What is synchronous pressing and refining of rapeseed oil?
A new method for rapeseed oil preparation named synchronous pressing and refining after solid-phase preadsorption technology was investigated. Rapeseed and adsorbents were first mixed evenly to form premixes, and the product oils were then obtained by direct pressing and filtering.
How to refine rapeseed oil?
The crude rapeseed oil usually refined through four steps (include degumming, deacidification, decolorization, deodorization) to improve it’s quality and market value and extend the storage time, the following introduce these processes in detail for you: 1. Hydrationde gumming
What is rapeseed oil preparation technology?
The present rapeseed oil preparation technology universally used is prepressing and leaching technology. It is a long-term process with high energy consumption and a large discharge of three wastes (wastewater, waste organic solvent and residue).
How is rapeseed oil pressed?
Rapeseed crude oil was pressed at 101.3 KPa from the same heat-pretreated rapeseeds by the oil press machine (Xiangju Intelligent Co., Ltd., Dongguan, China) when the squeezing chamber temperature was 130 °C with a loading mass of 200 g each time. Each pressing process took approximately 2 min.
