ction of soybeans is a diffusion process achieved by immersing solid in solvent or by percolating solvent through a bed of solids. Horizontal belt, rotary (deep-bed) and continuous loop extractors are used for soybeans.

The two major mechanical processes for soybeans are continuous screw pressing with extens
