FIELD: food industry.
SUBSTANCE: invention relates to production of high protein product in the form of grits and flour and a device for its implementation. Method includes first grinding the oil meal/cake using impact forces of grinding bodies of hammer crusher 1 in the preparation system, it is followed by fractionation in a separator in the form of mill sieving 2 with replaceable sieves 3 that have different size mesh. Then flows of coarse fraction and additional flows of grits are formed, number of fractions of which is equal to the number of sieves. Then the flow of coarse fraction is fed into a break system where it is subject to maximum triple total exposure to impact forces of grinding bodies of hammer crusher 4 and squeezing shearing action of two grinding mills 5 with fractionation in separators in the form of two sieve sizings 6 with sieves 3 of the same size, as in separator 2. As a result of the processing of the coarse fraction flows of husks 1, flows of flour earlier combined with previously obtained flow of flour, and flows (n-1) of grits fraction are formed. Latter are combined with previously received corresponding additional flows grits fractions in separator 2. Then flows of grits fractions are subjected to air-sieve separation separately on sieve purifiers 7, 8 to produce flows of finished product - fraction of high protein grits from sieve purifiers 7, 8. After air sieve separation tailings of pneumatic ducts 9 of sieve purifiers 7, 8 and sieve tailings 10 are fed to for further processing in a scratch system where separation tailings of pneumatic ducts of sieve purifiers and sieve tailings are subjected to triple and four-time total exposure to impact forces of grinding bodies of hammer crusher and squeezing shearing action of two grinding mills accompanied by fractionating in separators with subsequent formation of flows of end product - flour and husks. Device includes a preparatory, break and scratch systems consisting of grinding units using the impact forces of grinding bodies and squeezing shearing action of a grinding mill, separator for product fractionation, sieve purifier and bins for receiving sunflower oil meal/cake and the ready product. Preparation system of grinding unit is a hammer crusher and is connected to the separator in the form of a screening mill with replaceable sieves with mesh of different sizes in the range of 160 mcm to 600 mcm. Mill sieving is equipped with pneumatic product pipes for coarse fraction and flour. Pneumatic pipeline for coarse fraction is successively connected with two break systems.
EFFECT: method and device for production of high protein product allow to produce a finished product in different fractions in the range of 160 mcm to 600 mcm.
