ABSTRACT:
A cake of biomass, preferably a peat cake, is dewatered by being pressed at a temperature above 90.degree. C., whereby the water in the cake is displaced by warmer water under successively increased pressure. An apparatus designed as a closed wash press is then used, in which the cake is subjected to dewatering, washing or displacement by warmer water and consequently heating as well as roller pressing.
