Palm oil is an edible vegetable oil derived from the fruit of the oil palms, palm oil and palm kernel oil are produced from pulp and kernel respectively, which are widely used in catering industry, food industry, etc. Why do food manufacturers prefer to use palm oil?
Palm oil is a kind of plant oil made from tropical woody plant-Palm. It is one of the largest produced, consumed and traded oils in the world, which is called The World’s Three Major Vegetable Oils together with soybean oil and rapeseed oil.
Palm oil after pressing, refining and fractionation can get different melting point products, which are widely used in catering industry, food industry and oil & fat industry.
It is used for removing the iron impurities, stone, fiber and others. These impurities are bad for machines, especial for the palm kernel oil expeller.
Because the palm kernel is hard and big size, it is required to crush to smaller and even pieces. If once crushing can not reach the requirements, the second crushing is required. Crush palm kernels after softening and drying. The centrifugal crusher breaks nuts and separate palm kernel out completely.
Palm Kernel and Nuts Shell Separation
Both dry and wet separations are available. Wet separation is mostly used in palm kernel separation, on basis of difference of relative density of palm kernel and shell.
Fresh kernel contains 20% moisture. Palm kernel has no mildew during transportation and storage while moisture drops below 7%.
It is used for heating and cooking the crushing materials, to make is suitable for pressing, doing like this can help final user get the maximum oil and good quality cakes.
Palm kernel oil pressing processing line is simple with usual oilseeds. The pre-pressing by oil pressing machine can obtain 1/4 palm kernel oil, and residual oil need twice pressing.
After pressing, there are some oil dregs in the crude oil, after clarifying, we need to filter the crude oil to avoid to jam the oil pipes during refining processes.
Oil pressed from pre-press and solvent extrating are both crude oil. For using in cooking, crude oil should be refined for edible oil for human being. Refiney section is mainly the parts for Degumming and Neutralizing, Bleaching, De-waxing, and De-odorizing. Then refined oil can be used directly for daily usage.
After previous pre-treatment and pressing, crude palm oil shall be refined in complete oil refining line to get rid of FFA, natural pigment (decoloration) and odor (deodorization), and become salad leve oil – refined palm olein (RBD PO) and palm salad oil (RBD PKO).
The palm oil after refining is nearly colorless and transparent under liquid state, and is white under solid state. Besides, according to different user requirements, palm oil can further go through fractionation process to form PFAD, Olean, and Stearine.
Refined oil fractionation: after entering the fractionation tank for cooling, the upper layer liquid is 24℃ OLEIN (i.e. 24℃ refined oil), the lowest layer is 44℃ solid refined oil, the output ratio is 24℃: 75%, 44℃: 25% (the highest cost). B. Pressure filtration: equipment is constant temperature plate pressure filter; if user want to production 24℃ oil, the temperature is set at 24℃, add pressure 6 – 10 atmospheres, liquid oil flow out, and solid fats discharged from the plate.
