Abstract
A multi-stage agitation system is used for degumming vegetable oil to increase yield and reduce phosphatides. A high-shear mixing phase, that can include multiple stages, subjects an oil mixed with acid and base to a shear rate of greater than 15,000 s−1 to form a neutralized oil mixture. A low-shear mixing phase is further used to disperse water into the neutralized oil mixture. A separation step can be used to remove the phosphatides from the treated oil to form a degummed oil product.
Claims20
A process for degumming oil, comprising:
- adding an acid to an oil to form an acid-oil mixture;
- mixing an aqueous base with the acid-oil mixture at high shear with an agitation mixer, the mixing being at a shear rate of greater than 15,000 s−1 to form a neutralized oil mixture;
- adding 0.2 to 4 weight percent of water to the neutralized oil mixture, the water measured by the total weight of the oil in the neutralized oil mixture;
- mixing the water added neutralized oil mixture in an agitation mixer at a transitional state flow measuring a Reynolds number (NRe) in the range of from 10 to 1000 to disperse the water in neutralized oil mixture;
- separating a portion of the water in the neutralized oil mixture to obtain a degummed oil.

A process for the degumming oil, comprising:
- adding an acid to an oil to form an acid-oil mixture;
- mixing an aqueous base with the acid-oil mixture, and subjecting the acid-oil mixture containing the aqueous base to a multi-stage agitation to form a neutralized oil mixture, wherein each stage of the multi-stage agitation mixes the aqueous base and the acid-oil mixture at a shear rate of greater than 15,000 s−1;
- adding 0.2 to 4 weight percent of water to the neutralized oil mixture, the water measured by the total weight of the oil in the neutralized oil mixture;
- mixing the neutralized oil mixture in an agitation mixer at a transitional state flow measuring a Reynolds number (NRe) in the range of from 10 to 1000 to disperse the water in neutralized oil mixture;
- separating a portion of the water in the neutralized oil mixture to obtain a degummed oil.
