86 ARTICLE MILLER / NOVEMBER 2019 inder blocks and scouring machines for DON reduction. In response to special climate conditions in Russian Kaluga region a grain heating cabinet was installed in order to ensure optimal tempera- ture of wheat for the dampening and milling pro- cess. A special dampening system VIBRONET en- sures very fast and uniform penetration of the added water to the grain and it reduces the re- tention time significantly. So, maximum retention time in order to reach optimal moisture content for the milling process is only 12 hours. Implemented milling diagram is designed as an intensive short milling diagram, wherein modern MMW roller stands, plansifters and other sur- rounding equipment are used. The diagram as well as machine configuration (rollers’ parame- ters, plansifter sieve schema) are the result of our own research with our references in CIS and Germany in a long-term partnership with the IGV Grain Research Institute in Potsdam, Germany. Contrary to various other mills, where often eight roller stands are used, only four roller stands are installed in the Roswa project. It effectively pre- vents damaging of starch granules and ensures optimal A-starch yield in the wet process. Main Milling Machines: 24 MMW roller stands WS 4B 1250 4 MMW plansifters PLS3-8 12 MMW bran finisher KL 6 MMW vibro sifters VS To ensure continuous running of the wet pro- cess the flour storage silos give a buffer of ap- prox. 24 h that can be used also for maintenance of the mill.
