Rice cookers, also known as electric rice cookers, are kitchen appliances that use electrical energy to generate heat and cook food. These devices are not only convenient and easy to use but also promote cleanliness and hygiene in the kitchen. Modern rice cookers come with a wide range of functions such as steaming, boiling, stewing, and simmering. They have become essential household appliances, significantly reducing the time families spend on cooking.
The first rice cooker was developed in 1950 by Tokyo Communications Engineering Company, a renowned Japanese firm. Since then, rice cookers have evolved into multifunctional appliances. Today, they can cook rice, make porridge, prepare soups, even bake cakes, and some models can pressure-cook without water. This versatility helps save both money and space in the kitchen.
There are three common types of rice cookers: basic thermal insulation, timed insulation, and advanced microcomputer-controlled models. In this article, we will explore the features and benefits of rice cookers, helping you understand how to choose and use them effectively.
When purchasing a rice cooker, consider several factors. First, look for reputable brands that offer good quality, customer service, and warranty support. A multi-functional model is ideal, as it can perform various cooking tasks and save counter space. Energy efficiency is another important aspect—some models use purple sand inner pots, which may take longer to cook rice and consume more power compared to traditional metal liners.
Safety is crucial. Always check for a 3C certification mark on the product, including the plug and power cord. The instruction manual should clearly list the product name, model number, voltage, and power rating. Ensure the package includes a warranty card, accessories, and a factory certificate.
Before buying, inspect the rice cooker’s appearance. Check for scratches, dents, or deformation. Make sure the parts fit smoothly, the inner pot coating is even and durable, and the indicator lights work properly. Test the heating plate to ensure it gets hot when powered on.
Using a rice cooker is straightforward. Most models have an automatic shut-off system based on temperature. When the internal temperature reaches 100°C, the magnetic switch turns off the power. If the rice isn't fully cooked, the temperature remains below 100°C, and the cooker stays on. For steaming, add water to the inner pot, place the steaming tray, cover, and let it cook for about 30 minutes. Once the water evaporates, the rice will be soft and delicious.
Leaving cooked rice in the cooker for too long can cause the top layer to dry out. To prevent this, place a layer of clean cloth over the rice before cooking. Rice stored at temperatures between 25°C and 40°C can spoil quickly, but most rice cookers maintain an insulation temperature of around 65°C ± 5°C, which prevents bacterial growth. However, in summer, rice may develop a sour smell if left too long.
Never scrub the inner pot directly with abrasive materials. Always handle the inner pot carefully, ensuring it sits flat and aligned inside the cooker. Avoid using other pans instead of the original inner pot, as this can damage the heating element and increase energy consumption.
To save energy while using your rice cooker:
1. Soak the rice for 15 minutes before cooking. This reduces cooking time and enhances flavor.
2. Use residual heat after the rice starts boiling. Turn off the power, wait 8–10 minutes, and then resume cooking if needed.
3. Avoid using the rice cooker as a kettle. It takes much longer to boil water compared to a dedicated kettle.
4. Keep the inner pot clean. Over time, oxide buildup may occur, so soak and wipe it regularly to maintain performance.
With proper care and usage, a rice cooker can be a valuable and efficient tool in any modern kitchen.
