Product Description

Deacidification of palm oil refining machine :This part adopt alkali refining method, that is use alkalis (NaOH) to neutral the free fatty acid in oil, during this process it will produce soapstock, then separated from the oil by setting several hours. NAOH solution, not only neutral free fatty acid, also can act with other matters protein, mucus, phospholipid, pigment. After settling, release the soapstock from the tank bottom. Adding hot water to rinse, remove off the leftover lye, soap and some unhydrated phospholipid in the oil. Finally pumping out soapstock from the tank bottom.

Deodorization and Dehydration of palm oil refining machine :Usually ,there are some odors in the crude oil, it affects the quality of the edible oil . About our refining process, we usually use the direct steam to take odors away in the vacuum condition . General speaking there is about 0.5% water in the alkali refined oil, in the deodorization pot, thetemperature is very high, it also can finish the dehydration section.

Flow chat of palm crude oil refining

Brief introduction of palm crude oil refining

1. Acid reaction process

Oil temperature can be adjusted by screw plate heat exchanger. When the temperature is heated to about 80℃, mixing about 85% food grade phosphoric acid into acid reaction tank for reacting. 2. Neutralization process

In neutralization section, adding alkali liquor with appropriate concentration into the degummed oil which have proper temperature, then degummed oil enters into the centrifugal mixer for mixing.

3. Washing process

Neutralized oil come from neutralization separator, still contains about 500 ppm soap. During the washing, hot water will absorb the soap and other impurities in oil, then soap and impurities are separated in washing separator.

4. Vacuum drying section

The neutralization and washing oil come from the washing separator still contains some water which is adverse to the oil stability.

5. Bleaching process

The main purpose of this process is to remove the pigments in crude oil and the residual soap in the neutralization oil.

6. Filteration

Miscella mixed by oil and clay from bleaching tower is pumped into decolorizing filter, then enters into fine filter, in which clay and fixed impurities are blocked.

7. Deodorization process

Deodorization process aiLD to remove the FFA and low molecular compounds in bleached oil. Entering into the deodorization process, the flow of bleached oil is controlled by a flow controller, and the oil is heated to250-260℃ through a series of heat exchanger, then the temperature can reach to the condition of deodorizing.

8. Dewaxing process

Bleached sunflowerseed oil enter into crystallizing tank through heat exchanger and begin the cooling crystallization proces,this process is controlled by the computer through the parameters preestablished,the computer controls temperature of circulating water in the frozen coil to comand cooling speed of the oil,thereby receive thecrystal result.
