2TPD, 5TPD ,10TPD Palm oil / Soybean oil refining machineRefining Technology Description
Degumming Section
The solid impurities in crude palm oil will be removed by bag filter, and measured accurately by mass flowmeter, and then enter the degumming section to remove the colloidal, the crude palm oil is heated through heat exchanging and heating, it will be fully mixed with phosphoric acid, and start reaction in the acid tank. Then add lye to start partial neutralization reaction, and then the colloidal, starch and other impurities in oil will be separated out .
All temperature in the whole degumming process is automatic control and adjustable, and all operations can completely achieve in control room.
Bleaching Section
The degumming 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 bleaching tower, the color will be removed here. The bleaching reaction in bleaching tower will last about 30-60 minutes. Then the mixture will be pumped out and filtered by 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 bleaching process temperature is automatic control and adjustable. The filtration system has achieved the feeding oil automatically, circulation, filtration, blowing cakes, discharging slag and other operations by manual implementation .
The bleaching section design trapping odor device, the odor in the steam will be purged by the circulating water, thus to eliminate odor pollution in bleaching.
Deodorization Section
Gas substances from the bleaching oil from the bleaching section will enter the deodorization section to remove the free fatty acids and unpleasant gas. All of this will be removed under the high vacuum circumstances 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.
In order to save energy, the bleaching oil will firstly heat ex-changed with the deodorization oil by heat exchanger, and then heated to the deodorization temperature of about 235ºC with organic heat carrier.
The water circulating vacuum pump was adopted in vacuum system in the deodorization section , the extracted odor in deodorizing vacuum will be trapped by the circulating water, thus eliminate the off-flavor in deodorization section.
