palm oil processing steps, how to process palm kernel oil

Oil palm extraction steps are: sterilization, the bunches are cooked with live steam for 120 minutes, sterilization aimed at enzyme inactivation, making fruits separate from bunches, making fruits softer, making nut pulp separation easier and coagulation of proteins.

Threshing, after bunches are cooked they are fed to the thresher which is a drum with holes in the side where bunches are centrifuged to separate the fruits, the bunches waste is incinerated and the ash, a rich source of potassium, is used in a compost.

Digestion, digestion is the process of releasing the palm oil in the fruit through the breaking down of oil bearing cells, the main aim during digestion is to break oil cells, in order to make oil extraction easier, the process takes 30 minutes at 90 ℃。

Pressing, pressing is made just after the material leaves the digestion vessels and it produces a slurry made of approximately 53% oil, method of pressing could be dry or wet, dry method is oriented on squeezing the oil out of the mixture of oil, moisture, fibre and nuts by applying mechanical pressure on the digested mash, wet method used hot water leach out the oil.

Clarification, purification and packaging, the step includes separation of oil from impurities such as water and fine solids made in setting tanks and three phase decanters, recovered oil is then purified in plate centrifuges and dried under vacuum, finally the extra virgin palm oil is filter to remove any remaining particulate matter and packaged in drums.
