Technology of Palm Kernel Oil Extrusion Process

Palm kernel oil is rich in lauric acid C12 and myristic acid C14. It is a key raw material for high-end personal care products and surfactants. Market demand for palm kernel oil has been increasing year by year, with supply failing to meet demand. It is widely used in health foods, pharmaceuticals, cosmetics, detergents, and other products, possessing significant market value.

Process

• The main process flow for palm kernel oil pressing includes: palm kernel drying -> first pressing -> second pressing -> oil clarification -> oil filtration -> oil drying.
  
  
• The final products of this production line are crude palm kernel oil (CPKO) and palm kernel meal (PKM). Palm kernel meal is processed through crushing, fermentation, and packaging for use as animal feed ingredients.
  
  
• The palm kernel oil production line designed by Yahu features high automation, stable operation, strong processing capacity, high oil yield, and low energy consumption, enabling continuous and large-scale production of palm kernel oil.

Technology

• Second pressing technology: Using second pressing technology, the raw material is subjected to deep compression to further improve oil extraction efficiency.
  
  
• Vacuum Drying Technology: This technology allows moisture in the oil to evaporate at lower temperatures, effectively preventing high temperatures from damaging oil quality. After vacuum drying, palm kernel oil has a moisture content as low as 0.2% or below, meeting the requirements for oil storage and subsequent processing.
  
  
• Automated Control Technology: The production line is equipped with advanced distributed control systems (DCS) and programmable logic controllers (PLC) to achieve comprehensive automated control and real-time monitoring of the entire production process, ensuring efficient, stable, and continuous operation.

Equipment

• Screw Oil Press: Based on the characteristics of the raw material, Yahu engineers optimized the design of the screw oil press, such as adopting a special screw shaft structure and pressing chamber shape to adapt to the texture and oil content of the pressed cake, thereby enhancing the equipment's service life and oil yield.

  
  

• Blade Filter: The blade filter effectively removes solid particles and gums from palm kernel crude oil, thereby improving the quality of palm kernel oil and protecting the normal operation of subsequent equipment.
  
  
• Vacuum Dryer: Comprising a vacuum tank, vacuum system, heating system, stirring system, condensation system, and control system, the vacuum dryer effectively removes moisture from oils at lower temperatures, preventing thermal oxidation and nutrient loss, thereby improving oil quality and stability.
