Infrared heating lamps are used to keep food warm: Working principleQuartz Infrared Halogen Heating Elements mainly heat by quartz halogen heat lamp ir lamp.infrared halogen heating lamps are an electromagnetic wave with a wavelength range of 780nm – 1mm. When infrared quartz lamp replacement are irradiated on the surface of food, the molecules in the food absorb the energy of infrared rays, causing vibration and rotation. The intensification of these molecular movements leads to an increase in the internal energy of the food and an increase in temperature, thereby achieving the effect of keeping warm.Infrared heating is a radiation heat transfer method, which is different from traditional heat conduction (such as heat transfer through metal pots) and convection (such as hot air circulation). It does not require a medium to transfer heat and can directly transfer heat to food, so the heating speed is relatively fast.AdvantagesEnergy-saving: Infrared Quartz Heat Tube have a high energy conversion efficiency when converting electrical energy into heat energy for food insulation. Compared with some traditional insulation methods, such as using hot water baths or hot air circulation insulation equipment,infrared quartz heat lamp can transfer heat to food faster, and after reaching the insulation temperature, they can maintain low energy consumption through suitable temperature control devices. For example, in the self-service area of ​​a restaurant, the energy consumption of food kept warm by infrared quartz heat lamp may be 20% – 30% lower than that of traditional electric heaters under the same insulation effect.Better temperature uniformity:high temperature resistance quartz glass tubes can heat the surface of food more evenly. Through reasonable lamp layout and irradiation angle adjustment, it can be ensured that all parts of the food can receive sufficient infrared radiation. This is very beneficial for the insulation of various foods such as barbecue, vegetables, etc. on the buffet table. Unlike the local temperature differences that may occur in heat conduction or convection, infrared heating can reduce the situation where the taste and quality of food are affected by local overheating or overcooling.Maintain food quality: Since infrared heating mainly heats the surface of food and heats quickly, it can reduce the water loss and nutrient damage of food during long-term insulation to a certain extent. For example, for some roasted meat products, under the insulation of tungsten near infrared lamps, the skin can remain crispy and the meat inside is still tender and juicy, which is better quality than food that has been left in hot air for a long time and blown dry.Quick response: After the infrared heating lamp is turned on, it can quickly reach the working temperature and start heating and keeping the food warm. Generally speaking, high-quality infrared heating lamps can reach effective insulation temperature within 1-2 minutes, which is very convenient for catering places (such as cafeterias and buffet areas in restaurants) where new food needs to be frequently added for insulation.Precautions for useDistance control: The distance between the Heating Infrared Bulb and the food has a great impact on the insulation effect and food quality. If the distance is too close, the surface of the food may be burned due to excessive heating and high temperature; if the distance is too far, it may lead to poor insulation effect. It is generally recommended to control the distance to about 15-30 cm according to the power of the heating lamp and the characteristics of the food. For example, for some easy-to-cook foods such as pastries, the distance can be slightly farther, about 25-30 cm; and for meat foods that need to maintain a higher temperature, the distance can be 15-20 cm.Temperature adjustment: In order to avoid overheating or overcooling of food, the temperature of the Heating Infrared Bulb needs to be reasonably adjusted according to the type and quantity of food. Different foods have different optimal insulation temperatures. For example, the insulation temperature of hot soup can be set at 70-80℃, while the insulation temperature of fried foods can be set at 60-70℃. At the same time, when adding new food for insulation, due to the low initial temperature of the food, it may be necessary to increase the temperature of the heating lamp appropriately, and then adjust it back to the appropriate insulation temperature after the food temperature rises.Safety issues: Halogen Lamp Replacement Parts generate heat when working, and the surrounding temperature is high. Therefore, be careful to prevent burns during use. Flammable items should be avoided around the Halogen Bulbs, as high temperatures may cause fires. At the same time, make sure that the power connection of the Halogen Heater Bulb Replacement is firm and safe, and regularly check the lamp for signs of damage, such as broken bulbs and aging wires.Comparison with other insulation methodsCompared with traditional electric heater insulation: Traditional electric heaters mainly transfer heat through hot air convection, and the heating speed is relatively slow. Moreover, hot air easily causes moisture loss on the surface of food, causing the food to dry out. Infrared Halogen Heater Parts directly heat the surface of food, which can better maintain the moisture and taste of food.Compared with hot water bath insulation: Hot water bath insulation is to place the food container in hot water and transfer heat to the food through heat conduction. Although this method can make the food heated evenly, the temperature control is not flexible enough, and during the long-term insulation process, the food may absorb too much water, affecting its original flavor.ceramic heater bulbs can flexibly adjust the temperature according to the needs of the food, and the food will not absorb too much water.
