[0031] The middle position of the inner side of the shell 501 is fixedly provided with an upper air distribution plate 503, a plurality of large holes are uniformly arranged on the upper air distribution plate 503, the upper air distribution plate 503 directly below the air inlet pipe 502 is not provided with a large hole, the bottom end of the inner side of the shell 501 is fixedly provided with a lower air distribution plate 504, a plurality of small holes are uniformly arranged on the lower air distribution plate 504, and the number of the small holes on the lower air distribution plate 504 is much larger than that of the large holes on the upper air distribution plate 503.

[0032] The shell 501 and the air inlet pipe 502 are fixedly provided with a transversely arranged convex plate 505, and the convex plate 505 communicates the shell 501 and the air inlet pipe 502. When hot air flows into the convex plate 505 through the air inlet pipe 502, the flow space on both sides of the hot air flow is increased, so that the hot air flow is uniformly distributed transversely first, and then flows into the space between the upper air distribution plate 503 and the lower air distribution plate 504 through the large holes of the upper air distribution plate 503.

[0033] Air adjusting openings 506 are arranged on both sides of the upper air distribution plate 503 and directly below both ends of the convex plate 505, the convex plate 505 on the upper end of the air adjusting opening 506 is threadedly connected with an adjusting rod 507, the position of the adjusting rod 507 on the convex plate 505 can be adjusted up and down, and the bottom end of the adjusting rod 507 is fixedly provided with a closing piece 508 for closing the air adjusting opening 506.

[0034] The working principle of the embodiment one of the present application is as follows:

[0035] Please refer to Figures 1-5In the working process, the hot air flows from the air inlet pipe 502 to the upper air distribution plate 503, and then flows to the two sides of the convex plate 505, so that the hot air is distributed horizontally. At the same time, the hot air is uniformly distributed to the space between the upper air distribution plate 503 and the lower air distribution plate 504 through the large holes of the upper air distribution plate 503. At this time, the hot air is uniformly sprayed to the tea in the lower end strip slot 301 through the small holes of the lower air distribution plate 504. The hot air is distributed horizontally through the convex plate 505, and then is uniformly distributed to the space between the upper air distribution plate 503 and the lower air distribution plate 504 through the large holes of the upper air distribution plate 503. Finally, the hot air is uniformly sprayed through the small holes of the lower air distribution plate 504, so as to achieve the purpose of uniform distribution of the hot air, and the tea in the strip slot 301 can be uniformly killed.

[0036] Please refer to Figures 1-5 When there is a temperature difference between the tea in the strip slots 301 on both sides of the strip plate 3, the adjusting rod 507 on the side with lower temperature is twisted to make the adjusting rod 507 drive the closing piece 508 to move upwards. The closing piece 508 that moves upwards no longer blocks the air adjusting port 506, and a part of the hot air at the upper end of the upper air distribution plate 503 flows to the space between the upper air distribution plate 503 and the lower air distribution plate 504 on the side, so that the hot air between the upper air distribution plate 503 and the lower air distribution plate 504 on the side with lower temperature is sufficient. The sufficient hot air between the upper air distribution plate 503 and the lower air distribution plate 504 is sprayed to the tea in the strip slot 301 on the side with lower temperature through the small holes of the lower air distribution plate 504, so as to increase the amount of hot air on the side with lower temperature, balance the temperature of the tea in the strip slots 301 on both sides, and make the tea in the same straight line have the same effect of killing green tea.

[0037] Example Two

[0038] Example Two is further improved on the basis of Example One.

[0039] Different from Example One, please refer to Figure 1 , Figure 5 , Figure 6 , Figure 7 and Figure 8 The air baffle 304 is fixedly installed outside the bracket on both sides of the strip plate 3. The top end of the air baffle 304 is close to the bottom end of the lower air distribution plate 504. The air baffle 304 can be elastically deformed. The circulation hole 305 is formed in the air baffle 304. One end of the circulation hole 305 is located at the upper end face of the air baffle 304, and the other end of the circulation hole 305 is located at the side face of the air baffle 304 and faces the space between the lower air distribution plate 504 and the strip plate 3.

