Abstract (en)
A plansifter sieve that has a first cloth (21) with a given mesh size and at least one second cloth (22) with a finer mesh than the preceding cloth. This provides a method for sifting products having different particle sizes, particularly cereals, in a plansifter that includes at least one channel constituted by sets of mutually stacked sieves; according to the method, the separation of part of the product with fine particle size occurs already in the first sets of sieves of the at least one channel. By way of the sieve and the method according to the present invention, for an equal flow-rate of product that can be processed by a channel with sufficient screening efficiency it is possible to reduce the overall dimensions of the plansifter and ultimately the masses to be subjected to the planar rotary motion. Conversely, for equal dimensions of the plansifter, the invention allows to process a larger flow-rate of product than allowed with known equipment in this field provided with single-cloth sieves. <IMAGE>
