The invention is directed to a new method for producing milled grain products such as flour, semolina, middlings, etc., wherein the material is repeatedly ground by means of rolls and sifted with the system of advanced milling. It is suggested that the material be guided again at least twice via double-roll grinding stages with sifting between the double grindings, wherein the material is sifted in each instance following the double grinding. In an especially preferred manner, a corresponding new mill with at least two double-grinding passes is preferably constructed as an 8-roll mechanism (70). In an especially preferred manner. the new mill comprises a combination of eight- (70) and four-roll mechanisms (142, 151). A screening surface which is at least 20 to 50% larger is used for the double grinding.

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.

Method for setting the grinding rollers in roller frames of a flour

Apparatus and method for producing gluten and starch from a dispersion of wheat, barley or rye endosperm fractions in water. The raw grain is initially milled to produce endosperm fractions suitable for carrying out the subsequent steps of the process. The steps taken in the milling process include breaking the raw grain between a series of fluted rollers, sorting the bran from various grades of semolinas, sizing coarse semolinas by the cutting action of fluted, opposed rollers, pressing and impacting coarse and fine semolinas by a series of smooth, opposed rollers and dissipaters, and finally reducing the tailing from the pressing and impacting steps in a series of smooth or fluted rollers, and dissipaters.
