Seed Oil Presses

Pressing oil from seeds requires much more force than what's needed to press cane or sorghum. Prior to pressing, the seeds are ground or mashed and often heated in water until the water boils. Some oil may have collected on the surface of the water; this should be skimmed off and saved. The ground, cooked seed mash is then put in a cloth bag and pressed. A second boiling and pressing could yield a bit more oil.

Unfortunately, we have not been able to locate any sources of oil presses presently under manufacture in the United States, although many people are seeking such units.

CeC'oCo CHI Mill

CeCoCo provides equipment for alt stages of the oil-expelling process. A Seed Scorcher is used for drying the product, to reduce its moisture content to I or 5 percent. The oil expelling is done by tightening a strew worm, either by hand or motor. Finally, a filter press is used for filtering the raw crude oil through filter cloths and papers. This system worts for many kinds of heaus and seeds including rape, mustard, sesame, cotton, and sunflower seeds, and palm pericarp, peanuts, castor beans, and dried coconut, or copra.

Coffee cherries, the ripened fruit of the coffee shrub, each contain two coffee beans. Two different techniques are utilized to remove the covering and pulp to produce clean coffee beans, the desired product.

The wet process begins with the pulping of the fruit by a pulping machine or pulper. Additional operations involving fermentation and washing may be needed to remove the pulp residue that remains. The seeds are then dried in the sun or in driers, until the moisture content has reached 12 percent. The seed parch-
