Leaching, also called extraction. Extraction is an essential part of the oil production process.The extraction method is a kind of oil production process. Using oil and organic solvent mutual dissolution properties, the oil is crush-pressed into a green sheet or puffed, and then contacted with an organic solvent such as n-hexane and an oil green sheet in a device called an extractor. The oil in the oil is extracted and dissolved, and then the solvent in the oil is removed by heating and stripping. The crude oil thus obtained undergoes further refining to become the final edible oil.
There are three commonly types to make peanut oil extraction:
1> leaching tank
For daily production of 1-15 tons, the equipment can be operated intermittently and can be produced at any time.
2> Rotocel Extractor
For daily production 15-500 tons, the equipment is continuously produced and has a high degree of automation. It requires that the stock of raw materials can be produced for at least one month, which is beneficial to the reduction of production cost.
3> Loop-type extractor
For daily production of 500 tons or more, the equipment is continuously produced and has a high degree of automation. Ring leaching equipment is mainly designed for large-scale oil leaching processing plants.
