Edible oils can be refined by either a chemical or a physical refining process. Chemical refining is still the most widely applied process for soft oils with low free fatty acid (FFA) content (soybean oil, rapeseed oil , sunflower oil etc.). The main by-product of chemical refining is named soapstock, which is a mixture of fatty acid soaps, salts, phospholipids, impurities and entrained neutral oil. Soapstock is usually split with sulfuric acid, resulting in a low value, difficult-to-valorize “acid oil” and a difficult-to-treat wastewater stream. The high neutral oil losses in the soapstock (especially when crude oils with higher FFA and phospholipid contents are chemically refined), the low value of the resulting acid oil and the stricter environmental legislation(making wastewater treatment more expensive) are the main reasons for oil processors to consider physical refining. On the other hand, chemical refining is a quite forgiving towards crude oil quality and it usually gives a good refined oil quality. For these reasons, it is still the preferred refining process for many processors, and it is not expected that chemical refining will disappear . Hence, there will remain a serious interest in new developments that make chemical refining more attractive.
Edible oil refinery can remove the phospholipid, FFA, pigment, peculiar smell and other impurities in the crude oil, it includes degumming, deacidification, bleaching , deodorization, dewaxing . Our company can provide best oil refinery technical skill and equipment for you (1t/d - 500t/d), and we also can flexible adopt physical refinery or chemical refinery according to different crude oil products, let the refined oil with best quality and price.
1. Degumming and deacidification: The gum and acid in the oil will moved in this step. There are different ways to process it. The physical way is suitable for low acid oil and big capacity, while the chemical way is suitable for the small capacity and high acid oil.
2. Decolorization: The white clay is used to move the color of the oil. For different market, people like different color oil, so you can control the color by the quantity of the white clay.
3. Deodorization: The oil will have the special smell of the oilseeds. It also contains the smell of white clay, so we need more the smell which people don't like. The high temperature steam is used to move the smell of the oil.
4. Winterization: There are much wax in the rice bran oil, so the winterization part is needed to move the wax in the rice bran. After moving the wax, the oil can keep clear in low temperature
1. The key to buy the oil refining plant is if you find a professional manufacturer. If they have experience on the oil project? If they are responsible? If they know different kinds of oil material very well? If They can provide perfect after-sale service? They are manufacturer or trader?
2. There are relevant regulations of oil in the CAC (Codex Alimentarius Commission). If you can get the qualified oil which meet the needs of regulations.
3. During operation, if some small parts have problems, we will send the replaced parts to buyers by air within 5 days after notified. This is our after-sale service. But some other irresponsible sellers ignore these problems and refuse to help customers, just because of the high express fee.
4. We will pay a return visit every month, to help them find and resolve any problems.
5. The main equipment all use famous brand. They are including vacuum pump, gear oil pump, conduction oil furnace, valve, air compressor etc.. Our coils and tanks were tested with pressure before delivery.
IV. For installation: We will send technicians to install and adjust the machines ,and also responsible for the training of the buyer's workers. The buyer should be responsible for the each of our technician's accommodation,meals,round-trip tickets, correspondence fee, self-security and 80USD per day each person abroad.
