Description

Technical Field

[0001] The present application relates to the technical field of tea fermentation, and in particular to a Pu'er ripe tea fermentation device. Background Art

[0002] Pu'er tea, as a traditional famous tea in China, enjoys a high reputation in the domestic and foreign tea markets for its unique fermentation process and profound cultural heritage. In the production process of Pu'er ripe tea, fermentation is a crucial link, which determines the taste, aroma and subsequent aging quality of the tea. Therefore, the technological innovation and optimization of Pu'er ripe tea fermentation equipment is of great significance to improving the quality of tea and ensuring production efficiency. The fermentation technology of Pu'er ripe tea mainly goes through natural fermentation and artificial pile fermentation. The natural fermentation process is slow and difficult to control, while artificial pile fermentation is regulated by human through fermentation equipment, so that the tea can achieve the ideal taste and aroma in a short time.

[0003] The existing technology still has the following problems:

[0004] 1. It is difficult for the existing ripe tea fermentation equipment to turn the tea leaves, resulting in uneven heating, moisture and contact with nutrients during the fermentation process. If the tea leaves are not turned, there may be temperature and humidity differences between the inside and outside, top and bottom of the tea pile, resulting in uneven fermentation degrees, reducing the quality and taste of the tea leaves. Manual turning requires a lot of manpower and time, and the turning is also uneven, resulting in large differences in the taste of the tea leaves. In addition, whether it is turned manually or by machine, it is difficult to turn the tea leaves that have settled at the bottom of the pile, thus affecting the quality of the ripe tea.

[0005] 2. When fermenting ripe tea, sacks are usually laid to ensure good air permeability, which can provide the necessary oxygen exchange for the tea and help the microbial fermentation and aging process inside the tea. However, the existing fermentation equipment lacks protection mechanisms for sacks. Without protection mechanisms, the tea pile may deform or collapse due to gravity, fermentation gases or human operation, causing the sacks to fall, resulting in a lack of a warm environment for the fermentation of ripe tea. In addition, the falling of sacks is difficult to be discovered in time, and a large amount of tea will be lost while waiting for the staff to discover it. Summary of the invention

When the tea leaves need to be turned over periodically, the motor 4 drives the rotating rod 5 to rotate, and the rotating rod 5 drives the first stirring mechanism 63 to squeeze the chassis 62. At this time, the chassis 62 slides on the inner wall of the fermentation barrel 61, so that the tea leaves shake above the chassis 62, that is, the tea leaves shake at the bottom of the fermentation barrel 61. At this time, the chassis 62 squeezes the buffer mechanism 64, and the buffer mechanism 64 restores the chassis 62 to its original position. At the same time, when the chassis 62 moves down, the second stirring mechanism 65 turns over the tea leaves in the inner cavity of the fermentation barrel 61, so that the equipment can turn over the tea leaves, ensuring that the tea leaves are evenly heated and moistened during the fermentation process, that is, after adding water regularly, the moisture on the outer surface of the tea leaves can be evenly distributed by turning over the tea leaves, ensuring that the fermentation process of the entire tea pile remains consistent.

When the rotating rod 5 rotates, it drives the stirring blade 631 to rotate. The rotation of the stirring blade 631 drives the pressure rod 632 to rotate. The rotation of the pressure rod 632 drives the pressure rod 632 to squeeze the protrusion 634. At this time, the protrusion 634 squeezes the chassis 62. The chassis 62 slides on the inner wall of the fermentation barrel 61. The chassis 62 squeezes the buffer plate 646. The buffer plate 646 is squeezed and drives the connecting bar 645 to rotate. The rotation of the connecting bar 645 drives the slide 644 to rotate on the first fixed The stirring blade 631 rotates and slides on the inner wall of the fermentation barrel 61, so that the tea leaves at the bottom of the fermentation barrel 61 are shaken and dispersed. At this time, the stirring blade 631 can stir the tea leaves, that is, turn the tea leaves over, to ensure that the tea leaves are evenly heated and moistened during fermentation, thereby improving the quality of the tea leaves.

