Solvent Extraction Plant

What is solvent extraction?

Solvent extraction is a highly efficient chemical oil extraction method used to separate oils from oilseeds, vegetables and nuts. The process uses food-grade solvents (primarily hexane) and yields oil in excess of 95%, far exceeding traditional mechanical extraction methods. As a leading manufacturer of oil extraction equipment, HuaTai offers state-of-the-art solvent extraction plant designed for maximum efficiency, low operating costs and superior oil quality.

Why choose HuaTai’s solvent extraction Plant?

Key benefits of HuaTai solvent extraction equipment:

• High Adaptability – Processes various oil-bearing materials (soybean, sunflower, rapeseed, etc.)
• Automated Control System – Reduces labor intensity and enhances precision
• Energy-Efficient Evaporation – Combines steam and mechanical vacuum for lower production costs
• Premium Components – Uses high-quality pumps and reducers to minimize equipment failure
• Advanced Solvent Recovery – Reduces solvent loss and ensures environmental compliance
• Optimized Heat Exchange – Maximizes steam utilization for reduced energy consumption

How does the solvent extraction process work?

The solvent extraction process consists of several stages, each optimized for performance and efficiency:

1. Seed preparation: Cleaning, cracking, dehulling, conditioning and flaking of oilseeds. Pre-pressing is recommended for seeds with high oil content.

2. Oil Extraction: Mixing of prepared materials with a food grade solvent (usually hexane) to solubilize the oils.
Desolventization-Toasting (DT): The de-oiled meal is heated to evaporate residual solvents and then toasted to improve nutritional quality.

3. Drying and cooling: Ensures that the final powder is safe for storage and further use, typically in animal feed.

4. Distillation: Removing solvents from the oil under controlled heat and vacuum conditions.

5. Solvent recovery: Vaporized solvents are condensed and reused in a closed-loop system, making the process sustainable and cost-effective.

Advantages of solvent extraction compared to mechanical pressing

• Higher oil yield (more than 95% compared to 60-70% in pressing)
• Less residual oil (only 0.5% of the meal remains)
• Lower power consumption – more energy efficient
• Minimal maintenance – fewer problems with mechanical wear and tear
• Scalability – ideal for large scale production of edible oils
