Hydration Deguming & Alkali Refining Deacidification Process
Neutralization: the crude oil is output by the oil feed pump from the oil tank, and next enters the crude oil heat exchanger to recover part of heat after metering and then is heated to the required temperature by the heater. After that, the oil is mixed with the metered phosphoric acid or citric acid from phosphate tank in the gas mixture (M401), and then enters the conditioning tank (R401) to make the non-hydratable phospholipids in oil change into the hydratable phospholipids. Add the alkali for neutralization, and the alkali quantity and alkali solution concentration depend on the quality of the crude oil. Through the heater, the neutralized oil is heated to the temperature (90°C) suitable for centrifugal separation to remove the phospholipids, Auxiliary Machine For Oil PressA and other impurities in the crude oil. Then the oil goes to the washing process.
Washing: there is still about 500ppm soap in the neutralized oil from the separator. To remove the remaining soap, add into the oil about 5~8% hot water, with water temperature 3~5 °C higher than the oil generally. To achieve more stable washing effect, add phosphoric acid or citric acid when washing. The re-mixed oil and water in the mixer is heated to 90-95°C by the heater, and then enters the wash separator to separate the remaining soap and most water. The water with soap and oil enters into oil separator to separate out oil in the water. Further catch the oil outside, and the waste water is discharged to the sewage treatment station.
Vacuum drying stage: there is still moisture in the oil from the wash separator, and the moisture will affect the stability of the oil. So the oil at 90°C should be sent to vacuum drier to remove the moisture, and then the dehydrated oil goes to the decoloring process. Finally, pump out the dry oil by canned pump.If you are interested in our company,please feel free to contact Ms. Myra for a quotation,(Tel/whatsapp:0086-18363092712, Email:[email protected],Skype:leaderfoodmachine2).You will get superior service,and Shandong Leader Machinery Co.,Ltd. produce CE proved hot & cold oilseeds pressing machine, vegetable seed oil processing plant with high quality, high performance and the best prices.
Continuous Refining Decoloring Process
The main function of decoloring process is to remove oil pigment, residual soap grain and metal ions. Under negative pressure, the mechanical mixing method combined with steam mixing will improve the decoloring effect.
The degummed oil firstly enters into the heater to be heated to the appropriate temperature (110°C), and then goes to the bleaching earth mixing tank. The bleaching earth is delivered from the low bleaching box to the temporary tank by wind. The bleaching earth is added by automatic metering and is interlockingly controlled with the oil.
The oil mixed with the bleaching earth overflows into the continuous decolorizer, which is stirred by non-powered steam. The decolored oil enters into the two alternate leaf filters to be filtered. Then the filtered oil enters the decolored oil storage tank through the security filter. The decolored oil storage tank is designed as the vacuum tank with the nozzle inside, so as to prevent the decolored oil contacting with the air and influencing its peroxide value and color reversion.

WHAT OILSEEDS ARE AVAILABLE?
ABOUT HOT PRESSING AND COLD PRESSING:
Hot pressing refers to a kind of press technology which is applied to heat in conjunction with mechanical pressure.
It is applied for lower oil content oilseeds, such as soybean, sesame etc. In oil mill plant, hot pressing is to heat the oilseeds, using technical hot pressing machine, which raise the temperature of oil seeds before pressing, so as to improve oil yield. It is the most popular method of pressed oil nowadays.
Cold pressing refers to another kind of press craft which can squeeze oil from oilseeds directly without extra heat or chemical treatments.
No need additives for cold press, produces is safe, healthy and non-pollution. After pressing, the natural nutrition wouldnât be damaged.
The deformation of protein in cake which has been produced by low temperature pressing, and it is smaller than being produced by high temperature pressing.
In addition, the cake coming from cold pressing can be used as the source of high quality protein power. Instead of hot pressing, cold pressing keep more nutrients of oil esp. vitamin E and the rate of chemical action is the least in the oil press. That is why cold pressing oil is much more expensive than hot pressing oil, though hot pressing can increase oil yield.
DIFFERENCES BETWEEN COLD AND HOT PRESSING:
Cold pressed oil:
a) Keep the natural features, like taste, flavor, color;
b) Avoid the negataive influences from the tranditional hot press method;
c) The physiological activator (vitamin E, sterol, etc) are preserved completely;
d) Not all the oil seeds suit for cold press, here are the different flavors for varios seeds below:
e) The raw materials must be well-selected, or it'll affect the cold press oil.
Hot pressed oil:
aa) The color of the pressed oil is darker, the acid value rise quickly;
bb) The crude oil must be refined, then it can be edible;
cc) The bioactivator are lost under high temperature when it's pressed.
