Infrared Heating With Microwave For Industrial Drying
Infrared heating can be used together with hot air heating for industrial drying process to get more uniform heat. Besides, infrared heating can also be used with microwave for industrial high temperature sterilization disinfection, and the production of ingredients drying. For example, the high temperature disinfection of various glass bottles, the drying of tea, the drying of soy products, dried spices, dried meat, and drying of mushrooms, fruits and vegetables. Infrared heating needs a small volume to distribute heating lamps and our infrared lamps are fast response. At the same time, it can be accurately regulated by PLC or SCR, which can be used as the preheating of tunnel drying to improve the production speed. Our infrared lamps can also be used as a mid -term constant temperature heating in drying machine. Infrared heating has a stable power output and is not affected by the outside air, so that the heated objects can obtain a uniform heating temperature. Infrared quartz lamps have special heating advantages compared to traditional heat sources, such as hot air, ceramic heaters, gas heaters or metal heaters. Infrared quartz heating lamps can deliver large amounts of radiation energy directly to heated objects, and the emit wavelength can be precisely matched to materials absorb, and the heating length and shapes are custom design. It has the following advantages: Infrared radiation does not need to contact the product and does not require the intermediate medium to transfer heat. Under the sunlight, the sunshine side is warm but the sunless side is cold. This is not due to temperature differences, but radiation heating, the heat energy of electromagnetic waves (infrared radiation) from the sun that is transferred to objects. The sun is the source of heating energy, so the infrared quartz lamps are the heating source for industrial heating process. Infrared quartz lamps can be precisely matched to the heated material, that is, effectively absorbed by the material. Different objects different matched IR radiation wavelength-IR lamp Short wave (0.9~1.4μm), Fast response medium wave (1.4~2.0μm), Carbon medium wave (2.0~4.0μm), Medium wave (2.2~4.0μm). Fast response time, adjustable output heat power. Short wave and fast medium wave IR heat lamps have 1~2 seconds fast response time to full power IR heating energy. The output heat power can be adjusted in percentages, so we can have accurate(±1 ℃) IR heating temperature in our machine or drying oven. It can heat the material partially or completely, control the heating area, and control the heating time. Compared with hot air or gas heating, this means less energy consumption, faster heating speed and better heating efficiency. For a successful heating process, it is important to select a suitable infrared lamp with wavelength, shape and heating power match the product being heated. Precise matching ensures that infrared radiation is quickly converted into heat in the product without transferring unnecessary heat to the surroundings, saving time and money.

Does turn on/off frequently will affect working life of infrared heat lamps?
When heating with infrared lamps, does turn on/off heating frequently will affect the working life of infrared heat lamps? The answer is yes. In circuit science, the moment the load is powered on, a large current is usually generated, which is the impact current. When starting infrared heating lamp, there is also a current impact. The start-up current is generally 4-7 times that of the rated current. If IR heat lamp is powered on and off frequently, the conductive element of the infrared heating tube will causes damage frequently, so we do not agree with the operation by turn on/off frequently our lamps. Case 1: T-shirts thermal transfer equipment with 220V 1600W quartz infrared heeat lamp, basically needs to be switched on and off lamp one time every 10 seconds, the heating equipment work 24 hours every day, this customer will turn on and off lamps 360 times every hour and 8640 times every day, especially the heating equipment which are using R7s connection sockets, turning on and off infrared heating so frequently will damage the connection parts between R7s socket and our infrared lamp. Case 2: There was one customer who switched on and off our twin tube IR lamps 3 times in 1 second, the operation is definitely not good to lamp, because heating elements cannot be restored and they will gradually produce volatile impurities. Case 3: Customers use medium wave infrared heating lamp. They want to turn off the heating when no workpiece on the conveyor. When the workpiece needs to be heated, the heating is turned on. If they turn on and off frequently, for medium wave infrared lamp, we do not recommend the customer to do this. Because the response time of medium wave heating lamp takes 1-4 minutes. If the workpiece is heated at this time, the heating temperature of the workpiece may not reach the required temperature, which will affect production efficiency. If you really need to turn on and off IR heating lamps frequently for researches, we can enhance the conductive components of the lamp to increase the working life of the lamp. Different customers have different control ways during infrared heating. If the heating involves frequent startups, we more hope that you use PLC or our SCR to adjust power output percentage of the way to control. The important that our SCR power regulator can control the starting current from 0 to rated current and no more impact on our infrared heat lamps.

