Halogen infrared heating lamps for food heat preservation and heating:
Working principle
infrared heating elements mainly generate infrared rays through filament heating. The filament is usually made of materials such as tungsten filament. After electricity is applied, current passes through the filament. Due to the resistance of the filament, the electrical energy is converted into heat energy, causing the temperature of the filament to rise sharply. When the filament temperature is high enough, it radiates infrared light. Infrared ray is a kind of electromagnetic wave. It has a significant thermal effect and can be absorbed by objects such as food, which in turn intensifies the molecular vibration of the object and increases the temperature, thus achieving the effect of heating and heat preservation.
Advantages in food insulation and heating:
1. Efficient heating: The heating efficiency of infrared is relatively high. On the restaurant’s buffet table, the use of infrared heaters infrared heat lamp bulbs can quickly heat and keep food warm, allowing the food to reach the appropriate eating temperature in a short time, and it can continue to be kept warm while customers are taking their meals.
2. Better temperature uniformity: Infrared Heater Replacement parts will be distributed evenly on the food surface, reducing local overheating. For example, when heating some pastries, the entire surface of the pastries can be kept warm, and there will be no phenomenon where some places are burnt and some are not yet hot.
3. High safety:infrared heaters with tungsten wire usually work at low voltage and generally do not produce open flames, reducing fire and other safety hazards. Moreover, the Infrared Heating Bulb has a protective device to prevent contamination of food after being broken, which is very important in a food heating environment.
4. Good visibility: During the heating process, staff and customers can intuitively see the status of the food. Because the light emits light, you can clearly observe whether the food is dry or discolored, making it easy to adjust the heating status or replace the food in a timely manner.
