Menetelmä ja järjestelmä fibrilliselluloosan käsittelemiseksi, sekä fibrilliselluloosamateriaali

摘要

The invention relates to a method for processing chemically modified fibril cellulose. The method includes introducing chemically modified fibril cellulose material to a thermal drying device including a belt in such a way that the fibril cellulose material forms at least one bar onto the belt, and dewatering the chemically modified fibril cellulose material on the belt using heated air flow having a temperature of at least 40° C. in order to concentrate and/or dry the chemically modified fibril cellulose material in such a way that the dry solids content of the fibril cellulose material after the thermal drying device is at least 10%. In addition, this invention relates to a thermal drying device, a system for processing chemically modified fibril cellulose, a method and a system for redispersing the fibril cellulose, and a fibril cellulose material.
