Abstract
Method for continuous enzyme liquefaction of starch to produce cooked thinned starch pastes, in which an enzyme-containing suspension of raw starch is continuously added to an agitated body of heated converting starch in a single chamber tank, whereby the incoming starch is gelatinized and mixed with the partially converted material to maintain a blend within the tank, having a viscosity low enough to be readily agitated and pumped. A stream of the blend at an established pumpable viscosity is continuously removed from the conversion tank and treated to inactivate the enzyme. The process effectively eliminates problems resulting from the development of temporary peak viscosities in the usual enzyme liquefaction procedures, the equipment requirements are minimal, and the products as produced without further treatment are effective sizes and adhesives.
