Palm Oil Production Line

Palm oil production line includes three sections, palm oil pressing plant, palm oil refinery plant and palm oil fractionation plant. As the manufacturer of the palm oil production line, we can offer the whole line or part of the palm oil production line for different capacities with turnkey services.

1.Palm Fruit Receiving Section
It is mainly used for collecting the palm fruits. Palm fruits are weighed first after transporting to the plant, then they will be loaded on a slope. Under the slope, there are some cages to receive the palm fruits.

2. Sterilizing
Generally, the palm fruit we collect must be sterilized in 48 hours to prevent the acid value from raising by lowering the activity of fatty enzymes. The sterilizing time is 90-120mins, and the temperature is 130-145℃. After sterilizing, threshing becomes easier, and the broken rate of palm kernel is reduced.

3. Threshing
The palm fruit is softened in sterilizing process, then sent to the threshing machine. Palm fruit threshing machine uses strong vibration to separate the palm fruit from palm bunches. Palm fruit after separation is delivered to the pressing plant. And the empty bunches can be used as fertilizer in farmland or palm fruit plantation or pressed into fuel pellets.

4. Crushing
The palm fruit is crushed by crusher through stirring and squeezing. The purpose of crushing is to destroy the palm skin, separate the palm pulp and nuts, pound the palm pulp and damage the cell structure of palm pulp, which is good for the later pressing process.

5. Pressing
The crushed palm fruit is delivered to the oil press, palm oil screw press is the common equipment we use, wherein heavy metal plates are mechanically pressed into the fruit to squeeze out the oil. Palm fruit pulp cell can be destroyed under the high-temperature condition, after that we can get higher oil yield. Finally, we get the oil-water mixture and cake. Mixture of oil-water and impurities will be delivered to the clarification section, and the cake will be crushed for fiber recycling.

6. Clarifying
The crude palm oil contains some water, sludge, and other impurities. After the preliminarily clean of the subsiding tank and vibrating screen, the crude palm oil flows into the vertical clarifying tank. The oil mixture is heated to 85-90℃ and allowed to separate in the clarification tank. A settling time of 1-3 hours is acceptable. Oil from the top is skimmed off and purified in the centrifuge prior to drying in the vacuum dryer. The final crude palm oil is then cooled and stored. The lower layer from the clarification tank is sent to the centrifugal separator where the remaining oil is recovered. The oil is dried in the vacuum dryer, cooled and sent to the storage tank.

7. Filtering
Plate and frame filter can filter out most of the impurities to make the crude palm oil reach the standard of edible oil. At this stage, the palm oil can be sold as a low-quality palm oil or sent on for further processing. For further processing of palm oil, the palm oil refining process and palm oil fractionation process is necessary.

Palm Oil Introduction
Palm oil is derived from the fruit of oil palm tree, which is grown in tropical regions of Asia and Africa. Saturated fatty acid and unsaturated fatty acid account for about 50% respectively, which endow the palm oil with better oxidative stability than other vegetable oils. Therefore, it is more suitable for frying and cooking. Currently, the palm oil is a kind of vegetable oil with the largest production, consumption and international trade volume in the world. After refining and fractionating, we can get the palm oils with different melting points, which have wide applications in the catering industry, food industry and oil and chemical industry.
