[0053] The plurality of arc-shaped guide plates 12 are driven to slide into the placing cylinder 1 along the corresponding sliding grooves 13 by the sliding assembly, so that the tea leaves in the flying process are guided along the arc-shaped guide surface of the arc-shaped guide plate 12 to approach and contact the heating arc piece 7 in the first arc-shaped groove 6 for heat conduction, improving the heating and killing efficiency of the tea leaves.

[0057] As a further embodiment of the application, the flow guide assembly comprises:

[0058] A plurality of single-pass pipes 14 are arranged on the outer side of the placing cylinder 1 in a circumferential direction, and a plurality of flow guide pipes 15 are fixedly connected to the single-pass pipes 14, one end of the plurality of flow guide pipes 15 is fixedly connected to the placing cylinder 1 and is tangent to the inner side of the placing cylinder 1;

[0067] The piston shaft of the swing hydraulic cylinder 29 rotates to drive the circular disc 25 to rotate in the circular shell 24, so that the two ends of the through hole 26 are respectively separated from the exhaust end of the air pump 16 and one end of the second communication pipe 20, and one end of the two L-shaped through holes 28 is respectively communicated with the exhaust end of the air pump 16 and one end of the second communication pipe 20 with the rotation of the circular disc 25, and the other end of the two L-shaped through holes 28 is respectively communicated with the two external pipes 27 (as shown in Figure 9 In the initial stage of temperature reduction and flow guide, the high-temperature gas in the annular cavity is discharged from the exhaust end of the air pump 16 and directly discharged from one of the external pipes 27 along the corresponding L-shaped through hole 28, and as the high-temperature gas is discharged, a negative pressure is generated in the placing cylinder 1, so that external air is sucked into the other external pipe 27 and into the placing cylinder 1, and the opening directions of the two external pipes 27 are opposite, so that the discharge position of the high-temperature gas and the adsorption position of the external air are far away from each other, preventing the backflow of the high-temperature gas;

[0089] The plurality of arc-shaped guide plates 12 are driven to slide into the placing cylinder 1 along the corresponding sliding grooves 13 by the action of the sliding assembly, so that the tea leaves in the flying process are guided along the arc-shaped guide surface of the arc-shaped guide plate 12 to approach and contact the heating arc piece 7 in the first arc-shaped groove 6 for heat conduction, thereby improving the heating and killing efficiency of the tea leaves, the airflow heated by the heating arc piece 7 is both a heat transfer medium and a power source, and the tea leaves are guided by the arc-shaped guide plate 12 to directly contact the heating arc piece 7 in the flying process, so that the tea leaves are dispersed and heated in the flying process, thereby reducing the physical damage caused by mechanical stirring and improving the integrity of the tea leaves.

This is prior art and will not be described in detail here.

[0092] The heat enters the heat dissipation cavity between the refrigeration arc piece 9 and the second arc-shaped groove 8 in the conversion process, and after the installation roller 5 rotates 180 degrees, the heat dissipation cavity formed between the refrigeration arc piece 9 and the second arc-shaped groove 8 is communicated with the corresponding heat dissipation groove 11 on the sealing cover plate 10, so that the heat is continuously dissipated outward along the heat dissipation groove 11, the refrigeration arc piece 9 continuously carries out heat exchange refrigeration, the tea leaves continue to fly through the flow guide assembly after being heated and killed, and the refrigeration effect of the refrigeration arc piece 9 is used to quickly cool the air, so that the tea leaves are cooled through air exchange after being killed, and the tea leaves are directly cooled through the guiding action of the arc-shaped guide plate 12 and the refrigeration arc piece 9, the cooling speed of the tea leaves after being killed is effectively improved, the enzyme reaction is quickly terminated, and the humid heat generated by the accumulation of the tea leaves is prevented through the guided flight of the cooling air, so that the killing effect is stable, and the color and taste of the tea leaves after being killed are guaranteed.
