How to extract oil from palm fruit

Palm oil screw press is a device specifically designed to extract oil from palm fruit. The following is a detailed introduction to it:

The working principle of the palm oil screw press is mainly based on pressure and friction. Palm fruit enters the oil press through the feeding hopper and is then subjected to continuous pressure and friction under the propulsion of the screw shaft. The design of the spiral shaft has specific threads that can provide gradually increasing pressure to squeeze out the oil in the palm fruit. This process can be likened to the process of water flowing out of a pipe, except that the palm fruit is squeezed and the palm oil flows out.

The main components of a palm oil screw press include:
Feeding hopper: used to receive palm fruits and feed them into the oil press.
Spiral shaft: with a specific thread design, responsible for pushing palm fruit and applying pressure.
Squeezing cage: used to hold palm fruits and extract oil under the pressure of a spiral shaft.
Discharge outlet: responsible for discharging squeezed palm fruit residue.
Power system: Provides the power required for the operation of the oil press, usually an electric motor or diesel engine.

Palm oil screw presses can be classified into various types based on their processing capacity and structural characteristics, such as single screw and double screw presses.
Single helix palm oil press:
Features: Easy to operate, easy to maintain, and highly automated. Suitable for small-scale palm oil extraction plants with processing capacities ranging from 300 to 500 kilograms per hour. Small footprint, low investment cost, equipped with diesel engine or generator to ensure the normal operation of the oil press. The equipment has excellent material, good wear resistance, and long service life.
Double helix palm oil press:
Features: High oil yield, easy operation, high degree of automation. Suitable for palm oil extraction plants of large, medium, and small sizes with processing capacities of 15 tons/hour and 5120 tons/hour. There are multiple processing capacities to choose from, equipped with two power systems: diesel engine and electric motor, allowing for the selection of suitable engines based on local infrastructure conditions. The design of its hydraulic bolt spiral rod enhances the compression effect of palm fruit, improves the accuracy of operation and oil output. The use of high-strength martensitic stainless steel instead of conventional carbon steel material has improved the wear resistance and service life of the equipment.
