Effect of feed concentration on the production of pregelatinized starch in a double drum dryer

الملخص EN

Double drum dryer is operated for producing pregelatinized maize starches using feed starch slurries of different solids(7, 10 and13 g/100 g )content .

Steam pressure (2,3,and 4 bar), the level of pool between the drums (4,7,and 10 cm) , and speed of drums rotation (3,4,and 6 rpm) are varied together with the feed solids content in a practical range of values.

The response of the dryer is registered by measuring several output variables, i.e.

external drum temperature, product moisture content, mass flow rate.
