<P>PROBLEM TO BE SOLVED: To detect conditions of stirring and to reliably perform proper stirring in a steaming apparatus for heating soup and foodstuffs for steaming housed in a treatment tank with saturated steam. <P>SOLUTION: The steaming apparatus houses boiled foodstuffs made of solid foodstuffs and fluid soup in the treatment tank 1 and heats the foodstuffs 5 by introducing the saturated steam in the treatment tank 1. In the steaming apparatus, during the steaming process in which foodstuffs are cooked by maintaining a prescribed steaming temperature in the treatment tank, pressure in the treatment tank is temporarily made lower than saturated steam pressure at a steaming temperature to perform stirring under reduced pressure in which the inside of the foodstuffs is boiled to stir the foodstuffs. The steaming apparatus is provided with a foodstuff temperature sensor 14 for detecting foodstuff temperature in the treatment tank 1. An operation controller 13 detects the completion period of decompression on the basis of the temperature of foodstuffs detected by the foodstuff temperature sensor 14 when performing stirring under reduced pressure. <P>COPYRIGHT: (C)2012,JPO&INPIT |
