Firstly, the fruits go through a process known as threshing, in which each piece of fruit is separated from the rest of the bunch.
After threshing, the next step in palm oil production involves pressing the fruit to separate the oil from the skin and pulp. Some facilities place the fruit into large rotating drums, which start to break down the fruit and release some of the oil. This is followed by pressing, wherein heavy metal plates are mechanically pressed into the fruit to squeeze out the oil. Pressing machines may use hydraulic or pneumatic power to process large batches at once. The oil is then diluted with water and filtered through a screen to help remove debris and impurities. Crude palm oil need to put into palm oil refinery machine for further processing.
Palm oil extraction process is a complex process. If you have problems about palm edible oil refining plant, pls feel free to contact us.
Three Kinds of Edible oil refining plant Methods Introduction
The three most popular methods of Edible oil refining plant from vegetables, nuts and seeds are
1. Edible oil refining plant Chemical solvents
2. Edible oil refining plant Screw oil press (expeller
3. Edible oil refining plant Centrifuge
Often, more than one method is used, this in order to squeeze the most oil out. The process usually begins with cracking the hull of the nut and then applying one of the aforementioned methods, followed by another.
The solvent Edible oil refining plant method is very popular, and uses hexane, which is a poisonous chemical. The process is very effective and usually recovers 99% of the oil. However, in order to get rid of the hexane, the oil is heated to a high temperature. This changes the flavor profile and for some delicate oils like olive oil, may ruin the flavor altogether.
Mechanical pressing may create high temperatures, especially when squeezing hard nuts. This usually happens when working with automatic machinery in high volume. The issue with high temperatures, as we mentioned before, is that they change the flavor of the oil.
Mechanical Edible oil refining plant is how things were done for centuries. Applying heavy pressure to olives or seeds until oil starts seeping out. An expeller is a big screw that is tightened until it crushes the nut/seed and causes the oil to run. This method provides yields of only 65-70% of the oil. Many companies then try to extract the rest of the oil using the chemical solvent.
The above are three Edible oil refining plant methods, if you have any questions about that, please consult ou staffs, they will give you professional suggests.
