Crude palm oil is extracted through a carefully monitored series of palm oil mill process that seeks to make sure that the end product is highly appealing. Palm oil extracting plant usually begins with harvesting of the fruit. Below seeks to cover on palm oil extraction process (screw pressing) and field factors that determine quality of expelled palm oil.
Palm Oil Extraction Plant
The following are the main steps that you should keep in mind and follow keenly as you make sure to get a final excellent crude palm oil, which is more suitable commercial palm oil processing plant.
Fresh Palm Fruits Reception Process
For extracting oil from palm fruits, you will have to start by harvesting fresh fruit bunchs and keeping them ready for the next stage of palm oil production. Make sure that they are ripe and in good condition if you are to get a perfect result.
Palm Fruit Threshing Process
After harvesting, you now focus on thresher drum palm oil mill. You start by removing fruits from the bunch and then start threshing. This stage can easily be managed by the use of hand or sometimes the use of mechanic thresher that gives a better finished product. The thresher is well known for its ability to easily vibrate and rotate the fruits as it separates them from the bunch.
Palm Fruit Sterilization Process
Sterilization process in palm oil mill is an important step of palm oil extracting that uses heat to help in the partial cooking of fruits. It is done with a lot of care and following of instructions while at the same time focusing on stopping of enzymatic reactions that are known to cause oxidation and also the disruption of cells in the mesocarp. Through this step, easier extraction of oil is achieved and this makes producers to continue focusing on the next step.
According to experts, wet processes work well with the use of water that sterilizes the fruit through a boiling process or streaming of fruits and production of waste water as the byproduct. On the other hand, the use of dry process helps in the sterilization of the fruits through a roasting process or a perfect smoking process. During the implementation of wet process, the fruit is easily sterilized before any threshing process. In any dry process, threshing of fruits is done after the sterilization process.
Palm Fruit Digestion Process
Palm oil digestion is a process that focuses on crushing of fruits before any extraction of palm oil. It is a better stage that highly focuses on warming the pulp through a perfect process to easily maximize oil yields. This stage calls for maximum concentration and you are also allowed to remove the nut from its pulp before focusing on palm oil milling process stage to yield grade A oil. Another option is to press the mesocarp with the use of nut.
Palm Oil Pressing Process
It is during this stage that you now start focusing on pressing or extracting the oil. Here, the pulp is pressed in palm oil expeller, it burst all cells that contain oil and releases the palm oil. This is an important stage that seeks to focus on several types of presses that usually focus on pressing of fruit pulp.
You can use the Single Screw Oil Press for small or medium scale palm oil production; and Double Screw Oil Press for medium or large scale palm oil extraction. In the modern times, the screw oil press has gained a lot of popularity because of its ability to yield more oil when pressing mesocarp.
Palm Oil Clarification Process
After oil extracting, the oils are usually taken to a clarification section to easily help in the removal of impurities. It is in this stage that the final crude palm oil is received, observed and finally stored in a bulk tank. The oil is kept well to make sure that there are no impurities. It is an important stage that helps in the clarification of the real product and other wastes to make sure that you get the most important product.
Palm Kernel Recovery Process
Nuts and fiber are usually separated in this physical stage after all solids leave the important screw presses. Fiber products here can be used as good biomass fuel in boilers and the nuts used in the extraction process of palm kernel.
