It depends . Continuous extractor takes 24 hours while the tank extractor tank batch refining takes 8 hours.
Soybean: 15% to 26%
Sesame: 45% to 63%
Rice bran: 14% to 24%
Sunflower seeds: 29% to 30%
Cottonseed: 16% to 22%
Peanuts: 45% to 50%
Sunflower seed oil, rice bran oil, corn germ oil, tea seed oil
Refined oil meet the first grade quality indicator of China's vegetable oil standard.
Cakes, phospholipids, oil feet, soap feet and fatty acids.
The land area typically depends on the capacity of the plant. We can suggest an appropriate space to prepare after given specifications, or, can design the oil plant in-house specifically to the amount of work space available.
1. Crude oil contains impurities, and it's oxidized and deteriorated easily which means long-term storage is difficult.
2. There may be harmful substances in the crude oil.
3. When heating crude oil, there are many bubbles, smell, fumes which obviously affect the smell and taste of food.
Mainly contains the following sections: deacidification degumming, decolorization, deodorization and dewaxing.
Different types of oil refining process is different. For example, soybean and rapeseed oil does not require dewaxing while sunflower seed oil does.
The advantage of leaching is following: the meal contains less residual oil, high oil yield, cost low, high economic efficiency, and high quality of meal for the feed industry.
High oil content materials such as peanuts, sunflower seeds, rapeseed are suitable for pre-press leaching. Materials with low oil content such as soybeans is suitable for direct leaching.
Normally we use N-hexane as solvent.
Less than 1%.
Solvent residue in leaching oil is less than 100PPM and refined oil doesn't contains solvent residue.
