What Is the Palm Fruit Pressing Process and How to Improve Oil Yield?

Are you troubled by low palm oil yields and inconsistent oil quality? Missing the optimal harvest period not only wastes raw materials but can also negatively impact the economic performance of the entire production line. This article will explain the complete palm fruit pressing process and share professional equipment and customized solutions to help oil mills rapidly increase oil yields and achieve efficient production.

1. Sterilization pretreatment: ensure the freshness of raw materials

Palm fruit is rich in unsaturated fatty acids and is prone to rancidity. Therefore, after being weighed, the fresh fruit clusters first enter a vertical sterilization tank where they are rapidly heated to kill fermentation and enzymes, preventing oil degradation and preserving the freshness of the raw material to the greatest extent possible. Next, the clusters enter a thresher, where the fruit bunches are automatically separated from the kernels. The empty bunches are then discharged via a conveyor, achieving efficient pre-treatment.

Advantages:

• Vertical sterilization tank design takes up little space and saves labor;

• Efficiently inactivate enzymes, prevent oil rancidity, and increase oil yield;

• Optimize the pretreatment process, reduce raw material loss, and improve subsequent pressing efficiency.

2. Pulp pressing and oil extraction: efficiently releasing golden nutrients

After being steamed and crushed, the palm fruit enters a specialized press. Under intense mechanical pressure, the oils in the pulp are fully released, forming crude palm oil. Simultaneously, the wet fiber cake is separated and reused as boiler fuel, reducing overall production costs.

Advantages:

• High pressing efficiency and low oil loss;

• Utilize by-products as resources to achieve sustainable development.

3. Crude oil clarification: obtain clear crude oil

Crude oil contains impurities and moisture, and needs to pass through multi-stage vibrating screens and clarification tanks to gradually remove solid impurities by layers, and then use a vacuum drying process to remove moisture and residual impurities to obtain palm crude oil with clear color and stable quality.

Advantages:

• Double separation process to ensure oil purity;

• Vacuum drying technology improves oil storage stability;

• Improve the quality of crude oil and lay a good foundation for refining.

4. Nucleus Resource Utilization: Zero Waste Recycling

The wet fiber cake is separated into palm kernels by air separation equipment. The kernels then enter shelling, crushing, shell-kernel separation, and kernel drying. After careful processing, the resulting palm kernels can be used to extract palm kernel oil and as feed or other industrial raw materials, achieving a recycling of by-products.

Advantages:

• Full closed-loop recycling to reduce waste;

• Diversified utilization to improve economic benefits.

FAQ

1. What is the approximate price of a palm oil press?
The price depends on the equipment's production capacity and degree of automation. Small palm oil press machine typically cost tens of thousands of RMB, while large, fully automated production lines can cost hundreds of thousands to millions of RMB. QIE Group will provide a reasonable solution based on the client's budget and production requirements.

2. How much investment is required to build a palm oil production line?
The scale of investment depends on daily production volume, plant size, and process configuration. Generally speaking, a small or medium-sized production line processing 10-20 tons per day will require an investment of several hundred thousand yuan, while a large-scale plant may require tens of millions of yuan.

3. What is the oil yield of a palm oil press?
Oil yield is related to the freshness of the raw materials, the sterilization process, and the performance of the equipment. Using our high-efficiency oil press, the oil yield of palm fruit can be maintained at around 20%–23%, with stable oil quality.

4. Can the palm oil production line be customized?
Yes. We provide customized design and installation services, from single machines to complete palm oil production lines, based on your raw material requirements, production capacity requirements, and market positioning.

5. Besides crude palm oil, what other by-products can be obtained?
Through scientific separation and processing, palm kernels (for extracting kernel oil), shells (for fuel), and fibers (for use in boilers) can be obtained, realizing resource utilization of by-products and improving overall benefits.

The palm fruit pressing process not only affects the quality of the oil product but also determines the economic benefits of the oil mill. By scientifically configuring the palm fruit pressing process and a complete palm oil production line , the oil mill can achieve efficient production, stable quality, and sustainable development.
