Peanut oil refinery plant is a set of machines, with which we can get standard edible peanut oil for cooking. In the production process of peanut oil refinery plant, we utilize the physical methods and chemical processes according to the different usage and requirements to get rid of the harmful impurities and needless substance in the crude peanut oil.
Refining Process of the peanut oil refinery plant

1>Degumming：Degumming removes gums as preparation for subsequent refining processes.
2>Deacidification：Deacidification removes FFA (free fatty acid) in crude oil.
3>Decolorization: Decolorization removes pigments in crude oil by adding white clay, which can improve the oil quality.
4>Deodorization : Deodorization removes odor in crude oil, which can improve the flavor, stability, color and quality of the oil.

Peanut oil refining process detailed description

Groundnut oil is usually refined by the alkali neutralization process.For alkali refining following processing step takes place:

Gums Conditioning & Neutralization

• Alkali Refining Process

The crude oil is neutralized as a first process, that primarily involves the treatment of crude oil with an alkali. Soap separation follows in order to remove soap from the oil. Hot water is subsequently employed to wash the soap-separated oil to remove the soap traces from the oil followed by a drying process to evaporate the moisture of the oil.

• Gums conditioning & Neutralization

Groundnut oil is first treated with citric acid and followed by caustic soda lye to neutralize the fatty acids and condition of phospholipids. The neutralization reaction produced the sodium salt of fatty acids which was removed through the centrifugal separator and clean oil washed with hot water to remove the traces of soap.

• Washing

Neutralized oil was treated with hot water and separated through the centrifugal separator to remove the traces of soap from the neutral oil.

• Drying

Removal of moisture under vacuum.

Bleaching

“Bleaching” is a process of selective removal of pigments and impurities by the physical and chemical interaction of an adsorbent with an oil or fat to improve its quality.

This process refers to the art of removing :

• Colour pigments

• Dirt, Trace metals

• Removal of polycyclic Aromatic compounds

• Phospholipids

Mectech provides a wet bleaching process in its Groundnut Oil Processing Plant which has shown better results with a lesser amount of bleaching clay.

Deodorization

Deodorization of Groundnut oil is a vacuum stripping process in which a given amount of stripping steam is passed for a given period of time through hot oil at a low pressure which removes various volatile components and fatty acids to increase the self-life and maintained good odor-free test of the product.

Deodorization is a Multi-Step Process Comprising :

• Deaeration

• Heating

• Deodorization cum De-acidification

• Cooling

Features of peanut oil refinery plant

• High-quality oil

The groundnut oil process used in a refinery plant ensures that the oil is of high quality and free from impurities. The extraction machines used ensure maximum yield and minimum waste, resulting in pure and healthy oil.

• Longer shelf life

Refining groundnut oil extends its shelf life, making it more stable and resistant to oxidation. A high-quality groundnut oil extraction machine enhances the oil's overall quality, making it ideal for long-term storage.

• Increased profitability

Setting up a groundnut oil refinery plant for the groundnut oil process can be a lucrative business venture. The high-quality oil produced attracts a premium price, and the efficient extraction machines used in the process reduce production costs, increasing overall profitability.

• Health benefits

Refined groundnut oil is a rich source of healthy fats, vitamins, and antioxidants. These nutrients have various health benefits, including reducing inflammation, improving heart health, and supporting brain function.
