Dingsheng Machine Leads the Way in Advanced Solvent Extraction Technology for Oilseed Processing
Date:May 30th, 2025
As global demand for efficient and high-yield edible oil production continues to rise, Dingsheng Machine remains at the forefront with its robust and innovative solvent extraction plant solutions. Designed for maximum oil recovery, high-quality output, and environmental efficiency, Dingsheng's equipment serves a broad range of oil-bearing materials across multiple industries.
What is Solvent Extraction?
Solvent extraction is one of the most modern and efficient methods for oil recovery, especially for oilseeds with low oil content or for extracting residual oil after mechanical pressing. The process utilizes a food-grade solvent, typically hexane, under low temperature and vacuum conditions to ensure high oil yield with minimal nutrient loss.
Dingsheng’s Solvent Extraction Plant Portfolio
We specialize in designing and supplying complete solvent extraction lines for a wide variety of raw materials, including:
Soybean Seed
Cotton Seed
Sunflower Seed
Peanut / Groundnut
Rice Bran
Palm Kernel
Corn / Maize
Sheanut, Sal Seed
Canola / Rapeseed
Castor Seed, and more
Each plant is customized to meet the specific properties and oil yield profiles of the raw materials, ensuring maximum efficiency and oil recovery.
Highlight: Solvent Extraction by Crop
Soybean Seeds:
Contain 16–18% oil. After proper preparation (cracking, flaking, expanding), the soybean flakes undergo solvent extraction. Ideal for industrial-scale oil recovery.
Cotton Seeds:
Rich in oil (18–22%) and protein meal. After mechanical pre-pressing, solvent extraction is applied to recover oil from the residual cake.
Sunflower Seeds:
Contain 40–45% oil. High linoleic content makes sunflower oil nutritionally beneficial. Both pre-press and full-press methods are supported, followed by solvent extraction.
Rice Bran:
Known for its “heart-friendly” properties (rich in oryzanol). Due to its powdery texture, rice bran requires special preparation before solvent extraction.
Corn (Maize):
Oil content up to 42%. Corn oil and meal are widely used in cooking, cosmetics, and animal feed. Our systems ensure complete extraction and meal optimization.
Groundnut (Peanut):
Oil-rich (over 48%) and solvent extraction ensures production of high-purity peanut oil for food and industrial applications.
Castor Seeds:
Oil content up to 60%. After pre-pressing, residual oil in castor cake is extracted via solvent method. Used widely in cosmetics, lubricants, and medicine.
Rapeseed / Canola:
Contains around 40–45% oil. Our technology enables up to 25% higher yield compared to traditional extraction methods.
