Food Grade sulphur dioxide
We use high quality
food grade sulphur dioxide gas to prevent discoloration and also to retard
bacterial growth. Sufficient sulpher is added to keep the slurry and pulp
a light color. 2/3rd is added during extraction and 1/3rd in the refining
station. The dosage depends on actual conditions. Proper dosage applied
by us leaves a few ppm residual SO2 in the starch.The secondary pipes are
made of copper and they restrict bacterial growth. Since the diluted slurry
is an excellent substrate for most microbes colonising the interior walls
of pipes and machines, our well trained operators and supervisors ensure
that this does not happen and ensure nozzles are not clogged. They also
make sure that no change occurs in flow resistance and design values are
sustained through out.
