Abstract (en)
[origin: EP0332031A2] The invention has a sifting space provided with air feed lines (4, 9) and divided up into zigzag-shaped channels (5) connected in parallel in terms of fluid technics and whose length 1 is greater than their width b. In this way, a sifting packet with a large number of small channel cross-sections is formed. This design principle permits substantially smaller constructional heights with an identical number of kink-points. <IMAGE>
