PURPOSE:To reduce a volume of main fuel to be supplied, to decrease an occurrence of carbon or soot and to prevent an occurrence of fire by a method wherein an inclination detecting sensor may detect an inclined state of a burner and a desired volume of main fuel to be fed into a main combustion chamber is corrected and controlled. CONSTITUTION:When a drying operation is started, an inclination sensing sensor 4 detects an inclined condition of a burner 8, a hot air temperature setting knob is operated to cause a hot air temperature to be set at a desired hot air temperature. An amount of fuel to be supplied into the burner 8 with a fuel supplying device 1 is reduction corrected with a correction device in response to a stored desired amount of fuel in a controller device and then grains are dried at a hot air temperature lower than the desired hot air temperature. When the inclination sensing sensor 4 detects that the burner 8 is inclined, an amount of major fuel to be supplied into the burner 8 through the fuel supplying device 1 is decreased, thereby the eccentrical combustion in the burner 8 is decreased, resulting in that an occurrence of carbon or soot is decreased. |
