How many ways to extract palm kernel oil?

There are two common methods of extracting palm kernel oil, one is full press extraction where mechanical screw oil press machines are used to extract oil out by squeezing under high pressure, this oil extracting method is mainly used by small and big capacity oil mill plants. The other method is palm oil solvent extraction with hexane, where a solvent is mixed with the material to separate the oil, this extracting method, however, is generally used by larger capacity oil processing mills. You can choose the one that suits you best according to your daily capacity.
Full Press Extraction / Mechanical Extraction

1.palm kernel pre-treatment:

Kernels must be well pre-treated before putting into oil press mills. In the process, you will need several types of seed cleaning equipmen such as grinder, vibrating separator, destoner, magnetic separators, cooker, etc.

There are two reasons why proper kernel pretreatment is important, for one hand, pre-treatment process can get rid of foreign materials that may cause damage to our machinery and thus increase machine’s service life and reduce the maintenance cost as well. On the other hand, palm kernel pretreatment can also enhance the production productivity.
2. extracting by palm oil presses:

Put the well prepared palm kernel meal to the feeder of the screw oil press and start extracting oil! The meal is forced through the barrel by the action of the revolving worms. The volume axially displaced by the worm diminishes from the feeding end to the discharge end, thus compressing the meal as it passes through the barrel. The expelled oil drains through the perforation of the lining bars of the barrel, while the de-oiled cake is discharged through an annular orifice.three way of palm kernel oil extraction

3.oil clarification

oil filter press
The extracted crude palm kernel oil inevitably contains ‘fines and foots’and other impurities that need to be removed. In order to  get vegetable oil for edible, the crude palm kernel oil need to be pumped to a filter press to get rid of the remaining impurities in the oil. The cakes discharged from the presses are conveyed for bagging or bulk storage.

Solvent extraction method is recommended for much bigger capacity oil mils, for small capacity oil extraction mills, the former method will be better. Solvent extraction processes can be divided into three main unit operations: kernel pre-treatment, oil extraction, and solvent recovery from the oil and meal.
