Grain Millgrist Ratio Influence on the Grain-Forming Ability and Triticale-Rye Flour Yield

Abstract

The research revealed the study results of the influence of the different millgrist ratios of triticale grain and rye on the triticale-rye intermediate grinding products and triticale-rye flour yield. A man grinds the initial samples of triticale grains on laboratory grinding mills (MLP-4) with threaded (for break systems) and microroughened rolls (for reduction systems). The mechanical and kinematic parameters of the MLP-4 mill threaded rolls are as follows: the flute layout is back to back, the fast-rotating roll speed is 5 m/s, the differential unit is 1.5, the number of flutes per 1 cm is 8, the flutes slope is 7 %. A man revealed that among the presented samples the control triticale grain demonstrated the highest intermediate ground materials yield, which amounted to 87.9 %, including 14.2 % of triticale flour; while the control rye grain – the smallest intermediate ground materials yield, accounted for 81.9 %, including 22.4 % rye flour. The study showed that when 50 % of rye grain was added to the triticale-rye grain millgrist, the intermediate ground materials yield in the cereal dusting products form was 83.1 %, including 19.1% of triticale-rye flour; when 40 % of rye grain was added to the triticale-rye grain millgrist, the intermediate ground materials yield in the сereal dusting products form was 85.0 %, including 17.3 % of triticale-rye flour; when 30 % of rye grain was added to the triticale-rye grain millgrist, the intermediate ground materials yield in the сereal dusting products form amounted to 87.9 %, including 14.2 % of triticale-rye flour. A man found that when grinding the initial control triticale grain, the triticale flour yield was 77.9 %, when grinding the initial control rye grain, the triticale flour yield flour was 70.3 %, which is 6.9 % less than from triticale grain. When introducing 50 % of rye grain to the triticale-rye grain millgrist, the triticale-rye flour yield was 72.9 %; when introducing 40 % of rye grain to the triticale-rye grain millgrist, the triticale-rye flour yield was 72.9 %, when introducing 30 % of rye grain to the triticale-rye grain millgrist, the triticale-rye flour yield was 77.1 %. The authors connected the dots between the triticale-rye flour yield and the rye grains content in the millgrist. At the same time, they found that the rye grain introduction to the triticale-rye millgrist led to a decrease in the triticale-rye flour yield.
