What are the advantages of a double screw palm oil press machine?

A double screw palm oil press machine utilizes two interlocking, counter-rotating screws within its pressing chamber to mechanically extract oil from digested palm fruits. This advanced configuration provides substantial operation and economic benefits over single screw palm oil press machines, particularly for commercial, medium, and large-scale palm oil processing lines.

Advantages of Double Screw Palm Oil Press Machines

1. Higher Oil Yield and Lower Oil Loss

(1) Powerful Compression Mechanism: The opposing rotation of the twin screws generates high radial pressure and intense compression.

(2) Thorough Extraction: This intense pressure squeezes out the oil much more thoroughly, leaving minimal residual oil trapped within the remaining mixture of fibers and nuts.

2. Low Palm Nut Breakage

(1) Optimized Pressure Distribution: Despite delivering high extraction pressure, the interlocking design distributes physical force uniformly.

(2) No Kernel Contamination: It achieves efficient oil extraction while maintaining the physical integrity of the hard palm nuts inside the fruit. This prevents crude palm oil (CPO) from getting contaminated by kernel oil, which preserves overall oil purity and quality.

3. High Processing Capacity and Continuous Operation

(1) Large Scale Capability: Unlike single screw palm oil press machines that are generally capped at around 500 kg per hour, double screw palm oil press machines are built for industrial processing capacity, typically ranging from 1 to 15 tons per hour.

(2) Automated Workflow: These double screw palm oil press machines are easily integrated into fully continuous, automated palm oil production lines, drastically minimizing manual labor requirements.

4. Smooth Discharge and Anti-Clogging Features

(1) Positive Conveyance: The double screws work together to forcefully push materials forward.

(2) Self-Cleaning Action: The meshing mechanism prevents thick palm fiber from wrapping around the shafts or clogging the press cage. This ensures a smooth, continuous flow of oil and a mixture of fibers and nuts without material slippage inside the chamber.

Henan Glory Double Screw Palm Oil Press Machine’s Unique Advantages

1. Superior Wear-Resistant Materials

The screws are made of 2Cr13 wear-resistant alloy steel through an integrated casting process. Compared to conventional welded carbon steel screws, these screws offer better wear resistance and hardness, which helps extend service life and maintain consistent performance.

2. Advanced Structural Engineering

The machine’s tail is equipped with a gearbox combined with a hydraulic pump station that drives the two screws to rotate relative to each other. The stirring blades engage to press the palm fruits forward. As the material moves toward the outlet, the gap between the blades decreases, increasing pressure and reducing the residual oil rate to around 6–7%. This design minimizes clogging, reduces manual intervention, and ensures smoother operation during palm fruit pressing.

3. Intelligent High-Pressure System

The integrated hydraulic pump station features easy button controls and can deliver a system operating pressure of up to 100 MPa. The pressure inside the pressing chamber can be monitored and adjusted in real time. The double screw palm oil press machine also uses a hard tooth surface reducer made from durable materials to improve reliability and service life.

4. Simplified Installation and Maintenance

Installation can be completed according to the provided instruction manual and installation video. The double screw palm oil press machine is designed for easy maintenance, and a one-year warranty is provided.
