There are many types of raw materials that can be squeezed by the screw oil press. Rapeseed, peanut, soybean, sesame, sunflower, and flax are relatively common oils. The color of the oil squeezed from different oils is different.
Whether it is processing or selling oil, ordinary people like the color of the oil they squeezed to look better. Generally, the color of oil is mainly golden. Some customers report that the color of the peanut oil pressed by the screw press is black?
There are two processes for pressing the peanuts with the screw oil press, one is cooked and the other is raw. Raw squeezing is to squeeze directly without frying seeds. The color of the oil is maintained, so the squeezed oil is relatively golden. Nowadays, more and more people recognize that raw squeezing can well preserve the operating cost of peanut oil. A major advantage of raw squeezing is that the color of the squeezed oil is clear and beautiful.
The cause of peanut oil blackening
The black color of the peanut oil pressed by the screw press is mainly for the cooked pressing. Cooked squeezing requires fried seeds. Peanuts often have a red coat. The red coat will be charred during the process of frying the seeds. Some novices can’t grasp the problem of small fire, so it is easy to burn the seeds when they are fried. The skin of the fried peanuts is black, so the color of the squeezed oil will also be black.
The solution to peanut oil blackening
The main solution is to use a closed seed frying machine. The closed seed frying machine is both steamed and stir-fried, which can retain the moisture in the peanuts well, so it is not easy to fry the seeds when they are fried. The color of the peanut oil squeezed out in this way is relatively good-looking. Whether it is raw or cooked. The crude peanut oil that is squeezed out needs to be filtered to filter out the impurities in the oil, so that you can get good-looking peanut oil.
