How to extract edible oil from maize?

In fact, maize oil is also called corn germ oil, which is extracted from corn germ. Only the corn germ contains oil, and the other part is corn starch. In this article, we will explore the steps involved in extracting edible oil from maize, including obtaining, cleaning, flaking the raw material, and extracting oil.

Step 1: Obtaining the raw material

As one of the products of corn starch factory, corn germs can be obtained directly from corn starch factories. It is important to choose maize/corn germ that is fresh and free from any mold or contaminants. The quality of the raw material will have a direct impact on the quality and flavor of the extracted oil.

Step 2: Cleaning

Before extracting oil from maize, it is essential to clean the maize thoroughly. This helps remove any dust, dirt, or impurities that may be present on the grains, ensuring a clean final product. DOING group supplies three different types of cleaning machines you can choose from.

Step 3: Flaking

The raw material can be pressed into embryo pieces through the flaking roll, which increases the contact area between the maize and the maize oil extraction machine and improves the oil yield.

Step 4: Extracting the Oil

There are several methods for extracting oil from maize, with the most common being solvent extraction or mechanical pressing. In solvent extraction, a solvent such as hexane is used to extract the oil from the maize germ. The solvent is then removed from the oil through evaporation, leaving behind pure maize oil.

Mechanical pressing, on the other hand, involves using a mechanical press to squeeze the oil out of the maize germ. This method is more traditional and the residual oil rate is higher than the first method.

HENAN DOING provides these two types of maize oil extraction machines. The former is suitable for large processing volumes (above 20TPD), and the latter is suitable for small and medium processing volumes. If you have needs, please leave us a message. Our professional project manager will give you suggestions.
