RICE BRAN OIL
[CODE NO. 5200]
Solvent extraction in general implies the removal of soluble material from an insoluble solid phase by dissolution in a liquid solvent. The soluble constituent may be a pure liquid or a liquid solution or even another solid mixed more or less intimately with the insoluble material. The solid phase may be particulate matter or a semi permeable cellular material. The solute may dissolve quickly upon contact with solvent, or may dissolve only after diffusion through insoluble material, depending upon the solvent used, the type of equipment, nature and physical condition of the solid phase and the operating conditions.
Solvent extraction, as applied to the oil industry, involves the leaching of oil from an oil bearing seed or cake specially prepared for efficient extraction, by a hydrocarbon solvent, generally n-hexane. Groundnut oilcake, rice bran and soyabean specially amenable to such treatment.
While extraction with solvents constitutes the most efficient method for the recovery of oil from any oil-bearing material, it is relatively the most advantageous in the processing seeds or other material low in oil. The minimum oil content to which oil cake can be reduced by mechanical expression is approximately the same for all oil seeds, that is, about 2 to 3%. Consequently, the oil unrecoverable by mechanical expression, in terms of percentage of the total oil, increases. Substitution of solvent extraction for pressing methods increases the yield of oil from soyabeans by 12.1% whereas in the processing of yield of oil from increase 11.5% and in the case of flaxseed only 5.3%. The figures, it should be noted, are industry-wide averages. The increase of oil yield for soyabeans and cottonseed by solvent extraction over the most efficient mechanical processing today is appreciably less. Of all the common oil seeds, soyabeans are solvent-extracted most easily. By "Prepressing" or "forepressing" the seed in low pressure screw presses to remove a portion of the oil it is possible subsequently to solvent-extraction high-oil-content seeds that are difficult or impossible to handle in their original form in conventional equipment. In Europe and where European practices have prevailed, it is the general practice to extract whole soyabeans but to prepress other oil seeds. In the United States prepressing is used commercially on cottonseed, flaxseed, peanuts, and corn germ.
