Embodiment 1

[0040] As shown in the figure, an energy-saving needle-bud tea frying machine includes a frame 21 , a shell 3 and a drum 4 . The shell 3 is fixedly arranged on the frame 21, and the drum 4 is arranged in rotation in the shell 3. The feeding end and the discharging end of the drum 4 are opened outside the shell 3, and a closed space is formed between the outer wall of the drum 4 and the shell 3.

[0041] The drum 4 is a cylinder body. The inner wall of the drum 4 is a corrugated structure 10 . Specifically, the wavy structure 10 may be formed by a series of wavy curves arranged on the inner wall of the drum 4 along the length direction of the drum 4 .

[0042]The feeding end and the discharging end of the drum 4 are provided with tires 5, the tires 5 at the feeding end of the drum 4 cooperate with the active positioning wheel support 9 arranged on the frame 21, the tires 5 at the discharging end of the drum 4 cooperate with the The driven wheel holder 6 on the frame 21 cooper...

Embodiment 2

[0047] The method for processing needle-bud-shaped green tea by using an energy-saving needle-bud-shaped tea frying machine comprises the following process steps:

[0048] 1) Spread the fresh leaves thinly to 1-2cm, and spread them at 24-30°C until the moisture content is 70%±1;

[0049] 2) Use a drum-type de-greening machine, a hot-air de-greening machine or a microwave de-greening machine to de-green the fresh tea leaves to a moisture content of 55-60%;

[0050] 3) Turn on the electric hot air stove 2, adjust the temperature of the hot air to 100-110°C, and blow it into the energy-saving needle bud-shaped tea frying machine;

[0051] 4) After the green leaves are cooled and softened, put the green leaves continuously into the energy-saving needle-bud tea frying machine from the green leaf input port 2, and pass the first fryer mounting seat according to the dryness and frying effect of the tea leaves after frying. 14 and the second stirrer mounting seat 15 adjust the height...

Embodiment 3

[0058] The method for processing needle-bud-shaped black tea using an energy-saving needle-bud-shaped tea frying machine comprises the following process steps:

[0059] 1) Thinly spread the fresh tea leaves to 1-2cm, and wither at 25-35°C until the moisture content is 60%±1;

[0060] 2) Put the withered leaves in step 1) into the rolling machine and knead for 90-120 minutes. The pressure process: air pressure for 5 minutes, light pressure, 15 minutes, medium pressure for 60-90 minutes, heavy pressure for 5 minutes, air pressure for 5 minutes;

[0061] 3) Ferment the rolled leaves of step 2) at 26-28°C and relative humidity of 92-97% for 3.5h-4h;

[0062] 4) Dry the fermented leaves in step 3) with a hot air dryer at 110-120°C to a moisture content of 35-40%;

[0063] 5) Cool the tea leaves obtained in 4) to below 35°C, then put them in a closed container and let them stand for 60-90 minutes;

[0064] 6) Turn on the electric hot air stove 2, adjust the hot air temperature to ...

Abstract

The invention discloses an energy-saving needle-shaped tea stir-frying machine and a method for processing needle-shaped tea by using the energy-saving needle-shaped tea stir-frying machine. Accordingto the energy-saving needle-shaped tea stir-frying machine, a roller is arranged, in rotating coordination, in a shell; a material inlet and a material outlet of the roller reveal outside the shell;a sealed space is formed between an outer wall of the roller and the shell; a stir-frying paddle rotating shaft is arranged in the roller; a set of stir-frying paddles are arranged on the stir-fryingpaddle rotating shaft; two ends of the stir-frying paddle rotating shaft are supported by a first stir-frying paddle mounting base and a second stir-frying paddle mounting base; the stir-frying paddlerotating shaft and the roller are both driven by a variable-speed gear motor, wherein rotation directions of the stir-frying paddle rotating shaft and the roller are opposite; a hot air pipe is arranged at a material inlet of the roller; a fixed leaf feeding port is arranged on the hot air pipe; the hot air pipe is connected with an electrically-heated blast furnace; a hot air recovery fan is arranged at a material outlet end of the roller; and a hot air recovery pipe is connected with the hot air recovery fan. Green tea stir-fried by using the energy-saving needle-shaped tea stir-frying machine is tight, straight and beautiful in strip shape, and very well preserves bright green color of green tea; and straight-strip-type Congou black tea stir-fried by using the energy-saving needle-shaped tea stir-frying machine is tight, straight and beautiful in strip shape, and has golden tea color.
