Description

Technical Field

[0001] The present invention relates to the field of tea fermentation equipment, and particularly relates to a tea fermentation machine for improving the fermentation quality of tea and a using method thereof. Background Art

[0002] Tea fermentation refers to the general term for teas with the "fermentation" process in tea production. After the tea tree buds and leaves are made into raw tea through primary processing procedures such as withering, rolling, fermentation, and drying, and then refined, the resulting tea is fermented tea, which can be divided into lightly fermented tea, semi-fermented tea, fully fermented tea, and post-fermented tea. Currently, fermentation machines are basically used for fermentation;

[0003] A tea fermentation machine with the application number 202122607972.5 includes two support plates. A stirring barrel is rotatably fitted above the two support plates. A feed inlet is formed on the circumferential side of the stirring barrel, and an arc-shaped sealing plate is slidably fitted. The arc-shaped sealing plate corresponds to the feed inlet. A plurality of through holes are formed inside both the stirring barrel and the arc-shaped sealing plate;

[0004] In the above-mentioned prior art, for the spreading of tea leaves, workers often use their hands to stir and spread the tea leaves evenly, which easily leads to uneven thickness or inconsistent thickness dimensions each time, resulting in an adverse impact on the fermentation quality.

When the two rope pulley lifting assemblies 8 tighten the pulling force on the fermentation pallet 11, the fermentation pallet 11 is in a straight plate shape. When the two rope pulley lifting assemblies 8 relax the pulling force on the fermentation pallet 11, the fermentation pallet 11 is bent downward in a V shape. On the outer side wall of the fermentation box 2, a telescopic bottom plate assembly 9 for supporting and limiting the bottom of the outer edge of the fermentation pallet 11 is provided.

An equidistant gap is formed between two adjacent blades 11a, and the width of the gap is 1 mm - 3 mm. A number of evenly distributed ventilation holes 11c are provided on each blade 11a. Through the above specific structural design, the wind generated by the ventilation pipe body structure 13 can pass through the gaps between the blades 11a and the ventilation holes 11c on the blades 11a to blow from the bottom to the top of the tea leaves, so as to accelerate the fermentation of the tea leaves. The blades 11a are made of bamboo strips or stainless steel strips.

The rotation of the output shaft of the motor 805 can drive the rotation of the rope winding shaft 802, so as to realize the tightening and loosening of the hanging rope 803 by controlling the rotation direction of the motor 805. In the relaxed state of the hanging rope 803, the fermentation support plate 11 drops vertically to both sides with the middle suspension rod structure 6 as the center, and in the tightened state of the hanging rope 803, the fermentation support plate 11 spreads out in a straight plate state with the middle suspension rod structure 6 as the center.

[0063] Working principle:

[0064] Pour a certain amount of weighed tea greens into the cloth hopper 1. The tea greens fall out from the lower opening of the cloth hopper 1 and land on the fermentation pallet 11 in the fermentation box 2. The push rod of the first electric telescopic rod 601 of the middle suspension rod structure 6 expands and contracts, thereby driving the first dredging sphere 603 to move up and down in the lower opening of the cloth hopper 1, thus realizing the dredging of the lower opening of the cloth hopper 1. The shaking drive assembly 5 drives the fermentation box 2 to shake in the horizontal direction, realizing the uniform distribution of the tea leaves in the fermentation box 2, so that the laying thickness of the tea leaves is consistent. The ventilation pipe structure 13 ventilates into the aggregate hopper 3, and the wind passes through the flexible connection pipe 4 and blows towards the fermentation pallet 11, accelerating the fermentation of the tea leaves. After fermentation is completed, the telescopic bottom plate assembly 9 releases the limitation on the lower side edge of the fermentation pallet 11, and the two rope wheel lifting assemblies 8 release the pulling of the fermentation pallet 11. The two sides of the fermentation pallet 11 droop downward in a V shape, and the tea leaves laid on the upper surface of the fermentation pallet 11 fall into the aggregate hopper 3 for collection. Then, the rope wheel lifting assembly 8 pulls and tightens the fermentation pallet 11 upward to realize the flat unfolding of the fermentation pallet 11. The push rod of the first electric telescopic rod 601 of the middle suspension rod structure 6 expands and contracts, thereby driving the second dredging sphere 604 to move up and down in the lower opening of the aggregate hopper 3, thus realizing the dredging of the lower opening of the cloth hopper 1.
