What is refined palm oil? How to make RBD palm oil?

Palm oil is an edible oil obtained by processing palm fruits. It has a wide range of uses and strong market demand. Together with soybean oil and rapeseed oil, it is known as the "three major edible oils in the world". The growing demand has attracted many people who want to work in the palm oil production industry, so many people want to know what palm oil is and what kind of palm oil can be eaten.

Edible palm oil, also known as refined palm oil, is based on crude oil to remove free fatty acids, excess moisture, pigments and unpleasant odors in crude oil. The resulting refined oil can be eaten directly or used in the food industry. How to get refined palm oil? The main steps are degumming, deacidification, decolorization and deodorization. Deacidification is the removal of free fatty acids from hair oil. This is the most critical stage in the entire refining process. Alkali refining method, that is, using alkali to neutralize free fatty acid, so that free fatty acid produces saponin and separates out from oil. Decolorization, adopt adsorption decolorization method to remove the pigment in the crude oil. Deodorization, deodorization can not only remove the odorous substances in the crude oil, increase the smoke point of the oil, improve the flavor of the oil, but also effectively remove pollution. The high-temperature grease is separated, and the odor is drawn away with the steam to achieve the purpose of deodorization.

The palm oil obtained through the above steps has reached the food grade standard. As a professional manufacturer of edible oil equipment, we can provide a series of equipment for palm oil crude oil and refined oil production, welcome your consultation!

Process of crude palm oil refinery machine plant
As above mentioned, palm oil refinery process mainly has four steps, including degumming, deacidification, decolorization, deodorization.

Palm oil refinery process

Introduction of four sections in small scale crude palm oil refinery machine :

1. Degumming Section: Some impurity, such as Phospholipid, gum, and protein, can be dissolved  into oil when there is no water, but once there is water in oil, these impurity can be dissolved into water. So, in degumming section, we use the hot water to wash crude oil for two-three times to remove these impurity.

2. Deacidification Section: Crude oil contains much free fatty acid, which is harmful for health. Free fatty acid can have the reaction with caustic soda, during the reaction, it can be saponified and becomes soapstock, then small soapstock pellets will sink and  becomes sediment and be pumped out. After deacidification, most of the free fatty acid will be removed out.

3. Decoloriztion Section: Most of the crude oil has deep color because of the pigments, such as carotene, xanthophyll, etc. We use bleaching earth to remove pigments, because bleaching earth has strong adsorption capacity. Then pump oil into plate filter to  remove bleaching earth, then pigment also will be removed out along with bleaching earth, then oil will be clean and transparent.

4. Deodorizing Section: Pure oil has no smell, but different crude oil has their special smell because of some volatile matters, for example the oxide for ketones, aldehydes, hydrocarbons. In deodorizing section, we deliver steam into oil continuously, and make  sure steam and oil can fully contacted under high temperature and pressure, then volatile matters can be removed out along with the steam.
