Different typs of edible oil refinery plant

Edible oil refinery plant introduction:oil refining is a way to get rid of the harmful impurities and needless substance in the crude oil, aims at improving the oil storage stability,flavor and color.then get standard edible oil or provides qualified material for deep processing.

From crude edible oil to standard edible oil equipment
Edible oil refinery plant workflow
Crude  oil →Degumming → Deacidification  → Decolorization →Deodorization → (Winterization/Fractionation) → Standard edible oil

Function of each process in edible oil refinery plant:
Degumming of edible oil refinery plant :Adding water and little P-acid to combined with the impurities and then remove the gum.
Deacidification of edible oil refinery plant :Using alkali like (NaOH) to neutralize FFA in oil, during this process it will
Get nigre, then separating it from the oil.
Decolorization of edible oil refinery plant :using the active clay to absorb the pigment in oil, then separating the waste clay. You will get light yellow color oil.
Deodorization of edible oil refinery plant :the crude oil smells not good, it will affect of oil storage and price. So we usually use the direct steam to take away odors. At the meanwhile, it can also remove water and FFA from oil.
winterization/fractionation of edible oil refinery plant :Oil is consist of triacylglycerol with different melting point.under a  specified temperature,there will has some solid part come out from oil,it will affect the appearance and price.winterization and fractionation is to remove or separate the solid part to get fully liquid edible oil.it is suitable for some kinds of vegetable oil,like rice bran oil,sunflower oil,corn germ oil,palm oil etc.
Different typs of edible oil refinery plant:
Mainly there are two methods of refining:chemical method and physical method.different demand we can devide the edible oil refinery plant into three types:batch type,semi-continuous type,fully-continuous type.          
Batch type edible oil refinery plant:the process is to refine the oil batch by batch,suitable for small capacity like 1-2-3-5-10TPD.

Semi-continuous type edible oil refinery plant:part of the refinery plant is batch type and left part is continuous type.this is cost-effective and save labor.suitable for medium capacity like 10-30TPD
semi continuous type refinery plant
Batch type edible oil refinery plant

Continuous type edible oil refinery plant:the whole refinery process is fully continuous,no need much human operating.suitable for big capacity above 30TPD
continuous type refinery plant
