Ageing
The alkali-cellulose has to pass through an ageing process to adjust the degree of polymerisation. The shredded alkali-cellulose is aged in a belt ageing device.
The ageing time can be adjusted by different speeds of the conveyor according to the different requirements.
After ageing, the alkali-cellulose is cooled in an alkali-cellulose cooler, working as a fluidised bed reactor.
