edible oil chemical refining line

Complete Chemical Refining Line for Oil Processing

Chemical refining is a commonly used method in edible oil processing. It removes free fatty acids (FFA) from crude oil by using an alkaline solution (usually caustic soda), helping improve oil quality and stability.

This method works well for many types of oils, especially those with relatively low or variable quality, such as soybean oil, sunflower oil, and rapeseed oil.

Process & System Features:

  • Neutralization using caustic soda to remove FFA effectively
  • Separation via batch settling (small-scale) or centrifugal systems (large-scale)
  • Followed by bleaching and deodorization for improved color, taste, and stability
  • Flexible configuration based on production capacity and oil quality

The system can be designed for both small and large production needs. With its flexibility and stable performance, chemical refining remains a practical and reliable choice for many oil producers.

Until now, we have helped our customers to establish edible oil refinery projects with different capacities in at least 30 countries, including Australia, India, Bangladesh, the Philippines, Korea, Jamaica, Zambia, Chile, Afghanistan, Nigeria, Tanzania, Togo, Kazakhstan… We offer batch oil refining systems with capacities from 1 to 30 tons per day. For larger operations, we provide continuous refining plants with capacities of up to 500 tons per day.

If you are interested in setting up an edible oil refinery or would like more information about our equipment, please feel free to contact us. Our engineers will work with you to provide a suitable solution based on your production needs.

Chemical Refining Process

1. Water Degumming: Using water to hydrate crude oil and remove phospholipids (gums). It is effective for oils with a high gum content, and it helps to improve oil quality before further refining. It also generates a valuable by-product — lecithin, which is widely used in the food, pharmaceutical, and feed industries as an emulsifier and nutritional additive.

2. Alkali Neutralization: This is a critical stage that defines the chemical refining process. An alkaline solution (usually NaOH) is added to neutralize free fatty acids (FFA). This reaction forms soapstock, which can then be removed by centrifugation or settling. It reduces acidity, improves flavor, and helps stabilize the oil.

3. Washing: After alkali neutralization, washing with water removes soap, impurities, and residual alkali from the oil. This step helps improve purity and prevents soap formation during further refining.

4. Bleaching: Using bleaching earth or activated carbon to remove pigments, oxidation products, and impurities to improve oil appearance and stability. This step makes the oil lighter and clearer.

5. Dewaxing: Dewaxing removes waxes and saturated fats from the oil, improving its clarity and preventing solidification at lower temperatures. This is particularly important for oils like sunflower or palm oil.

6. Deodorization: Deodorization is done under high heat and vacuum conditions with steam to remove volatile compounds and undesirable odors. It helps improve the taste, smell, and overall quality of the oil.
