Problems solved by technology

[0004] Since the heating source directly heats the outside of the drum, there is a large energy consumption, a large temperature gradient inside the drum, and uneven heating of green leaves, which may easily cause burnt leaves, burst points, imperviousness, and killing of some green leaves due to excessive temperature. Uncooked and other phenomena seriously affect the quality of finishing

Embodiment 1

[0023] Embodiment 1: the mixed thermal energy tea greening machine that prevents scorched leaf of present embodiment 1, as figure 1 and figure 2 As shown, it includes a frame 1, a drum 2 placed on the frame, an outer cover 3, a transmission device, a heating device 4 and a controller. The inner wall of the drum is designed with a plurality of right-handed spiral guide vanes 22. The above-mentioned heating device includes a plurality of gas heating plates 41 located below the drum and distributed along the axis of the drum. The plurality of gas heating plates are equipped with independent gas proportional valves and Corresponding to the igniter, the gas proportional valve is externally connected to the gas storage tank through the gas pipeline, and multiple gas hot plates are distributed along the central axis of the drum to form multiple heating blocks, and the multiple heating blocks heat the outer surface of the drum in sections, among which There are four heating areas al...

Embodiment 2

[0025] Embodiment 2: the mixed thermal energy tea greening machine that prevents scorched leaf of present embodiment 2, as image 3 As shown, a rotary damper plate 7 is also designed on the end plate of the hot air pipe. The above-mentioned rotary damper plate is designed with adjustment holes corresponding to the ventilation holes on the end face, and an adjustment rod 71 is fixed on the rotary damper plate. The axis of the adjusting rod coincides with the central axis of the above-mentioned hot air pipe. The adjusting rod passes through the above-mentioned horizontal hot air pipe and extends out of the drum. The operator can drive the rotation of the rotary damper plate through the adjusting rod according to the requirements of the finishing process, and then control the damper plate. The overlapping degree of the upper adjustment hole and the ventilation hole of the end plate adjusts the air volume and wind pressure of the end face of the hot air pipe accordingly, and a dial...

Embodiment 3

[0026] Embodiment 3: the mixed thermal energy tea greening machine that prevents scorched leaf of present embodiment 3, as Figure 4As shown, the end side pipe wall and the bottom pipe wall of the hot air pipe are also designed with a pull-out damper plate 8 respectively. Corresponding to the adjustment hole, a control rod 81 is fixed on the pull-out damper plate. The axis of the control rod is parallel to the axis of the above-mentioned hot air pipe. The control rod is close to the wall of the hot air pipe and extends to the outside of the drum. Pull the pull-out damper plate through the control rod, and then control the overlapping degree of the adjustment hole on the damper plate and the ventilation hole on the pipe wall, and adjust the air volume and air pressure of the side wall and bottom pipe wall of the hot air pipe accordingly. Scale lines can also be set on the wall, which can accurately display the pulling distance of the damper plate. The other parts of this embodi...

Abstract

The invention discloses a mixed heat energy tea leaf fixation machine capable of preventing leaves from being burnt. The mixed heat energy tea leaf fixation machine comprises a rack, a roller, an outer cover, a transmission device, a heating device and a controller, wherein a plurality of spiral leaf guide plates are arranged on the inner wall of the roller; the heating device comprises a fuel gashot plate which is located at the bottom of the roller and is distributed along the axis of the roller; the outer cover is used for sealing the roller; a heating interlayer is formed between the outer cover and the roller; an air inducing pipe communicating with the heating interlayer is arranged at the top of the outer cover; and the other end of the air inducing pipe is arranged at a feeding hole of the roller and extends into an inner cavity of the roller. According to the mixed heat energy tea leaf fixation machine, a double-heating manner is adopted and high-temperature fuel gas waste gas in the interlayer is guided into the inner cavity of the roller through a draught fan and the air inducing pipe to heat the inner cavity of the roller, so that the temperature and the uniformity ofthe inner cavity of the roller are improved, the fixation speed and the fixation temperature are improved, and the temperature difference between the inner part and the outer part of the roller is reduced; green leaves in the roller are uniformly heated and a leaf burning and point bursting phenomenon is not easy to occur; and meanwhile, energy sources are also saved and the utilization cost is reduced.

Description

technical field [0001] The invention relates to the technical field of tea processing, in particular to a mixed heat tea greening machine capable of preventing scorched leaves and green color, killing thoroughly and ripening. Background technique [0002] Fixing is a very important process in tea processing. Its main purpose is to destroy and passivate the oxidase activity in fresh leaves by high temperature, inhibit the enzymatic oxidation of tea polyphenols in fresh leaves, and prevent tea from drying during drying. At the same time, the green smell of the green leaves can be quickly emitted during the greening process, which promotes the formation of the tea's own good tea aroma. The main methods of greening are frying, steaming, soaking and radiation. [0003] Drum-type de-enzyming is generally the main type of de-enzyming on the market. Electric heating or gas is used as the heating source to heat and conduct the outer surface of the drum. The operation is stable, the s...
