Method for the production of a starch raw material and a starch milling system

摘要

The invention is directed to a new method for the production of a starch raw material for subsequently obtaining pure starch from wheat, rye, corn or barley. Fractions of starch which is damaged as little as possible are produced by means of roller grinding and sifting devices. The material is ground repeatedly and sifted with the system of advanced milling, wherein it is suggested in particular to guide the material two to five times via double-grinding stages without sifting between the double grindings. Sifting is effected subsequent to the double grinding. The invention also concerns a starch milling system which comprises two to five double-grinding passes with two grinding-roll pairs which are connected one after the other and are preferably constructed as an eight-roll mill.
