METHOD AND APPARATUS FOR DRYING PULP

摘要

A method and device for drying fibre-containing pulp. The wet pulp is first dewatered mechanically e.g. by means of a drum or screw press (10), after which the pulp is taken to the dryer (12) proper in which water is evaporated from the pulp by utilising hot gas or the like. In the dryer the pulp is dried in a gap (20) formed between the first and second surfaces (16', 18') provided with apertures, in which the pulp layer is arranged to travel through the dryer. Drying gas is passed through the pulp layer travelling in the said gap in order to evaporate water from it.
