Food warmers are appliances designed to keep cooked food at a safe and desirable temperature until it is ready to be served. They are commonly used in restaurants, catering services, and buffets to ensure that dishes remain warm without overcooking. Food warmers come in various types, including electric warmers, steam tables, and heat lamps. These devices help maintain food quality and safety by preventing bacterial growth that can occur when food is left at room temperature. Many food warmers are equipped with temperature controls and indicators, allowing users to monitor and adjust the heat as needed for different types of cuisine or dishes.
