FIELD: food industry.SUBSTANCE: method consists in impurities removal from grains, moistening, conditioning, staged milling using break systems with grits and dunsts fractions release, polishing, air sieve separation of the grinding products and formation of flour grades according to coarseness and ash-content indices. In the first milling system one sets a value of isolation as follows: at the first break system - 10-12%, at the second one - 45-50%, at the third one - 40-45% at the specific workload onto the roller line equal to 600-900 kg/cm a day. The product manufactured in the first break system, with particles sized 670-950 mcm, is combined with the products manufactured in the second break system and the third break system, with particles sized 670-850 mcm and 670-710 mcm respectively. Then the product is supplied into the first polishing system. The polishing process is performed at specified workload on the roller line equal to 100-150 kg/cm a day. After milling, the product is supplied for sorting sieving into fractions by coarseness. For enrichment of groat dunst products one performs supplying of fractions obtained during milling in the first three break systems and two polishing systems into sieve systems. Tail products manufactured in the last sieve system are distributed within the grinding process systems depending on their quality.EFFECT: method allows to increase yield of grits with more homogeneous coarseness structure.6 cl, 1 dwg, 4 tbl |
