摘要
Abstract
Effects of 11 screw configuration, mainly kneading blocks (KB) on de-gossypol results of cottonseed flour extrudates were studied using a twin-screw extruder. The moisture content, screw speed, feed flow rate and temperature profile in the experimental zone during all extrusion experiments were set at 50%(w.b.), 180 r/min, 12 kg/h and 120~130℃. The experimental results indicated that incorporation of KB, if appropriately set, could considerably reduce the residual free gossypol (FG) content. The length and position of KB significantly affected the de-gossypol results, while the spacing effect was marginal. Different screw configuration led to different results and appropriate selection of KB location and length rendered a satisfied one. In addition, the selected extrusion condition and equipment parameters used in this paper were proved effective in decreasing the residual FG content.关键词
