Large scale industrial palm oil milling machinery for sale

The above video shows the overall structure and main equipment of a large scale Industrial(commercial) palm oil mill plant. In general, the palm oil milling machinery used in large scale palm oil mill plant in Southeast Asia, are all like this video shown.

Large scale palm oil mill plant is usually built near the palm oil plantation. Because of high lipase content, long time storage will make the palm fruit acid, which will influence the quality of crude palm oil.

The complete large scale palm oil milling machinery includes a series of different sections, such as Fresh palm fruit bunches reciption section, Sterilization section, Threshing Section, Digesting & Pressing section, Oil clarification section, Palm kernel recovery section and so on.

The working process of large scale palm oil milling machinery:

The main equipment in each section:

Fresh Palm Fruit Bunches Reception & Storage Section:

Palm fruit reception section

Collecting the ripe fresh palm fruit bunches from the plantation and transported by trucks to palm oil mill plant. Then pour the FFB into the discharge door after weighed by weighbridge.

It is the beginning part of the large scale palm oil milling machinery running. The discharge door has discharging channels. 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 Sterilization Section:

Palm fruit sterilizing machine

Sterilization is a process, to inject steam directly into to sterilizer, then boil the palm fruit for about 60 mins. The purpose of sterilization is to break the enzymes in palm fruits and avoid the increasing of the FFA content in palm oil. Meanwhile, the high temperature will make the fruits soften, which will make it easy for palm fruit threshing and palm kernel cracking section.

Palm Fruit Bunches Threshing Section:

Palm fruit threshing machine

The purpose of threshing is to separate the palm fruit from the FFB. The drum type thresher is the common used in large scale palm oil milling machinery. The separated palm fruits are sent to the digesting & pressing section. Empty palm fruit bunches are transported to boiler room as fuel or to other place to further process.

Digesting & Pressing Section:

Palm oil pressing machine

Digesting is for breaking off the palm fruit, and with high temperature to soften the fruit and kills the bacteria. The large scale palm oil milling machinery use double screw palm oil expeller, which is with hydraulic control system to adjust spacing between screws. So it is suitable for various palm fruit species and guarantee the oil yield.

After pressing, the palm kernel and fiber mixtures are sent to palm kernel recovery section and the crude palm oil is sent to the palm oil clarification section.

Crude Palm Oil Clarification Section:

After pressing, the palm kernel and fiber mixture can be processed by further separation. After drying, the palm kernels are stored for deep processing, and the separated fiber and shells are used as the boiler fuel for providing steam.
