According to the situation of heat-exchange, we can classify it into direct heating and indirect heating. For indirect heating, it is quite low in the thermal efficiency. While, for some plants, this way is quite convenient for central heating. Water steam, generated by heating water in boiler, heats the drying medium through the radiator. While, for the way of direct heating, it is effective in heat utilization and great in thermal efficiency. This way is preferential for making finished products that are not easy to be influenced by dust.
