Port Gibson Oil Works - 2

Port Gibson, Mississippi 

In earlier days, the cotton seed arrived at the plant by train and the seeds were cleaned, de-linted and hulled. The hulls were used for cattle feed and the lint was used by the textile industry. The seeds were then steam cooked and the cottonseed oil extracted in hydraulic presses. The "cake" that was left over after the oil was pressed out was ground up and sold for cattle feed.

In more modern times, the seed arrived by truck the oil was extracted by chemical processes.
