AI Technical Summary
Existing drum-type tea-fixing machines tend to scorch tea leaves during the heating process, resulting in uneven fixing and easily producing scorched edges. Furthermore, the leaf-turning rib structure is not thoroughly maintained.
The high-temperature hot air fixation machine is designed with a spiral auger and a uniform air distribution plate. Combined with the feed guide blades, spiral auger and heat dissipation guide blades, it uses high-temperature hot air to heat the tea leaves evenly and turns the tea leaves over by a turning plate to avoid contact between the tea leaves and the high-temperature inner wall. The uniform air distribution plate and heat dissipation guide blades are used to achieve uniform fixation and heat dissipation.
This process achieves uniform fixation of the tea leaves, avoids scorching the edges, improves the fixation effect and enhances the color and aroma of the tea, ensuring that the tea leaves remain emerald green and the brewed tea has a clear color.

[0005] To ensure that the tea in the spiral auger can be constantly turned and heated fixation, a group of material turning plates are arranged in the spiral auger.
[0006] Preferably, the pitch of the spiral auger is 25 cm, and the height is 15 cm.
[0007] To ensure uniform heating of tea, a uniform air distribution disc is arranged at the middle position of the spiral auger, the uniform air distribution disc is arranged concentrically with the fixation drum, and the diameter of the uniform air distribution disc is smaller than the inner diameter of the fixation drum.
[0008] To avoid scalding of tea by high temperature inner wall and cause scorched edges, the tea inlet and the hot air inlet are arranged at intervals, an air outlet pipe is arranged in the fixation drum and connected with the hot air inlet, and the air outlet of the air outlet pipe blows towards the tea falling from the tea inlet.
[0009] Further, the heat dissipation material outlet guide blade is a group of inclined guide ribs arranged obliquely along the length direction of the fixation drum.
[0010] The utility model discloses beneficial effect: the utility model discloses high hot air to tea and carries out fixation of green, thereby effectively solved the problem of the existing drum inner wall heating mode easy to cause the problem of the edge. The tea is in fixation of green cylinder first through spiral auger and is stifled, and this structure can kill the tea leaf, and through the material turning -on plate and is turned on, makes the fixation of green tea leaf more uniform. The tea leaf after killing enters the heat dissipation and is discharged and is guided blade, and the tea leaf is scattered in this position and carries out heat dissipation, and the water vapor is emitted, and the tea leaf keeps jade green, and the tea soup color that the tea leaf is brewed is clear. Meanwhile, through the utility model discloses fixation of green, can also improve the aroma of tea.
[0011] The utility model will carry out more detailed explanation in the following with the combination of drawing and example. DRAWINGS

[0017] Example, as Figs. 1 to 5 Shown, a high hot air fixation of green aroma machine, including fixation of green cylinder 1, fixation of green cylinder 1 one end is provided with tea inlet 2, and the other end is provided with tea outlet 3. Fixation of green cylinder 1 is horizontally arranged and rotates under the drive of driving mechanism. Fixation of green cylinder 1 is provided with hot air inlet 4 at one end of tea inlet 2, and tea inlet 2 is spaced apart from hot air inlet 4, and fixation of green cylinder 1 is provided with air outlet pipe 9 that is butt joint with hot air inlet 4, and the air outlet of air outlet pipe 9 blows tea leaf that falls from tea inlet 2, to avoid the tea leaf that falls to contact the high temperature inner wall of air outlet pipe 9 and cause the edge, when fixation of green, the temperature of hot air that hot air inlet 4 exports is 400-500 DEG C, and the tea leaf that falls from tea inlet 2 is blown to the drum inner wall by hot air.
[0018] The inner wall of fixation of green cylinder 1 is sequentially provided with material guide blade 5, spiral auger 6 and heat dissipation and discharge guide blade 7 from tea inlet 2 to tea outlet 3.
[0019] Material guide blade 5 is a group of circular arc blade structure, and the tea leaf is guided into spiral auger 6 and carries out fixation of green under material guide blade 5.
[0020] The pitch of the spiral auger 6 is 25 cm, and the height is 15 cm, so that the tea moves in the spiral auger 6 along the spiral auger 6 to the direction of the heat dissipation and discharge guide blade 7, and the tea is killed in the relatively closed environment in the spiral auger 6, so that the tea is killed thoroughly, the effect of the killing is improved, and the time of the killing is shortened. In order to turn out the tea at the bottom of the spiral auger 6 for killing, and to make the tea be killed uniformly, a group of turning plates 61 are arranged in the spiral auger 6 at intervals, and the turning plates 61 are transverse to the adjacent two auger blades. In order to make the hot air be able to hit the spiral auger 6, the middle position of the spiral auger 6 is provided with a uniform air disc 8, and the uniform air disc 8 is arranged concentrically with the killing drum 1, the diameter of the uniform air disc 8 is smaller than the inner diameter of the killing drum 1, and after the high-temperature air blows to the uniform air disc 8, the high-temperature air is scattered to the spiral auger 6 in all directions under the blockage of the uniform air disc 8 and is blown out through the gap between the uniform air disc 8 and the inner wall of the killing drum 1. The structure can also form a local high temperature at the front end of the uniform air disc 8, so as to facilitate the killing of the tea.
[0021] The heat dissipation and discharge guide blade 7 is a group of inclined guide ribs arranged obliquely along the length direction of the killing drum 1. After the tea is discharged from the spiral auger 6, the tea is scattered and cooled under the guidance of the heat dissipation and discharge guide blade 7, and moves to the discharge port, and the discharge is completed. The structure can timely dissipate the humid heat generated by the high-temperature killed tea, so that the tea keeps emerald green. Therefore, through the improvement of the killing drum, the tea can be killed thoroughly, the effect of the killing is improved, and the generation of the burnt edge is avoided, and the color and taste of the tea are improved.
