An automatic rice cooker is an automated catering equipment for dining halls. It operates by adding rice and water in a specific ratio to the container, then activating the mixing system to blend them evenly. Subsequently, the heating system warms the rice in the pot to an appropriate temperature and maintains it for a certain duration to ensure it's fully cooked. The mixing system is then restarted to blend the cooked rice evenly, resulting in a soft and delicious texture.