[0040] The power rods 306 are fixedly connected between the wind baffles 304 on both sides, and the top end of the power rod 306 is provided with a tooth, and the top end of the power rod 306 is close to the bottom end of the lower air distribution plate 504; two groups of mounting blocks are fixedly installed on the upper end of the lower air distribution plate 504, the two groups of mounting blocks are between the two air adjusting openings 506 on the upper air distribution plate 503, and the two groups of mounting blocks are close to the air adjusting openings 506; support rods are movably sleeved in the two groups of mounting blocks respectively, one end of the partition plate 509 is fixedly sleeved on the support rod, and the other end of the partition plate 509 faces the two sides of the lower air distribution plate 504 respectively; the end, where the partition plate 509 is connected with the support rod, is provided with a tooth, and the tooth on the partition plate 509 penetrates through the upper air distribution plate 503 and is engaged with the tooth on the upper end of the power rod 306.

[0041] The ventilation pipes 510 are fixedly connected to one side of the strip arranging plate 3 close to the feeding end, the ventilation pipes 510 are communicated with the space between the upper air distribution plate 503 and the lower air distribution plate 504, the other end of the ventilation pipe 510 is fixedly connected with a transversely arranged blowing pipe 511, the bottom end of the blowing pipe 511 is provided with a blowing port 512 obliquely between the hot air cover 5 and the strip arranging plate 3, and the blowing port 512 is at an angle of 45° with the strip arranging plate 3. After the tea leaves pass through the feeding groove 302 and enter the strip arranging groove 301, the tea leaves in the strip arranging groove 301 slowly move to the fixation zone, and when the tea leaves are about to enter the fixation zone, the hot air flow blown out of the blowing port 512 blows the tea leaves to quickly enter the fixation zone, so that the tea leaves at the edge of the fixation zone are prevented from being heated by the outflowing hot air flow, cannot reach the fixation temperature in a short time, and the fixation effect is affected.

[0042] The heat insulation plates 513 are fixedly installed at both ends of the strip arranging plate 3, and the width of the heat insulation plate 513 is the same as the width of the shell 501.

[0045] Please refer to Figures 1-7When the temperature of the two sides of the striping plate 3 is different, the left and right movement of the striping plate 3 drives the wind baffle 304 and the power rod 306 to move, the teeth on the power rod 306 push the teeth at the bottom end of the partition plate 509 to make the partition plate 509 rotate, when the temperature on the left side is lower and needs to be adjusted, in the process of moving the wind baffle 304 and the power rod 306 to the left by the striping plate 3, the partition plate 509 on the left side rotates clockwise, so that the partition plate 509 on the left side divides the space between the upper air baffle 503 and the lower air baffle 504, the hot air flow flowing from the left power rod 306 is stored on the left side of the partition plate 509, and the hot air flow is sprayed from the small holes on the left side of the lower air baffle 504 to the tea leaves on the left side with lower temperature, so as to increase the effect of temperature adjustment on the left side, prevent the hot air flow flowing from the air adjusting port 506 to the space between the upper air baffle 503 and the lower air baffle 504 from flowing to other positions, and make the temperatures of the two sides reach balance faster.

[0046] Please refer to Figures 1-7 When the tea enters the striping groove 301 through the feeding groove 302 during the feeding operation, the tea in the striping groove 301 slowly moves to the fixation zone, when the tea is about to enter the fixation zone, the tea at the lower end of the blowing pipe 511 is quickly blown into the lower end of the lower air baffle 504 by the hot air flow blown from the blowing port 512, so that the tea quickly enters the fixation zone, prevents the tea from being in the position close to the fixation zone for a long time, causes the tea to not reach high temperature within the specified time, affects the fixation effect, and the hot air flow can be discharged only after passing through the heat preservation plate 513, prolongs the operation time of the hot air flow, increases the utilization efficiency of the hot air flow, and enhances the fixation effect of the tea.
