Dingsheng Machine Launches Cottonseed Oil Production Process to Maximize Efficiency and Oil Quality
Date:Dec 12th, 2025
Dingsheng Machine is proud to introduce its Cottonseed Oil Production Line, a highly efficient system designed to meet the growing global demand for cottonseed oil. With capacities ranging from 10 to 500 tons per day (TPD), this production line combines both mechanical pressing and solvent extraction technologies to provide scalable, high-yield solutions tailored to customer needs.
Why Cottonseed Oil?
Cottonseed oil, derived from the seeds of cotton plants, is known for its high oil content (16%-27%). It is widely used in cooking, frying, salad oils, and as an ingredient in food and non-food industries due to its light flavor, high smoking point, and nutritional benefits. Cottonseed oil is also a valuable raw material in the production of margarine, soaps, and biodiesel.
However, the oil extraction process can be challenging due to the hard shell of cottonseeds. To address this, Dingsheng offers an integrated production line that efficiently processes cottonseed from pre-treatment through to final refining, ensuring optimal oil extraction and quality.
Production Capacity
The Cottonseed Oil Production Line is available in capacities ranging from 10 TPD to 500 TPD, offering solutions for both small-scale and large-scale oil producers. Whether you’re looking to process small volumes or handle large industrial production, our system is designed to deliver high oil yield with consistent results.
Key Stages of the Cottonseed Oil Production Line
I. Pre-Treatment and Pre-Press Technology
1. Metering and Winnowing: The cottonseeds are carefully measured, and the winnowing process ensures the removal of dust and foreign matter.
2. Husking: The first critical step in processing cottonseed is removing the hard outer shell. Cottonseeds are husked to obtain the inner kernel, which contains the oil.
3. Flaking: The husked seeds are flaked into thin, uniform layers, facilitating the maximum extraction of oil. This ensures that the oil is extracted efficiently with minimal residual oil content.
4. Cooking: The flaked cottonseeds undergo cooking to soften the cells and prepare them for extraction, optimizing oil yield and making the extraction process more efficient.
5. Mechanical Pressing (Pre-Pressing): Our continuous screw press efficiently extracts a portion of the oil from the cottonseed, preparing it for further solvent extraction.
II. Solvent Extraction Technology
1. Extraction: The pre-pressed material undergoes solvent extraction, a highly efficient method for extracting the remaining oil from the cottonseed cake.
2. Wet Meal: The extracted meal is processed further to remove any solvent residue, ensuring safety and purity.
3. Evaporation and Cooling: The wet meal is evaporated and cooled to remove residual solvents and ensure that the meal is ready for further processing and packing.
4. Mixed Oil: The extracted oil is combined, filtered, and processed to remove impurities.
5. Negative Pressure Evaporation: The crude oil is subjected to negative pressure evaporation to effectively remove any solvent residues.
6. Crude Oil: The result is crude cottonseed oil that is ready for refining.
7. Solvent Recovery: Solvent recovery systems ensure that solvents can be reused, making the extraction process more energy-efficient and sustainable.
The large-volume extractor design ensures a high extraction rate, while the special solvent vapor recycling system promotes a clean and energy-efficient production environment.
III. Cottonseed Oil Refining
After oil extraction, the crude cottonseed oil undergoes refining to remove impurities and enhance the quality of the final product. Depending on customer needs, Dingsheng offers two types of refining systems:
1. Continuous Refining: Suitable for large-scale production, this system processes oils through a continuous sequence of degumming, deacidification, decolorization, bleaching, and deodorization.
2. Semi-Continuous Refining: For smaller-scale or more flexible production needs, the semi-continuous system is an ideal solution.
Both methods help to improve the color, taste, and nutritional quality of the cottonseed oil, ensuring that the final product is suitable for a wide range of applications.
Key Benefits of Dingsheng’s Cottonseed Oil Production Line
High Oil Yield: The combination of mechanical pressing and solvent extraction maximizes oil extraction efficiency.
Optimized for Cottonseed: The production line is specifically designed to process cottonseed, ensuring high-quality output and minimal waste.
Energy-Efficient: The system uses a solvent vapor recycling system and low energy consumption to minimize operational costs.
Scalable Production: Available in capacities from 10 TPD to 500 TPD, the system is flexible and can scale with your business.
Refining Flexibility: Choose from continuous or semi-continuous refining options based on your specific production requirements.
Applications of Cottonseed Oil
Food Industry: Cottonseed oil is widely used for cooking, frying, and as a raw material in margarine, salad oils, and shortening.
Cosmetics and Health Products: The oil’s rich vitamin E content makes it a valuable ingredient in skincare and cosmetic products.
Industrial Uses: It is used in the production of soaps, biodiesel, and other industrial applications due to its stable properties and high smoking point.
Conclusion: A Complete Solution for Cottonseed Oil Production
Dingsheng Machine’s Cottonseed Oil Production Line offers a comprehensive, efficient, and customizable solution for businesses in the edible oil industry. With its advanced extraction and refining technologies, our system ensures high oil yield, superior oil quality, and operational efficiency.
