Corn can be extracted for oil, not the whole corn, but the germ of the corn can be extracted for oil. Corn consists of three parts: the seed coat, the endosperm and the germ. The endosperm is rich in nutrients and can be processed into corn grits, corn starch, corn starch sugar and other products.
Corn itself has a very low oil content, and most of the oil is found in the corn germ, which is about 35% of the average corn germ, so the corn germ in the corn embryo is an excellent choice for extracting corn oil.
Corn embryo extraction is a very important link, the quality of the germ will affect the oil yield and the quality of the oil, corn processing plant can according to the corn embryo and endosperm resistance to crushing ability is different, firstly, the endosperm is crushed by the pressure rolling equipment, and then the corn embryo is sifted by the sieving equipment. The effect of separation in this process may not be ideal, and need to be separated several times, so that the content of impurities in the corn germ reaches the standard we need.
Special attention should be paid to the fact that since germ is only 10-14% of corn, it means that getting 10 tons of germ per day requires processing 100 tons of corn, which is a significant investment. If your business is in its start-up phase, we recommend that you buy corn germ directly from the market or from a corn processing plant.

Rice bran oil is a kind of healthy oil rich in gluten, the crude oil contains more complicated and more quantity of oil-soluble substances than other vegetable fats and oils, which makes it difficult to refine rice bran oil, and the loss of neutral oil in the refining process is serious.

Rice bran is the by-product of rice processing, usually the production of rice bran actually consists of rice germ and rice bran, is edible grade rice bran, due to the processing of rice bran raw materials and the processing technology used is different, so the composition of rice bran is not exactly the same.

Physical pressing is a common method of extracting edible oil, so how to improve the oil yield of oilseeds in the physical pressing process?

The first thing we need to do is to choose better quality oilseeds, do a good job of pre-treatment of oilseeds before pressing, and choose a suitable edible oil press.
