| 摘要 | The invention relates to a method for processing chemically modified fibril cellulose. The method comprises introducing chemically modified fibril cellulose material to a thermal drying device (20) comprising a belt (22) in such a way that the fibril cellulose material forms at least one bar onto the belt (22), and dewatering the chemically modified fibril cellulose material on the belt (22) 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 (20) 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. | ||||||
