The blowing motor 110 drives the fan blade 111 to rotate, and the fan blade 111 is driven to rotate. Blade 111 blows wind into the refrigeration pipe 112, and the wind is converted into cold wind through the refrigeration pipe 112. The wind is filtered by the filter screen 113 and then blown out through the adjustment cover 114 to take away the heat on the surface of the forming tray.
