Food heat preservation lamps are mainly used in catering places to keep food temperature.
It generally achieves heat preservation function through infrared heating. The working principle is that the internal heating element (such as tungsten wire, etc.) emits infrared rays, which can penetrate the air and be absorbed by the food, making the food molecules move more rapidly and thus heating up. This heating method is more efficient and can make the food reach the appropriate temperature in a short time, and can maintain the temperature continuously. It is often used on buffet tables in restaurants to keep the food hot and tasty for a certain period of time.
