Turn on or off the power.

Further, the movable tray is uniformly and densely covered with ventilation holes, the diameter of which is less than 5mm.

Preferably, the movable tray is located above the air inlet connection or the air inlet ventilation hole of the inner cavity, and the movable tray is located under the air outlet adapter or the air outlet ventilation hole of the inner cavity.

Further, there are 6 inner cavities.

Further, the outer wall of the hot air pipe is coated with an insulating coating.

The utility model has the following beneficial effects:

1. Since the inner cavities are connected in series, each inner cavity can pass through the same amount of uniform hot air, ensuring that the tea leaves in each inner cavity are evenly dried.

2. Hot air enters and exits from the top and bottom of the tea drying chamber, contrary to the conventional bottom air intake setting, so that the temperature and wind speed of the tea drying chamber gradually decrease from top to bottom.

3. According to the principle of aerodynamics, the shape of the air inlet pipe and the air outlet pipe of the hot air pipe is changed, so that the tea drying chamber of the drying box has a greater negative pressure when the drying box is working, and the wind speed of the hot air is increased. The energy consumed by the exhaust fan is saved.

Description of drawings

In order to more clearly illustrate the technical solutions in the embodiments of the present invention or the prior art, the following will briefly introduce the accompanying drawings that need to be used in the description of the embodiments or the prior art. Obviously, the accompanying drawings in the following description These are only some embodiments of the utility model, and those skilled in the art can also obtain other drawings according to these drawings without any creative effort.

Fig. 1 is the structural representation of the utility model.

Detailed ways

The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention.
