Boiling water is the primary function that a rice cooker performs. The boiled water is then absorbed by the rice, which gradually becomes tender. Usually, rice cookers function automatically once you switch them on. Therefore, you can do your other kitchen or household tasks while keeping your rice cooker in the oven until the rice gets cooked properly.

Rice Cooker vs. Slow Cooker vs. Pressure Cooker  

Due to their different functions, rice cooker, slow cooker, and pressure cooker have some integral differences based on their working methods, application, maintenance, price, convenience, safety, power requirement, etc., that you should be aware of before selecting the ideal cooker for your kitchen. 

1. Operational Differences

Rice Cooker

Rice cookers use electrical energy as the internal energy of the cooking equipment so that the cooking time for rice can be reduced. A basic rice cooker structure includes a temperature limiter, thermal plate, current limiting resistor, socket, light, lever switch, and other important parts.

Different stages through which the rice gets cooked are – sitting in water, boiling, steaming, and resting. In simple rice cookers, the heating plate transfers the heat to the cooking pan for warming up the contents such as rice and water. Being made of highly conductive metals such as copper or aluminum, the cooking pan transfers the heat faster.

The next functional steps of a rice cook are easy enough to understand. 100 degrees Celsius or 212 Fahrenheit temperature is needed to boil water. Once the water starts boiling stably, its temperature does not increase. The temperature will remain the same until water exists in the cooker. 

As soon as the water gets absorbed by the rice, you will observe the temperature rising. This change is perceived by the rice cooker and goes on a cycle of warming. It is the moment when the cooker will finish cooking the rice and then enter the resting phase. 

Pressure Cooker

The working method of a pressure cooker is no rocket science. The entire cooking process depends on steam pressure. A sealed container produces a lot of pressure due to the high amount of steam inside it which speeds up the cooking procedure. 

The sealed container of the pressure cooker features a valve that keeps the internal pressure in check. As soon as the pot's temperature goes up, superheated steam is produced by the inside liquid, and it gradually increases the pot's pressure.

Due to the formed high pressure, there are two types of impact. In liquid-based food like soup, stew, or steamed vegetables, the cooking temperature is restricted to the boiling point of water (100 degrees Celsius or 212 F).

However, with the help of steam's pressure, the temperature can increase up to 250 F, which stimulates the fast cooking of the food. The liquid and moisture are also absorbed into the food quite rapidly because of the high pressure, which expedites the cooking process and makes solid food items like meat softer. 

Slow Cooker

Slow cookers are a very convenient device for cooking meals in an automatically set timer, where the time required for cooking the meal ranges from 2 hours to 8 hours.

The mechanism on which these slow cookers work is similar to a stovetop pot, as the base of these slow cookers heat up and spreads the heat within the pots evenly to distribute the required amount of heat to the food being cooked.

These programmable slow cookers are such that you can set the temperature at high or low and then set a timer for cooking, after which the slow cooker begins its works and gets your meal ready accordingly. This is why slow cookers are best for making one-pot meals compared to pressure cookers or rice cookers.

The lid of the slow cookers is used to cover the pot and seal it, which promotes even distribution of heat and good cooking. A striking feature of this slow cooker is that once the meal is cooked, the warming mechanism springs into action, which consequently helps maintain the warmth within the cooker and keeps your food warm for longer periods.


2. Different Applications

Rice Cooker

Obviously, the best function of a rice cooker is for boiling rice, which turns out perfectly. Going beyond what the name suggests, rice cookers are not merely used for rice cooking; rather, rice cookers are used for multiple other purposes like preparing hot cereals quickly, cooking vegetables, tofu, chicken breast, fish fillets, and even shrimp.

However, rice cookers can also be used for steaming purposes. For certain vegetables, chicken, fish or even dumplings, rice cookers work wonderfully. An amazing feature of rice cookers is that they can easily prepare one-pot meals without requiring mixing or stirring the ingredients within. 

You can also use a rice cooker efficiently for making stews, soups, or beans by adding a sufficient quantity of water and the required spices and herbs along with every other ingredient. 

Pressure Cooker

Pressure cookers work wonderfully for cooking several food items. The multiple purposes that a pressure cooker serves include boiling food, braising them, and even simmering the food. This covers a lot of food items which can be cooked very easily.

Some of the dishes which can be conveniently cooked by using pressure cookers include stews, stocks, and soups. You can also use a pressure cooker to cook many vegetables like carrots, beans, and beetroots. It can also be applied for the pressure cooking of whole grains, dried beans, polenta, risotto, and many more such items.

Furthermore, unlike rice cookers, braising of items such as meat, chicken, and so on can be carried out very conveniently with the help of pressure cookers. The best electric pressure cookers in India come with automated option for cooking various dishes. They are easy to use and maintain.

Slow Cooker

Slow cookers are amazing electrical devices that function wonderfully in cooking multiple dishes very easily. This is because the mechanism used by slow cookers is such that it distributes heat evenly to the food being cooked, and this gives slow and complete cooking.

Although we generally use slow cooker for cooking rice or one-pot meals, there are many other purposes that a slow cooker serves, which include boiling, baking, and even frying. Thus, slow cookers can also be used for making stews, stocks, soups, and casseroles too but their applications are limited when compared to a pressure cooker.


3. Health and Safety
