Description

Black tea fermentation device

Technical Field

The utility model relates to a dark tea processing technology field, concretely relates to dark tea fermenting installation.

Background

The black tea is named because the appearance of the finished tea is black. The black tea belongs to one of six major tea types, belongs to post-fermented tea, and has main production areas of Sichuan, Yunnan, Hubei, Hunan, Shaanxi, Anhui and the like. The traditional dark tea adopts a dark tea raw material with high maturity, is a main raw material for pressing compressed tea, and the dark tea making process generally comprises four procedures of de-enzyming, rolling, piling and drying.

The pile fermentation of the dark tea is the fermentation of the dark tea, in the pile fermentation process, the dark tea is usually paved on the ground in the prior art, and then workers hold a flexible water pipe to water the dark tea, so that the dark tea is fermented under certain temperature and humidity conditions. However, the watering amount is easily distributed unevenly in the mode, so that the tea fermentation degrees at different positions are different, and the overall quality of the tea is imaged.

Disclosure of Invention

An object of the utility model is to provide a can improve black tea fermenting installation of black tea quality.

In order to achieve the purpose of the invention, the technical scheme adopted by the utility model is as follows: a black tea fermentation device comprises support legs and a fermentation disc arranged on the support legs, wherein a vertical central rotating shaft is arranged in the center of the fermentation disc and is driven by a speed reducing motor fixedly arranged in the center of the bottom of the fermentation disc; a plurality of vertical stirring rotating shafts are uniformly arranged in the fermentation disc at the periphery of the central rotating shaft in an annular shape, and the lower ends of the stirring rotating shafts penetrate out of the fermentation disc and are in transmission connection with the central rotating shaft through a belt; the upper end of the central rotating shaft is provided with a transverse water conveying pipe, the center of the water conveying pipe is connected with the central rotating shaft, the bottom of the water conveying pipe is uniformly provided with a plurality of downward spray heads along the length direction, and the top of the center of the water conveying pipe is communicated with a water inlet hose through a rotary joint; the circumferential surface of the middle part of the stirring rotating shaft is uniformly provided with stirring rods extending along the radial direction of the stirring rotating shaft; electric heating pipes are arranged inside the side wall and the bottom surface of the fermentation plate, and the inner surface of the fermentation plate is provided with a uniform heating plate.

Preferably, the even hot plate is an aluminum alloy plate.

Preferably, a cable-stayed steel rope is arranged between the end part of the water pipe and the central rotating shaft, and two ends of the cable-stayed steel rope are fixedly connected with the water pipe and the central rotating shaft respectively.

The beneficial effects of the utility model are concentrated and are reflected in, can improve the degree of consistency that dark tea watered and heated at the pile fermentation in-process, make more even of dark tea fermentation. Particularly, the utility model discloses in the use, will need the even shop of raw materials of fermentation to fall in the fermentation dish. The gear motor starts, and the rotation of drive center pivot, the center pivot drives the raceway rotation at rotatory in-process, and water is evenly sprinkled on dark tea through inlet hose, rotary joint, raceway and shower nozzle in proper order. Meanwhile, the central rotating shaft drives the stirring rotating shaft to rotate through the belt, and then drives the stirring rod to stir the dark tea to a certain degree, so that the watering uniformity is further improved. Except watering, the utility model discloses still carry out certain heating to dark tea through electric heating pipe to accelerate fermentation speed, improve the quality of fermentation. The heat homogenizing plate can disperse the temperature in the fermenting tray homogeneously to avoid local overheat.

Drawings

Fig. 1 is a schematic structural view of the present invention;

fig. 2 is an enlarged view of a portion a in fig. 1.

Detailed Description

Combine a dark tea fermentation device that fig. 1 and 2 show, including landing leg 1 and the fermentation dish 2 of setting on landing leg 1, the center of fermentation dish 2 sets up vertical central pivot 3, central pivot 3 is driven by the gear motor 4 of fixed setting in the center of fermentation dish 2 bottom. Be the annular and evenly be provided with many vertical stirring pivot 5 in 3 outlying fermentation dishes 2 of central pivot, usually stirring pivot 5 sets up 4 around central pivot 3, the lower extreme of stirring pivot 5 is worn out fermentation dish 2 and is connected through the transmission of belt 6 with central pivot 3.

The upper end of the central rotating shaft 3 is provided with a transverse water conveying pipe 7, the center of the water conveying pipe 7 is connected with the central rotating shaft 3, the bottom of the water conveying pipe 7 is evenly provided with a plurality of downward spray heads 8 along the length direction, and the top of the center of the water conveying pipe 7 is communicated with a water inlet hose 10 through a rotary joint 9. The diameter of the fermentation plate 2 is generally larger due to the larger quantity of the primary pile fermentation of the dark tea, and the water conveying pipe 7 is required to have a larger length. Because only the middle of the water pipe 7 is connected with the central rotating shaft 3, in order to improve the stability of the water pipe, a diagonal steel cable 14 is preferably arranged between the end part of the water pipe 7 and the central rotating shaft 3, and two ends of the diagonal steel cable 14 are fixedly connected with the water pipe 7 and the central rotating shaft 3 respectively.
