<P>PROBLEM TO BE SOLVED: To solve problems with a pressure type electric rice cooker wherein the finished rice may be sticky or watery because dissolving of starch on the surface of the rice into water is accelerated if a high pressure is continuously applied in a boiling retention step, and wherein the finished rice may be hard or without a sense of fluffiness if the heating amount or heating time is controlled to such an extent as to keep the surface of the rice in a good state. <P>SOLUTION: According to this invention, rice boiling is executed while selectively using pressures at a plurality of levels between a high pressure higher than a normal pressure and an intermediate pressure relatively higher than the normal pressure according to the necessity. By adjusting the pressure within an inner pot 3 to, for example, three levels of pressures including the normal pressure state with no applied pressure, moisture and heat are permeated into the rice to accelerate gelatinization of starch, and at the same time, the stickiness and wateriness of the surface of the rice are controlled, so that fluffy rice can be boiled. <P>COPYRIGHT: (C)2013,JPO&INPIT |
