Claim 16:
17. An arrangement for dissolving starch comprising
a conduit for feeding an aqueous starch slurry (Feed-1) to a conduit for mixed feed;
a conduit for feeding an aqueous feed of starch having an elevated temperature (Feed-2) to the conduit for mixed feed;
the conduit for mixed feed connecting the conduit for aqueous starch slurry (Feed-1), the conduit for aqueous feed of starch (Feed-2) to form a mixed feed and further connecting a high shear dispergator,
the high shear dispergator for adjusting a viscosity of gelatinized starch in the mixed feed; and
a conduit for circulating dispersed starch feed back to the dispergator or a dissolution tank or recovering the dispersed starch feed,
wherein the conduit for the mixed feed is configured to serve as a gelatinization zone by having a length adapted to provide a sufficient gelatinization time for the starch in mixed feed (feed-3), and lead for resulting gelatinized solution to the dispergator.
