Abstract

PURPOSE: To make proper cooking operation to suit the purpose by furnishing a variable speed driving part which performs either low-speed rotation of a turntable or high-speed rotation of a kneading blade. CONSTITUTION: In bread baking made by using a bread vessel 12, the vessel 12 is placed in a heating chamber 1, and bread material 13 is put in the vessel 12, followed by rotating a kneading blade 14 by a variable speed driving part 16 at 200 rpm around so that the material 13 is well kneaded, and then heat is applied appropriately by an upper heater 4 and a lower heater 5 and with high-frequency energy, and upon necessary processes including fermentation and gas bleeding with blade rotation for several sec, etc., the baking process as the final is performed. In case a turntable 19 is used, turntable 19 for placing of object to be heated 18 and a rotary table 20 to support the turntable 19 are installed in the heating chamber 1, and the turntable 19 is rotated at 5 to 6 rpm by the driving part 16. Thus, the object 18 can be cooked with heat given by the upper and lower heaters 4 and 5 or the high-frequency energy supplied into the chamber 1 from a high-frequency oscillator 2.
