What are the eight steps involved in crude palm oil extraction?

The complete specific eight detailed steps of crude palm oil extraction include raw material reception, sterilization, threshing, digesting, pressing, filtering process and vacuum dryer system and storage. Here are the specific processes of crude palm oil extraction.

The first is raw material reception in crude palm oil extraction. Fresh palm bunches collected from plantations need to be treated within 48 hours to prevent FFA from increasing and affecting the quality of the oil later on. They are transported by truck or other means to the factory, weighed and put into the unloading table for other processes.

Step two is sterilization section in crude palm oil extraction. The purpose of this step is to soften and sterilize the fruit so that it is easy to fall off and press.

Step three is threshing section in crude palm oil extraction. Use a thresher machine to separate the fruit clusters that have been sterilized. The goal is to separate palm fruit from FFB. The empty bunches are collected for fuel or fertilizer, and the fruit moves on to the next stage.

The step four is digesting in crude palm oil extraction. The destruction of the fiber structure facilitates subsequent pressing and helps to improve the final oil yield.

The fifth step is the pressing section in crude palm oil extraction. This is an important step. The oil press is used to press the palm fruit. The fruit and nut are separated from the front part of the oil press and extruded to get crude palm oil and palm nut. The oil press produced by Henan Glory Company has high oil yield and can maintain continuous production.

The sixth and seventh steps are filtering process and vacuum dryer system in crude palm oil extraction. CPO is subjected to a series of filtering processes such as vibrating screen, oil clarification tank and plate filter, layer by layer filtration to ensure the quality of oil. If the water in the oil is not removed, it is difficult to keep it for a long time, so a vacuum drying system is needed. The water in the clean oil under the vacuum condition is stirred to evaporate, and can be directly put into the crude oil tank after drying.

The final step is the storage and crude palm oil transportation in crude palm oil extraction. The crude oil is transported by truck or other means and stored.
