annular body portion Air blowing air flue is input into by air-flow along the radial direction of the cylindric air blowing drying channel, and the cylindric drying of blowing is logical Road is used to be passed through for carrying the net formula conveyer belt of tealeaves, is annular between the annular outer cover part and the annular body portion Distribution of air flow chamber, be input into for receiving air-flow and by distribution of air flow to a plurality of radial direction air blowing air flue, the air-flow point Left and right two ends with chamber are provided with revolvable two air-flows input envelope of mutual specular in structure with being respectively symmetrically Closed loop, wherein, an air-flow input channel for axial direction is provided with each in two air-flow input closed-loops, and And for the air-flow input closed-loop on right side in two air-flow input closed-loops, the air-flow is input into a left side for closed-loop Connected by left side bearing between end and the annular body portion and passing on left in the rotation of left side in the left side bearing Sealing ring and seal cooperation, exterior seal ring is rotated by left side between air-flow input closed-loop and the annular outer cover part And seal and coordinate;The left and right sides of the drying airflow blow is fixedly connected with mutual mirror image in structure with being respectively symmetrically Symmetrical two air-flow input channel components for including main body ring part, in two air-flow input channel components For the air-flow input channel component on right side, its left side is fixedly installed convex extension part and is used to lead to towards the cylindric drying of blowing Road is stretched out so as to be positioned to the air-flow input channel component, and each in two air-flow input channel components is surrounding The periphery of the main body ring part is respectively arranged with air cavity housing so as between the air cavity housing and the main body ring part The annular air cavity with air-flow input port is formed, is provided with the air-flow input port during airflow filtering net is used to filter out air-flow Larger particle and dust, the airflow filtering net is made up of metal material, in two air-flow input closed-loops For the air-flow input closed-loop on right side, its right-hand member is extend into the annular air cavity, the excircle with the main body ring part Connected by right bearing and sealed by right side rotating interior seal circle on the right side of the right bearing between face and coordinated, and with institute The inner peripheral surface for stating air cavity housing rotates exterior seal ring and seals cooperation by right side;On a left side for the drying airflow blow Symmetrical two motors are respectively arranged with right two ends, the motor includes outer rotor and is arranged on described outer Inner stator in rotor, the inner stator is fixed on the upside of the annular outer cover part and the air cavity housing, described outer Rotor is fixed between the annular outer cover part and the air cavity housing and the periphery of the outer rotor is provided with rotor Accordingly to be engaged with the gear part being fixedly installed in the middle part of the air-flow input closed-loop, each described air-flow is input into gear Channel component is provided with tea leaf delivery channel to be connected simultaneously with the cylindric air blowing drying channel along central axial direction Passed through for the net formula conveyer belt;Thus, air-flow is input into so as to be input into via the air-flow by each described air-flow input port The air-flow input channel in closed-loop and in the distribution of air flow chamber that arrives, and then via a plurality of radial direction inflatable gas Road and the tealeaves in the cylindric air blowing drying channel that arrives to being carried on the net formula conveyer belt carries out air blowing drying, each The outer rotor of the motor can drive corresponding air-flow input closed-loop rotation so as to change the air-flow input channel Circumferential position, wherein, the inlet end of the air-flow input port is provided with solenoid electric valve, and the solenoid electric valve is used to control The supply of the
