Infrared contact drying

Infrared contact drying

Infrared drying refers to the radiation dryers type. In dehydration process the IR rays are directly exposed into the product. The radiation is emitted by infrared radiation lamps or heated surfaces.

From a theoretical point of view, infrared radiation is a more efficient means of delivering energy for heating the internal layers of a product than traditional methods, but in fact traditional techniques allow to smooth the difference by properly chosen drying modes. As such, the method of infrared drying is not widely used in industrial drying. This is due to the fact that only the electricity that produces the appropriate radiation is suitable for the true IR drying. And in a real economy, electricity is the most expensive form of energy. Therefore, the infrared drying mode is only reasonable in the regions where there is a large economy power supply and only together with microwave dryers.

However, IR dryer can be used as a helper method that can speed up the dehydration process. In such case, it is combined with convective, conductive or sublimation drying.

Unfortunately, some unscrupulous companies are trying to use the ignorance of the customers, and attribute to the infrared method of drying the "unprecedented properties" and improved performance. But under the guise of IR dryers the usual convective dryers are supplied only at a price several times higher than the average market price, which significantly increases the payback time of the drying plants as a whole.
