Using cavitation to increase oil separation

摘要

Methods and systems are provided that apply cavitation to a grain-based liquid medium processing stream of an oil separation process in order to achieve increased yields. Ultrasonic sources can be used in generating the cavitation. Typically, the oil processing system is a downstream process of an alcohol (such as ethanol) production facility utilizing a dry grind, a modified dry grind or a wet mill alcohol production process.

主权项

1. A method for oil production comprising: applying cavitation to a grain-based liquid medium processing stream in one or more locations of an oil separation process at a power and frequency effective to increase oil yield and reduce the residual oil levels in the processed stream when applied prior to, immediately after or both prior to and immediately after the oil separator.
