Palm kernel oil is an edible plant oil derived from the kernel of the oil palm while palm oil or palm fruit oil is extracted from palm fruits. The way to distinguish palm kernel oil and palm oil is very easy. Palm kernel oil is white while palm oil is red and brown. And palm kernel oil is in solid, not liquid. Palm kernel oil is commonly used in commercial cooking because it is lower in cost than other vegetable oils. Palm kernel oil can be stored longer than other oils.
Full pressing, solvent extraction and pre-pressing solvent extraction is the three main oil extraction methods of palm kernel.
Full pressing extraction is also called single pressing, which is a physical extraction method that squeezing oil out under high pressure by use of mechanical screw oil press. The typical process of screw oil pressing plant is: palm kernel crushing, flaking, steam conditioning, mechanical oil expelling and oil filtering. Production cost depends mainly on mechanical wear and tear, electricity and maintenance expenses. Below is some of our Palm Kernel Oil Pressing projects.
Full pressing method is suitable for both small and large palm kernel oil mill plant, while solvent extraction method is generally applied to large scale oil mill plant. If you are planning to start palm kernel oil extract business, ensure your capital investment and your daily capacity before deciding the oil production process.
Solvent extraction plant separate the oil by mixing solvent in the material. Production cost depends mainly on solvent loss and energy used in solvent recovery. Compared with screw pressing, the oil recovery of solvent extraction plant is more complete.
Pre-pressing & solvent extraction is another popular palm kernel oil production method.After oil pressing or extracting, the oil then requires clarification in a filter press or by sedimentation. To ensure premium quality of final oil and by-products, palm oil mill should have strict quality control from fresh palm bunch processing to kernel oil extraction. Build palm kernel oil extraction plant with professional oil production process is the very first step to the success of your business.
