And starting the whole equipment to work. When the tea leaves are enzyme-deactivating, the fresh tea leaves are thrown into the enzyme-deactivating section 301 of the U-shaped groove pot group 3, the pot frame 2 and the U-shaped groove pot group 3 on the pot frame do reciprocating motion along the width direction of the rack 1, the third air blower 2001 and the electric heater 2002 respectively work, formed hot air enters the hot air box 4 through the first heat supply pipeline 6 and then enters the enzyme-deactivating section 301 of the U-shaped groove pot group 3 through the plurality of air nozzles 7, the tea leaves are enzyme-deactivated and heat supplied from the upper side, and moisture contained in the fresh tea leaves can be volatilized rapidly. Meanwhile, heat generated when fuel such as firewood or coal is combusted in the first combustion chamber 5 is transmitted to the green removing section 301 of the U-shaped groove pot group 3 through the heat conducting plate 11 and the heat conducting cavity in sequence, and tea leaves are subjected to green removing and heat supplying from the lower part.

Because the U-shaped groove pot group 3 inclines from the fixation section 301 to the strip tidying section 302, the tea leaves after fixation can naturally transit to the strip tidying section 302 under the action of the vibration force and the gravity generated when the U-shaped groove pot group 3 reciprocates.

When the tea leaves are arranged, the tea leaves enter the strip arranging section 302 of the U-shaped groove pot group 3, at the moment, the pot frame 2 and the U-shaped groove pot group 3 on the pot frame reciprocate along the width direction of the rack 1, heat generated when fuel such as firewood or coal is combusted in the second combustion chamber 9 is transmitted to the green removing section 302 of the U-shaped groove pot group 3 through the heat conducting plate 11 and the heat conducting chamber in sequence, and heat is supplied for tea leaf green removing from the lower part. Meanwhile, the flue gas generated by the fuel in the first combustion chamber 5 and the second combustion chamber 9 enters the smoke collection box 24 and is discharged out of the smoke discharge pipeline 25; in the process, cold air (having the same temperature as the external environment) blown by the fourth air blower 2704 enters the outer sleeve 2701 through the cold air inlet 2702, flows in an annular track, and performs primary heat exchange with waste heat dissipated by the outer wall of the smoke exhaust pipeline 25 and the plurality of radiating fins 26, hot air formed after heat exchange enters the heat collecting pipe 2705 through the hot air outlet 2703, transversely flows through the smoke collecting box 24 along the inside of the heat collecting pipe 2705, performs secondary heat exchange with smoke in the smoke collecting box 24, and hot air after heat exchange enters the hot air hood 8 through the second heat supply pipeline 10 and finally diffuses to the strip tidying section 302 of the U-shaped groove boiler group 3 to supply heat for tea strip tidying from the upper part.

In the process of enzyme deactivation and strip arrangement, the U-shaped groove pot group 3 is bent and deformed downwards at the middle part due to heating, and the heat insulation plates 12 with high two ends and low middle part just can form a reliable matching relation with the pot bottom, so that heat is further prevented from leaking.

In the process of water removing and strip tidying, the first temperature measuring element 13 and the second temperature measuring element 14 respectively and correspondingly detect the real-time temperature of the water removing section 301 and the strip tidying section 302, and send the detected temperature data to the controller 19, the controller 19 sends control instructions to the first relay 29, the first frequency converter 30, the second relay 31 and the second frequency converter 32 in real time according to the set upper limit temperature threshold and the set lower limit temperature threshold, so that the opening and closing of the first air blower 15 and the second air blower 16 are controlled in real time, the blowing amount of the first air blower 15 and the second air blower 16 is adjusted, and the oxygen content in the first combustion chamber 5 and the second combustion chamber 9 is controlled; in addition, control instructions are sent to the first electromagnetic valve 17 and the second electromagnetic valve 18 in real time to control the opening and closing of the corresponding air inlets, so that automatic and accurate temperature control is realized, and the temperatures of the water-removing section 301 and the strip tidying section 302 can be controlled within the error range of +/-10 ℃.

Taking the temperature control of tea fixation as an example, the method specifically comprises the following steps: the upper temperature threshold and the lower temperature threshold stored in the controller 19 are 350 ℃ and 250 ℃ respectively, which are required by tea fixation. The first temperature measuring element 13 detects the real-time temperature of the water-removing section 301, and sends the detected temperature data to the controller 19, when the real-time temperature value is lower than the set lower limit temperature threshold (250 ℃), the controller 19 sends a control instruction (level signal) to the first frequency converter 30, the first frequency converter 30 increases the motor rotating speed of the first air blower 15, so that the first air blower 15 runs at a high speed, the blast volume of the first air blower 15 is increased, the oxygen content in the first combustion chamber 5 is increased, the combustion is accelerated, and the temperature rise rate is accelerated; when the real-time temperature value reaches the set lower limit temperature threshold (250 ℃), the controller 19 sends a control instruction (level signal) to the first frequency converter 30, and the first frequency converter 30 properly reduces the motor rotation speed of the first air blower 15 compared with the previous rotation speed so that the first air blower runs at a low speed or a medium speed, and properly reduces the air blowing amount of the first air blower 15, thereby properly reducing the oxygen content in the first combustion chamber 5, properly slowing down combustion, and properly slowing down the temperature rise rate; when the real-time temperature value reaches the set upper limit temperature threshold (350 ℃), the controller 19 respectively sends control instructions (level signals) to the first electromagnetic valve 17 and the first relay 29, the first electromagnetic valve 17 is closed, the first relay 29 is disconnected, the corresponding air inlet is closed, and the first air blower 15 stops working. Therefore, automatic temperature control is realized, and the aim of saving resources is fulfilled.

It should be noted that, because the heat transfer process is from the heat conducting plate 11 to the enzyme deactivation section 301 through the heat conducting chamber, there is inevitable heat loss, and therefore, there is an error in temperature, but this embodiment can control the temperature error range within an error range of ± 10 ℃, and the accuracy is high.

The temperature control principle and process of the tea strip tidying are the same, and are not described in detail herein.
