Palm kernel oil is an edible plant oil derived from the kernel of the oil palm Elaeis guineensis.It should not be confused with the other two edible oils derived from palm fruits: palm oil, extracted from the pulp of the oil palm fruit.

Mechanical extraction processes are suitable for both small and large capacity operations, the three basic steps in these processes are kernel pre-treatment, screw-pressing and oil clarification. Proper kernel pre-treatment is necessary to efficiently extract the oil from the kernels. The feed kernels must first be cleaned of foreign materials that may cause damage to the screw oil press, Magnetic separators commonly are installed to remove metal debirs, while vibrating screens are used to sieve sand, stones or other undesirable materials.

Process Flow of Palm Kernel Oil Extraction Line

Some mills crush the kernels directly in the presses without any pre-treatment, double pressing usually is required to ensure efficient oil extraction. The kernel are first broken down to smaller fragments by grinding prior to screw pressing. In some cases, cooking is also carried out.

Solvent extraction processes can be divided into three main unit operations: kernel pre-treatment, oil extraction, and solvent recovery from the oil and meal. For the purposes of small scale operations, it is sufficient. The solvent extraction process is an alternative for high capacity mills. However the process is not recommended for small enterprises. We established a cooperative relationship with clients all over the world and enjoys popular acclaim because of our professional products and personalized service. Look forward to co-operating with you.

Working process of palm kernel oil extraction line

(1) Palm kernel cleaning:

Palm kernel cleaning equipment is mainly used to remove iron wire, stone, fiber and other impurities in palm kernel. These impurities are easy to damage the machine, especially the palm kernel oil press;

(2) Palm kernel crushing equipment:

Palm kernels generally need to be crushed twice, one crushing: because the palm kernel is relatively large and hard, in order to better improve the oil yield, it needs to be crushed first. Secondary crushing: mainly to break the palm kernel into small pieces for easy oil extraction.

(3) Palm kernel shell separation equipment:

Both wet separation and dry separation are available. Which separation method to use mainly depends on the processing capacity of palm kernels, the cleanliness of separation, and the customer’s financial situation;

(4) Palm kernel drying equipment:

Fresh palm kernels contain 20% moisture, and the moisture content of palm kernels must be reduced to less than 7% in order to store them;

(5) Palm kernel steaming and frying equipment:

Mainly through heating and steaming and frying, the palm kernel can achieve good oil production conditions, so that more high-quality palm kernel oil can be obtained;

(6) Palm kernel oil press equipment:

The palm kernel oil press is the same as the conventional oil press and can be used in general. Through pressing, we can get crude palm kernel oil.

(7) Palm kernel oil filtration equipment:

Crude palm kernel oil contains a lot of impurities, and palm kernel oil filtration equipment can enable us to obtain higher quality palm kernel oil.

What is the yield of crude palm oil?

After experimental studies, the oil yield of tons of crude palm oil is about 20%-23%. Of course, the oil yield is not fixed, it is affected by many factors, such as the ripeness of the palm fruit, the size and quality of the fruit, the method and time of harvesting, etc. Therefore, in actual operation, it must be adjusted according to the actual situation. The oil content of palm oil extracted from the fruit varies from 17% to 27%, while the kernel varies from 4% to 10%.

Palm yield

136 palm trees/Ha=20-23t FFB/Ha/year

CPO=4-5t/Ha/year

CPKO = 0.55 t/Ha/year

FFB=10-25Kg

FFB= 20% CPO; 2.5% CPKO

Cost analysis of processing 10 tons /H palm fruit

If your palm fruit processing capacity is about 1-5 tons/hour, you can choose the standard configuration of palm oil production line equipment, mainly by the fermentation tank, fruit extractor, mashing tank, palm oil press, rotary sieve and plate and frame filter and other equipment, the investment is generally from hundreds of thousands to millions, mostly suitable for medium-sized palm oil processing plants.

Feasibility analysis of investment in palm oil processing plant:

Investment in palm oil processing plants has a stable and broad market development prospects, mainly reflected in the palm oil processing raw materials sufficient, large market demand, and large profit margins.

1, Palm fruit raw materials are sufficient

The palm fruit tree is a long-term crop with four flowering and fruiting seasons. It can provide a stable and continuous supply of raw materials for palm fruit processing, and the yield per hectare of palm fruit is 5 times higher than that of peanuts in the same area, and 9 times higher than that of soybeans. People who have seen oil palm trees know that the fruit of oil palm trees is very rich, a large string, the fruit is orange red when ripe, and the average weight of each string can reach more than 100 pounds. In addition, the growth cycle of oil palm trees is perennial, blooming and bearing fruit all year round, and can harvest several times a year. And not only the fruit, the peel can also be used to press oil, so the oil yield per unit area of palm oil is also quite high. It requires very little to grow an oil palm tree, a tropical fruit tree that can survive in Asia, the Americas, and Africa. As long as the external environment meets its growth, it will seize resources and strive to grow at all costs.

2, Palm oil market demand is large

At present, the palm oil imported from China is mainly used in the processing of composite edible oil, because of its low boiling point, many are used in the processing of instant noodles and biscuits. Palm oil also has many uses in the catering, food industry and oil and grease chemical industry. Palm oil is currently the world’s largest vegetable oil production, consumption and international trade volume, accounting for 30% of the world’s total oil consumption. This means that the market demand for palm oil is very high.

3, Palm oil has large profit margins

The net profit and rate of return on the production investment of palm oil processing plants are often the focus of our attention and one of the main criteria to measure the development prospects of palm oil projects. The net profit margin of palm oil is about 5% higher than that of soybean oil and peanut oil.
