Abstract:Drying high moisture content of ammonium poly vanadate is a critical step in most of its industrial applications. Microwave drying can be used as a traditional drying substitute due to its unique heating characteristics. In the study, the effects of microwave power, sample mass and initial moisture content on microwave drying of ammonium poly vanadate were investigated by microwave drying system. Microwave power, sample mass and initial moisture content have a significant effect on microwave drying ammonium poly vanadate, which all can promote the absorption of more microwave energy to accelerate the evaporation of water. Microwave drying process can reduce the generation of dust, which is a clean and efficient energy efficient technology.
