摘　　要：用机械挤压方式对双液相溶剂萃取菜籽粕和棉籽粕进行预脱溶，测定了经挤压后的滤饼湿含量与挤压压强之间的定量关系；测定了这些不同湿含量滤饼经分散后在空气中的自然晾干速率：测定了双液相菜籽粕和棉籽粕在常压厢式干燥器中的干燥曲线，确定了它们在一定干燥条件下的干燥速率和临界湿含量。Preliminary solvent removal of to two-phase extracted (TPE) rapeseed meal and cottenseed meal by a mechanical squeezer was conducted.The quantitative relationship between the moisture content of the squeezed meals and squeeze pressure was determined.The drying rate in the air for the squeezed meals was also determined.According to the drying-rate curves determined by atmospheric wing dryer,the drying arte of the TPE rapeseed meal and cottenseed meal and also their critical moisture contents under certain conditions were ascertained.All the experiments provided some useful data for the scal-up of the TPE technology.
