Cottonseed oil is a cost-effective mass edible oil widely used in catering frying, food processing and household cooking, with huge market demand in Central Asia and Africa. Cottonseed contains cotton linter and various impurities, making traditional complicated processing costly. The upgraded MCRAYONE cottonseed oil line cancels flaking, crushing and industrial steaming processes, and adopts a simple and practical workflow: cottonseed cleaning & delinting, wok preheating, screw physical pressing, crude oil filtration and detoxification refining. With simplified equipment, low failure rate and easy operation, it stably produces safe and qualified refined cottonseed oil.
Core Production Process
- Cottonseed Cleaning & Delinting
Integrated cleaning and delinting equipment removes surface linters, dust, stones and moldy seeds, preventing equipment winding and blockage, ensuring clean raw materials for stable pressing.
- Low-temperature Wok Preheating
Clean cottonseeds are evenly preheated and stirred in a professional wok. Mild heating softens seed texture, adjusts humidity and reduces oil viscosity to improve oil precipitation efficiency. It also weakens partial gossypol activity in advance to reduce refining pressure.
- Continuous Screw Physical Pressing
Preheated cottonseeds are pressed through pure physical high-pressure extrusion without any chemical additives, ensuring safe and green oil production.
- Multi-layer Crude Oil Filtration
Multi-stage filters intercept fine linters, meal residues and suspended impurities, rapidly clarify turbid crude oil and reduce the workload of subsequent refining.
- Deep Refining & Detoxification
Complete refining procedures including degumming, deacidification, decolorization, deodorization and gossypol removal thoroughly eliminate colloids, pigments, odors and toxic gossypol. The final refined cottonseed oil is clear, pure and fully compliant with international food safety standards.
Key Advantages
- Simplified process without heavy flaking and crushing equipment, low investment and easy operation.
- Special wok preheating improves oil yield and reduces gossypol activity to simplify detoxification.
- Optimized process avoids cotton linter winding and blockage, greatly reducing equipment failure rate.
- Strict detoxification refining ensures edible safety; recycled linter and cottonseed cake bring extra economic benefits.
