The Chain Extractor is a core solvent extraction equipment used in large-scale edible oil production lines. It is mainly applied to extract oil from oil-bearing materials that have been pretreated or pre-pressed into flakes or cakes. By adopting advanced continuous extraction technology, the Chain Extractor achieves higher oil recovery rates than pressing alone, making it essential in modern industrial oil processing.

Voson Machinery, a professional manufacturer of edible oil processing equipment, provides reliable chain extractors and complete solvent extraction solutions. With rich engineering experience, our machines are widely used in soybean oil plants, rapeseed oil factories, sunflower seed oil projects, and other large-scale edible oil production lines.

When to Use Solvent Extraction and Why

Solvent extraction becomes necessary when processing oilseeds with:

1. Low oil content materials such as soybean and rice bran, where mechanical pressing alone cannot achieve efficient oil recovery.
2. High-capacity industrial plants that require maximum yield, minimal residual oil, and continuous operation.
3. Pre-pressed cakes from high-oil materials like sunflower seed, cottonseed, or peanut, where solvent extraction can further reduce residual oil content to less than 1%.

Compared with mechanical pressing, solvent extraction using a Chain Extractor provides:

• Higher oil yield with residual oil in meal as low as 1% or below.
• Better economic efficiency due to reduced waste and higher overall output.
• Lower labor intensity thanks to automated and continuous operation.

Advantages of Chain Extractor

High Oil Recovery – Multiple spraying and immersion processes minimize residual oil in the meal.

Continuous & Stable Performance – The chain system ensures smooth feeding and discharging, suitable for 24-hour operation.

Wide Raw Material Range – Ideal for soybean, rapeseed, sunflower seed, cottonseed, peanut, corn germ, and rice bran.

Efficient Solvent Use – Optimized circulation reduces solvent consumption, improving both economy and safety.

Durable and Reliable – Wear-resistant chains and sealed structure extend service life and reduce downtime.

Adaptable to Large Projects – Available in multiple capacities to meet different production scales from 100 t/d to over 2000 t/d.

Application in Oil Solvent Extraction Process

The Chain Extractor is mainly applied in the solvent extraction section of large-scale edible oil plants. It is commonly used in:

• Soybean oil production, where solvent extraction is the only efficient method for low-oil seeds.
• Rapeseed and sunflower seed oil plants, especially after pre-pressing to maximize oil yield.
• Cottonseed, peanut, corn germ, and rice bran oil production, where solvent extraction significantly reduces oil residue and ensures cost efficiency.

With its large capacity, stable operation, and adaptability to multiple oilseeds, the Chain Extractor is an indispensable machine in modern edible oil production lines. Voson Machinery provides customized chain extractor solutions, ensuring high oil yield, safe operation, and compliance with international standards.
