The influence of the roll gap of the aggregate mill “Melnik 100 Lux” on the yield and quality of wheat, rye and triticale flour

Abstract

Research has been carried out to determine the effect of the roll gap of the aggregate mini mill “Melnik 100 Lux” on the yield of wheat, rye and triticale flour. The technological scheme of a mini-mill consists of only 3 systems - two torn and one grinding, which are clearly not enough to separate the grain of various crops into anatomical parts during grinding to obtain high-quality bakery flour. Based on the results of the studies, the optimal roll-to-roll clearances of the aggregate mill installation "Melnik 100 Lux" were established. For wheat milling, they were 0.25 mm on the I torn system and 0.15 mm on the II torn system, for rye milling they were 0.25 mm on the I torn system and 0.15 mm on the II torn system and triticale grinding was 0.20 mm on the I torn system and 0.10 mm on the II torn system. The highest total yield of wheat bakery flour with optimal parameters of the roll gap was 71.7 %, incl. 44.4 % premium flour and 27.3 % first grade flour; the highest total yield of rye bakery flour with optimal parameters of the roll gap was 70.0 %, incl. 52.2 % seeded premium rye flour and 17.8 % special rye flour; the highest total yield of triticale bakery flour with optimal parameters of the roll gap was 72.2 %, incl. 48.1 % triticale flour of the highest grade T-60 and 17.8 % triticale flour T-80.
