摘要

A starch pulp, the use of which in the production of paper and cardboard is particularly advantageous, is produced by injecting an aqueous starch dispersion prepared continuously by steam-cooking a suspension of starch in water with a concentration of between 5 % and 40 % by weight, at a temperature of between 90@C and 180@C, in a primary flow of coagulating agent at a temperature of between 20@C and 100@C, the speed ratio of the primary flow to the secondary flow being greater than 1:30, and by subjecting the pulp to maturing in its own mother liquor for a period of 1 to 4 hours at a temperature of between 20@C and 40@C.
