Hot air do not directly blow to the body, as far as possible from the body below the uniform blowing in all directions, so that moisture from the lid vent hole.

2. Induction heating method

is to put the body in the tank, the external winding coil through the power frequency current, using the fuel tank wall eddy loss of heat to dry. At this point the temperature of the box wall should not exceed the 115~120℃, the body temperature should not exceed 90~95℃. In order to winding the coil convenient, as far as possible to make the coil turn the number less or the current is smaller, the general current selection 150A, the wire can be useful 35~50mm2 wire. The tank wall can be padded with asbestos strips, and the conductor is wound around the asbestos strip.
