edible oil refinery plant
The Technology Introduction
1). Degumming Section
The solid impurities in crude sunflower oil will be removed by bag filter, and measured
accurately by mass flowmeter, and then enter the degumming workshop to remove
the colloidal, the crude palm oil heated will be exchanged the heated, it will be fully
mixed with phosphoric acid, the mixture will react in the acid tank. After the reaction,
the alkali liquid will be added in, the partial neutralization reaction will be done here,
and then the colloidal, starch and other impurities contains in oil will be separated out.
This is preparation for oil press machine and cold press oil machine.
All temperature in the whole degumming process is automatic control and adjustable,
and all operations can completely achieve in control room.
2). Decoloring Section
The decoloring section adopt 50 tons/day device. The degummed oil will be pre-heated
by the deodorization refined oil, then it will be heated and enter pre-mixing tank.
Meanwhile, the clay which is measured by metering device directly in clay tank,
and then the measured clay will be added to the pre-mixing tank. After a fully mixing,
the mixture of clay and oil will be sent into the decoloring tower,
the color will be removed here.
The decolorization reaction in decoloring tower will last about 30-60 minutes.
Then the mixture will be pumped out and filtered by Armagh filter, the waste clay
will be separated from the oil. The residue clay particle will be firstly filtered
by the precision filter and then go into the gassing evolution tank to remove
the moisture and volatile matter. The whole decolorization process temperature is
self-control and adjustable. The filtration system has achieved the feeding
oil automatically, circulation, filtration, baked cakes, slag and other
operations by manual implementation.This is preparation for oil press machine
and cold press oil machine.
3). Deodorization Section
Gas substances from the decolored oil from the decolorization section will
enter the deodorization section to remove the free fatty acids and unpleasant gas.
All of this of oil press machine will be removed under the high vacuum circumsatnces
by the deodorization tower. Using the to remove these substances by steam under high
vacuum conditions. The removed fatty acid will be collected by the fatty acid trap and
pumped into the receiving tank, this later will be used as vice products,
it's good for cold press oil machine.
4). Winterization Dewaxing Section
The deodorization oil gets into the crystallizing tank, the cooler will adjust the
temperature to 50℃, then in crystallizing tank the cooling water will cool the oil to 20℃,
after 72 hours crystallization, filter the oil to remove the wax.
