Product Details

Palm oil processing machine China manufacturer with CE ISO certificated

Palm oil pressing batch system loads boiled palm fruit and output crude palm oil to clarification equipment.
Vertical digester with a perforated bottom plate pound batch of palm fruit, and then flush out the oil and other non-oil solids from the pounded pulp with hot water. Palm oil screw press is designed to pound batch of boiled palm fruit at beginning while inflicting pressure on pounded pulp in another section to get palm oil.

The advantage of palm oil pressing batch system is that it completely leaches all oil and non-oily solids with simple operation, which can be carried by fluid stream out of the digested mash to give clean and separated nuts and fibre. The aqueous effluent from vertical digester goes directly to the clarification stage. The amount of water needed to flush the pulp normally equals to the amount to dilut the viscous oil coming from the mechanical press in preparation for clarification. An inexperienced operator may use too much hot water to leach oil and thus cost unnecessary wood as fuel.

The oil yeild of palm oil pressing batch system is severely reduced when flushing water is cold. In digesting, water and oil will form an oil/water emulsion that is difficult to separate from fibre mass. Emulsified oil loss with the fibre would be substantial without care to ensure full loading of the digester. Vertical flushing digesters, requiring loading and discharging of a specific amount, can thus only be used in palm oil pressing batch system.

The purpose of palm oil refining :
Palm oil refining process refers to a series of refining processes that can remove phospholipids, FFA, pigment, off-flavor and other impurities in the palm oil. Palm oil refining process or vegetable oil refinery is essential to ensure removal of gums, waxes, phosphatides and free fatty acid (F. F.A.) from the edible oil. To impart uniform color by removal of coloring pigments and to get rid of unpleasant smell from the palm oil by removal of odiferous matter.

Palm oil refining process:
Palm oil refining usually includes the following sections: degumming and deacidification, decolorization, deodorization and fractionation. Palm oil refining method is according to different usages and requirements , utilizing the physical methods and chemical processes to get rid of the harmful impurities and needless substance in the crude palm oil , getting some standard oil .

Refining methods for palm oil refining:
There are two refining methods for the palm oil refining in the palm oil refinery plant. They are physical refining and chemical refining. Physical refining means removing gum in palm oil during process of degumming in special method and removing FFA in process of deodorizing by steam. Chemical refining, however, means removing FFA in a chemical way ( Acid-base neutralization). Gum and soap foot produced is separated by centrifuges.
Palm oil refining - Chemical Refining
1.The finished oil is consistent and stable.
2.Excellent adaptability and less requirement to oil quality.
3.Less bleaching earth is added into compared with physical refining.
Palm oil refining - Physical Refining
1.High oil refining rate, less oil loss.
2.No waste water discharged.
3.Especially suitable for oils of high acid value, and low gum content.
4.More FFA distilled out.
