Abstract
PURPOSE: A part of exhaust gas of dryer is re-circulated to give an adequate temperature to the heating gas in the inlet of dryer. By doing so, damage of the granular material inside the dryer can be prevented.
CONSTITUTION: Drying material is fed to a hopper 8 by a belt conveyor 7 and to a dryer 1 in its inlet side 11 from a chute 10 and then it is transferred to an outlet side 12 of the dryer. On the other hand, combustion gas produced in a heat air productin furnace 2 is fed to the dryer 1 from its outlet side 12 by a burner 19. The combustion gas passed through the dryer body is absorbed an exhaust gas cyclon 3 through an exhaust gas tube 15. The exhaust gas in which fine particle of the burnt material is separated is sunctioned by an exhauster 4 and is exhausted outside from an exhaust tube 22. A part of this exhaust gas is supplied to a mixing chamber 19 by a circulation tube 23 so as to give the humidity to the combustion gas fed to the inside of the dryer 1.
