Description of the process:
The crude palm oil has less hydratable & non-hydratable phospholipids and high FFA. So the line is adopted the physical refining method, which is not only much more economical and efficient than chemical refining, but also causes no pollution through waste water and exhaust air
Degumming process
Preheating the crude palm oil filtered for 45 degrees orso, then adds the phosphoric acid (less than 0.2%) and mixing for 15 mins orso in 90 degrees.
And use the hot water washing and settle for more than 2 hours ,in order to remove out the oil dregs/soaps.
Pre-Decolorizer process
Pump the oil deguumed into decolorizer vessel , samely open the vaccum system to rise its temperature to remove off the balance mositure , the temperature is 115 degrees ,to put into the mixture of crude oil and clay, mixing for 30 mins , then reduce the temperature to 70 degrees, and close the vacuum and filter the clay with oil filter, to get the oil decolorized .
Note: This process could remove out 40% red color,the more is removed out from the distilling process .
Distilling process
Pump the oil decolorized into the distilling vessel in the high vacuum, and 240 degrees –260degrees oil temperature, to distillate for 4hrs .
The FFA would be remove out with the direct steams.
The final oil is out after exchanging between hot oil distilled and oil decolorized.
Note: This process is not only remove out the FFA ,but also odor and most of red color / Hot sensitive decolorization.
Fractionation of oils and fats process
Dry fractionation of oils and fats is the separation of high-melting triglycerides from low-melting triglycerides by crystallization from the melt. Apart from blending, it is the cheapest process in oils and fats processing. It is a pure physical process compared to other chemical modification processes such as hydrogenation and interest-
erification which modify triglycerides. Dry fractionation is now applied to many kinds of fats: palm oil, anhydrous milk fat, tallow, fish oil, lard, cottonseed oil, sunflower seed oil, palm kernel oil, tallow butter fats, and special fats.
The most important applications are: palm olein used extensively as frying oil, palm super olein as salad oil and frying oil, the palm-mid fraction as component of cocoa butter equivalent, palm kernel stearin as cocoa butter substitute, anhydrous milk fat fractions for bakery and confectionery products, spreadable butter, tallow olein for frying oil and spreads. In this process, the fat is melted and heated to eliminate any crystal memory. The molten fat is cooled down under controlled agitation and cooling conditions to produce crystals nuclei formed by the higher melting triglycerides. Then, nuclei will grow to form crystals of the desired size. When the crystallisation has progressed far enough, the slurry is separated.
The final oil could be separated into 18 degrees,24degrees,33degrees according to melting degrees .
Transmit hot oil furnace
1. Introduce
The furnace is an organic carrier heating furnace with normal liquid oil for the medium; the fuel could be coal and diesel oil, waste oil. The hot temperature oil pump forcedly convey the hot oil recycle into the using system, realize to transmit the heats indirectly from the furnace to using system.
The important is that the furnace is not high pressure boiler, to reduce the inspecting cost every year.
Plate filter
Clear the oil decolorized and separate out the oil and waste clay .
Membrane filter
It separates the olein and stearin .
1. Die presses the reinforced polypropylene into filter plate, featuring smooth and flat surface, high intensity, light weight, acid and alkaline resistant, anticorrosion, nontoxic and inodorous.
2. The automatic hydraulic device is used for pressing and releasing the filter plate. The electrical contract pressure gauge is available to automatically maintain pressure.
Vacuum pump system
Steam jet vacuum pump system for decolorizing and distilling system.
1. Cooling water tower
With cooling system to supply for the cool water for the process.
