Optimize your palm oil extraction line: fractionation process & equipment explained

The natural characteristics of palm oil determine that it will form components with different melting points at different temperatures. The palm oil fractionation process uses this characteristic to separate palm oil into liquid palm oil and solid palm stearin by controlling the cooling and filtration process, thereby greatly expanding the application range of palm oil. By optimizing this link in the palm oil extraction line, customers can use it to improve product applicability, improve food quality and health, and expand applications in non-food industries. The following will introduce why it is necessary to optimize the palm oil extraction line as well as the palm oil fractionation process and equipment.

What is Palm Oil Fractionation Process?

Palm oil fractionation process achieves product diversification through physical separation. The core of the process lies in crystallization control, and parameters need to be adjusted in combination with extraction goals. Palm oil fractionation process optimize palm oil extraction line. Its advantages are mainly reflected in the following aspects: improving product diversity, improving oil performance, and increasing economic benefits, etc. This step is essential for producing high-quality cooking oil, margarine, shortening, and specialty fats. The palm oil fractionation process achieves efficient utilization of resources through physical separation, taking into account functionality, healthiness and economy, and is one of the key technologies in oil processing.

Palm Oil Fractionation Process & Equipment Explained

1. Palm Oil Fractionation Pretreatment Equipment

The heating tank heats the crude oil to 60~70℃ .

2. Palm Oil Fractionation Core Equipment

· Crystallization system

The crystallization tank is a closed container with stirring and cooling devices. The oil is pumped into the crystallization tank and slowly cooled to the initial crystallization temperature (usually 45-50°C) through a heat exchanger. Slow stirring (10-20 rpm) ensures uniform growth of crystals and avoids local overheating. During the crystallization process of palm oil fractionation, high melting point triglycerides (such as stearin) are formed into crystals by slow cooling.

· Water cooling circulation system

It is used to accurately control the cooling rate to ensure stable growth of crystals.

· Solid-liquid separation system

The plate and frame filter is a commonly used traditional method, suitable for small-scale extraction, with a filter cloth pore size of 5~10μm. The operating pressure is -0.08~-0.1 MPa, and the separation efficiency is >90%. Olein is the low melting point part, in liquid form, flowing out through the filter. Stearin is the high melting point part, and solid crystals remain on the filter cloth.

· Temperature control system

The refrigeration unit provides cooling medium (such as cold water, refrigerant) to control the crystallization temperature (usually 0~25℃). Plate or tube heat exchanger is used for oil temperature regulation.

The above is an overview of the palm oil fractionation process and palm oil fractionation equipment. The palm oil fractionation process optimizes palm oil extraction line and it is a complex technology that can fully realize the potential of this versatile vegetable oil. By selectively separating its components into specialized fractions, it can meet the various needs of the food industry while improving product quality and functionality. With the continuous development of palm oil fractionation process, the application prospects of palm oil in food and non-food fields will be further expanded.
