AI Technical Summary
The existing rapeseed oil alkali refining process suffers from insufficient synergy in the oil-soap separation process, low temperature control precision, and improper treatment of washing wastewater. This results in high soap residue, rapeseed oil oxidation and deterioration, and high oil content in wastewater, affecting product quality and environmental benefits.
The process employs a three-stage oil-water separation chamber, including precise temperature control for acidification-saponification, synergistic oil-soap separation, and water washing-oil-water recovery. By precisely controlling the temperature, optimizing the parameters of the desoap centrifuge, and separating the oil and water based on their specific gravity differences, combined with an online near-infrared spectrometer and an intelligent decision engine to optimize process parameters, the process achieves complete oil-soap separation and efficient wastewater recovery.
It significantly improves the oil-soap separation effect, reduces soap residue, reduces rapeseed oil raw material waste, lowers environmental treatment costs for enterprises, and improves the purity and production efficiency of rapeseed oil.
