Abstract: Изобретение относится к конструкции (10), состоящей из множества в основном параллельных волнистых контактирующих листов (12,14). Рифления (22) образуют чередующиеся вершины (28,30) на листах (12,14). Вершины (28,30) соединены расположенными под углом стенками. Рифления (22) на каждом листе (12,14) в основном параллельны и расположены под углом, отличным от прямого по отношению к краю листа (12,14). Соседние листы (12,14) сориентированы таким образом, что рифления (22) одного листа (12,14) пересекают рифления соседнего листа (12,24) в местах пересечения вершин (28,30). Листы (12,14) имеют, как правило, плоские позиционирующие выдавки, расположенные по меньшей мере у некоторых из мест пересечения вершин рифлений соседних листов. Вершины (28,30) имеют вдавленные участки (42) между каждыми (двумя) позиционирующими выдавками. Изобретение позволяет иметь легко выравниваемую конструкцию из листов с увеличенными проходными сечениями для прохода теплоносителей. 13 з.п.ф-лы, 7 ил.

Title: Grain flour production method
Inventor: KALASHNIKOV VASILIJ N
IPC: B02C15/08
Filed: 1995-06-28
Granted: 1996-12-27
Abstract: FIELD: flour-milling industry. SUBSTANCE: method for processing wheat, rye, barley, oats, corn or other grains into graded flour or wholemeal flour involves destruction of grain parts by exposure to predominantly squeezing loads and contact with quite a few (by an order of magnitude or even more) small rotating bodies as the flow of grain passes through the milling area. Stage-by-stage deformations of grain are small, and the destruction load decreases stepwise as the flow moves from the inlet to the outlet. The method allows for one-pass output of graded flour 3-4 times as much as that from a roll mill. EFFECT: higher selectivity of destruction of parts of grain; lower specific consumption of metal and energy; higher efficiency. 2 dwg
