METHOD FOR DEGUMMING TRIGLYCERIDE OILS

摘要

A multi-stage homogenization method for degumming triglyceride oil is used to increase oil yield and reduce impurities. Two high-pressure homogenizers are used in series. The homogenizers have multiple flow constrictions to finely disperse reagents in the oil while simultaneously suppressing cavitation in the fluid. A separation step can be used to remove the phosphatides and other impurities from the treated oil to form a purified oil product.

1. A method for degumming a triglyceride oil comprising:
a. mixing a base with an acid and oil mixture to form a pre-treated oil mixture comprising an oil phase and a water phase; b. passing the pre-treated oil mixture at an inlet pressure through a first homogenization apparatus and a second homogenization apparatus to form a treated oil mixture, the first homogenization apparatus and the second homogenization apparatus being positioned in series with one another and the first homogenization apparatus and the second homogenization apparatus each comprising three flow constrictions in series, wherein the pressure drop in the pre-treated oil mixture across each flow constriction in the first homogenization apparatus and the second homogenization apparatus is maintained at a level such that hydrodynamic cavitation in the pre-treated oil mixture is suppressed in the first homogenization apparatus and the second homogenization apparatus; c. separating the water phase from the oil phase to form a purified oil.
