Palm oil refinery, just as its name implies is used for refining crude palm oil to produce high quality edible refined palm oil. Our company is here to introduce our HOT Sale Small Scale Palm Oil Refinery Machine to you! It is the best palm oil refining equipment for small oil mill. The following is a brief introduction to the refining process and characteristics of small scale palm oil refinery.The small scale palm oil refining plant makes an appealing business venture for investors and the like looking into creating palm oil processing business. It has proved rather advantageous in the booming market of palm oil production.
Our oil refining equipment unit for small scale production has all the bells and whistles including decreased land usage requirements and investment capital. Due to the small size of the equipment set, it is also easy to install and maintain. There are several types of crude oils you can choose to work with including palm oil (CPO), palm kernel oil (PKO) and other types of vegetable oil such as sunflower oil, fish oil, peanut oil, etc.
Degumming: the process to remove gelatinous impurities within crude oils by chemical or physical methods is called degumming. In edible oil, if the content of phosphatide is high, it is easy to blister, smoke and smell when heated. And the phospholipid is oxidized at high temperature and then make the crude oils in dark brown, which affects the flavor of fried food. Based on the principle that phospholipid and some proteins within the crude oils are soluble to oils at the condition of sewage, but insoluble in oil and water after the formation of hydrate, degumming process is to add hot water or steam into crude oils, and heat crude oils, agitation mix at the temperature of 50 ℃. Then let stand for layered, in that way, the phospholipids and part of the proteins are removed from the crude oils.
Deacidification: the Free Fatty Acids (FFA) contained in the oils will affect its stability and flavors. The process to remove FFA is called deacidification or alkali refining.
Decolorizing: crude oils may contain chlorophyll, carotenoid and other pigments. Chlorophyll is photosensitizer, which affects the stability of oil, while other pigments can affect the appearance of oil. So theses pigments can be removed by adsorbent in decolorizing process.
Deodorization: there are some undesirable odor substances in oil, mainly from oil oxidation products. The method of vacuum distillation was used to inhibit the oxidation.
