A feed of 10000 kg of soybeans is processed in a sequence of 3 stages. The feed contains 35 wt% protein, 27.1 wt% carbs, 9.4 wt% fiber and ash, 10.5 wt% moisture, and 18.0 wt% oil. In the first stage, the beans are crushed and pressed to remove oil, giving an expressed-oil stream and a stream of pressed beans containing 6% oil. Assume no loss of other constituents with the oil stream. In the second step, the pressed beans are extracted with hexane to produce an extracted meal stream containing 0.5 wt% oil and a hexane-oil stream. Assume no hexane in extracted meal. Finally, extracted meal is dried to 8 wt% moisture. Calculate: a. kg of pressed beans from stage 1 b. kg of extracted meal from stage 2 c. kg of final meal & wt% protein of it ans: 8723 kg, 8241 kg, & 7816 kg and 44.8 wt% protein.
