RADIO FREQUENCY DRYING SYSTEMS

High frequency dielectric heating is proven to be the most efficient method of moisture removal for both natural and synthetic textiles. Strayfield offers the textile industry an extensive product range with many advantages over conventional drying methods.

Since introducing radio frequency (RF) drying systems to the textile industry over 30 years ago, Strayfield has remained an innovator and world leader in this technology.

Today the company has many hundreds of RF systems installed all around the world. These are in use drying everything from bump tops to the very latest in technical packages.

MAXIMUM EFFICIENCY

Today, yarns are being wound denser and are becoming more thermally-sensitive. This means it is necessary for Strayfield to ensure that its equipment can operate at maximum efficiency and still dry yarns at low temperatures, for example at 80°C for cotton). All systems are specially tuned to achieve these results.

As winding technology advances and fibres continue to become more thermally sensitive, Strayfield’s technologies have advanced too. The ‘second generation’ Strayfield systems incorporate RF with ‘intelligent vacuum’ to ensure very low drying temperatures are maintained, at approximately 65°C, and with smaller generators.

Strayfield now offers dryers up to 125kW in capacity, which are capable of processing up to 8 tonnes of cotton in an hour, depending on input/output moisture levels.
