Exposing paddy to 60ºC for one hour can reduce the seed germination rate from 95% to 30%. Two hours at 60ºC will reduce the germination rate to 5%. mohave county planning and zoning commissionThe following are some general methods of drying: • Application of hot air (convective or direct drying). Air heating increases the drying force for heat transfer and accelerates drying. It also reduces air relative humidity, further increasing the driving force for drying.
