Ninchuewong et al, (2012) The drying of rubber sheets at moisture conditions from 25-40% dry-basis. moisture content to 0.5% dry-basis drying temperature 40-70○C wind speed 0.7 m/s, drying rubber sheets dried with hot air can be controlled. The appropriate drying temperature is in the range 50-60○C, to achieve the best physical rubber disc desiccation. (Ninchuewong et al, 2012)
