DETAILED DESCRIPTION

[0030] Example 1: Reference Figure 1-Figure 10 , a tea processing device for avoiding damage to tea leaves comprises a fermentation barrel 1, a barrel seat 2, a fixing seat 3, a fixing cylinder 4 and a plurality of loading boxes 5; the fermentation barrel 1 is horizontally rotatably arranged in the barrel seat 2, a barrel cavity 201 with two horizontal ends penetrating therethrough is provided in the middle position of the barrel seat 2, the outer wall of the fermentation barrel 1 is rotatably connected to the inner wall of the barrel cavity 201, the fermentation barrel 1 is transmission-connected with a driving mechanism, and a heating unit is arranged in the barrel seat 2; one end of the fermentation barrel 1 is opened, and a through hole is provided at the other end of the fermentation barrel 1, the outer wall of the fixing cylinder 4 is in sliding contact with the inner wall of the through hole, the fixing seat 3 is fixed to one end of the barrel seat 2 near the through hole, a base is installed between the fixing seat 3 and the bottom end of the barrel seat 2, and the fixing seat 3 is fixedly installed to the outer wall of the fixing cylinder 4; a plurality of loading boxes 5 are distributed in a circular array on the inner wall of the fermentation barrel 1 and the outer wall of the fixing cylinder 4 , and there is sliding contact between two adjacent loading boxes 5, and there is sliding contact between the outer wall of the loading box 5 and the inner wall of the fermentation barrel 1 and the outer wall of the fixed cylinder 4. The loading box 5 and the fermentation barrel 1 are fixed by a buckle limit. The loading box 5 is an arc-shaped structure, and one side of the loading box 5 and the end position facing the fixed cylinder 4 are opened; the middle position of the top and bottom of the fixed cylinder 4 is provided with a leakage groove 401. When in use, the tea leaves are piled up and loaded into one or two loading boxes 5, and the empty loading box 5 is horizontally slid in from the top position between the fermentation barrel 1 and the fixed cylinder 4, and the loading box 5 filled with tea leaves is slid in from the bottom area to ensure that the tea leaves will not fall when sliding in. After sliding in, the loading box 5 and the fermentation barrel 1 are limited and fixed by the buckle, and the opening side of the loading box 5 corresponds to the sealing side position of the loading box 5 at the adjacent position;

[0031] During the fermentation operation, the fermentation barrel 1 is heated from the outside by the heating unit, and the fermentation barrel 1 and the loading box 5 are rotated in a circle around the horizontal axis by the driving mechanism to perform the fermentation operation. The loading box 5 rotates toward the opening side, and a plurality of loading boxes 5 are distributed in a circular array on the periphery of the fixed cylinder 4 so that each loading box 5 is arranged in an arc-shaped structure, so that when the loading box 5 rotates in a circle around the fixed cylinder 4, the tea leaves can be naturally turned over in the loading box 5 to disperse the tea leaves; at the same time, when the sealing side of the loading box 5 is close to the leakage groove 401 at the upper position, part of the tea leaves originally at the upper part and close to the fixed cylinder 4 will fall from the upper leakage groove 401, And the tea leaves pass through the leakage groove 401 below and fall into other loading boxes 5, so that the multiple loading boxes 5 rotate with the fermentation barrel 1 and the position of the fixed cylinder 4 is always fixed, so that the tea leaves can be naturally turned over in the loading boxes 5 and between the multiple loading boxes 5. On the one hand, the tea leaves are dispersed by effective turning over to avoid tea leaves accumulation affecting the fermentation effect, and on the other hand, direct mechanical drive to cause the structural parts to directly collide with the tea leaves, thereby avoiding damage to the dry tea leaves. Therefore, through the arrangement of the fermentation barrel 1, the loading box 5 and the fixed cylinder 4, the dispersion effect of the tea leaves during the fermentation process is effectively improved, and the damage of the tea leaves during the turning process is effectively avoided.

[0032] In the present invention, a gear ring 6 is fixed to the outer wall of the fermentation barrel 1, and a driving mechanism is provided with a driving motor installed at the bottom of the barrel seat 2. A gear 7 is fixed to the output shaft of the driving motor, and the gear 7 is meshed with the gear ring 6, so that the driving motor is used to realize the rotation operation of the fermentation barrel 1 during the fermentation process. Two slide bars 101 are fixed at the position corresponding to the barrel seat 2 on the circumferential outer wall of the fermentation barrel 1, and a slide groove 202 with an annular structure is opened at the position corresponding to the slide bar 101 in the barrel seat 2. The slide bar 101 and the slide groove 202 are in sliding contact with each other to ensure the stability of the circumferential rotation of the fermentation barrel 1.

[0033] In the present invention, a plurality of limit bars 102 are fixed to the inner wall of the fermentation barrel 1, and the limit bars 102 extend in the axial direction of the fermentation barrel 1. A limit groove is provided at a position corresponding to the limit bars 102 on the outer wall of the loading box 5, and openings are arranged at both ends of the limit groove to cooperate with the buckle between the loading box 5 and the fermentation barrel 1 to ensure the stability of the loading box 5 as the fermentation barrel 1 rotates in a circle.

