How does a rice cooker magnet work?
The movement of the current through these coils creates a magnetic field. It is into this magnetic field that the rice cooker's pan is inserted. The magnetic field produces an electrical current inside the cooking pan, and this generates heat.
An electric current is passed through coils around the pot. This produces a magnetic field, which in turn produces an electric current in the pot's metal. Metal heats up when an electric current runs through it, so the entire pot quickly rises to a high temperature and cooks the rice evenly.
The best temperature to store grains, including rice, is 40°F or below; however, rice stored at a constant 70° F with oxygen absorbers will store well for up to 10 years. In cooler storage areas rice sealed in oxygen-free containers can be stored for up to 30 years.
Once the rice has absorbed all the water, the temperature will begin to rise past 212 degrees (the boiling point of water). When the thermal sensor senses this, the system turns off the heat and switches to the “keep warm” cycle.
Rice cookers works by transferring heat in the means of thermal conduction. The substance itself does not flow, rather the heat is transferred internally, by vibrations of atoms and molecules.
MCCB is known as the abbreviation of thermal magnetic, compact switch in the industrial field. Thermal magnetic switches generally provide protection at a current value in the range of 10 to 1600 amperes. In particular, they show the feature of protecting the system against overloading.
They work by boiling water, which is then absorbed into the rice until it becomes tender. Rice cookers are automatic, which frees up your employees to work on other tasks while the rice cooks. You also don't have to worry about a rice cooker boiling over or scorching.
In the induction heating rice cooker (an induction heater that consists of an electromagnet and an electronic oscillator) a high-frequency AC current is passed through the electromagnet. Eddy currents are generated in the material of the heating plate that distributes the heat to the pot for cooking the rice.
It consists of a heat source, a cooking bowl, and a thermostat. The thermostat measures the temperature of the cooking bowl and controls the heat. Complex, high-tech rice cookers may have more sensors and other components, and may be multipurpose.
Parts of Rice Cooker and Their Functions
A rice cooker (the machine itself, without accessories) consists of an inner pot, a thermostat, a heating element, a control panel, and the main body that holds them all together. The only thing you have to do to cook rice is to place it into the pan and add water.
Why does my rice cooker keep turning off?
The rice cooker automatically turns off when the temperature inside the pot exceeds waters boiling point (212 degrees F or 100 degrees C at sea level), which will not happen until all the free water has vaporized.
How do restaurants keep rice warm? A restaurant that serves a lot of rice probably uses a large crock-pot or slow cooker to keep the rice warm until it's ready to be served. You can actually do the same thing. Start by pouring a 1⁄2 inch (1.3 cm) layer of water into the slow cooker.
Tips on serving rice safely
Keep rice in the fridge for no more than 1 day until reheating. When you reheat rice, always check that it's steaming hot all the way through. Do not reheat rice more than once.
Dry white rice has a shelf life of up to 2 years, while brown rice keeps up to 6 months. Signs of expired rice include holes in the packaging, bugs, water, and mold. Brown rice may become rancid, oily, or discolored.
A basic rice cooker has a main body (pot), an inner cooking container which holds the rice, an electric heating element, and a thermostat. The bowl is filled with rice and water and heated at full power; the water reaches and stays at boiling point (100 °C, 212 °F).
Basically, you turn the multimeter knob to the continuity setting, place the needles on either side of the thermal cutoff, and listen for the beep. If the multimeter doesn't beep, there's no continuity, which means that the thermal cutoff needs to be replaced.

#3 A Broken Thermostat
- Unplug your rice cooker and let it cool down.
- Identify the screws holding the outer case in place and remove them.
- Expose the appliance's guts.
- Find your thermostat and access it.
- Test the part for conductivity.
