Peanut Oil Production
Peanut oil (groundnut oil, arachis oil), as a kind of light yellow transparent edible oil with clear color and lecture, pleasant fragrance and good taste, is relatively easy to digest. It is not only widely used in China, South and Southeast Asia, it is also popular in the United States. Peanut oil contains more than 80% unsaturated fatty acids (including 41.2%oleic acid and 37.6%linoleic acid). It also contains 19.9% of palmitic acid, stearic acid, arachidic acid and other unsaturated fatty acids. The fatty acid composition of peanut oil is relatively good, therefore it is easy for human bodies to digest and absorb. (Read more: Oil Extraction Business Plan >>)
Peanut/Groundnut Oil Processing
According to scientific data, the use of peanut oil can make the body's cholesterol into bile acids and excreted, thereby reducing the plasma cholesterol levels. In addition, the peanut oil also contains sterol, wheat germ phenol, phospholipids, vitamin E, choline and other beneficial substances for human. Nowadays many people who plant peanut or have easy access to large quantity of peanut, are interested in peanut oil production. They are looking for the BEST plan to set up edible oil mill plant at low investment cost for high peanut oil manufacturing!
Commercial Peanut/Groundnut Oil Extraction Methods
There are generally 4 methods for peanut oil production: pressing, solvent extraction, aqueous extraction, and aqueous enzymatic method. But the widely used commercial oil extraction methods for groundnut oil production for commerical or industrial use are solvent extraction and mechanical pressing due to the high efficiency of oil production, scientific oil extraction process and relatively cost-effective oil extraction equipment. Here just introduces the basic groundnut oil extraction process using the two peanut oil extraction methods.
Peanut Oil Production Process
Solvent Extraction for Peanut Oil
The solvent extraction plant process is a widely used technique. It is a chemical procedure for extracting oil from the seeds, nuts, and vegetables using a solvent, and usually, Hexane is preferred. Generally, people use the solvent extraction method in industries for edible oil processing, and it is not always followed by pressing. It is a reliable method for separating tons of oil from seeds and other protein meals. The solven process of groundnut oil manufacturing is achieved through the grinding of seeds, preceding solvent flashing. It effectively extracts 99% oil, leaving just 1% oil in the residue. But because of the large and expensive oil extraction machine for solvent plant, this method is not suitable for household and small scale oil production business.

Mechanical Pressing for Peanut Oil
Oil pressing, also called mechanical method, refers to the use of mechanical forces to squeeze oil out of peanut. The mechanical oil pressing method uses the power which is generated from the gradual reduction of the volume between the squeezed screw and the pressing chamber, as well as the power generated by the friction between the material and the machine to extrude the oil inside pretreated peanut. The oil pressing method adopts purely physical squeezing oil producing technology to make oil by the process of material election, roasting, physical pressing and filtering.

The core equipment for peanut oil pressing line is oil press machine. There are three types of peanut oil extraction machines using this methods, including
- Large Screw Oil Press Machine - suitable for large scale peanut oil manufacturing plant and the pre-pressing sector of solvent extraction plant
- Small Screw Oil Press Machine - suitable for medium and small scale groundnut oil production line
- Hydrualic Oil Press Machine - suitable for high quality oil production line or cold pressing line
The peanut oil press machine provided by ABC Machinery has high quality and good production efficiency. Its capacity is 5-200ton/d per set.

In addition, we are a leading oil extraction machine manufacturer in China, buying your peanut oil processing machinery from us can save you a lot of money since all the equipment is guaranteed with factory price!
Required Peanut Oil Production Process
Above is the main peanut oil extraction methods that are widely used in commercial vegetable oil processing plant to improve the oil production efficiency and oil quality. Before starting the peanut oil extraction process, the peanut/groundnut should be pretreated to ensure high oil output. The basic cooking oil production machine for peanut/groundnut processing includes shelling, cleaning, cooking, flaking and more. There are corresponding machines and oil extraction axuliary equipment to help peanuts pretreatment process.
Peanuts Groundnuts Processing Machines
After extracted from the solvent extraction plant or peanut oil extraction machines, the crude peanut oil should be filtered and refined through professional oil refining process to improve the quality.

Popular Peanut Oil Pressing Methods
Divided by pressing temperature, there are 2 types of peanut oil pressing methods: hot pressing technology and cold pressing technology.
|Oil Pressing Methods||Introduction|
|Hot Pressing||Hot Pressing is the traditional process of peanut oil: peanut oil is steamed fried and pressed, usually at a temperature above 120 ℃ with a high rate of oil output. But because of the high production temperature, the peanut protein is usually severely denatured and the lose great mount of nutrients.|
|Cold Pressing||Cold Pressing method refers to the oil production technology which is conducted under 60℃. Before pressing, generally uses the method of removing the red skin, which is beneficial to the reserve of nutrients and the comprehensive utilization peanut protein in peanut oil.|
