Palm oil processing in Nigeria

Palm oil processing description :

Palm fruit bunches

The oil winning process, in summary, involves the reception of fresh fruit bunches from the plantations, sterilizing and threshing of the bunches to free the palm fruit, mashing the fruit and pressing out the crude palm oil. The crude oil is further treated to purify and dry it for storage and export.

Large-scale plants, featuring all stages required to produce palm oil to international standards, are generally handling from 30 to 120tonnes of FFB/hr. The large installations have reception station,sterilization station, threshing station,digesting & pressing station and crude palm oil clarification station. Most processing operations are automatically controlled and routine sampling and analysis by process control laboratories ensure smooth, efficient operation.

Conversion of crude palm oil to refined oil involves removal of the products of hydrolysis and oxidation, colour and flavour. After refining, the oil may be separated (fractionated) into liquid and solid phases by thermo-mechanical means (controlled cooling, crystallization, and filtering), and the liquid fraction (olein) is used extensively as a liquid cooking oil in tropical climates, competing successfully with the more expensive groundnut, corn, and sunflower oils.

Extraction of oil from the palm kernels is generally separate from palm oil extraction, and will often be carried out in mills that process other oilseeds (such as groundnuts, rapeseed, cottonseed, soybean or copra). The stages in this process comprise cleaning machine ,crushing machine,softening machine,flaking machine ,cooking machine,pressing machine and extracting the oil using an oilseed expeller or petroleum-derived solvent. The oil then requires clarification in a filter press or by sedimentation. Extraction is a well-established industry, with large numbers of international manufacturers able to offer equipment that can process from 30-2000tpd.

Alongside the development of these large-scale fully mechanised oil palm mills and their installation in plantations supplying the international edible oil refining industry, small-scale village and artisanal processing has continued in Africa. For this, Henan Doing Mechanical Equipment Co.,Ltd developed and produced small scale palm oil processing machine with 1tph,2tph,3tph......10tph and single palm oil machine.

All palm oil equipments produced by Henan Doing Mechanical Equipment Co.,Ltd can realize mechanized operation.Next is the pictures of palm oil processing machine .
