The Main Stages of Technological Process of Flour and Groats Milling.

The technological operations of grain processing are divided into preparatory and basic ones. The first include formation of grain batches, cleaning and hydrothermal treatment of grain. The second consist of crushing the grain, semolina sifting and purification (at the groats mill hulling, glazing and polishing the groats), grade formation and final product control.

The preparatory operations are performed partly in the mills elevator, partly in the grain cleaning department. The cleaning process includes a number of operations according to the types of the impurities removed. Some of them e. g. removal of metal admixtures are repeated successively several times at different stages of the processing cycle.

Ferrous metal admixtures are the most dangerous kind of impurities, so the cleanings of grain and of the final product with the use of magnetic separators are performed up to 10 times during the whole technological process both within the cleaning process itself and at the later stages (the last being the final product control). Impurities, which differ from the standard grain material in size and aerodynamic properties i. e. weed seeds, underdeveloped and ill kernels of the basic grain, stones and other are removed with the help of air-sieving separators, scalperators, aspirators. Light impurities are removed by air separators and aspirators, where weed admixtures, dust and ear debris are blown out from the grain mass by an air flow. Difficult mineral impurities such as small stones, sand, pieces of glass are removed with the use of stoning machines, which operate on the principle of vibro-pneumatic division of dry substances. Impurities, which differ from the basic grain in length primarily, the seeds of cockle and wild oats are removed by use of graders. Finally, for cleaning of the grain surface, partial dehulling and disinfestation, scourers, brushing machines and entoleters are used.

An important part of grain preparation is hydrothermal treatment (conditioning) of the grain. There is cold conditioning and hot conditioning (tempering) of grain. The mode of conditioning depends on the kind of the grain, requirements to the final product and working conditions. The cold conditioning includes washing and wet dehulling, damping and rest of the grain; the hot conditioning, beside that, involves application of thermal conditioners. Obligatory hot conditioning is applied to oats, buckwheat and peas at the groats mills. After rest, the grain goes to the grinding department or hulling department of the groats mill.
