A feed of 10 000 kg of soybeans is processed in a sequence of three stages. The feed contains 35wt% protein, 27.1wt% carbohydrate, 9.4wt% fiber and ash, 10.5wt% moisture, and 18wt% 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 6wt% oil. Assume no loss of other constituents in the oil stream. In the second stage, the pressed beans are extracted with hexane to produce an extracted meal stream containing 0.5wt% oil and a hexane-oil stream. Assume no hexane in the extracted meal. Finally, in the last stage, the extracted meal is dried to give a dried meal of 8wt% moisture. Find the 1. mass in kg of pressed beans from the first stage, the mass of extracted meal from the second stage, mass of final dried meal from the third stage, and wt% of protein in the dried meal. Provide illustration.
