The technological process of oil press

General oil pressing processing is very simple. Most of them are dual-purpose machines for peeling and screening, as well as a frying machine and an oil press. There are also those that only use an oil press. But here is an introduction to why we need to perfect the process. However, oil extraction is divided into heated oil extraction and cold pressing processes. Cold pressing has a low oil yield, while hot pressing has a high oil yield. However, if the hot pressing is not performed well and the oil is overheated during the frying process, the color of the oil that comes out will be darker. But it tastes delicious.

In fact, if you want high quality oil, you must refine it. The purpose of oil refining is to remove impurities and process the extracted oil. This includes four processes: gum removal, acid neutralization, deodorization, and color removal. But as a small-scale oil press user, it doesn’t have to be so complicated at all. The purpose of removing colloids and neutralizing acidity can be accomplished in a small refinery.

What is the function of removing gum? Colloid is what adds color to the oil and makes it foam easily when used. So this problem can be solved through this process. The processed oil is of better quality and looks better, and can also remove substances harmful to the human body. Therefore, the small oil refinery is a very important machine for improving the quality of oil output.

So the oil pressing production line is: peeling and screening dual-purpose machine → frying machine → oil press → small oil refiner
