism 4. Together, they constitute the bottom functional assembly of the kneading tank 1, providing a complete working platform for the kneading, sealing, and discharge of the sour tea.
[0022] Please refer to Figure 3The protective sleeve 34 is specifically a hollow cylindrical structure. It is detachably installed on the outer wall of the fixing strip 33 by sleeve installation. Sealing strips 35 are integrally formed on both the left and right side walls of the protective sleeve 34. In the assembled state, the sealing strips 35 tightly penetrate and fill the groove 36 opened at the bottom inner side of the kneading tank 1. Through the physical wrapping of the fixing strip 33 by the protective sleeve 34, corrosion protection is achieved for the fixing strip 33. Simultaneously, the tight fit between the sealing strip 35 and the groove 36 forms the first layer of sealing structure. Please refer to... Figure 4 To further enhance the sealing performance, a sealing ring 47 is provided on the outer peripheral wall of the cover plate 2 of the discharge mechanism 4, and a ring-shaped sealing groove 46 is correspondingly opened on the inner bottom of the kneading tank 1. When the cover plate 2 blocks the central opening at the bottom of the kneading tank 1, the sealing ring 47 of the cover plate 2 is completely embedded in the interior of the sealing groove 46, forming a second sealing structure. This double sealing design, which is composed of the sealing strip 35 of the protective sleeve 34 and the sealing ring 47 of the cover plate 2, ensures that acidic juice cannot leak from the bottom of the equipment during the kneading process.
[0023] In a preferred embodiment, to facilitate the kneading of tea leaves, a kneading strip 41 is integrally formed on the top surface of the cover plate 2 facing the inside of the kneading tank 1. The kneading strip 41 can be designed as multiple strips arranged radially. The kneading strip 41 is used to apply kneading action to the tea leaves in the central area at the bottom of the kneading tank 1 during the kneading process, improving the uniformity of processing. Furthermore, the specific locking structure of the discharge mechanism 4 is achieved through the cooperation of the connecting column 42, the connecting plate 43, the threaded sleeve 44, and the bolt 45. The connecting plate 43 is fixedly connected to the cover plate 2 as a single unit via the connecting column 42, and the threaded sleeve 44 is fixedly connected to the bottom of the kneading tank 1 by welding. On the outer wall of the part, the shank of bolt 45 passes through the through hole opened on the connecting plate 43 in sequence, and then is threadedly connected to the threaded sleeve 44. By tightening bolt 45, the connecting plate 43 and the cover plate 2 connected thereto can be pulled upward as a whole, so that the sealing ring 47 is forcefully pressed into the sealing groove 46 to form a reliable locking and sealing. As a specific structural form, the protective sleeve 34 is a hollow cylindrical structure that matches the shape of the fixing strip 33, which facilitates quick installation and disassembly replacement. In order to obtain a uniform and stable support effect, multiple mounting plates 31 are fixedly connected at equal intervals in a ring array along the bottom circumference of the kneading tank 1.
[0024] Working principle: When the sour tea needs to be kneaded, the protective mechanism 3 is installed, and the tops of multiple mounting plates 31 are installed at the bottom of the kneading tank 1. The mounting plates 31 are evenly installed by using a circular array distribution. By tightening multiple bolts 32, the mounting plates 31 are stably fixed to the bottom of the kneading tank 1. The fixing strips 33 at the top of the mounting plates 31 are fixed. Then, the protective sleeve 34 is put on the outer wall of the fixing strips 33. The sealing strips 35 on the left and right sides of the protective sleeve 34 penetrate the grooves 36 at the bottom of the inner side of the kneading tank 1 to achieve a seal and create a relatively sealed environment for the kneading process. When kneading tea leaves, ensure that the cover plate 2 of the discharge mechanism 4 is closed. The kneading strip 41 on the top of the cover plate 2 can knead the sour tea in the middle section of the bottom inside the kneading tank 1. The sealing ring 47 on the outer wall of the cover plate 2 is embedded in the sealing groove 46 at the bottom inside the kneading tank 1 to enhance the sealing performance. Put the tea leaves to be kneaded into the kneading tank 1. The cover plate 2 prevents the tea leaves from falling into the space below. The grinding disc grinds the tea leaves in the kneading can 1 on top of the fixed strip 33. During this process, the protective sleeve 34, which is fitted on the outer wall of the fixed strip 33, effectively prevents the fixed strip 33 from being corroded and damaged, ensuring the service life of the fixed strip 33. If the protective sleeve 34 is worn, it is easy to replace it due to its installation method. When the kneading is complete and the material needs to be discharged, open the discharge mechanism 4 and rotate the two bolts 45 to make them rotate out of the threaded sleeve 44. As the bolts 45 rotate and disengage, they drive the connecting plate 43 to move, thereby causing the connecting column 42 and the cover plate 2 to disengage from the inner bottom of the kneading tank 1. The sealing ring 47 on the outer wall of the cover plate 2 also disengages from the inside of the sealing groove 46. The kneaded tea can be discharged from the opening at the inner bottom of the kneading tank 1, completing the discharge operation of the sour tea.
