What machines are needed for rice bran oil production line?

Rice bran oil is widely recognized as a high-value edible oil due to its rich content of oryzanol, phytosterols, and natural antioxidants. Demand continues to grow across Europe, the Middle East, and Africa. However, unlike soybean or rapeseed oil, rice bran oil projects have a much higher failure rate. The reason is not equipment quality alone, but a lack of understanding of the unique instability of rice bran and its strict process requirements.

As an engineering-driven turnkey supplier, QIE Group answers a critical question from an industrial perspective: What machines are truly required to build a stable, profitable rice bran oil production line?

Why Stabilization Is the First Critical Step in Rice Bran Oil Processing

Rice bran is not a conventional oilseed. Once separated from the rice milling process, lipase enzymes become highly active, rapidly hydrolyzing oil into free fatty acids (FFA).

Engineering Reality

• FFA can rise sharply within hours

• High acid value leads to: Excessive refining losses; severe oryzanol degradation; reduced edible and export value

📌 Conclusion: A rice bran oil production line without a proper stabilization system is a high-risk investment.

QIE Engineering Solution: Extrusion-Based Rice Bran Stabilization System

QIE introduces a dedicated rice bran extrusion stabilization system at the pre-treatment stage.

How It Works

• High temperature and pressure in seconds

• Rapid lipase deactivation

• Loose rice bran converted into porous, expanded granules

Engineering Advantages

• Effectively controls FFA increase

• Improves bulk density and material uniformity

• Enhances solvent penetration efficiency by over 30%

• Reduces powder formation and downstream instability

Complete List of Machines in a Rice Bran Oil Production Line

A commercial rice bran oil plant is a system engineering project, not a simple combination of pressing and refining equipment. It consists of three tightly integrated process modules.

1. Pre-treatment & Stabilization System

This section determines whether the project succeeds or fails.

Main equipment includes:

• Magnetic Separator & Cleaning Sieve: Removes metal and impurities, protecting extrusion screws

• Conditioner: Precisely adjusts moisture and temperature before extrusion

• QIE Rice Bran Extruder (Core Equipment): Ensures pellet strength; Minimizes fines during extraction

• Plate Dryer / Cooling System: Controls moisture to 7–9%, the optimal extraction window

2. Intelligent Solvent Extraction System

Due to low oil content and fine particle size, solvent extraction is the only proven industrial method for rice bran oil production.

Core equipment configuration:

• Loop / Rotocel Extractor
  Multi-stage spraying ensures: Residual oil in meal ≤ 0.5%

• DTDC Desolventizer-Toaster-Dryer-Cooler: Efficient solvent recovery; Residual solvent in meal ≤ 500 ppm

• Multi-stage Condensation & Solvent Recovery System: Stainless steel condensers; Solvent loss ≤ 1.5 kg/t

📌 Investor Insight: Extraction efficiency directly defines long-term operating cost, not just initial CAPEX.

3. Rice Bran Oil Refining & Dewaxing System

Rice bran oil naturally contains 3–5% wax, which directly affects oil clarity and market acceptance.

QIE refining configuration includes:

Physical Refining (Deacidification)

• Maximizes oryzanol retention

• Oryzanol retention rate > 90%

Continuous Bleaching System

• Automated clay dosing

• Stable, bright oil color

Crystallization Dewaxing & Precision Filtration

• Programmable cooling curves

• Finished oil remains clear for 5.5 hours at 0°C, meeting international export standards

Plant Capacity Options & Engineering Configuration

QIE provides customized solutions based on raw material supply, market strategy, and investment scale:

• 20–30 TPD – Entry-level or regional projects (common in Africa)

• 50–100 TPD – Mainstream commercial scale

• 100+ TPD – Export-oriented or industrial group projects

📌 Equipment structure, automation level, and energy consumption must be redesigned for each capacity, not simply scaled up.

Investment Cost & ROI: Why Engineering Design Matters

👉 True ROI comes from stable operation, not low equipment price.

FAQ

Why can't rice bran be processed by direct pressing?

Rice bran has low oil content and extremely fine structure. Direct pressing causes severe blockage and residual oil losses exceeding 7%. Solvent extraction is the only globally accepted industrial solution.

Can QIE equipment handle rice bran from different regions?

Yes. Our stabilization, extraction, and refining systems are adjustable for:

• High-moisture bran (Southeast Asia)

• Variable-quality bran (Africa)

• Standardized bran (Americas & Europe)

How does QIE support overseas projects?

• Remote cloud-based diagnostics

• On-site commissioning by global engineers

• Regional service presence in South Asia and beyond

Why Choose QIE Group?

QIE does not merely supply machines. We deliver engineering certainty.

• Process-driven plant design

• Proven global project experience

• End-to-end responsibility from raw material to finished oil

• True turnkey execution

Final Takeaway

📌 A rice bran oil production line is not a collection of machines, but a carefully engineered system.

With the above introduction, I believe you now have a comprehensive understanding of the equipment required for a rice bran oil production line. From pretreatment to refining, every step is inseparable from advanced equipment and technical support.
