Palm oil mill plant
Palm oil mill plant is used to extract crude palm oil from palm fruit and get high oil yield palm oil. Palm oil mill plant, also called as palm oil extraction machine, are utilized in palm oil mill or palm oil pressing plant for effective palm oi production. The design and technology of palm oil mill plant are very important for its smooth operation and further maintenance.
Next we will introduce the palm oil mill plant from palm fruit to palm oil:
Next we will introduce the palm oil mill plant from palm fruit to palm oil:
Palm fruit oil
Oil palm begins to bear fruits about two years and a half after being transplanted. Firstly, the output is very low, 8～15years is blooming time and output reach maximum; it gradually aging when it grows over 20 years; its growth period is 25～30years. Per-hectare land should plant about 140-palm tree in general, annual output is about 20T fresh fruit bunches; after being processed, about percentage 20 is crude palm oil and percentage 20 is kernel.
And for the palm oil extraction machine, we can do different capacites:
Small capacity: 1tph, 2tph, 3tph, 5tph.
Large capacity: 10t/h,15t/h, 30t/h 60t/h, to 120tph.

Palm oil extraction process
Raw materials storage section in the palm oil mill plant: Collecting the ripe fresh cluster from the orchard and convey by trucks, then pour the fluster into the discharge door after weighed by ground weigh bridge.
The discharge door has discharging channels, the upper and lower switches of the iron gate are controlled by pneumatic, Pneumatic control system consists of air compressor and pneumatic control devices. Start the control valve to open the gate of the discharge door, then the palm fruits will fall into the fruit basket car or conveyor.

Palm fruit threshing machine
The crasher also has the steam heater. The purpose of crasher is to separate the pulp and nut and crush the palm pulp. At the same time, the steam is used to cook the palm fruit and broke the cell of pulp. The best condition of cooking is 90～100℃ for 20 min. The tubes of the crasher use the indirect steam to heat the crasher and palm fruit. The direct steam is added to the inner of crasher. The direct steam is used to adjust the water content and temperature in the crasher. The central shaft includes lots of blade to crush the palm fruit. The palm fruit is entered the crasher from the top and discharged from the bottom.
Palm fruit digesting machine
Before pressed, oil palm fruit first be carried out cooking, sterilized fruit must be re-heated to make the pulp soft and damage pulp cell structure.
After sterilized, threshing and crasher, the palm pulp become soft and cell is broken. Then it is sent to continuous screw press. After pressing, oil palm fruit is divided into two parts: the mixture of oil, water and solid impurities, and the press cake (fiber and nut). The mixture of oil, water and solid impurities inflows to oil purification section by the crude oil gutter. The pressed cake is sent to the fiber- recovery section by breaking screw conveyor.
Palm fruit pressing machine
Machine-pressed crude oil first diluted with water washing, through settlement and filtration, the fiber material removed from the oil, and then carry out continuous settlement, the whole divided into two parts: oil and sediment. Oil by centrifugal separation and through vacuum drying pumped into the storage tank for storing; oil sediment by filtration and dirt oil separation, oil process second settlement, dirt oil mixture process clarification separation, Skim oil then carry out a second settlement, sewage pumps to sewage treatment pond for dealing with.
Palm oil clarification machine
Press cake broken by breaking screw conveyor and then transported into the fiber separation air net and fiber polishing roller for fiber separating. The separated fiber material is sent to the boiler room as fuel; the separated stone is transported to stone warehouse by pneumatic conveying system for temporary storage.
