The crude oil so obtained from the pressing will be first clarified in a settling tank and then shall be pumped through the oil filter machine. The filtered crude groundnut oil will be pumped to the edible refinery machinery where it shall pass through three stages of refining: neutralization, bleaching and deodorization.
What is groundnut oil manufacturing process?
The groundnut oil manufacturing process consists of two methods: mechanical pressing and solvent extraction. The mechanical pressing method extracts 85% of the oil, while the remaining oil is extracted using the solvent extraction method.
How are groundnuts processed?
After harvesting, groundnuts are received at processing facilities and undergo preparation, pressing, and crude oil refining. Initial processing involves removing foreign objects such as leaves, nodes, and weed seeds.
How is peanut oil extracted by mechanical pressing?
Peanut oil can be extracted using mechanical pressing, which extracts 85% of the oil. The remaining oil is extracted using the solvent extraction method. According to mechanical pressing technology, the peanut oil production process can be divided into three phases: peanuts preparation, pressing, and crude oil refining. During the pressing phase, mechanical pressing is used to extract the oil.
