R7S 1500w 498mm halogen heat lamp used in the flash dryers
Infrared halogen medium wave heating tubes have many advantages in flash dryers. The following is a detailed introduction for you:
1. Heating efficiency
Rapid heating ability
Principle: Infrared halogen medium wave heating tubes can quickly convert electrical energy into infrared radiation energy. When the flash dryer is started, this rapid heating characteristic allows the temperature in the dryer to reach the set value in a short time.
Advantages: For flash dryers that need to quickly dry a large amount of materials, rapid heating reduces the preheating time and improves the overall operating efficiency of the equipment. For example, when processing a batch of powdered materials with a high moisture content, the use of infrared halogen medium wave heating tubes can shorten the preheating time of the dryer by 30% – 50% compared to traditional heating methods.
Efficient energy transfer
Direct radiation heating: The radiation characteristics of medium wave infrared enable the heat emitted by the heating tube to be directly absorbed by the material without the need for conduction through an intermediate medium. In the flash dryer, the material directly absorbs the infrared energy, achieving efficient heating.
Reduce energy loss: Compared with some methods of heating by hot air convection, this direct radiation heating avoids heating the surrounding air during the heat transfer to the material, thereby reducing energy loss. According to statistics, under the same drying task, the use of infrared halogen medium wave heating tubes can increase energy utilization by 20% – 30%.
2. Drying quality
Uniform heating characteristics
Uniform radiation principle: The infrared radiation emitted by the halogen medium wave heating tube is evenly distributed within a certain range. In the flash dryer, this uniform radiation ensures that all parts of the material can be heated evenly.
Improvement of drying quality: For various materials processed by the flash dryer, whether it is granular, powdered or flaky materials, uniform heating is crucial. For example, when drying pharmaceutical particles, uniform heating can prevent local overheating from causing deterioration of pharmaceutical ingredients and ensure the quality stability of the pharmaceutical.
Accurate temperature control and drying effect
Fast response speed: The infrared halogen medium wave heating tube has a small thermal inertia and responds quickly to temperature adjustment signals. During the drying process of the flash dryer, when the temperature needs to be adjusted according to the drying degree or characteristics of the material, the heating tube can quickly change the output heat.
Achieve precise drying: Through precise temperature control, the requirements of different materials for drying conditions can be better met. For example, when drying heat-sensitive materials, the temperature can be precisely controlled to avoid damage to the material due to excessive temperature, thereby achieving high-quality drying effects.
