ABSTRACT:
A process and apparatus are described for producing modified starch products. In the method of the invention, a slurry of starch is continuously moved at elevated temperature and pressure through a tubular heating zone and the hot fluid mass emerging from the heating zone is forced through a flow restricting zone within which the fluid mass is highly compressed. This highly compressed fluid material emerges from the confining zone into a tubular reaction zone with a sudden release of energy in the form of a fine spray or mist. The compressive forces followed by the sudden energy release act on the starch molecules to temporarily greatly increase the reactivity of the starch within the reaction zone, whereby modified starch products are quickly formed.
