The hot air or fuel, typically blown upwards, produces a turbulent ecosystem, igniting the raise and blend of particles. This rigorous blending permits ideal interaction involving the particles and the drying gases.

Temperature: Elevated temperature brings about elevated moisture diffusivity and consequently greater drying rate and diminished drying time. The nature of the fabric plays a vital position in picking out the operating temperature.
