Peanut oil is most common used cooking oil in the world, In order to get peanut oil , the peanut oil mill machinery is necessary. Henan Doing Company , as a professional manufacturer of peanut oil mill machinery, we can supply peanut oil mill machinery with different capacity. And our peanut oil mill machinery have exported to many countries in the world. The whole set peanut oil mill machinery includes peanut oil pretreatment and pre-pressing machine, peanut oil solvent extarction plant and peant oil refinery plant. Next i will introduce the complete peanut oil extarction process.
Peanut oil mill machinery
How to make peanut oil from peanut ? How to extract peanut oil form peanut ? What is the steps of peanut oil extraction process?
Peanut oil mill machinery starts with peanut, peanut oil content 44-55%. Compared with other common oilseeds, there're three main sections of peanut oil mill machinery, including prepressing/pressing/pretreatment section, solvent extraction section, and refinery section.

Pre-pressing section of peanut oil extraction process:
Husker: if we press the peanut with shell, the shell will take away the peanut oil, so we need to separate the shell with nut first, then go to the next section.
Cleaning Sieve: Use vibration cleaning sieve to get better cleaning effect. This step is mainly to clean the big impurities in the peanut oil extraction process;
Gravity destoner machine: to remove stones in nut, to avoid the stone destroy the penaut oil press machine and other peanut oil machine, and also can get qualified product oil .
Magnetic selector: to remove the iron in the peanut. Crushing: Peanut belongs to big size oil seed, so it need be broken down to small pieces. The function of the crusher in peanut oil pretreatment production line is to increase the area of oil seed and make the tempering easier. The peanut is divided to 6-8 pieces and the water content of crusher is 7-12%.
Flaker: after crushing process, we need to flake the crushed peanut , which make the cell wall of peanut broken . And we flake the peanut to 0.55 mm thickness. Then it is useful for the oil cooking.
Cooking machine: after flaking process, we need to cook the flaked peanut , control the moisture at 5-7% , the temperature is 110-115degree, which will help to make the oil into the surface, which will also add the final product flavor.
Peanut oil pretreatment and pressing machine
After peanut oil pre-pressing process, we get two parts: the pressed peanut cake and the crude peanut oil. In normal conditions, The pressed peanut cake will be send to peanut oil solvent extraction plant for further processing. The crude peanut oil will be pumped to peanut oil refinery plant to refine to high quality peanut oil.
Peanut oil solvent extraction process is the second step in penaut oil extraction process. Product (cake from penaut oil pretreatment section) is carried into peanut oil solvent extraction plant.There are still much oil in cake.Solvent sprays onto cake so that cooking oil can be easily extracted. Then we can get high yield cooking oil .
For the peanut cake from peanut oil extraction plant, will be used as animal feed, we can also provide you palleter to make animal feed. [Recommend reading : Oil solvent extraction plant ]
Peanut oil solvent extraction plant
Main process of peanut oil solvent extraction plant：
Solvent extraction system→D.T.D.C system→Condenser system→Recovery system
Peanut oil erefinery process is the final step in penaut oil extraction process. The crude peanut oil from above mentioned workshop( peanut oil pretreatment workshop and peanut oil solvent extraction workshop), will be pumped into penaut oil refinery units to produce cooking oil at various grades.These peanut oil refinery processes include de-acidification (removing free fatty acid), degumming, decolorization (bleaching), deodorization. Then you can get first grade peanut oil. After we get the refined peanut oil, we will use the oil filling machine to pack the refined peanut oil into bottles or into barrel.

Peanut oil mill project is the ideal investing item with little investment, high production efficiency and high profits! Anyone who need to start penaut oil production business, need to buy penaut oil mill machinery , please contact us! Peanut oil introduction:
Peanut oil introduction:
Peanut, also called groundnut, it’s the most common oil seeds in the world. Peanut is generally distributed in Asian, Africa, and South American, and these places peanut capacity consist of 99% of the world capacity.
Peanut oil yield rate is 40%-50%. After the peanut is pressed or extracted, we can get the light yellow, clear and transparent peanut oil, which is a kind of edible cooking oil easily digestible for human beings. The oil is available with a strong peanut flavor and aroma, analogous to sesame oil. It is often used in Chinese, South Asian and Southeast Asian cuisine, both for general cooking, and in the case of roasted oil, for added flavor.
