Description

Technical Field

[0001] The invention relates to the field related to tea fermentation, and in particular to an automatic tea fermentation device. Background Art

[0002] Shaking and fermentation is an important step in the tea making process. The freshly picked tea leaves are first spread out to cool so that they lose some moisture and lower the temperature, laying a good foundation for fermentation. Then the edge cells of the tea leaves are slightly damaged by shaking them many times. The enzymes in the cells come into contact with the air, gradually forming partial oxidation, making the edges of the leaves appear red. Shaking and standing are carried out alternately, and the tea leaves will gradually release their natural fragrance and form the characteristics of "green leaves with red edges" during repeated fermentation. The degree of fermentation is judged by carefully observing the color, softness and aroma of the tea leaves. Once the ideal state is reached, the tea leaves are immediately fried to lock in the aroma and terminate the fermentation. During the shaking and fermentation process, the temperature, humidity, shaking times and intensity must be controlled accurately to make the finished tea have a balanced flavor and unique aroma.

[0003] A Pu'er tea shaking fermentation device with Chinese patent publication number CN217218042U includes a bottom plate, a first support plate is arranged on the bottom plate, a second support plate is arranged on the bottom plate on one side of the first support plate, a roller is rotatably arranged on the second support plate, a groove is arranged on the second support plate, a convex ring is arranged on one side of the roller, a connecting plate is arranged on one side of the roller, a motor is arranged on one side of the first support plate, the rotor shaft of the motor passes through the through hole arranged on the first support plate and is connected to the connecting plate, a vertical plate is arranged inside the roller, a feed port is arranged on the roller, slots are arranged on the roller on both sides of the feed port, plug plates are inserted in the slots, and a ventilation device is arranged on one side of the roller. The vertical plate in the roller can evenly turn over the accumulated tea leaves, the rubber sleeve on the vertical plate prevents the tea leaves from excessive friction, the through holes on the roller filter out the broken pieces generated by the tea leaves during the shaking process, and the tea leaves can be taken out more conveniently by removing the quick release rod and pushing the baffle to the right.

[0036] The specific implementation process is as follows:

[0037] When the tea leaves need to be shaken and fermented, firstly, the two sets of movable covers 2 on the top of the shaking barrel 1 are opened, and the tea leaves are poured into the shaking barrel 1. Then, the movable covers 2 are closed, and the first motor 7 is started to work. The first motor 7 drives the reducer 6 to rotate the rotating shaft 5, and the shaking barrel 1 rotates accordingly, and the tea leaves are shaken by a drum.

[0038] During the shaking process of the drum, the second motor 97 is started to work, and the second motor 97 drives the active pulley 962 to rotate, and the active pulley 962 can drive the driven pulley 964 to rotate through the synchronous belt 963, and the driven pulley 964 drives the rotating disk 965 to follow the rotation through the shaft, and the follower 967 can be toggled by the toggle column 966, and the follower 967 is toggled once to rotate ninety degrees, so that the middle part carries the support shaft 94 to make the fixed box 91 follow the angle adjustment, and the collecting trough 93 is placed directly under the shaking barrel 1 to collect the debris generated during the shaking process. After the shaking and collection are completed, a collecting bucket can be set in front of or behind the fixed box 91, and the driving of the adjusting component 96 is cooperated to realize the position adjustment of the collecting trough 93, so that the debris is poured into the collecting bucket;

[0039] When the tea leaves need to be left to ferment after shaking, the angle of the fixed box 91 needs to be adjusted through the adjustment component 96, so that the stratification mechanism 92 corresponds to the bottom of the shaking barrel 1, and then the four groups of cylinders 923 are started to work, and the push rods on the top of the cylinders 923 lift the stratification plate 921 through the electromagnet 922, so that it passes through the two groups of rubber sheets and enters the shaking barrel 1, and continues to enter to stratify the tea leaves in the barrel, and then the top of the stratification plate 921 can be adsorbed on the stable magnet 21 at the bottom of the movable cover 2 to complete the stratification of the tea leaves. If it is necessary to adjust the gap of the stratification plate 921, the third motor 9246 can be started to work, and the third motor 9246 drives the connecting shaft 9245 to rotate the gear 9243, and the gear 9243 can move the rack 9242, and the slide plate 9241 can move the cylinder 923 to adjust the position of the corresponding plate above it;

[0040] After the flat plate stratification is completed, the stratified tea leaves need to be spread evenly, the electromagnet 922 is turned off to release the adsorption of the stratified plate 921, and then the first motor 7 is started to rotate the shaking barrel 1 to evenly spread the stratified tea leaves;
