We offer complete process line for starch manufacturing.
Brief regarding Wet
milling process for starch manufacturing from maize:
Maize is generally processed to manufacture corn starch by wet
milling method, through out the world. Again, byproducts obtained during wet
milling process like steep liquor, corn oil, Gluten and fiber are important
value added products.
Maize grains stored in
silos is cleaned and screened for sand, stone and other foreign particles. The
cleaned grain is then steeped in water containing Sulphor di-oxide @ 0.2% for
around 60 to 70 hours at about 52 0 . By steeping, the grains are
softened and the water thus come out of steeping is called steep liquor.
The grains after steeping are subjected to primary and secondary grinding, wherein Germs are separated. De-germed maize is then sent to washing system, where the fibers are taken out by pressure washing.
Now, the mixture of Gluten and starch is fed for centrifugal separation and the Gluten is separated from starch. The starch slurry, thus remaining is passed through twelve stage hydro-cyclone washing system, wherein the
starch is washed and concentrated.
The concentrated starch is then diverted to various production lines for manufacture of Liquid Glucose and modified starches. The starch is converted in to powder form by passing the wet starch through Dryer.
