What Steps Are Involved in Peanut Oil Processing?

Peanut oil is a commonly consumed oil in daily life, known for its bright color and nutritional benefits, making it popular among many people. The peanut oil sold in supermarkets is generally divided into pressed peanut oil and extracted peanut oil. Pressed peanut oil is produced using oil presses, while the extraction process uses solvents to extract the oil. These two processes are the most commonly used in oil factories today.

Today, the peanut oil extraction engineer from Henan Huatai Oil Machinery will introduce the peanut oil extraction process in detail.

Peanuts have an oil content of over 40%, making them a high-oil crop. The flavor of peanut oil is very popular, so most oil factories use the pressing process to produce peanut oil. The subsequent processes can turn it into fragrant peanut oil or pressed peanut oil. The production of peanut oil in oil factories involves multiple steps from raw materials to oil, including cleaning, de-stoning, crushing, softening, rolling, steaming, pressing, filtering, and refining. 

These processes serve the following purposes:

1. Cleaning and De-stoning:

This step removes stones, sand, plant stems, and other impurities mixed in during peanut harvesting, transportation, and drying. It not only improves the quality of peanut oil but also prevents equipment wear and tear caused by impurities.

2. Crushing, Softening, Rolling:

Crushed peanuts are softened to enhance their flexibility and reduce powder formation during rolling. Rolling turns peanuts into thin flakes, changing their structure, increasing surface area, shortening the oil path, and facilitating oil extraction.

3. Cooking:

This step adjusts the temperature and humidity of the peanut flakes, making them more suitable for oil extraction by the oil press. Steaming also contributes to the aroma of peanut oil, making the pressed peanut oil more fragrant.

4. Pressing and Refining:

Pre-treated peanut flakes are pressed by the oil press to obtain crude peanut oil. Depending on the required quality grade of the peanut oil, corresponding refining equipment and processes are configured. The crude oil is refined to remove impurities, resulting in finished peanut oil.

This is the peanut oil extraction process. The configuration of the peanut oil production line needs to consider various factors such as the size of the investor's plant, production capacity, quality, and budget. Equipment configuration plans and quotations are provided as needed. The manufacturer has been focusing on the research and production of oil machinery for many years, producing high-quality equipment with a complete range of types and models, offering customized services and production line configurations as needed.
