Palm oil is an edible vegetable oil derived from the mesocarp (reddish pulp) of the fruit of the oil palms. Palm oil is naturally reddish in color because of a high beta-carotene content. It is not to be confused with palm kernel oil derived from the kernel of the same fruit....
The differences are in color (raw palm kernel oil lacks carotenoids and is not red). However, crude red palm oil that has been refined, bleached and deodorized, a common commodity called RBD palm oil, does not contain carotenoids.
Palm oil is a common cooking ingredient in the tropical belt of Africa, Southeast Asia and parts of Brazil. Its use in the commercial food industry in other parts of the world is widespread because of its lower cost.
The palm oil is the world's second largest edible vegetable oil, only ranking after soybean oil. At present, Malaysia and Indonesia is two largest palm oil producing countries in the world. Besides, there are many palm oil processing plants in Africa, such as Nigeria, Ethiopia, Congo, Ivory Coast etc.
Our company is professional in manufacturing palm oil plant for years. At present, we research and design a new technology of palm oil milling machine, based on our rich experience in palm oil plant.
Process Flow of Palm Oil Plant
FFB means fresh palm fruit bunch. Palm oil fruit can be harvested all the year round. After cutting from palm trees, fresh palm fruit bunch must be processed within 2days. Or the acid value will be high and affect the final palm oil quality.
Fresh palm fruit bunch
BUNCH STERILIZATION: FFB (fresh fruit bunch) have to be sent to sterilize to avoid AV (acid value) rise by sterilize the fatty enzyme with high temperature. At the mean time, sterilizing section can also soften the fruits, which benefits the threshing section and reduces the damage to kernel.
BUNCH THRESHING: The purpose of threshing is to separate the palm fruit from the FFB by rotary drum thresher.
FRUIT DIGESTION: The purpose of digestion is to separate the pulp and kernel, soften the pulp with heat and to destroy the pulp cell structure.
PULP PRESSING: After sterilizing, threshing and crashing, palm pulp become soft and the cell structure is broken. In another word, we can easily get the oil with spiral oil press, which is also called CPO(crude palm oil).
