[0027] The drying box cultivates the colony on a tray and places the tray into a box 2 for closed electric drying. The grid frame 8 is used to carry the tray and is powered by a motor 9 to drive the tray to rotate. Before opening the box 2, the fan 3 powered by the motor 9 is used to discharge the high-temperature gas inside the box 2 from the active air port 7 on the top of the box 2. The active air ports 7 on both sides of the box 2 dry the room-temperature gas outside the box 2 and send it into the box 2 to balance the air pressure, thereby preventing moisture in the air from affecting the cultivation of the colony. When the high-temperature gas is discharged, the door panel 6 is opened again, and the push rod 4 is used to push the tray out. At this time, the side rod 5 serves as a moving track for the tray to prevent the tray from falling.

[0028] See also Figure 4 As shown, the fan 3 includes a top cover 21, an exhaust port 22 and a bracket 23. The top cover 21 is installed on the upper surface of the box body 2, the exhaust port 22 is set at the center of the top cover 21, and the bracket 23 is installed in the top cover 21 and is below the exhaust port 22 and connected to the fan 3.

[0029] The top cover 21 is used to install the fan 3 to prevent the fan 3 from occupying too much internal space of the box 2. The exhaust port 22 is used to install the movable air port 7 on the top of the box 2. The bracket 23 provides positioning for the installation of the fan 3. Through the rotation of the fan 3, the high-temperature gas inside the box 2 is discharged from the top to avoid damage to the staff at the opening of the box 2.

[0030] See also Figure 1 to Figure 3 As shown, the push rod 4 includes a first groove 41 and a single-sided frame 42 . The first groove 41 is arranged on the side wall of the box body 2 facing the door panel 6 . The push rod 4 is located in the first groove 41 and connected to the single-sided frame 42 .

[0031] The push rod 4 is a telescopic rod structure. The single-sided frame 42 is pushed out by the extension and retraction of the push rod 4. The single-sided frame 42 and the side rod 5 in the box body 2 clamp the pallet and send it out of the box body 2.
