Burning paddy husk in a rice husk furnace can be a complete substitute for gas or diesel by burning paddy husk to provide necessary thermal energy. This not only increases the farmer’s income through significantly reducing drying cost and improving grain quality, it is also an important 21st century drying industry breakthrough.
