20 TPD Crude Palm Kernel Oil Refining Machine/Crude Palm Oil Refining Machine Technology Introduction

1. Crude Palm Oil Refinery Section:

A. 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 workshop to remove the colloidal, the crude palm oil heated will be ex-changed 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 partia

neutralization reaction will be done here, and then the colloidal, starch and other impurities

contains 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.

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 the 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 .

The decoloring section design trapping odor device, the odor in the steam will be purged by the circulating water, thus to eliminate odor pollution in decolorization.

3. Deodorization Section:

Gas substances from The dcolored oil from the decolorization section will enter the

deodorization section to remove the free fatty acids and unpleasant gas. All of this will be

removed under the high palm oil refining equipment circumsatnces by the deodorization tower. Using the these substances by steam under high palm oil refining equipment 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 decolored oil will firstly heat exchanged with the deodorization oil

by heat ex-changer, and then heated to the deodorization temperature of about 235-236℃ by high pressure steam.

The water ring palm oil refining equipment pump was adopted in the deodorization section palm oil refining equipment system, the

extracted odor in deodorizing palm oil refining equipment will be trapped by the circulating water, thus to eliminate

the odor pollution in deodorizing section.

2. Palm Oil Fractionation Section:

Fractionation Theory: The natural oil is consitute of mixed triacylglycerol mixture. Due to the

difference of the triacylglycerol fatty acid carbon chain length, unsaturation, the constitute and

the plate of double bond and each fatty acid distribution in triacylglycerol is different, all of

these make the difference in physical and chemical properties. The fractionation is based on the melting point and solubility difference, separate the oil into solid and liquid two parts under a

certain temperature. Though the operation and theory of fractionation and winterization is

similar, but the purpose of the two methods is different.

The technology: The palm oil will be heated clear and transparent and by the heat ex-changer and then send into the C1001-C1006 crystallization tank, the crystallize program will begin after starting the stirring and PU1001-PU1006 cooling water circulation pump; When the water cooling quantity in the the C1001-C1006 crystallization tank is insufficient, opening the freezing water to process crystallization; The freezing procedure design depends on the crude oil, esters and oil ratio. During the crystallization period, cooling the oil to the filtration temperature according to a predetermined cooling curve, thus to guaranteed to produce a good

crystal. In crystallization process, the computer will calculate the cooling gradient automatically, the temperature of the oil and water will be measured and recorded, the water temperature will

be controlled by the microprocessor program, so that can realize different stages need different water temperature, to ensure that the whole crystal growing period of the cooling curve

smoothing, the crystallization can be carried out in the most suitable conditions, but not in a

large number of crystal exothermic crystallization to destruction, to ensure the smoothness of thecooling curve in crystallization process. This can make the crystallization progressing under the

optimum conditions and the crystals won't be damaged by the heat emission of the bulk

crystallization. This ensures the stable crystals' formation which is benefit for the next step filteration and the precise cooling way ensures the maximum adaptability and day treatment batch

number.

When the crystallization reaches to the C1001-C1006 crystallization tank required temperature, it will conveyed by the PU2001 pump to F2001 filter, when the F2001 forms a filteration cake

layer and the refined oil is clear and has no particles appears, the F2001 refined oil will go into

the V2001; when the F2001 is fully filled, the filter will enable the extrusion, baked cakes, slag

and other operations, so as separate the oil and wax fully. For the the first filter in winter time,

the filteration will be halfway, some particles will get through, but it will be filtered fully by the

filter paper of the second filter so that make the refined oil is qualified; When the C1001-C1006 crystallization tank finished the filtration, the palmitic, stearic will melt and storage to the irrigation area.
