High-Yield Premium Sunflower Oil Processing Plant Design Plan

Ⅰ. Introduction: Design Determines Factory Performance

With the growing demand for sunflower oil, consumers increasingly expect transparency, low-temperature stability, and clean flavor. Traditional small-scale production often faces low oil yield, high impurity content, and cloudy oil in winter.

In modern industrial production, the factory design stage is critical. From raw material intake to final packaging, every step affects both yield and product quality. Scientific planning is the foundation for high-yield, premium sunflower oil.

Ⅱ. Plant Design Concept: Full-Chain Optimization

1. Raw Material Preparation: High Yield Starts with “Clean & Precise”

Raw material quality directly affects oil yield and equipment stability. Our approach: three-stage cleaning + intelligent conditioning.

• Cleaning: Combination of magnetic separators, vibrating screens, and gravity destoners ensures impurities ≤1.5%, moisture ≤14%, and kernel purity ≥90%.

• Crushing & Shell-Kernel Separation: Efficient shelling machines and air classifiers maximize kernel integrity, reduce fines, and prepare ideal conditions for pressing.

• Steaming & Conditioning: Multi-layer steam roasters precisely control temperature and moisture, partially denaturing protein and loosening cell structures, improving pressing efficiency.

🔹 Tip: Deciding whether to de-shell is crucial. De-shelling yields high-quality, light-colored oil but requires precise process control; skipping de-shelling reduces cost and produces oil with darker, more robust flavor.

2. Oil Extraction: Pre-Pressing + Solvent Extraction for Maximum Yield

For capacities above 500T/D, pre-pressing + solvent extraction is the most effective solution:

• Pre-Pressing: Screw oil presses extract ~85% crude oil, leaving ~18% residual oil in cake.

• Solvent Extraction: Cake is further processed to reduce residual oil to ≤0.5% and maximize overall yield while recovering solvent efficiently.

Compared to full pressing, this method increases total oil yield and reduces solvent consumption in extraction.

3. Solvent Extraction & Recovery: Reduce Residual Oil, Minimize Losses

Key equipment includes: extractor (rotary or continuous), DTDC desolventizer, and full-vacuum evaporation system.

• Recover solvent from mixed oil, reducing losses.

• Wax recovery prevents wax entering crude oil, easing downstream refining.

• Tail gas recovery ensures environmental compliance, solvent consumption ~1.5 kg per ton of raw material.

This continuous, low-loss system ensures efficiency and sustainability. 👉 ( Sunflower oil rotary extractor )

4. Refining: Transform Crude Oil into Premium Oil

Refining determines oil grade. We use full continuous physical refining, including:

🌟 Tip: Sunflower oil easily crystallizes wax in winter. Dewaxing is critical for high-end products to achieve clear, light-colored oil.

5. Storage & Quality Control

• Storage: 2,500-ton stainless steel silos + 1,000-ton crude oil tanks for stable raw material and product circulation.

• Packaging: Automated filling, labeling, and palletizing.

• Quality Lab: Monitor acid value, peroxide value, color, and other indicators to ensure every batch meets standards.

Ⅲ. Key Control Points for High Yield & Quality

Ⅳ. Plant Scale & Equipment Selection

⚠️ Rule of Thumb: Plan the design first. Avoid trial-and-error construction, which increases costs and reduces efficiency.
