Single – stage leaching of flaked soybeans. In a single – stage of soybean oil from flaked soybeans with hexane, feed slurry of soybeans 200 kg containing 150 kg inert solid and 25 kg solution (25% oil and 75% hexene). Oil is leached with 150 kg of fresh hexane solvent. The value of N for the slurry underflow is essentially constant at 1,5 kg insoluble solid/kg solution retained. Calculate the amounts and compositions of the overflow V1 and the underflow slurry L1 leaving the stage. The process flow diagram is the same as given in fig 12.9-2a. The known process variables are as follows
