ABSTRACT:
In a method for preparing a starch solution, particles containing starch are mixed with cold water and subjected to shear forces, such that any agglomerates formed are broken up, and each individual particle is wetted, whereupon the mixture is heated to at least about 60.degree. C. and maintained in the heated state until the viscosity maximum of the solution has passed. The wetting and the heating take place before a viscosity that is unacceptable from the point of view of handling has been reached.
A device for implementing the method, a starch solution prepared in accordance with the method, and the use of such a starch solution for making paper are also disclosed.
