This apparatus involves feeding black tea raw materials to be roasted into the material bin via a hopper, and supplying air into a support platform via a blower. A heater heats the connecting pipes, transferring heat to S-shaped heat-conducting pipes evenly distributed within the support platform, ensuring uniform heating of the air. The hot air then flows upward through a diversion hole, which divides the hot air and ensures it passes evenly over a spiral feeding plate, resulting in uniform heating of the black tea on the plate. Simultaneously, a motor drives a rotating rod, causing the spiral feeding plate to rotate and moving the black tea raw materials to the right.

[0023] Specifically, the material receiving assembly 6 includes a collecting box 61, a separating mesh box 62 and a moving piece 63, the lateral wall of the heating mechanism 7 and below the discharge pipe 5 is fixedly connected with the collecting box 61, the inside of the collecting box 61 is provided with the separating mesh box 62, and the moving piece 63 is arranged between the collecting box 61 and the separating mesh box 62,

[0024] Through the above technical scheme, the baked black tea is discharged through the discharge pipe 5 and falls into the separation net box 62, and then the separation net box 62 is driven to move in the collection box 61 by the moving piece 63, so that the black tea inside the separation net box 62 is shaken, and the broken branches and leaves mixed in the black tea fall into the bottom of the collection box 61 through the gaps in the separation net box 62, so that the black tea and the broken branches and leaves are separated and collected, and the quality of the baked black tea is ensured.

[0025] Specifically, the moving piece 63 includes a reset spring 631, a fixed column 632, a moving groove 633, a moving plate 634, and a through hole 635. The moving plate 634 is fixedly connected to the side wall of the separation net box 62. The moving groove 633 is formed in the side wall of the collection box 61. The fixed column 632 is fixedly connected to the inside of the moving groove 633. The through hole 635 is formed in the moving plate 634 and corresponds to the position of the fixed column 632. The reset spring 631 is fixedly connected between the moving plate 634 and the moving groove 633.

[0026] Through the above technical scheme, the moving plate 634 is moved along the moving groove 633. During the movement of the moving plate 634, the fixed column 632 and the through hole 635 can provide a guiding effect for the movement of the moving plate 634, thereby improving the stability of the movement of the moving plate 634. When the moving plate 634 moves and collides with the inner side wall of the moving groove 633, the impact force is transmitted to the inside of the separation net box 62, so that the broken branches and leaves mixed in the black tea inside the separation net box 62 fall into the bottom of the collection box 61 through the gaps in the separation net box 62. Then, the moving plate 634 is released, the reset spring 631 loses the external force and returns to its original state, thereby driving the moving plate 634 to move.

[0031] In use, the red tea raw materials required for processing and production of black tea are injected into the material box 4 through the hopper 1, and then the spiral conveying mechanism 8 and the heating mechanism 7 are started. The spiral conveying mechanism 8 drives the red tea raw materials to move inside the material box 4. In the moving process of the red tea raw materials, the heating mechanism 7 can be used to perform baking operation on the red tea raw materials. The baked black tea is discharged through the discharge pipe 5 under the action of the spiral conveying mechanism 8. The discharged black tea falls into the separation net box 62 under the action of gravity, and at the same time, the moving plate 634 moves upwards along the moving groove 633. In the moving process of the moving plate 634, the fixed column 632 and the perforation 635 cooperate to provide guidance for the movement of the moving plate 634, thereby improving the stability of the movement of the moving plate 634. The moving plate 634 drives the return spring 631 to stretch. When the moving plate 634 moves and collides with the inner side wall of the moving groove 633, the impact force is transmitted to the inside of the separation net box 62, so that the branches and leaves mixed in the inside of the separation net box 62 fall into the bottom of the collecting box 61 through the gaps on the separation net box 62. Then, the moving plate 634 is loosened, the return spring 631 loses the external force and restores to its original state, thereby driving the moving plate 634 to move. The moving plate 634 drives the separation net box 62 to move. In the moving process of the separation net box 62, the branches and leaves mixed in the inside of the separation net box 62 fall into the bottom of the collecting box 61 through the gaps on the separation net box 62 under stress, and slide along the material guiding table 64. The branches and leaves are discharged to the periphery of the collecting box 61 through the material outlet 65, so as to ensure the separation effect of the black tea and the branches and leaves, thereby facilitating the operator to separately collect the black tea and the branches and leaves, and ensuring the quality of the baked black tea.
