How is Edible Oil Made
Edible Oil, presses by oil press machine, oil pressing is a method of extracting oil from oil by mechanical force. According to the depth of the oil pressing and the pressure on the material during pressing, oil pressing can be divided into primary pressing and pre-pressing with leaching. This method can be used to extract oil from seeds or nuts such as sunflower seeds, coconuts, peanuts, sesame seeds, soybeans, and rapeseed.
Cooking oill manufacturing is a process pressing raw material to crude oil, then use oil refining machine to get refined oil. Like edible sunflower oil, coconuts oil, peanuts oil, sesame seeds oil, soybeans oil, and rapeseed oil.
Overview of Oil Processing Steps
Oil processing steps can be divided into 5 sections: Cleaning, Crushing, Stir-frying, Pressing and Refining, Packing.
1. Cleaning section
During cleaning, first use a vibrating grading sieve or a primary cleaning sieve to remove impurities such as grain stalks, sand, and large stones.
Generally, the combined cleaning screen are used for small scale oil press machine, such as 5-20 tons per day oil press line.
Then, there is a gravity grading screen is also a stoner, which cleans the small stones of oil seeds again to ensure the cleanliness of the raw materials. The principle is to use the different weights of impurities and oil seeds. And for the large capacity oil processing line, there are vibrating screen and gravity classifier, even magnetic separator.

2、Crushing: Crushing oil crops into particles or powder suitable for pressing.
3、Pressing/Extraction: The next step involves pressing or extracting the oil:
Mechanical Pressing: Uses mechanical force to extract oil from seeds or fruits with high oil content.
Chemical Extraction: For seeds with low oil content (e.g., soybeans, rapeseeds), extraction is done using chemical solvents like hexane to increase yield.Get Details
4、Refining: After extraction, the oil may contain impurities, pigments, and undesirable flavors, so it undergoes:
Impurity Removal: Solid impurities are removed through precipitation or filtration.
Bleaching: Adsorbents like activated carbon are used to remove pigments.
Deodorization: Steam distillation or other methods remove odors.Get Details
