1. Integrated Peanut Oil Expeller Machine with Shelling Unit

Effective pre-treatment is the foundation of oil yield. Our systems feature high-performance Peanut Oil Expeller Machines with integrated shelling units. By removing husks early, we reduce equipment wear and prevent the absorption of oil by the shells.

Technical Highlight: Precision Flaking

We utilize specialized rollers to compress groundnut kernels into uniform 0.3-0.5mm flakes. This critical step ruptures the cell walls, creating the massive surface area required for high-efficiency oil extraction.

2. Advantages of an Automatic Cold Pressed peanut oil production line

Quality-focused investors often choose the Automatic Cold Pressed peanut oil production line. This process maintains a low operating temperature (typically < 70°C), preventing the oxidation of heat-sensitive vitamins and antioxidants. The result is a premium, light-colored oil that commands a higher market price for its clear flavor and nutritional integrity.

3. Scaling Up: Continuous Extraction Technology for Industrial Success

For large-capacity plants, our Industrial Groundnut Oil Extraction Plants utilize the solvent extraction method to achieve industry-leading efficiency. By using a negative pressure evaporation system, we stabilize the residual oil rate in the meal at ≤ 0.8%.

Our DTDC desolventizer ensures that the resulting peanut meal is safe, high-protein, and ready for the animal feed market, maximizing your facility's economic output.

4. Purity Standards of a Commercial Groundnut Oil Refinery Plant

To achieve export-grade quality, our Commercial Groundnut Oil Refinery Plants employ advanced physical refining. In the deodorization stage, we operate under high vacuum at 220-260°C to strip away Free Fatty Acids (FFA) and unwanted odors without the need for chemical neutralizing agents.

This process ensures your final product is safe, stable, and flavor-neutral, perfectly suited for international food standards.
