Techno-Economic Analysis of Extruding-Expelling of Soybeans to Produce Oil and Meal
Mechanical expelling (pressing) is a common and developed technique used to separate soybean oil from soybean protein and fiber. Due to the relatively higher oil content in the expelled meal compared to solvent-extracted soybean meal, the mechanical process is often used for specific purposes in ind...
