Short-wave infrared halogen heating elements are used in drying tunnel furnaces:
Efficient heating mechanism
Short-wave Quartz IR Halogen Heating Bulb in drying tunnel furnaces mainly achieve efficient heating by emitting short-wave IR Halogen Heating Bulb. The wavelength range of short-wave Quartz Heater Bulbs is generally between 0.76 and 2.5μm. This short-wave Infrared Heating Elements can be efficiently absorbed by the material to be dried.
When the material absorbs short-wave quartz tungsten halogen heat lamps, the vibration and rotation of its internal molecules (such as water molecules, organic component molecules, etc.) intensify, and the molecular kinetic energy increases rapidly, causing the material temperature to rise rapidly. For example, in the food processing industry, for vegetables that need to be dried, short-wave tungsten infrared heat lamp can quickly penetrate the surface of vegetables, causing the water molecules inside the vegetables to heat up quickly and accelerate the evaporation of water.
Fast drying characteristics
Due to the high energy characteristics of short-wave infrared radiation, it can quickly evaporate the water in the material in a short time. In the environment of a drying tunnel furnace, the material can continue to be radiated by the Shortwave Infrared Heating Lamps while passing through the tunnel furnace.
For example, in ceramic production, after the ceramic body is exposed to short wave infrared radiation in the drying tunnel furnace, the moisture in the body can evaporate in large quantities within a few minutes. Compared with the traditional hot air drying method, its drying speed can be increased several times, greatly shortening the drying cycle and improving production efficiency.
Uniform drying effect
Short wave Quartz Infrared Heating Element can provide a relatively uniform radiation field. In the drying tunnel furnace, by reasonably arranging the heating elements (such as evenly distributed at the top and sides of the tunnel furnace), it can be ensured that all parts of the material can be exposed to uniform short-wave infrared radiation.
For irregularly shaped materials, such as coating drying of industrial parts, this uniform drying effect is particularly important. Because uneven drying may cause problems such as uneven thickness and color differences in the coating on the surface of the material. Short wave Quartz Infrared Heating Lamps can penetrate the coating to a certain depth, so that the inside and surface of the coating are heated at the same time, ensuring the uniformity of drying.
Accurate temperature control
Short wave halogen IR heating lamp can be easily combined with temperature control systems. By adjusting the power, radiation distance and other parameters of the heating element, the temperature in the drying tunnel furnace can be accurately controlled.
In different drying processes, materials have different optimal drying temperature ranges. For example, in the wood drying process, the optimal drying temperature for coniferous wood and hardwood is different. Using the precise temperature control function of the short wave Quartz Infrared Halogen Heating Elements, the appropriate drying temperature can be set according to the type, size, moisture content and other factors of the material to ensure the drying quality while avoiding damage to the material due to excessive temperature.
Energy-saving advantage
The short wave Electric Infrared Heat Lamp directly transfers the short wave Infrared Heat Lamp Replacement energy to the material, reducing the loss of heat during the transfer process. Compared with the traditional hot air drying method, there is no need to heat a large amount of air first and then transfer the heat to the material through the air, so the energy-saving effect is significant.
In large-scale industrial drying processes, such as building materials, chemical industry and other industries, this energy-saving advantage can reduce production costs, improve economic benefits, and also meet environmental protection requirements.
