What materials can be refined by palm oil refining machine?
In order to remove impurities and harmful substances in crude palm oil and improve the oil quality and market competitiveness, more and more investors choose to purchase palm oil refining machine to refine the obtained crude palm oil. In fact, the function of palm oil refining machine is not limited to this, it can achieve multiple purposes.
The palm oil refining machine can not only refine crude palm oil and palm kernel oil, but also refine the crude oil pressed by conventional oil seeds such as soybean, rapeseed, peanut, sunflower seed, sesame, castor bean, corn germ, etc. Because the refining processes of palm oil and oil pressed by conventional oil seeds are similar, they all need to go through the following four steps:
The refining processes of crude oil
①Degumming:
The mucilaginous impurities contained in the crude oil will have a certain impact on the oil stability. We can use the method of water-degumming to remove such impurities. That is, using the hydrophilicity of mucilaginous impurities, adding hot water or pumping water vapor into the crude oil to remove them.
②Deacidification:
Free fatty acids affect the stability and flavor of oils and fats, and free fatty acids can be removed by neutralizing them with alkali.
③Decolorization:
Crude oil contains chlorophyll, carotenoids and other pigments. Chlorophyll is a photosensitizer and affects the stability of oil, while other pigments affect the appearance of oil. We can add white clay adsorbents to remove these pigments, making the oil color brighter.
④Deodorization:
There are some unwanted odorous substances in the crude oil, mainly due to the oxidation of the oil. The method of vacuum distillation is adopted, and citric acid is added to chelate excessive metal ions and inhibit oxidation.
The oil obtained through the above refining process is more in line with the national edible oil standard, and has higher edibleness and market value.
