For modern home rice cookers, the smallest single-person model cooks 1 rice cup (180 ml), whereas large models can cook 10 cups. Commercial models can cook 20 or more cups. As a possible source of confusion, model specifications and names may list either cooked or uncooked capacity. Rice roughly doubles in size during cooking; therefore, a 10 cup (uncooked) rice cooker can produce up to 20 cups of cooked rice. The prices vary greatly, depending on the capacity, features, materials used, and the country of origin.
These inventions include, e.g., microprocessor-controlled cooking cycles, employing pressure cooking, utilizing induction heating (IH) that can generate heat directly within the inner cooking bowl itself (all the IH-type models are microprocessor-controlled), employing a varying pressure control mechanism (named the "dual-pressure" method) that creates repeated pressure/release cycles during the cooking, using various materials (e.g., copper, pure carbon, ceramic, diamond powder coating) for the inner cooking bowl because of their higher heat conductivity, utilizing more than one induction heating element, or employing a mechanism to collect and return the boiled over liquid to the inner rice bowl. The rice cookers which are very large to store tons of rice are used in places like Guruvayur.[clarification needed]
The pressure-cooking models can raise the water's boiling point higher, e.g., from 100 °C at 1.0 atm up to about 110 °C at 1.4 atm, which speeds cooking. They are also suitable for cooking brown rice (which contains oils and bran fiber that cook differently from pure white rice starch). The pressure-cooking models can also be used in high altitude areas.Using a rice cooker is a simple and effective way to cook rice. Many rice cookers keep the rice warm after it's cooked. There's no need to watch the rice cooker since this appliance comes with an automatic timer that clicks when the rice is ready. This article will show you how to cook rice with a rice cooker so that you can minimize the chance of burnt rice and ruined pots.
1.Measure the rice with a cup and put it into your cooking pot.
