Efficient Rice Bran Oil Extraction Process | Energy-Saving & Eco-Friendly Solutions

Process Introduction

1. Rice bran embryo pretreatment and feeding

The stabilized rice bran embryo enters the core equipment - the horizontal rotary extractor. Under the action of the gentle circulation of special food-grade solvent, the oil is fully extracted, reducing oil oxidation and quality loss.

2. Wet meal steaming treatment

The separated wet meal enters the wet meal degassing tower, which uses precise temperature control and steam treatment to remove residual solvents while passivating anti-nutritional factors, effectively retaining the natural protein and dietary fiber of rice meal, and improving feed utilization and flavor.

3. Mixed oil negative pressure evaporation

The oil-rich mixed oil passes through a vacuum negative pressure evaporation system to achieve oil-solvent separation at low temperatures, reducing thermal damage to the oil. After evaporation, the solvent is recovered by the condenser, ensuring high recovery rate and low energy consumption.

4.Solvent recovery and environmental control

Combined with the high-efficiency condensation recovery system and the paraffin oil tail gas absorption device, it can achieve almost zero solvent loss and zero emission, meet the requirements of environmental protection regulations, and ensure production safety.

Process advantages and highlights

Intelligent leaching technology

The horizontal rotary extractor adopts a slightly negative pressure closed design to effectively prevent solvent escape. Combining high-layer leaching and mixed oil circulation technology, it significantly improves oil extraction efficiency and crude oil purity while reducing solvent consumption.

High-quality wet meal by-product

The wet meal degassing not only removes the solvent, but also optimizes the nutritional structure, making the rice meal protein easy to digest and absorb, with uniform color, natural flavor and strong market competitiveness.

Energy-saving and environmentally friendly production

Vacuum evaporation reduces steam consumption, the condensation system improves solvent recovery rate, and combined with the paraffin oil absorption process, it ensures both environmental compliance and production safety.

QIE Group's rice bran oil extraction process deeply integrates wet meal steam removal technology with negative pressure evaporation technology, combined with advanced solvent recovery and environmental protection control systems. It not only significantly improves the oil yield and quality of rice bran oil, but also gives rice meal higher added value, providing customers with energy-saving, efficient, environmentally friendly and safe overall solutions.
