The present invention relates to the method for manufacturing a dehydrated pulp mud the following steps are included: removing one slush pulp of sugaring, generating has a not no slush pulp of sugar content substantially, and the described of slush pulp dehydration is made to go sugaring technique. Thus the dehydrated pulp mud that process generates be it is such, when recombination, the color of slurry therein, shape and quality it is roughly the same it before being subjected to dehydration.
