New RF Dryer Reduces Drying Time and Increases Energy Efficiency

Press Release Summary:

  • Provides volumetric heating and simultaneously heats the product through their entire thickness and removes the moisture
  • Eliminates the carbon dioxide emissions associated with other drying methods
  • Is a low temperature process and not exceeds 100°C

Original Press Release:

Radio Frequency Company, Inc. is Introducing a New (RF) Dryer for Producers of Nonwoven Battings and Hydrophilic Foams

Producers of nonwoven battings and foams are faced with unique drying challenges due to the insulative characteristics of these products. When drying by conventional methods, longer residence times are required to allow the heat to penetrate into the inner portion of the products and remove moisture. The unique volumetric heating provided by RF drying systems simultaneously heats these products throughout their entire thickness and removes the moisture by converting it to a gas in situ. This greatly reduces drying times, significantly increases the energy efficiencies of the drying process, and eliminates the carbon dioxide emissions associated with other drying methods.

Further, because the moisture is turned to gas in situ, the migration of suspended solids such as binders, anti-microbial agents, colors, etc., is eliminated. This prevents the formation of a surface crust and enhances the uniformity, performance, and hand feel of the product. The RF drying process is a relatively low temperature process generally not exceeding 100ºC making it perfect for temperature sensitive materials. However, for formulations that require higher temperatures for curing or cross-linking of polymeric materials, systems can be supplied with integrated hot air assist modules to boost the processing temperatures required for various formulations.

Radio Frequency Company offers comprehensive testing facilities in its RF laboratory located in Millis, Massachusetts. All systems are compliant with OSHA, FCC and CE regulations and carry the UL label.
