Operation Principle: The top-vent fan-type wood drying kiln uses saturated steam as the heat source and moist air as the medium. It automatically or manually controls the parameters of the drying medium, utilizing the heat transfer by convection of the gas medium and the mass transfer science to dry the wood.

1. After the fan is started, it first blows the dried medium towards the radiator. After heat exchange, the temperature of the dried medium increases, and the heated medium is then directed towards the wood spread, raising the wood's temperature and initiating the vaporization and evaporation of moisture within the wood.

2. The air circulation within the drying room moves along the height and horizontally across the material stacks. The motor's timed reversal facilitates reversible media circulation, ensuring more even wood drying.

3. The medium humidity inside the drying room is increased by spraying steam and decreased by exhaust air.