How increase heating temperature with infrared quartz heat lamp?
1: Confirm your heating element types, replace your old high energy consumption resistance elements to transparent quartz infrared radiant heating lamps. It is well understood that as long as the temperature is higher than the temperature of other objects, heat transfer will occur naturally, so heat transfer is the main heating method of old resistance heating elements. VS For infrared heating lamps, the working principle is actually to emit infrared rays, the thermal effect of the infrared rays emitted by the infrared heating lamp is usually due to the electromagnetic interaction between the infrared rays and the molecules of the heated object. The small molecules absorb the electromagnetic energy. After the vibration is intensified, the temperature of the object continues to rise, thereby achieving heating. So the main heating method of quartz infrared heat lamp includes radiant heating and heat transfer. Infrared heating lamp radiates and conveys large amounts of energy in a short time. You can check the following video for our quartz IR lamp. If we want to increase the heating temperature, please choose the right heating elements. 2: Choose matched IR radiation wavelength for your heated objects By matching different optimum wavelength of infrared, our Quartz Infrared (IR) Heating Lamps are available for all industrial and scientific heating applications. Different objects different matched IR radiation wavelength. Metal objects absorb short wave (0.9~1.4μm), Solvent/Plastic materials abosrb fast response medium wave (1.4~2.0μm), Food/Water/Wood absorb medium wave (2.2~4.0μm), Carbon medium wave (2.0~4.0μm) are widely used in warming and sauna, also for other industrial heating applications. 3: Increase Heating Power Density We are custom IR lamp manufacturer and we can design IR heat lamps for your higher heating temperature requirement. The highest surface power output of shortwave IR lamp is 200KW/M2, Fast response medium wave IR lamp is 150KW/M2, Carbon medium wave IR lamp is 120KW/M2, Medium wave IR lamp is 100KW/M2 4: Increase Infrared Heating Time Adjust the speed of conveyor or increase the heating length. For example, if we have 2 meter long heating oven with quartz infrared heating lamps, normally we need 100 ℃ for the heated objects, now we need to increase the heating temperature to 120℃, we can lower the conveyor speed to have a longer heating time if available, or we can increase 0.5 meter ～1 meter heating length to make the heated objects have more infrared radiation. 5: Improve Temperature Protection For Infrared Heating Areas If your heating oven is open or no temperature protection, we suggest you add an proection wall with insulation cotton along infrared heating lamps. Infrared heating lamps are often used in industrial heating and drying, especially in the heating and drying process of surfaces such as automobiles, metal parts, food, glass, and circuit board packaging. Today, because infrared heating lamps can better save energy consumption, and this novel heating method has also been widely used in the industrial field, it has also developed more rapidly in the near future, and now it has also gained a very objective economic benefits.

Twin Tube Fast Response Medium Wave Infrared Emitters
Fast response medium-wave infrared emitters have the same product composition as short-wave infrared emitters. By changing the structure of the tungsten wire, use different radiant quartz body, its color temperature can be controlled around 1400-2000K, and then radiates most of infrared energy with a wavelength between 1.4-2.0 microns. Fast response medium wave infrared emitters not only have the advantages of high heat density, strong radiation ability, and fast start-up speed of short wave, but also have the gentle heat generation method of medium wave. It can directly radiat surrounding air medium to form convective heating, which is softer, more uniform and easier to control. Twin tube fast response medium wave infrared heating lamp can be controlled and adjusted the output power by PLC or SCR regulator automatically, so we can have accurate（±1 ℃）IR heating temperature in industry process. The heating filaments can be designed and work in 1200～1800℃ with 1~2 seconds fast response time, so the FMW IR lamp are widely used for fast heating application which needs heating temperature from 50～500℃.

Shortwave infrared lamp and medium wave infrared emitter
Under the sunlight, the sunshine side is warm but the sunless side is cold. This is not due to temperature differences, but radiation heating, the heat energy of electromagnetic waves (infrared radiation) from the sun that is transferred to objects. The sun is the source of heating energy, so the infrared quartz lamps are the heating source in industrial heating process. Infrared Heating Lamps are made of transparent quality quartz glass tubes and high temperature resistant alloy heating filaments. Quartz glass tubes as radiation body, when infrared lamps are working, the alloy heating filaments reach high temperature in seconds as a light source and emit out lots of infrared rays through quartz tube radiation body, meanwhile, surrounding objects will absorb these amounts of infrared rays from our quartz heating lamps and be heated very fast. If we install fast heating IR lamps in your machine or production lines, we can dry our products faster and increase our productivity. Infrared ray is a kind of electric wave, which propagates at the speed of light and carries high energy. Different types of infrared rays with the same power have different radiation intensity and different wavelengths. We encapsulate the high-temperature heating filaments (up to 2600°C) into quartz tube as an energy source of heating (quartz infrared heating lamp), when our quartz infrared lamp is power on, which radiates near-infrared, middle-infrared and far-infrared like sun. Short wave infrared heating lamp Shortwave infrared heating lamp can be designed with high heating power, the range of radiation wave is 1.0-1.4μm, it is particularly suited for fast response heating processes. This short wave infrared radiation penetrates more deeply into materials, as they can obtain infrared radiation full-efficiency within seconds. Meanwhile has the following advantages: 1. Fast response time, the heating temperature can rise and fall quickly 2. By combining with the reflection module, IR lamps can work in a small area by concentrating light or parallel irradiation 3. The lamp does not touch the heated object and can be used in a clean environment and no harmful 4. The working lamp is not disturbed by the atmosphere and external environment and can be used in a vacuum oven. 5. Inside of filaments can be designed and heat to 2200°C or higher, so the objects can be heated up to 1000°C or higher, depending on the material and size being heated. Medium wave infrared heating lamp Medium wave quartz infrared heater lamp are particularly suitable for the fast heating of surface or thin materials, and the range of IR radiation wave is 2.2-4.0μm. Plastic, water and other solvents absorb well this medium wave radiation. Because of its long working life （≥8000 hours）and economical efficiency, medium wave lamps are popular used in continuous heating processes, such as making natural herbal medicine or drying the tea in a continuous running oven. Medium wave IR lamp is made of quartz twin tube with sizes of 23×11mm or 33×15mm. The heating filament is Ni-Cr or Fe-Cr alloy material. The total length of twin tube medium wave IR lamp can be up to 6 meter. In order to better convey and focus on the heated material all the IR radiation emitted from the IR lamp, the special gold reflector or white reflector will be coated and fixed directly on the quartz surface.
