As we all know, oil palm is a kind of important tropic oil seed plant. The oil extraction rate of oil palm is very high:palm fruit: 46%-50%, palm kernel: 50%-55%.
Usually there are many palm oil mills in Malaysia, Indonesia, Nigeria, Liberia. After palm fruit oil pressing, we can get crude palm oil and palm kernel.But the palm kernel with fiber are remained. Many people sell palm kernel to others. In fact, palm kernel oil is more valuable than palm fruit oil. We can also process palm kernel and get palm kernel oil.The below is the process of extracting palm kernel oil from palm kernel.
Palm kernel oil extraction process
Palm kernel oil extraction process:
◆ Palm kernel Cleaning : It is used for removing the iron impurities, stone, fiber and others. These impurities are bad for palm kernel oil machines, especial for the palm kernel oil expeller.
◆ Palm kernel crushing:because the palm kernel is hard and big size, it is required to crash to smaller and even pieces.
◆ Palm kernel and nuts shell separation. Both dry and wet separations are available. Wet separation is mostly used in palm kernel separation, on basis of difference of relative density of palm kernel and shell.
◆ Palm kernel drying. Fresh kernel contains 20% moisture. Palm kernel has no mildew during transportation and storage while moisture drops below 7%.
◆ Cooking section: It is used for heating and cooking the crashing materials, to make is suitable for pressing, doing like this can help final user get the maximum oil and good quality cakes.
◆ Palm kernel oil pressing. Palm kernel oil pressing processing line is simple with usual oilseeds. The pre-pressing by oil pressing machine can obtain 1/4 palm kernel oil, and residual oil need twice pressing.
◆ Palm kernel oil Filtering section: after pressing, there are some oil dregs in the crude oil, after clarifying, we need to filter the crude oil to avoid to jam the oil pipes during refining processes.
We have been specialized in palm kernel oil expeller machine for decades.
