SDA01-85 Radio Frequency Dryer

Stalam.Deyi Radio Frequency Dryer adopts the most advanced RF technology available worldwide and is the only one of its kind in the domestic market. It is designed for the continuous drying of hydro-extracted textile products and is suitable for all fibres and yarns such as synthetics (polyester, acrylic, nylon), artificial fibres (rayon, viscose) and natural fibres (wool, cotton, silk, etc.)
The radio frequency drying technology is based on the direct transfer of the electromagnetic energy to the water molecules contained in the wet fibres: the energy is only delivered to the product in proportion to its moisture content, with minimal losses in the surroundings, so the drying process can be carried out very efficiently.
The fast and easy penetration of the electromagnetic field into the product makes the drying process fast and uniform. A mild warm air circulation system in the drying cabinet helps in avoiding dew condensation and the low drying temperature achieved, thanks to the reduced RF power density adopted, allows to optimizing the quality of the fibrse in terms of bulkiness, mechanical strength, hand feeling and colour effect. All the above outstanding results cannot be achieved by any other conventional (atmospheric or pressurized) drying method.
The electron tube (triode) cooling is accomplished by means of a double water cooling circuit, that is designed to maximize its life time.
