Electric rice cookers, a variation of pressure cookers, don't necessarily need to be used only to cook rice. They can also be used to boil dal and sabzi.But not to fry or sauté. What differentiates a rice-cooker from a pressure-cooker is that though it cooks under covered pressure, it works more like a steamer - the lid is loosely fitted and is held down by its own weight.It consumes between 400W to 900W.
TYPES OF RICE COOKER
On/Off Rice Cookers
The least expensive rice cooker although it is perfectly capable of cooking a good batch of rice. Just add rice and water, and it will turn off once the rice is cooked. These lack many of the features seen in a higher priced cooker, such as non-stick rice pans, and indicator lights. They work well as a basic, small rice cooker.
Cook and Keep-Warm Cookers
This type of rice cooker has a feature that will automatically switch into a ‘keep warm’ mode once the rice is cooked. It becomes handy if you want to eat at different times. Many have built in steamers and other helpful features.
Fuzzy Logic Rice Cookers
These are programmable rice cookers that let you select different rice textures regular, soft, firm or modes that make cooking rice for soup, porridge and sushi a simple task.

These have an induction heating system and are high end rice cookers. This technology allows for even heating of the rice resulting in perfectly cooked rice. These cookers will have temperature sensing methods that are more accurate and heat distribution will be even throughout the entire rice pan, not just radiating from below. The level of heat can be adjusted accurately and instantaneously and the program can correct for measuring errors automatically by making adjustments to the cooking time and temperature.
