Edible oil refining is a very important process to produce first grade edible oil. According to the different usages and requirements, utilizing the physical methods to get rid of the harmful impurities and needless substance from the crude oil, and then you get good quality refined oil.
For common vegetable oil refinery plant, it includes four processes: degumming, deacidifcation, decolorization and deodorization. While for the palm oil refinery plant, we designed the Dry-degumming process Full Continuous Refining method. In this method we combine degumming process together with decolorization, and combine deacidification with deodorization. This refinery process has advantages of: low cost, less civil consumption, less oil lost and more steady quality of refined palm oil.
1. Continuous decolorization (bleaching)and filtering section
The newly complete continuous decolorization (bleaching) section uses two alternate filters. The mixing oil and earth flow into the Vacuum decolorization (bleaching) tower. The decolorized oil is pumped through the alternate filters. The valves are automatic LDitched. Filtered oil is pumped into deodorization section after safety filters.
2. Continuous Deodorization section
After heating with deodorized oil, the un-deodorized oil is pumped into vacuum heat exchanger to be heated with conduction oil boiler before deodorization system.
Before deodorizer, the heated oil needs to pass through sieve-plate columns, which is specially designed to remove large amount of fatty acid. Right here, the fatty acid amount will reach absolutely low. Some odor material needs long time to be removed, but will be finally removed or inactive in column-plates. The oil reserved in the column-plates has been sprayed a ratio of mixing steam.
1. What our machines can do?
We have pressing machine, solvent extraction machine, and refinery machine, our press/expeller can get cold pressed oil or hot pressed oil from peanut, sunflower seeds, corn germ, cotton seeds, soy bean, rapeseeds and other oil crops; our solvent extraction line can extracte oil from various cakes by solvent(leaching),like soy cake, peanut cake, sunflower cake and others; Our refining machine can help you get refined oil(decoloring oil, degumming oil, deacid oil), 1st to 4th grade cooking oil as your requirements.
The biodiesel machine can produce International standard biodiesel, like EN14214 standard, ASTM 6751-03 standard, DIN V 51606 standard.
2. What's your factory's ability, which kind of machine do you manufacture?
We can produce all kinds of edible oil machinery, which includes palm oil production machine, peanut oil, soybean oil, cotton oil, sunflower oil, corn oil, rice bran oil and other kinds of edible oil.
The whole line includes oil press line, oil extraction (solvent) line, oil refinery line, palm oil fractionation line, sunflower oil dewaxing line, decoloring process, deodorization process and others.
We can produce biodiesel plant/equipment/machines also. On the other hand, our factory developed ourselves, import many advanced technology to strengthen ourselves and ensure our customer's right.
