Technology of Palm Oil Production Line

This solution covers all aspects of a palm oil mill, from the initial design and planning stages to commissioning and ongoing operation.

YAHUA uses advanced technology, high-quality equipment, and a professional service team to ensure that the entire process runs efficiently and stably.

The palm oil press production line we have developed and designed features high oil yield and low production costs, meeting environmental protection and oil quality standards.

We can customize design solutions for large, medium, and small-scale construction projects based on customers' requirements for different production capacities.

Palm oil is one of the most important vegetable oils globally, widely used in food, cosmetics, and chemical industries. With the continuous growth in demand for palm oil, establishing an efficient and sustainable palm oil pressing plant is crucial for producers. Our palm oil pressing plant solutions are designed to meet these needs, providing customers with one-stop services from plant planning, equipment procurement, installation, commissioning, to after-sales support.

Process of Palm Oil Production Line

• Fresh fruit bunch sterilization: Fresh palm fruit bunches are loaded into sterilization tanks via a scraper conveyor and steamed at high temperatures (145°C steam) for 80– 90 minutes, thereby reducing enzyme activity and inhibiting the increase in free fatty acids (FFA). This ensures the quality of crude palm oil and provides conditions for subsequent processes.

  
  

• Pressing: After sterilization and threshing, the fruit kernels enter the crushing tank, where they are stirred and crushed into a paste. They then enter a twin-screw press for squeezing, where oil and water are extracted, and the press cake, consisting of palm kernels and fruit flesh fibers, is separated and broken up by a screw conveyor to the next stage.

  
  

• Oil clarification: The oil clarification station reduces the moisture and impurities in the crude oil after pressing to meet market sale standards. The crude oil after pressing undergoes filtration, sedimentation, sand removal, centrifugal separation, and vacuum drying processes to remove moisture and impurities from the palm crude oil.

  
  

• Steam power supply: The boiler serves as the steam and power source for the factory. A biomass boiler fueled by palm empty fruit bunches generates high-pressure, high-temperature steam, which is used to drive a back-pressure steam turbine generator to provide electricity. The exhaust steam is utilized in production processes as a heat source, achieving biomass reuse, self-sufficient electricity, and self-sufficient steam, thereby reducing production costs and enhancing environmental benefits.

  
  

• Wastewater treatment system: The wastewater generated by the palm oil factory contains many harmful substances and recoverable oil. The discharged wastewater undergoes condensation and sedimentation, with the upper oil layer recovered and the lower wastewater treated to reduce BOD, COD, and other pollutants. The treated wastewater is then recycled for use in production processes, achieving water reuse and reducing environmental impact.

Equipment of Palm Oil Production Line

• Sterilizer Tank: Commonly used types include vertical and horizontal sterilizer tanks. Fresh fruit bunches are steamed at high temperatures (145°C steam) for 80–90 minutes, thereby reducing enzyme activity and inhibiting the increase in free fatty acids (FFA). This ensures the quality of crude palm oil and provides conditions for subsequent processes.

  
  

• Thresher drum: The steamed and sterilized ripe fruit bunches (SFB) are passed through a drum-type rotating drum to separate the palm fruits from the empty fruit bunches.

  
  

• Double-screw press: The Yahua Palm Oil Production Line uses a double-screw press,    where two screws work in tandem to more effectively squeeze the oil material, enhancing pressing force and efficiency. This ensures the oil material is thoroughly squeezed and kneaded within the pressing chamber, thereby increasing oil yield.

  
  

• Purification Equipment: Filters, centrifuges, and other equipment remove impurities from crude palm oil to improve its quality. A three-stage centrifugal filtration system can reduce impurity content to ≤0.1%.

Science of Palm Oil Production Line

• Automatic control system: Used to monitor and regulate various process parameters such as temperature, pressure, and flow rate, ensuring precise operation and minimizing human error.

  
  

• Steam heating technology: Applied in sterilization and cooking processes to ensure uniform heating of palm fruits and efficient energy utilization. This improves oil yield and oil quality.

  
  

• Dual-screw pressing technology: Utilizes variable-diameter, variable-pitch screw shafts made of wear-resistant alloy steel. This technology applies higher pressure,   effectively extracting oil while minimizing nut breakage, thereby reducing residual oil content and improving oil quality.

  
  

• Intelligent Temperature Control Technology: Real-time monitoring and precise control of the temperature within the pressing chamber (90–130°C) prevent oil oxidation and degradation, ensuring the quality of crude palm oil.

  
  

• Centrifugal Filtration Technology: Utilizing centrifugal force to separate impurities from the oil, achieving efficient purification to ensure crude palm oil meets refining requirements.
