Oil refining is divided into physical methods, chemical methods and physical chemistry methods. For a certain crude oil, which methods should be used in the refining process, generally depends on the quality of crude oil, the application of refined oil, refining process budget and advanced nature of equipment, and both the refinery machine and entire oil refining line are available from us to do physical & chemical refining. The complete edible oil refining process mainly includes filtration, degumming, deacidification, vacuum dehydration, decolorization, deodorization, dewaxing and polishing filtration.
Please note: for self-employed entrepreneur and small-business owner, 1-10 tons/day batch type oil refinery production line is their best choice to refine crude oil into the first or second grade edible oil(e.g. peanut oil, rapeseed oil, tea seed oil, soybean oil, sunflower oil, etc.) with features of multi-purpose, easy transportation, small footprint, fewer operators and energy-saving.
Main Steps of Oil Mill Refinery
crude oil refinery processing steps
4. Vacuum Dehydration
8. Filtration and Storage
Impurities Removed in Each Refinery Processing Step
|Refining process||Removed impurities|
|Filtration||suspended particulate impurities and other mechanical impurities.|
|Degumming||phospholipids, sugar, protein and trace metals|
|Neutralization||free fatty acids, phospholipids, pigments|
|Decolorization||pigments, oxide, trace metals, waste clay, gum|
|Deodorization||free fatty acids, odorous substances|
|Polishing filtration||residual trace insoluble|
Structure Features of Batch Type Oil Refining Production Line
1.The batch type oil refining line is cut by plasma CNC cutting machine and welded together by automatic welding equipment. The weld has a uniform forming and exquisite appearance which can reach customer satisfaction. Tight structure and small footprint.
2.The entire production line is made of food-grade stainless steel and through polishing process. Long service time and conform to national food machinery standards.
3.The machine uses the heating coil as a heat source. Small size, compact structure, high heat transfer efficiency, good mechanical strength, good adaptability and high refining rate.
4.The machine is equipped with ball valve, which has small fluid resistance, strong abrasion resistance, good sealing performance, long service life.
5.The operating data are all displayed by the instrument, automatic measurement, and control for temperature, pressure, flow and liquid level, simple & safe operation. The ordinary staff after telephone training can work on the machine.
6.The small oil refining production line can achieve oil dephosphorization, dealkalization, dehydration function, and it can also achieve constant temperature decolorization according to users.
7.The oil heating furnace has the strong adaptability to fuel, the fuel can be rice husk, firewood, coal, etc. Less investment and good effect.
Applications of 1~10T/D Oil Refining Equipment
1.Suitable for factories with small yields, and the production line capacity is made according to users.
2.The 1~10T/D oil refining equipment can process various type of oil, such as peanut oil, soybean oil, coconut oil, sunflower seed oil, sesame oil, palm kernel oil, hemp seeds oil, castor seeds oil, mustard seeds oil, rice bran oil, rapeseed oil.
3.The oil refining equipment can work independently or together with the entire oil production line, and we provide services for on-site installation, debugging and training.
