⭐Plam Fruit Harvesting: The initial process in palm oil mill is reaping the palm fruit bunches.
⭐Palm Fruit Sterilizing: Through fruit reception system, the palm fruit bunches will be transported to the next process - Sterilizing Station. The disinfection process utilizes steam or water to sterilize the fresh palm fruits. This process likewise stops enzymatic responses that prompt oxidation and upsets the cells which are found in the mesocarp, so that to improve the oil extraction efficiency and final oil product quality. Dry sterilizing means roasting or smoking the fruits, while wet process means boiling or steaming the fruits. If choose dry process, the palm fruits are separated first, and then sterilized. If use wet process, the fruits are sterilized before threshing.
⭐Palm Threshing: In the threshing process of palm oil mill. The fruitlets are separated from the whole bunches by use of stripper machine. Threshing is generally mechanical in large palm oil mill by use of thresher, which rotates or vibrates to remove the fruits from the bunch. Pam fruits will be conveyed to palm oil presser to get CPO. Palm bunch can be used as fertilizer or fuel.
⭐Digesting: Before extracting oil, the palm fruits need to be crushed in digester machines. To augment oil yield, the fruit pulp is also warmed in this process. The mesocarp and nuts can be squeezed together in palm oil making/pressing machine. But if you plan to make Grade A Palm Oil, the palm nut/kernel should be removed before oil pressing section.
⭐Oil Pressing: The pulp is then pressed, which bursts the oil-containing cells, releasing the palm oil. There are several types of oil making machines that may be used to press the fruit pulp, including manual presses, hydraulic presses, and screw presses. The screw press is the most commonly used palm oil making machine in both small and large scale palm oil manufacturing plant due to its high oil extraction rate.
⭐Palm Oil Clarification: The purpose of clarification in palm oil manufacturing process is to remove impurities. The final crude palm oil will be storage in bulk in a tank.
⭐Palm Kernel Recovery: After palm oil expelling, the solids parts discharged from the screw press is mixture of fiber and nuts. In palm kernel recovery plant, the nuts and fiber are separated by physical means. The nuts are sent to palm kernel crushing and solvent extraction plant to make palm kernel oil, while the fiber is used as biomass fuel in boiler on-site.
We will choose the palm oil mill process according to the different requirements of different customers. Both technical and economic effects are taken into account while plan the palm oil mill process, so that to build the best palm oil mill plant.
