Halogen infrared heating tubes for tunnel drying ovens
Efficient heating performance
Rapid heating: Halogen infrared heating tubes heat up very quickly, usually reaching operating temperature within seconds and outputting a large amount of infrared heat. In tunnel drying ovens, this rapid heating feature can greatly shorten the preheating time of the drying oven. For example, for a small tunnel drying oven with a length of 10 meters, using a halogen infrared heating tube for preheating, compared with traditional heating methods, the preheating time may be shortened from the original 30-40 minutes to 10-15 minutes, thereby improving improve the overall operating efficiency of the equipment.
High energy conversion efficiency: Halogen infrared heating tubes have a high efficiency of converting electrical energy into infrared radiation energy, generally reaching about 70% – 80%. This means that most of the electrical energy can be effectively converted into heat for drying, reducing energy waste. In long-term operation of tunnel drying ovens, this efficient energy conversion can significantly reduce energy costs.
Uniform heating characteristics
Good temperature distribution: The infrared rays emitted by the halogen infrared heating tube can form a relatively uniform temperature field in the tunnel drying furnace. Through reasonable layout and design, such as installing multiple sets of heating pipes on the top and sides of the tunnel drying furnace, the materials in the drying furnace can be heated evenly during the transportation process. In some drying applications that require high temperature uniformity, such as drying electronic components, drying food, etc., the temperature difference can be controlled within a small range, generally reaching ±5°C – ±10°C. , effectively avoiding drying quality problems caused by local overheating or undercooling of materials.
Penetrating heating: Its infrared radiation has a certain penetrating ability and can penetrate deep into the interior of the material to be dried for heating. For some materials with a certain thickness, such as block wood, ceramic bodies, etc., this penetrating heating can ensure that the materials are evenly dried from the inside to the outside. For example, during the drying process of wood, the infrared rays of the halogen infrared heating tube can penetrate the surface of the wood, accelerate the evaporation of moisture inside the wood, increase the drying speed, while ensuring the quality of the wood and reducing deformation and cracking caused by uneven drying. etc. questions.
Precise temperature control
Sensitive temperature regulation: Halogen infrared heating tubes respond more sensitively to the temperature control system. In the temperature control process of the tunnel drying furnace, the temperature in the furnace can be accurately controlled by adjusting the power of the heating tube. With advanced temperature sensors and controllers, the temperature can be controlled within a very precise range to meet the temperature requirements of various drying processes for different materials. For example, when drying pharmaceuticals or fine chemical products, the temperature control accuracy can reach ±2℃ – ±3℃, ensuring the stability of the drying process and product quality.
Fast temperature response: When the temperature of the tunnel drying oven needs to be adjusted, the halogen infrared heating tube can respond quickly. This is very beneficial in situations where the temperature needs to be dynamically adjusted based on material characteristics or drying progress. For example, in the early stage of drying, a higher temperature is needed to quickly evaporate a large amount of water, and then in the later stage of drying, the temperature needs to be lowered to avoid overheating of the material. Halogen infrared heating tubes can quickly respond to these temperature changes and improve the flexibility of the drying process.
Adaptable to a variety of materials and drying processes
Applicability to various materials: Halogen infrared heating tubes can be suitable for drying many different types of materials, including but not limited to food, textiles, wood, ceramics, electronic components, chemical products, etc. Whether it is powder, block, flake or linear materials, they can be effectively dried under infrared radiation. For example, in food drying, fruit slices, dried vegetables, dried meat products, etc. can be dried; in textile drying, cloth, yarn, etc. can be dried.
