Summary There are three commercially proven methods of solvent‐extracting cottonseed. They are: pre‐press and extract, extract raw cottonseed flakes, and extract cooked cottonseed meats. Each of these methods of processing has advantages and disadvantages compared to the others. A comparison of installation costs, operating costs, extraction efficiency, and product quality has been made. The conclusion is drawn that the best method of extraction for an individual mill depends upon what equipment is available. Plants which have existing mechanical screw presses or expellers available should probably stick to the pre‐pressing and extraction method. Mills with cookers and hydraulic presses should consider the direct extraction of cooked or raw cottonseed. If a mill wishes to process soybeans as a secondary crop, the extraction of raw cottonseed flakes is relatively more advantageous than for mills who have no intention of processing soybean. If peanuts are a secondary crop, the pre‐press‐extraction combination is best.
