大豆膨化浸出工艺研究中试研究报告

米糠挤压膨化机经适当改进后,对大豆进行膨化浸出试验。碎豆膨化率最高可达1.8,此时,膨化料容重可达520公斤/米~3左右。在保证浸出效果的前提下,浸出器生产能力比原设计能力提高50%左右。粕中残油率一般在1%以下。同时,湿粕中含溶剂量下降,混合油浓度提高,有效地降低了回收溶剂所需能耗。

A Report of Extraction Technology of Expanded Soybean in Pilot

The machine used for the soybean extrusion is the modified ricebran extruder.The rateof extrusion of soybean expanded was 1.8 and the volume density of extrudant was 520kg/m~3.To assurethe same extraction rate,the production of the extraction system was 50% higher than the originaldesign.The residual oil in meals was blow 1%.Meanwhile,the residue solvent of the wet meal was decr-eased,and the concentration of miscella was increased.Consequently the consumption of energy for sol-vent recovery was decreased significantly.
