Oil dry fractionation is a physical process used in oil refining industry to separate liquid oils into different fractions based on their melting points, without the use of solvents or chemicals. It’s commonly used in palm oil or palm kernel oil, coconut oil and soybean oil for texture improving.
Dry fractionation is a physical separation method that utilizes the varying melting points of fat components in edible oils, performed without solvents. Through precise temperature adjustments, higher-melting-point fatty acids are separated from the lower-melting liquid fraction. In the case of palm kernel oil, the resulting solid fat fraction is commonly used as a cocoa butter alternative.
Within a crystallization unit, the oil is slowly cooled to promote the formation of semisolid crystals. These high-melting crystals, referred to as stearins, form the solid fraction, while the liquid fraction, known as oleins, is isolated via high-pressure membrane filtration.
The lonnmeter inline analyzers, which require no maintenance, provide real-time monitoring of the dry fractionation process of palm oil by measuring sonic velocity and attenuation. When the desired solid fat content (SFC) is reached, the oil fractions are filtered, delivering consistent, high-quality results.

Integrating a concentration meter for oil into your operations offers multiple advantages, particularly for oil refining, petrochemical, and chemical plants. Here are the core benefits:
These benefits make oil concentration sensors indispensable tools for modern industrial facilities, particularly those focused on the dry fractionation of palm oil or similar processes.
Selecting the appropriate oil concentration meter depends on your plant’s specific needs. Factors to consider include measurement range, environmental conditions, and integration with existing systems. Coriolis concentration meter and ultrasonic concentration meter are two appropriate options for viscous liquid.
An oil concentration sensor is a device that measures the concentration of oil in real time, typically using technologies like ultrasonic or vibrational methods. It provides continuous data on oil concentration, enabling precise control of industrial processes like the dry fractionation of palm oil. By detecting changes in concentration, the sensor helps operators maintain consistent product quality and optimize production parameters.
A concentration meter for oil reduces costs by minimizing waste, optimizing resource use, and preventing costly rework due to quality issues. In processes like oil dry fractionation, real-time monitoring ensures that the oil meets specifications without requiring excessive energy or raw materials, directly impacting the bottom line.
In today’s competitive industrial landscape, adopting advanced technologies like an oil concentration sensor is essential for oil refining, petrochemical, and chemical plants. These devices provide real-time insights, enabling precise control of processes like the dry fractionation process of palm oil. By enhancing efficiency, reducing costs, and ensuring compliance, an oil concentration meter delivers measurable value to your operations.
