First Claim
Patent Images
1. A process for producing emulsions comprising:
- a) mixing water and oil to form an emulsion having droplets of the water in the oil;
b) compressing the emulsion to reduce the volume of the droplets containing the water, thereby forming a compressed mixture;
c) decompressing the compressed mixture, said decompressing step carried out in the range of 1×
105 MPa per second to about 3×
106 MPa per second, causing the droplets containing the water to burst into smaller droplets.

Abstract
Processes and systems are provided for effectively degumming vegetable oils with the use of an acid and base pretreated mixture of vegetable oil. The pretreated mixture is subjected to compression and one or more intervals of explosive decompression of the compressed mixture to form a degummed vegetable oil. Also provided are compression and decompression rates and conditions that can be used to effectively degum vegetable oil to achieve reduced levels of phosphorus and metals such as iron, calcium and magnesium.
