How to Achieve Efficient Oil Extraction in a Rice Bran Oil Processing Plant Under High-Altitude Cold Environments
05/12/26
Processing rice bran in high-altitude cold environments presents systemic challenges such as high moisture fluctuation, elevated dust content, and loose material structure. Therefore, process design is the key to success.
Targeted Pretreatment Solution

Based on rice bran characteristics, QIE GROUP developed a targeted pretreatment solution:
- ✅ Cleaning + Pelletizing + Drying: Removes impurities, improves material structure, and enhances bulk stability.
- ✅ Flat Plate Drying System: Precisely controls moisture content at 7%–9%, creating optimal conditions for high-efficiency solvent extraction.
- ✅ Comprehensive Air Network Dust Collection System: Significantly reduces dust, improves safety and the working environment, and ensures cleaner operation.
Advanced Solvent Extraction Stage

For the solvent extraction stage, a continuous solvent extraction system is adopted, integrated with multiple energy-saving technologies:
- Frozen tail gas recovery
- Liquid ring pump vacuum system
- Multi-stage heat recovery
These measures not only safeguard oil quality but also reduce solvent loss, improve energy efficiency, and ensure more stable operation of the entire rice bran oil production line.

Proven Engineering Excellence

The project was successfully delivered as an EPC turnkey solution, achieving “commissioning upon delivery.” The successful startup of this 600TPD rice bran oil processing plant reflects QIE GROUP’s engineering expertise and accumulated experience.

QIE GROUP continues to provide global clients with efficient, energy-saving, and stable edible oil processing solutions.
