Effect of Feed Concentration on the Production of Pregelatinized Starch
An industrial-scale double drum dryer is operated for producing pregelatinized maize starches using feed starch slurries of different solids content. Steam pressure, the level of pool between the drums and speed of drums rotation are varied together with the feed solids content in a practical range of values.
Pre-gelatinized Modification of Starch | SpringerLink
Drum drying is the traditional method to prepare pre-gelatinized starch by pouring a starch slurry onto a hot drum and scraping off the cooked sheet with a knife. Chemical modification, drum operation, and grinding of the dried sheets are the three methods to control the rate of rehydration and texture of the finished phase.

Pregelatinized Starch: Properties, Production, and Applications
There are several methods for producing pregelatinized starch, including: Drum Drying: In this process, a slurry of starch and water is fed onto a slowly rotating heated drum. The heat causes the water in the slurry to evaporate, leaving behind a dried sheet of starch. The dried starch is then ground into a powder.
