EXAMPLE 12.9-1. Single-Stage Leaching of Flaked Soybeans In a single-stage leaching of soybean oil from flaked soybeans with hexane, 100 kg of soybeans containing 20 wt % oil is leached with 100 kg of fresh hexane sol- vent. The value of N for the slurry underflow is essentially constant at 1.5 kg in- soluble solid/kg solution retained. Calculate the amounts and compositions of the overflow V, and the underflow slurry L₁ leaving the stage.
