Palm Oil Filtration selection is extremely important for improving yield of liquid palm oil during palm oil fractionation process. Currently industrial filtration system contains drum filter, Florentine-type continuous belt vacuum filter, and thin film filter.

In recent decades, thin film filter has been widely used in palm oil fractionation since it can fractionate high yield of soft fat as high as 70% to 75%, and palm oil stearic is available in bigger hardness. The other two types of filters can separate lower yield of soft fat only 65%.
