LD automatic high performance refined sunflower oil machine
Products from Shandong LD Grain & Oil Machinery Co,.Ltd has been widely- exported to more than 30 countries, like Russia, India, South Africa, Thai, Nepal, Indonesia and so on.
INSTRUCTIONS OF OUR REFINING TECHNOLOLD:
Basing on the traditional oil refining technoloLD, Shandong LD Co.,Ltd has developed the latest combined packing layer plate deodorization soft tower and the physical and chemical mixed refining technoloLD for crude oil of any quality.
Moreover, a series of advanced technoloLD and equipment are used, such as super wet deguming, bleaching earth automatic metering, negative pressure decoloring, high vacuum steam jet deodorization, deacidification, winterization dewaxing etc.
With advanced technoloLD, superior equipment, full-automatic control and excellent economic and technical parameters, our equipment can meet customers' different refinery requirements.

INTRODUCTIONS FOR THE MAIN PROCESSES:
Hydration Deguming & Alkali Refining Deacidification Process:
The crude oil is pumped out by the oil feed pump from the oil tank, then enters the crude oil
heat exchanger to recover part of heat after metering and after that it 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 change the non-hydratable phospholipids in oil into the hydratable phospholipids.
Add the alkali for neutralization, the alkali quantity and alkali solution concentration depend on the quality of the crude oil. The
neutralized oil is heated to the temperature (90Â°C) through the heater which is suitable for
centrifugal separation to remove the phospholipids, FFA and other impurities in the crude oil.
Then the oil goes to the washing process.
There is still about 500ppm soap in the neutralized oil from the separator. In order to remove
the remaining soap, add about 5~8% hot water into the oil, the water temperature should be 3~5 Â°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 90-95Â°C by the heater, and then enters the wash separator to separate the remaining soap and most
The water with soap and oil enters into oil separator to separate oil out from the water. Further catch the oil outside, and the waste water is discharged to the sewage
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 90Â°C should be sent to vacuum drier to remove the moisture, and then
the dehydrated oil goes to the ecoloring process. Finally, pump out the dry oil by canned pump.
Continuous Refining Decoloring Process:
The main function of decoloring process is to remove oil pigment, residual soap grain and
metal ions. The mechanical mixing method combined with steam mixing will improve the
decoloring effect under negative pressure .
The degummed oil enters into the heater firstly to be heated to the appropriate temperature
(110Â°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, and it 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 from contacting the air and influencing its peroxide value and color reversion.
Continuous Refining Deodorizing Process:
The qualified decolored oil enters into the spiral plate heat exchanger to recover most of the heat, then goes to high pressure steam heat exchanger to be heated to the process temperature (240-260Â°C) and enters the deodorization tower then.
The upper layer of combined deodorization tower is the packing structure which is mainly used
to remove the odor producing components such as free fatty acid (FFA); the bottom layer is the
plate tower which is mainly for achieving the hot decoloring effect and reducing the peroxide
value of the oil to zero.
Oil from the deodorization tower enters into the heat exchanger to recover most of the heat and
makes further heat exchange with crude oil, and then is cooled to 80-85Â°C through the cooler.
Add the required antioxidant and flavor agent, and then cool the oil below 50Â°C and store it.
Such volatiles as FFA from the deodorizing system are separated by the packing catcher, and
the separated liquid is FFA at low temperature (60-75Â°C). When the liquid level in the
temporary tank is too high, the oil will be sent to the FFA storage tank.
