A food warmer is an appliance designed to keep cooked food at a safe and desirable temperature until it is ready to be served. These devices are commonly used in restaurants, catering services, and buffets to ensure that meals remain warm and appetizing for customers. Food warmers can come in various forms, including countertop models, heated cabinets, and even portable units. Most food warmers operate using electricity and can maintain temperatures between 140°F and 165°F (60°C to 74°C), which is crucial for food safety. They are often equipped with features like adjustable temperature controls and humidity settings to prevent food from drying out. Food warmers are essential for maintaining the quality of dishes, especially in high-demand settings like catering and hospitality.
