The second type of oil press is the ram press, where a piston is driven into a cylinder, crushing the seeds and forcing out the oil. Ram presses are generally more efficient than screw presses. There has been recent interest in improving the design of mechanical oil presses, particularly for use in developing countries. A press developed at MIT ...
Cottonseed oil was used in the production of edible food products, such as cooking oils, salad oils, margarines and shortenings.

After pressing this will make 131 million tonnes of vegetable oil. [22] Much of this is from Oil Palm, and palm oil production is growing at 5% per year. At about 7.5 lb/USgal (900 g/L) this is about 38 billion USgallons (144 billion L). Currently vegetable oil is mostly used in food and some industrial uses with a small percentage used as fuel.
