Patent ID: 7887671

Claim:
A method for the dilution of dewatered and compressed cellulose pulp that has been consolidated into large pieces, where the dewatered cellulose pulp maintains a first consistency greater than 20%, comprising: fragmenting the cellulose pulp into a finely divided pulp after or in association with dewatering, thus granulating the cellulose pulp through said fragmentation to a particle size with a normal distribution with a maximum size that is less than 40 mm, while fragmenting, maintaining a consistency of the cellulose pulp that is essentially equivalent to the first consistency, feeding the cellulose pulp that has been finely divided through the fragmentation into a freely falling flow, adding dilution fluid under pressure towards the freely falling fragmented pulp through a number of fluid jets arranged in association with the flow of the freely falling fragmented pulp, the amount of dilution fluid added through the fluid jets establishing a second consistency of the cellulose pulp in a medium-consistency range 8-16%, feeding the cellulose pulp at this medium consistency 8-16% onwardly to subsequent treatment stages, a dilution of the freely falling pulp taking place essentially exclusively under an influence of hydrodynamic effect from the addition of the dilution fluid through the fluid jets, and where no mechanical agitation takes place between the fragmentation of the cellulose pulp and an underlying surface of the cellulose pulp that has been diluted by the dilution fluid.
