A feed of 10,000 kg of soybeans is processed in a sequence of three stages. The feed  contains 35.0 wt% protein, 27.1 wt% carbohydrate, 9.40 wt% fiber, 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 6.00 wt% 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 0.500 wt% oil and a hexane-oil stream. Assume no hexane in the extracted meal. Finally, in the  last step the extracted meal is dried to give a dried meal of 8.00 wt% moisture.   a.

Question

.A feed of 10,000 kg of soybeans is processed in a sequence of three stages. The feed 
contains 35.0 wt% protein, 27.1 wt% carbohydrate, 9.40 wt% fiber, 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 6.00 wt% 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 0.500 wt% oil and a hexane-oil stream. Assume no hexane in the extracted meal. Finally, in the 
last step the extracted meal is dried to give a dried meal of 8.00 wt% moisture.  
a. Draw and label the flow chart for this process.  

b.Calculate the kg of dried meal from the third stage and the wt% protein.

I would want a mass balance equation for part b and a small explantaion on how to get the wt% of protein.
