Why Choose Kerone Online Radio Frequency (RF) Dryer

Conventional mode of Drying Textiles after they have been dyed is a slow process. Textile industries can increase Throughput and fill orders more prominently using Radio Frequency (RF) Dryers. RF system has capability to accelerate the drying process and shorten production time. RF drying offers High Volume, High speed and High quality drying which is what exactly needed in textile industries. As wet garments of Acrylic, Cotton, Nylon and Polyester Blends pass through the drying chamber , the radio waves vibrates the contained Water molecules million times per second, vaporizing them. Ventilator Fans are used to remove damp air from the Drying Chamber. The dryer system comprises the 125kW industrial high frequency generator in conjunction with a drying chamber incorporating an electrode applicator and air extraction system. The equipment is suitable for drying most types of fibers which have had prior mechanical moisture extraction in either, cone and muff, bump or loose stock form. Many types of fiber can be dried. The machine incorporates a modular polypropylene conveyor band and conveyor system. Because of the RF waves concentrate in the wettest, densest portion of the garments. RF drying has a leveling effect that practically eliminates any problems of uneven shrinkage and over drying. The RF drying times depend on the type of fabric, the percentage of moisture in the fabric going in to the dryer, and the degree of dryness desired.

Types and Features of Online Radio Frequency (RF) Dryer

Online Radio Frequency (RF) Dryers are advanced drying systems that use high-frequency electromagnetic energy to remove moisture uniformly and efficiently from continuous web materials. These dryers operate on dielectric heating principles, ensuring deep penetration and volumetric heating, which reduces surface overheating and improves product quality. They are widely used in textiles, paper, nonwovens, and coated materials industries for precise and energy-efficient drying.