The second spring 6584 is used to squeeze the pressure block 6585 so that the shielding ring 6586 can always shield the floating groove 67 to prevent the tea leaves and nutrients produced by fermentation from falling from the inner cavity of the floating groove 67. The connecting seat 6581 and the floating ball 657 are movably connected. The floating rod 6583 is located in the inner cavity of the floating groove 67, and the diameter of the floating groove 67 is larger than the diameter of the floating rod 6583, so that the floating rod 6583 can produce a small tilt within the inner cavity of the floating groove 67 when the connecting seat 6581 swings. The shielding ring 6586 is located on the upper surface of the floating groove 67. The diameter of the shielding ring 6586 is larger than that of the floating groove 67, and is used to shield the floating groove 67. When the shaking mechanism 658 swings as a whole, the elastic force of the second spring 6584 can squeeze the pressure block 6585, so that the pressure block 6585 can always fit the floating groove 67, and the second rack 655 is driven to move downward while the chassis 62 is pressed down. The downward movement of the second rack 655 drives the gear 656 to rotate on the fixed block 654. The rotation of the gear 656 drives the first rack 653 to move upward. The upward movement of the first rack 653 drives the connecting plate 652 to slide on the second fixed rod 651. At this time, the connecting plate 652 approaches the chassis 62. At the same time, the connecting plate 652 squeezes the shaking mechanism 658 when moving upward, that is, squeezes the floating rod 6583.Since the upper surface of the connecting plate 652 is tilted as a whole, the floating rod 6583 in contact with the connecting plate 652 is squeezed, causing the connecting seat 6581 to tilt. At this time, the connecting seat 6581 drives the connecting rod 6582 to swing, and the swing of the connecting rod 6582 drives the adjusting rod 6587 to swing, so that the shaking mechanism 658 turns over the tea leaves at the bottom of the fermentation barrel 61, and cooperates with the up and down shaking of the bottom plate 62 to break up the tea leaves. The tea leaves are broken up and deblocked, increasing the gap inside the tea pile, thereby improving the circulation of oxygen. At the same time, during the turning process, the tea leaves are easily damaged when they are gathered together, and the turning of the stirring leaves 631 realizes the uniform turning of the tea leaves from bottom to top, and the up and down shaking makes the tea leaves dispersed through the shaking mechanism 658 and the stirring leaves 631. The turning from top to bottom allows the nutrients in the fermentation barrel 61 to be more fully in contact with the microorganisms, thereby improving the utilization rate of the nutrients, promoting the fermentation process, avoiding excessive or low local nutrients that lead to abnormal fermentation, and improving the quality of the fermentation of cooked tea.

The sack serves as a protective barrier to reduce the contamination of the tea leaves by external bacteria, fungi and other microorganisms, so that the tea leaves remain relatively clean during fermentation. The sack is under the protective plate 72, and the ventilation holes 73 cooperate with the ventilation ports 2 for ventilation during fermentation, that is, when the fermentation component 6 turns the tea leaves, the volume of the tea leaves will increase. At this time, the extra sack can move in the inner cavity of the protective cover 71, and at the same time, the protective plate 72 squeezes the third spring 75 to make the first slide bar 74 slide in the inner cavity of the protective cover 71.

[0041] In summary, the interior of the outer barrel 1 is ventilated through the vent 2, and the operation of the motor 4 drives the rotating rod 5 to rotate, so that the tea leaves piled in the fermentation component 6 are turned over.

At this time, the bottom plate 62 squeezes the buffer mechanism 64, and the buffer mechanism 64 restores the bottom plate 62 to its original position. At the same time, when the bottom plate 62 moves down, the second stirring mechanism 63 The stirring mechanism 65 turns over the tea leaves in the inner cavity of the fermentation barrel 61, so that the equipment can turn over the tea leaves, ensuring that the tea leaves are evenly heated and moistened during the fermentation process, that is, after adding water regularly, the moisture on the outer surface of the tea leaves can be evenly distributed by turning over the tea leaves, ensuring that the fermentation process of the entire tea pile remains consistent. When protecting the fermented tea leaves, a sack is placed between the fermentation barrel 61 and the protective cover 71, and there is extra sack inside the protective cover 71. The sack is below the protective plate 72, and the ventilation holes 73 cooperate with the ventilation ports 2 for ventilation during fermentation, that is, when the fermentation component 6 turns over the tea leaves, the volume of the tea leaves will increase. At this time, the extra sack can be moved in the inner cavity of the protective cover 71, and at the same time, the protective plate 72 squeezes the third spring 75, so that the first slide bar 74 slides in the inner cavity of the protective cover 71. At this time, the protective plate 72 drives the slider 76 to slide in the inner cavity of the protective cover 71, which is convenient for increasing the space between the fermentation component 6 and the protective component 7, improving the fault tolerance of the fermentation component 6 to the turning of the tea leaves, and avoiding damage to the tea leaves during turning.
