After the rotary rack 3 rotates 90 degrees, the mesh tray 10 on the rotary rack 3 can be switched between the drying area 6 and the cooling area 7. The mesh tray 10 with the silicone buttons can dry the silicone buttons after being rotated from the cooling area 7 to the drying area 6, and the mesh tray 10 with the silicone buttons can cool the silicone buttons after being rotated from the drying area 6 to the cooling area 7, which facilitates the taking and placing of the silicone buttons.

The silicone buttons on the mesh tray 10 in the drying area 6 have been dried and are rotated into the cooling area 7 for cooling. After the silicone buttons in the drying area 6 are dried again, the silicone buttons in the cooling area 7 have also been cooled.
