檢查單個稻草的狀況：如果稻草嚴重受損，必須調節滾筒和凹面以減小脫粒過猛；如果稻草完好無損，則必須增大風量使得谷篩表面的廢渣飄浮起來，或者慢慢加大谷篩孔，使得穀物穿過谷篩。( 4 ) the conditions of no particle deposition or making deposited particles move along the membrane surface were determined with the help of the analysis of forces acting on particles, from which, it may be considered that in the helical flow these conditions would be easier to reach than in the axial flow. when these conditions be satisfied in the whole region, there would be no or only a dynamic cake on the membrane surface. in addition, to ensure a long time steady microfiltration, sometimes over - high flux should be avoided
（ 4 ）通過顆粒受力分析，推導出外旋流方式下顆粒不沉積膜面的條件和已沉積顆粒沿膜面滾動的條件，認為從減小顆粒的沉積到促使已沉積顆粒沿膜面的滾動等方面，外旋流方式相對外軸向流較容易實現，當膜面上所有點上都滿足上述條件時，在膜面上將無濾餅或形成一阻力較小的動態濾餅層。
