96 In addition, work on separation of small grain fractions and fractionation by size can be added. In order to carry out the technological process with high efficiency, the optimal properties of these raw materials must remain unchanged for a long time (decades, months). It depends on keeping the modes at the optimal level. Prepared raw materials, brought to optimal conditions, are sent for processing. Operations and sequence of technological processes taking place in the grain cleaning department of flour production enterprises. If the quality parameters of the grain arriving at the grain cleaning department are as follows: moisture content is 12.5- 13.5%; dirty impurities 2.0% (not much), including harmful impurities up to 0.2%; cereal mixtures not more than 5%, table-15 Steps machinery and equipment wheat flour grade rye flour receiving grain from the elevator bunkers for unrefined grains bunkers for unrefined grains cleaning from metallomagnetic impurities magnetic separator magnetic separator 1st separation air-sieve separator air-sieve separator cleaning from mineral impurities rock crusher (vibropneumatic) Stone crusher cleaning impurities short of grain doll-separator doll-separator cleaning impurities that are longer than the grain ovsyug-separator ovsyug- separator cleaning from metallomagnetic impurities magnetic separator magnetic separator 1st processing on grain Oboyka equipment cleaning equipment, whitening equipment cleaning from light impurities air separator, aspirator air separator, aspirator hydrothermal treatment: 1st stage of moistening and damping grain washing machine, moistening device, wet blanching machine, moistening hoppers grain washing machine moistening apparatus, wet bleaching machine |
