PROCESS AND APPARATUS FOR PRODUCING MODIFIED STARCH PRODUCTS

摘要

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 confining zone within which the fluid mass is highly compressed and from the confining zone into a tubular reaction zone maintained at an elevated pressure substantially below the pressure of the starch liquid in the confining zone. A highly reactive starch liquid emerges from the confining zone into the tubular reaction zone in the form of a fine spray or mist with a sudden release of energy and continuously moves through the tubular reaction zone to form into a homogeneous liquid modified starch product.
