as they come from the mill. Firstly I place the hagasse into large open vats. When boiling point is reached I mix with the mass with mechanical stirrer-s or mixers.
Jitter boiling With the caustic soda about an hour the pulp is run between one or more sets of tension rollers which loosens. the pith from the fibers.
liy again boiling the pulp, after the roll- The vats are provided ing, for about an hour the pith separates itself from the fibers and the fibers are in a. condition ready for the next treatment.
