Crude Palm Oil Milling Process

Palm oil mill is designed to produce crude palm oil and kernels, as primary products and biomass as secondary product. This comprises of sterilization, stripping, digestion and pressing, clarification, purification, drying and storage. For the crude palm oil milling process, there are steps such as nut/fibre separation, nut conditioning and cracking, cracked mixture separation, and kernel drying, storage. The dried kernels are often sold to palm kernel crushers for the crude palm oil milling process of crude palm kernel oil. In some integrated plants, kernel crushing facilities exist side by side at the same complex.

Crude Palm Oil Milling Process

There are two distinct crude palm oil milling process methods of extracting oil from the digested material. One system uses mechanical presses and is called the ‘dry’ method. The other called the ‘wet’ method uses hot water to leach out the oil.

In the ‘dry’ method the objective of the crude palm oil milling process stage is to squeeze the oil out of a mixture of oil, moisture, fibre and nuts by applying mechanical pressure on the digested mash. There are a large number of different types of presses but the principle of operation is similar for each. The presses may be designed for batch (small amounts of material operated upon for a time period) or continuous operations.

Conversion of crude palm oil to refined oil involves removal of the products of hydrolysis and oxidation, colour and flavour. After refining, the crude palm oil may be separated (fractionated) into liquid and solid phases by thermo-mechanical means (controlled cooling, crystallization, and filtering), and the liquid fraction is used extensively as a liquid cooking oil in tropical climates, competing successfully with the more expensive groundnut, corn, and sunflower oils.

Crude palm oil milling process of all sizes go through these unit operational stages. They differ in the level of mechanisation of each unit operation and the interconnecting materials transfer mechanisms that make the system batch or continuous. The scale of operations differs at the level of process and product quality control that may be achieved by the method of mechanisation adopted. The technical terms referred to in the diagram above will be described later.

Crude Palm Oil Milling Process

Crude palm oil is very rich with its own vitamin and mineral which is characterized as stabilized oil due to its chemical composition. As such, it can be used in most food applications without hydrogenation, thus, reducing production cost by as much as 30%.  Compared to other edible oils,crude palm oil also is priced competitively and can represent a saving of upto several cents per pound.

We have rich experience in designing and manufacturing of crude palm oil milling products to the highest specifications. We also offer very professionl crude palm oil milling process.Contact us for more information in the following form.
