  • DRYING OF EFB BY HYBRID SOLAR/BIOMASS THERMAL

    Drum drying: in drum drying, the heated surface is the envelope of a rotating horizontal metal cylinder. The cylinder is heated by steam condensing inside, at a pressure in the range of 200 to 500 kPa bringing the temperature of the cylinder wall to 120–155°C.The wet material is applied on the drum surface as a relatively thin layer by a variety of different methods to be described later.

    In most cases, biomass drying is only economic if preheated air is available at low or no cost (examples are solar air collectors and the utilization of preheated air from flue gas condensation units – see Section 3.3.5). By drying biomass in piles for several months, a significant amount of the water evaporates by natural convection.
