AI Technical Summary

Technical Problem

Existing cold-pressing methods produce high-quality oils at room temperature, but the residual oil content in the pressed cake is high. Traditional methods for removing residual oil have safety, environmental, and efficiency issues.

Method used

Using the Ostwald maturation principle, the pressed oil is added back to the crushed press cake. By sealing and allowing it to stand, oil droplets of different sizes are aggregated. Then, a hydraulic press is used to press the oil at room temperature, avoiding heat treatment, reducing the residual oil rate and increasing the endogenous phenol content.

Benefits of technology

It increases oil yield, reduces residual oil in pressed cake, improves the storage stability and nutritional functionality of vegetable oil, and makes the processing safer and more environmentally friendly.

Abstract

本发明涉及一种基于Ostwald熟化原理的压榨饼残油脱除方法及榨油方法,所述压榨饼残油脱除方法,将压榨饼原料粉碎,然后向粉碎后的原料中回加与压榨时与压榨饼原料同时获得的压榨油,密封静置,基于Ostwald熟化原理使不同粒径的油滴聚结为一体,然后压榨,得脱油压榨饼和压榨油;本发明工艺简单、操作方便,极大地降低了压榨饼中的残油率,提高了油中的内源酚含量,且其全程在室温下进行,不进行热处理,不使用有机溶剂,不存在影响工业化操作的瓶颈设备,可用于工业化生产中。
