With more than 1,800 units in operation, the "RF" series dryers are Stalam’s best sellers. They are multi-purpose dryers particularly suitable for yarn in packages and cakes as well as for worsted fibres (tops) in bobbin and bump form.

RF dryers have proven to be very effective when fitted after the baking ovens to control the product moisture content accurately and uniformly, with added benefits to productivity and quality. The radio frequency energy eliminates the excess moisture from the product rapidly and efficiently, without causing over-baking (excessive browning) of the surface.

Traditional pasteurisation methods use hot air circulation, dripping hot water or direct steam injection into the treatment cabinet or tunnel for heating the packaged food. The temperature rise of the product is slow and non-uniform due to poor thermal conductivity of the packaging material, of the air or modified atmosphere contained in the package and within the food substrate itself. In order to reach a given temperature level in the coldest spot of the product a proportionally long heating time is required, affecting in particular the outside layers of food that are more exposed to heat. Consequently, the product loses its quality in terms of sensorial (colour, flavour, texture, etc.) and nutritional characteristics.
