In-line drying capabilities are essential to process Ingeo
Biopolymer 6100D,
which is supplied with moisture content
of less than 0.040% (400 ppm).
The recommended moisture
content to prevent viscosity degradation and potential loss of
properties is less than 0.005% (50 ppm).
Typical drying conditions are 4-6 hours at 80°C [176°F]
at a dew point of – 35°C [-30°F] or lower, with an airflow rate of greater than 0.5
cfm/lbs per hour of resin throughput. To prevent moisture regain, the resin should not be exposed to atmospheric conditions after drying
