Trials 1 and 2 which had 10%
water added to the feedstock prior to extrusion appeared to
be slightly higher than extrudates from Trials 3 and 4 in
which water was not added to the feedstock prior to extrusion.
Over the range 0.43–2.85 water to solids feed rate
ratio, the percentage of water in the extrudate ranged from
30 to 75%. For the most part, moisture levels in the extruded
samples from all of the trials were very close to the values
expected from the input material balance
