Radio frequency dryer

continuousfor the textile industryfor processing applications

Overview
RF drying concentrates electromagnetic energy in water present in hair bundles, enabling controlled dielectric heating at 27.12 MHz inside a temperature‑controlled tunnel with minimal air circulation. The process is designed for industrial drying of natural hair extensions, providing uniform, repeatable moisture reduction without thermal damage.

Key features

• Dielectric heating by RF at 27.12 MHz targeting water in the hair
• Temperature‑controlled tunnel with minimal air flow to avoid mechanical stress
• Energy absorption proportional to water content for precise moisture control
• Uniform drying regardless of hair fineness, texture or bundle size
• Effective on bundles bound by cords, elastics or sewn on supports
• Short cycle time: complete drying in just a few minutes
• No over‑drying, no wet spots, no hair entanglement

Conveyor and thermal management
Bundles are carried on a fine‑mesh conveyor that promotes evaporation while preserving the physical integrity of the hair. Low operating temperatures prevent thermal degradation and maintain biological, aesthetic and functional properties of natural fibers used in extensions.

Energy efficiency
Because RF energy heats water directly rather than the surrounding air, losses to the environment are minimized, resulting in lower energy consumption compared with conventional hot‑air systems and improved operating economy.
