Jacketed heat lamps have a quartz glass casing on the outside. They are most commonly used in commercial food service establishments. The outer “jacket” or “sleeve” prevents splashing of food liquids and debris from causing lamp failure, prevents accidental damage, and better resists impact breakage.
They are ideal for food heating and are widely used in catering equipment to keep food at optimum temperatures. Such as food display heating counters (hot food displays and cold food displays) and serving tables.
How to choose an infrared heating lamp suitable for keeping food warm?
Power selectionConsider the quantity and volume of food: If it is used for small family gatherings or personal use, mainly to keep a small amount of food (such as one or two dishes) warm, an Halogen Heater Bulb Replacement with a power of 300-500 watts can meet the needs. For example, a heating lamp with a power of 300 watts can keep the temperature of a dish (about 500-800 grams) within a suitable range in a short time. But if it is used in commercial places, such as the buffet area of a restaurant, a large amount of food needs to be kept warm at the same time, and a heating lamp with a power of 1000-2000 watts may be needed to ensure that the food in many plates can stay hot.
Combined with the use environment and time: If it is used in a small closed environment (such as a small dining car), and the insulation time does not need to be very long, a lower power infrared heat lamp for warming is more suitable because it can avoid the environment temperature from being too high. But if it is in a larger open restaurant or canteen, and needs to be kept warm for a long time, in order to ensure sufficient heating effect, a heating lamp with higher power should be selected.
Wavelength range selectionDifferences in heating effects of different wavelengths: The wavelength range of infrared is relatively wide, generally divided into near infrared (wavelength 780-2500nm), mid-infrared (2500-5000nm) and far infrared (5000-10000nm). Near infrared mainly heats the surface of food quickly, and is suitable for food that needs to be heated quickly, such as fried food that has been cooked but the temperature has dropped. Mid-infrared and far-infrared can penetrate the surface of food and heat the inside of food, which is more suitable for food such as large pieces of meat that need to be heated from the inside to maintain temperature.
Choose according to food type: For foods with high water content (such as soups and vegetables), since water molecules have a strong absorption capacity for mid-infrared and far-infrared, it is better to choose a catering lamp near wave infrared heating lamp that emits mid-infrared or far-infrared wavelength ranges. For some solid foods that need to be heated quickly (such as bread and pastries), near-warming catering lamp for food warming can restore their crispy crust in a short time.
Size and shape of infrared heating lamp oven parts food warm lampMatch food containers and placement: If it is used to heat small containers of regular shape (such as sauces in small bowls), you can choose small, round infrared heating lamps, which can better focus the heat on the container. For heating large rectangular plates (such as buffet plates), rectangular heating lamps can more effectively cover the surface of the food and reduce heat waste.Consider installation and ease of use: Some foldable or small heating lamps are easy to store and move, suitable for use in home kitchens or small event sites. In fixed places such as commercial kitchens, larger and more solid heating lamps may be selected, and can be installed on specific brackets or walls for easy operation and adjustment of irradiation angles.
Temperature regulation functionPrecise temperature control: Jacketed Infrared Heat Lamp for Food with good temperature regulation are very important. Different types of food require different insulation temperatures. For example, the holding temperature of hot dishes is generally 60-80℃, while hot soup may require 70-85℃. Heating lamps with precise temperature adjustment knobs or digital displays can easily set the appropriate temperature according to the type of food to avoid overheating or overcooling of food.
Safety and energy saving considerations: The temperature adjustment function can also reduce the temperature to a lower maintenance temperature after the food is kept warm, which not only prevents overheating of food but also saves energy. For example, during non-peak dining hours in restaurants, appropriately lowering the temperature setting of the electric food heating element can reduce electricity consumption.
Quality and safetyBrand and reputation: Choosing food catering heating lamp from well-known brands can guarantee quality to a certain extent. For example, brands such as Henruite and Hengruite usually undergo strict quality inspections and have high product reliability. You can check consumer reviews and professional evaluations to understand the quality of the product.
