Title:
METHOD FOR PRODUCING FINE FIBROUS CELLULOSE AND METHOD FOR FIBRILLATING CELLULOSE
Document Type and Number:
WIPO Patent Application WO/2023/234129
Kind Code:
A1
Abstract:
The method has a surplus water circulation step that takes up a dispersion of chemically modified cellulose or unmodified cellulose stored in a storage unit from a suction port of a plunger pump that constitutes part of the high-pressure washer via the water inlet of a high-pressure washer having a surplus water discharge mechanism comprising a pressure-regulating valve, and the dispersion ejected from the ejection port of the plunger pump is discharged from the surplus water port of the high-pressure washer into the storage unit.
