Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a heating and cooking apparatus for cooking beans such as various kinds of Chinese food, stew, curry roux, custard cream, candy and the like, or red beans such as anko, soybeans, green beans and the like.

[0002]

2. Description of the Related Art A rotary stirring apparatus comprising a rotating spherical and disk-shaped pot and stirring blades fixed inside thereof has been used for heating the rotary stirring heating cooking apparatus. In the conventional heating, heating by steam is generally performed inside a jacket provided outside the kettle. The heating by steam is 85% efficient and more efficient than gas heating efficiency of 50% or less. On the other hand, recently, electromagnetic induction heating using a kettle, that is, an electromagnetic coil provided below the heating vessel, has been known. This heating by electromagnetic induction is more efficient with an efficiency of 92%.

[0003]

In the heating of this rotary stirring heating cooking apparatus, it is general to heat the mixture for a short time with high heat in order to give a good taste, in order to leave a good aroma. In the heating by steam, the temperature is raised by using a reflux boiler or the like. In order to raise the temperature quickly, it is necessary to increase the heat conduction area. The electromagnetic induction heating does not need to have a large heat conduction area, but requires a large electric power. For example, taking "sauteed onion" as an example, at home, put a direct heat on a gas in a frying pan (cooker), heat the oil to some extent, add oil, add onion that has been cut in advance, and fry quickly. At this time, if the thermal power is weak, the water will be released from the onion, resulting in a messy state. However, when fried with a high heat gas direct flame, water does not separate, and in fact, water can be separated, but the amount of heat is large and moisture evaporates quickly. In order to mass-produce this for industrial use, it must be performed in units of 50 kg and 100 kg at a time, and a large amount of heat is required. In the case of "Kimpara burdock", for example, if the calorific value is insufficient, it becomes a crunchy cooked food, and the product is remarkably inferior. In this case, too, by performing a high calorific value in a short time, a responsive product is completed, and the commercial value increases. However, steam of 2-3 kg / cm ² is a sticky product due to lack of calories, and is currently being shipped out.

[0004] In order to solve such a problem, the present invention combines the features of the above-described heating by steam and electromagnetic induction heating to achieve a desired short-time heating by a high heat with a relatively small heat conduction area and small electric power. It is. Another object of the present invention is to provide a sanitary device that is easy to repair, replace, and clean when the stirring blades that are in sliding contact with the inner surface of the kettle are worn to prevent the material from being scorched.
