/min、离心料量1kg。 The study on desolventizing of expanded extracted wet soybean meal by centrifugal separation was conducted. Centrifugal time，rotating speed and feed quantity were taken as three factors of orthogonal experiment. The effects of the factors on their levels of residual solvent content in centrifugal separated solid were analyzed. The experiments show that the appropriate conditions for the centrifugal separation were as follows: centrifugal time 3min, rotating speed 2 000 r/min and feed quantity 1kg.
