What are the sections of the cooking oil processing line?

Cooking oil is a staple in kitchens worldwide, playing a crucial role in culinary endeavors and everyday meal preparation. Behind the scenes, the production of cooking oil involves a meticulous process that transforms raw materials into the familiar and essential product we use daily. The cooking oil processing line is a series of interconnected sections, each playing a vital role in ensuring the quality, purity, and safety of the final product.

1. Seed Preparation Section

The journey of cooking oil begins with the selection and preparation of the raw materials, usually oilseeds such as soybeans, sunflower seeds, canola, or palm fruits. In this section, the seeds undergo cleaning, sorting, and conditioning processes to remove impurities, dust, and unwanted particles. The goal is to provide a clean and uniform seed base for the subsequent extraction processes.

After cleaning, the seeds also need to be broken, softened, flaked, etc. Because seed size and moisture content will affect seed oil yield. Different seeds require different pretreatment processes. Henan DOING Company will provide you with different seed pretreatment machines to ensure maximum oil yield.

2. Oil Extraction Section

The heart of the cooking oil processing line lies in the oil extraction section. Various methods are employed, including mechanical pressing, solvent extraction, or a combination of both, depending on the type of oilseed. Mechanical pressing involves physically squeezing the oil out of the seeds, while solvent extraction utilizes chemical solvents to dissolve and extract the oil. This section is pivotal in obtaining the maximum yield of oil from the seeds.

If your daily processing capacity is less than 20 tons, you can choose mechanical pressing method, otherwise, choose solvent extraction. We can supply these two different cooking oil production line machines.

3. Oil Refining Section

This oil refining section is also an important section of cooking oil processing line, which can refine crude oil into edible oil with national food standard. The extracted crude oil undergoes refining to remove impurities, undesirable flavors, and odors. The refining section typically includes degumming, neutralization, decolorization, and deodorization processes. Degumming removes phospholipids, neutralization addresses free fatty acids, decolorization eliminates pigments, and deodorization removes volatile compounds responsible for off-flavors and odors. The result is a clear, colorless, and odorless refined oil ready for consumption.
