Salient Features:
This is a mixing type drier-cum-roaster. The wet material is mixed with the preheated sand and thereby the moisture is removed or the material is roasted. Sand temperature could be controlled only by addition or removal of firewood or any agricultural waste. The mixture of hot sand with the crop can be easily separated and recirculated for continuous heating of the crop. The average fuel consumption is around 10-12 kg of firewood per hour. Sand gets heated up before being recycled again through return auger.
