Description

Technical Field

[0001] The invention relates to the field of Liubao tea processing, in particular to autoclaving equipment for facilitating fermentation of Liubao tea and an autoclaving method for Liubao tea. Background Art

[0002] During the production process of Liubao tea, it needs to be withered at low temperature, which is a process of temperature changing from low-high-low. Usually, after the raw tea is produced, it needs to be refined and then aged before preservation. During this process, the Liubao tea leaves need to be steamed. Steaming requires moderate piling. The tea leaves are softened by steam to form loose tea. The purpose is to allow the tea leaves to ferment under the action of moisture and heat to improve the taste and soup color. Generally, water vapor is easily condensed during the steaming process, which leads to uneven moisture and heat in the steaming of Liubao tea.

[0003] In view of the technical problems existing in the above-mentioned autoclaving equipment for facilitating the fermentation of Liubao tea and the autoclaving method for Liubao tea, it was found through searching that there is a patent number CN201610078779.8 for an autoclaving method for Liubao tea, which relates to the technical field of tea processing. The method is to cool the steamed tea leaves to 55°C to 65°C after steaming, and then steam and press them for 10 to 15 hours. Compared with the prior art, the method solves the problem that high-temperature steaming and pressing easily causes heartburn of tea leaves because the steamed tea leaves are first cooled to 55°C to 65°C and then steamed and pressed. At the same time, the time required for cooling down after the steaming and pressing process is also shortened. Moreover, steaming and pressing after cooling down can also achieve the compacting effect of high-temperature steaming and pressing.

[0004] The steaming and pressing equipment for facilitating the fermentation of Liubao tea and the steaming and pressing method for Liubao tea, when in use, need to be steamed first and then cooled, and water vapor contacts the top cover during operation, and condensed water generated in the cooling process of the top cover condenses on the top cover, and drips into the tea leaves in the cooling process, resulting in different degrees of dryness and wetness of the tea leaves, which affects the later production of the tea leaves to a certain extent. At the same time, since the tea leaves are piled up too much in the process of steaming and cooling, it is difficult to discharge water vapor from the inside of the tea leaves under different environmental humidity conditions, resulting in the tea leaves being unable to leave the humidity environment in time, and it is difficult to cool the tea leaves in time and quickly, and it is also difficult to process the tea leaves inside the steaming and pressing equipment.

The diameter of the pressure cover 2 is larger than the pressure barrel 202. The pressure cover 2 and the steam box 1 are disassembled from bottom to top, and a ventilation groove is provided at the bottom of the pressure barrel 202.

[0043] The water collecting block 206 is located directly above the water storage barrel 203. The bottom of the water collecting block 206 is smoothly set, and the center point of the water collecting block 206 is tilted downward. The falling water bead 207 is rotatably set at the center point of the water collecting block 206. The falling water bead 207 is made of fast-cooling copper alloy.

[0044] There are two mounting frames 204, one mounting frame 204 is tilted downward at the right end inside the water storage barrel 203, and the other mounting frame 204 is tilted downward at the left end inside the water storage barrel 203. The water absorption plate 205 is separated from the mounting frame 204, and the water absorption plate 205 is made of highly absorbent resin material.

[0052] The top diameter of the air outlet ring 306 is smaller than the bottom diameter of the air outlet ring 306 , the diameter of the bottom plate 307 is equal to the inner diameter of the air outlet ring 306 , and the air outlet ring 306 is made of silicone material.

[0053] When the pressing cover 2 is put down, the tea barrel 302 is moved inside the placing rack 3, and the tea barrel 302 is placed in a position according to the length of the chain 304. When steaming tea, water vapor is steamed from the steam collecting barrel 301 through the bottom plate 307, and the steam is discharged from the air outlet ring 306, while the bottom plate 307 presses the tea leaves.
