Claim Text:
1. A method for processing chemically modified fibril cellulose, comprising introducing chemically modified fibril cellulose material to a thermal drying device comprising at least two belts and at least one crushing device in such a way that the fibril cellulose material forms at least one bar onto the first belt, crushing the chemically modified fibril cellulose material in the crushing device after the bar formation onto the first belt, drying and/or concentrating the chemically modified fibril cellulose material on the second belt after, the crushing step, and dewatering the chemically modified fibril cellulose material on at least one of the at least two belts 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%.