[0034] In the present invention, the portion of the fermentation barrel 1 located between the two slide bars 101 is made of heat exchange material, mounting grooves 8 are provided on the tops of both sides of the barrel seat 2, and the heating unit is provided with a heating element 9 fixed in the mounting groove 8. The heating element 9 is used to heat the fermentation barrel 1 to cooperate with the fermentation operation.

[0035] In the present invention, sealing covers are provided at both ends of the fixed cylinder 4, and one end of the fixed cylinder 4 away from the fixed seat 3 is connected to the exhaust pipe 10, and an exhaust valve is provided on the exhaust pipe 10. The fixed cylinder 4 is connected to the opening of the loading box 5 through the leakage groove 401, so that the residual gas in the fermentation area can be discharged through the exhaust pipe 10.

[0036] In the present invention, horizontally placed air ducts 11 are provided on both sides of the fixed cylinder 4, and the two air ducts 11 are distributed on both sides of the leakage groove 401. One end of the air duct 11 is connected to a fan through an air pipe. A plurality of horizontal air inlets 111 are provided on one side of the air duct 11 facing the leakage groove 401, and air inlets 112 are provided at both ends of the bottom of the air duct 11. During the fermentation process, the air duct 11 is ventilated by the fan so that the gas is ejected from the air inlets 111 and 112. The gas ejected horizontally from the air inlet 111 toward the leakage groove 401 is convenient for blowing away the tea leaves naturally falling from the upper leakage groove 401. The gas ejected vertically downward from the air inlet 112 cooperates with the arc surface in the fixed cylinder 4 to assist in pushing the tea leaves into the leakage groove 401 below to fall, so as to further improve the dispersion effect during the tea fermentation process.

[0037] In the present invention, the sealing covers at both ends of the fixed cylinder 4 are respectively configured as a cylinder cover 13 and a cylinder cover 2 14. The cylinder cover 13 is located at one end of the fixed cylinder 4 close to the fixed seat 3. Both sides of the cylinder cover 13 are fixed with vertical linear guides 15, and the linear guides 15 are connected to the ends of the air ducts 11. The two air ducts 11 reciprocate in the vertical direction, and the two air ducts 11 move in opposite directions, so that the two air ducts 11 reciprocate in the vertical direction and intersect at the middle position. When the two air ducts 11 are vertically separated, there is only a single-direction horizontal wind force at the corresponding position, which pushes the separated tea leaves to one side in conjunction with the gravity of the tea leaves agglomerated in a single tea box. When the two air ducts 11 are close to each other, local cross wind force will be generated to disperse the agglomerated tea leaves, thereby further improving the dispersion effect of the fermented tea leaves through the vertically staggered movement of the air ducts 11 and the turning operation of the rotation of the loading box 5, and effectively avoiding excessive collision damage to the tea leaves.

[0038] In the present invention, a vertically extending through groove 141 is opened at a position corresponding to the air duct 11 on the second barrel cover 14, and the outer wall of the air duct 11 is in sliding contact with the inner wall of the through groove 141. The end of the air duct 11 toward the through groove 141 extends to the outside, and a vertically extending baffle 16 is fixed to the circumferential outer wall of the air duct 11. The baffle 16 is in sliding contact with the outer wall of the second barrel cover 14, and the cross-section of the baffle 16 is larger than the cross-section of the through groove 141. On the one hand, the end of the air duct 11 slides at the position of the through groove 141 and is limited by the baffle 16 to reduce the load of the linear guide 15. On the other hand, the baffle 16 covers the position of the through groove 141 to ensure relative sealing in the fermentation area, and only the exhaust pipe 10 is used to control the exhaust operation.

[0039] Embodiment 2: Embodiment 2 includes all structures and methods of Embodiment 1, with reference to Figure 1-Figure 10 , a tea processing device for avoiding damage to tea leaves, further comprising: a plurality of leakage holes 402 are opened on both sides of the fixed cylinder 4, the leakage holes 402 are located below the axis of the fixed cylinder 4, a horizontally placed shaft rod 17 is arranged at a position corresponding to the leakage holes 402 in the fixed cylinder 4, a blade 19 is fixed to the bottom of the outer wall of the shaft rod 17, both ends of the shaft rod 17 are rotatably connected with a shaft sleeve 18 through a bearing, and the shaft sleeve 18 is fixedly connected to the inner wall of the fixed cylinder 4, because the leakage holes 402 are located below the axis of the fixed cylinder 4, the tea leaves in the loading box 5 will not enter the fixed cylinder 4 in large quantities due to gravity when it is rotated to the corresponding position; and the tea leaves falling from the upper leakage groove 401 into the fixed cylinder 4 slide down along the inner wall of the fixed cylinder 4 due to the blowing of the air port 111, so that part of the sliding tea leaves fall from the leakage holes 402, so that the tea leaves in the fixed cylinder 4 fall from the leakage groove 401 and the leakage holes 402 on both sides under the action of the staggered air duct 11, thereby further improving the dispersion effect of the tea leaves during the fermentation process.
