[PDF]or fluidised-beds (Table 2). The superheated steam in the dryer provides the thermal driving force necessary to evaporate the moisture in the fuel. Generally, the wet material is mixed with enough superheated steam to dry the material and end with saturated steam. There are disadvantages to this process however; these

Steam Drying - an overview | ScienceDirect Topi

Drying with superheated steam: In this method of dehydration, the heating medium is superheated steam. The material to be dried is brought in contact with water vapors at a temperature considerably higher than the saturation temperature at the prevailing pressure.

SUPERHEATED STEAM DRYING AT ATMOSPHERIC PRESSU

[PDF]Principle of the superheated steam drying process The material to be dried is introduced to the superheated steam atmosphere where it is supplied convectively with heat and its moisture evaporates. Through the uptake of vapor released from the material, the volume of superheated steam increases, while its temperature decreases without changing
