Palm kernel oil extraction
Palm kernel oil is an edible plant oil derived from the kernel of the oil palm Elaeis guineensis.It should not be confused with the other two edible oils derived from palm fruits: palm oil, extracted from the pulp of the oil palm fruit.
Mechanical extraction processes are suitable for both small and large capacity operations, the three basic steps in these processes are kernel pre-treatment, screw-pressing and oil clarification. Proper kernel pre-treatment is necessary to efficiently extract the oil from the kernels. The feed kernels must first be cleaned of foreign materials that may cause damage to the screw oil press, Magnetic separators commonly are installed to remove metal debirs, while vibrating screens are used to sieve sand, stones or other undesirable materials.
Some mills crush the kernels diretly in the presses without any pre-treatment, double pressing usually is required to ensure efficient oil extraction. The kernel are first broken down to smaller fragments by grinding prior to screw pressing. In some cases, cooking is also carried out.
Solvent extraction processes can be divided into three main unit operations: kernel pre-treatment, oil extraction, and solvent recovery from the oil and meal. For the purposes of small scale operations, it is sufficient. The solvent extraction process is an alternative for high capacity mills. However the proess is not recommended for small enterprises.
