Abstract
A method of extracting liquid from wet material in a fluidized bed is characterized in that in a circulating fluidized bed created mechanically by a mixing means, the material is thoroughly mixed, essentially in its entirety and in that in a first stage of the method, using the heat potential of the wet material, the liquid contained at below atmospheric pressure is at least partially evaporated and in that in a second stage of the method which follows on immediately from the first, heated gas is passed through the fluidized bed, the drying process being completed by at least partial saturation of the gas with the vapor from the liquid which is to be extracted.
