Description
Technical Field
The invention relates to a tea processing machine, in particular to a drum-type enzyme deactivating machine.
Background
The fresh leaves of the raw dark green tea are relatively coarse and old compared with fresh green tea leaves, and comprise green tea stems, flower tea stems and even partial red tea stems. Therefore, the raw dark tea prepared by the traditional iron pan light-removing is black and bright, has tea fragrance overflowing, but has low production efficiency and high labor intensity. With the development of tea processing machineries, a drum-type fixation machine appears later, and the drum-type fixation machine has the biggest characteristics of high production efficiency and low labor intensity, thereby being widely popularized. However, when the drum-type green removing machine removes fresh dark green tea leaves with tea stalks, the fresh black green tea leaves are supported into a shed frame shape by the tea stalks, and the tea leaves at the center of the shed frame can not contact with the wall of a pot when the drum-type green removing machine rolls, so that the phenomenon of half-grown tea leaves occurs, the dark green tea leaves generate 10-15% of red-yellow slices, and the produced dark green tea has grey green color and luster, is mixed with the red-yellow slices, is bitter in taste, heavy in green smell and taste, and has quality far inferior to that of the traditional iron pot green removing tea. In order to eliminate the defects of the dark green tea produced by a drum-type green removing machine when people prepare dark green tea products, a color selection process is adopted to remove red and yellow pieces, and processes such as steaming hot fermentation, rolling again, pile-fermentation cold fermentation, drying again and the like are adopted to improve the color and taste of the dark green tea, so that the production cost is greatly increased, and the ideal tea quality is difficult to achieve. In order to completely kill fresh leaves with stems, a method of increasing the water-removing temperature, reducing the leaf feeding amount and prolonging the water-removing time is adopted, so that the problems of increased energy consumption, scorched leaves and reduced production efficiency are caused.
For example, the technique disclosed in "category of tea fixation machine and its performance (right in love, institute of tea research of academy of agricultural sciences, chinese tea, special review, 2006.4, P13"): for example, the machine-hour yield of the 6CS70 type roller fixation machine can reach about 300kg (fresh leaves), and the roller fixation machine has the defect that if the operation is improper, the phenomenon of leaf scorching is often generated.
Also, as disclosed in "characteristics of tea water-removing machine and tea-making quality (xiao dong shang zhou and guang xi gui lin tea research institute, guang xi agro-academy, P22, 2006): the roller type water-removing machine has a common defect that the water-removing machine is difficult to master and is easy to generate astringent taste, the water-removing time of the water-removed leaves in the roller is different, the water-removing time is half a minute for a short time and 6 minutes for a long time, the water-removing time is short, the water-removing speed is high, the water-removing time is less than 3 minutes according to tests, and the astringent taste of the finished tea is aggravated accordingly.
Therefore, the existing roller type water-removing machine has two opposite phenomena of water-removing impermeability and leaf burning, because fresh black raw tea leaves with tea stalks cannot be used for absorbing heat from the inner wall and the outer wall of a tea ball, the water-removing is not uniform, a large amount of red and yellow leaves are generated, in order to reduce the red and yellow leaves, the temperature of the cylinder wall can be only increased, the fresh leaf input is reduced, the water-removing time is prolonged, the water-removing energy consumption is increased, the water-removing efficiency is reduced, the scorched leaves phenomenon is more serious, the water-removing is not uniform, the red and yellow leaves are more, and the problem of heavy green and astringent taste still exists. The water-removing quality is far lower than that of the traditional manual frying pan, and the problem that the existing roller type water-removing machine cannot solve is solved.
Disclosure of Invention
The invention aims to overcome the defects of the prior art and discloses a drum-type de-enzyming machine for steam-assisted de-enzyming, which can thoroughly de-enzyme fresh dark green tea leaves and keep the tea leaves to have thick fried fragrance, wherein the prepared dark green tea leaves have no red and yellow slices, are black and bright, have consistent color and luster, do not need color selection in the subsequent process, and obviously improve the de-enzyming efficiency.
