In palm oil refinery plant, two kind of palm oil filtration machine are used. One is leaf filter machine for filtering waste white clay, another is membrane filter machine for separating the palm olein and palm stearin in palm oil fractionation process.
Leaf filter machine for filtering waste white clay
The selection of palm oil filtration machine will influence the quality of refined palm oil. Palm oil is naturally reddish in color because of a high beta-carotene content. The decolorization process consumes more white clay. Leaf filter machine can automatically finished the filtering work, and easily washing.
Membrane filter machine for separating the palm olein and palm stearin
And palm oil filtration machine is extremely important for improving yield of liquid palm oil during palm oil fractionation process. Currently industrial palm oil filtration machine contains drum filter, florentine-type continuous belt vacuum filter, and membrane filter machine.
The working principle of membrane filter machine
But in recent decades, membrane filter machine is widely used in palm oil fractionation plant, because it can fractionate high yield of soft fat as high as 70% to 75%, and palm oil stearin is available in bigger hardness. The other two types of palm oil filtration machines can separate lower yield of soft fat only 65%.
