"RFA/HP" for yarn packages with a forced air circulation system in a conveyorised type dryer
This revolutionary drying equipment, specifically designed for yarn packages, combines the RF technology with a forced air circulation system through the product in a conveyorised type dryer.
It is the first time worldwide that a passing-through air flow can be obtained in yarn packages in a continuous throughput drying equipment.
The “RFA/HP” dryer has the highest hourly productivity among all Radio Frequency dryers having the same size RF generator, yet at a reduced drying temperature.
The air forced through the product is heated up to the desired temperature without using any external (additional) energy source by recovering the heat dissipated by the RF generator. Both the RF energy and the warm air forced through the product contribute to water evaporation. This combined process, other than being extremely efficient, enables a precise control of the product’s internal temperature, thus optimising the drying quality results.
