The multiple drying slides 11 arranged in layers and tiltedly allow the tea drying tray 6 to slide towards the exit of the drying slide 11 under the action of its own gravity, and the tea drying tray 6 on each drying slide 11 can be automatically arranged quickly. In order to make the tea drying tray 6 slide down smoothly, a bottom sliding component is added, and the bottom sliding component is used to allow the tea drying tray 6 to slide down along the tilted drying slide 11. The bottom sliding component is fixed on the drying slide 11, and the drying blocking component is fixed at the exit of each of the drying slides 11 to control whether the tea drying tray 6 slides out of the drying slide 11.

[0035] Furthermore, the bottom sliding component can be a non-powered component, such as a plurality of follower rollers arranged side by side and fixed on the drying slide 11, or the bottom sliding component can be a powered component, such as a drying belt conveyor component. Both of these structural methods can enable the tea drying tray 6 to slide smoothly toward the exit of the drying slide 11.

The drying tea stopping assembly is used to control whether the tea drying tray 6 on the current drying tea slide 11 slides out.

[0038] Specifically, the drying linear power component is an electric cylinder, a pneumatic cylinder or an electromagnet.

[0039] Furthermore, in order to accurately control the time when the tea drying tray 6 is placed on the multi-layer drying mechanism 1, a sensor is used to detect the time when each tea drying tray 6 enters the drying slide 11, and timing is performed.

[0053] More specifically, Figure 1 As shown, the tea drying line is a U-shaped structure, and the straight conveying mechanism 3 and the right-angle turning mechanism 4 cooperate to realize the horizontal transmission and circulation of the tea drying tray 6. On the straight conveying mechanism 3, the material-taking and blocking components are arranged at the inlet and outlet docking points with the external tea shaking equipment, so as to facilitate the positioning and use of the tea drying tray 6.

The tea leaves are then transported to the multi-layer drying mechanism 1 for automatic drying of the tea leaves.
