What is vegetable oil refining?
Crude oil Extracted from press expellers or solvent extraction plant inevitably contains impurities. To make the edible oil , the impurities must be taken out; such a process is
called "Refining" Oil refinery refers to a series of refining processes that can remove FFA, gums, waxes, phospholipids and free fatty acid (F. F.A.), pigment, off-flavor and
other impurities in the oil. Vegetableoil refining machine is necessary for vegetable oils & fats or animal oils & fats so they can be used for cooking and frying foods.
Main Equipments in Small vegetable oil refining line:
Heat Conduction Furnace: 1 set Offer enough thermo for the refining sections.
Steam Generator: 1 set Produce steam for the workshop
Refining Pot: 2 sets Remove the gum, phosphoric acid etc,
Decolorizing Pot: 1 set Remove the color from neutralized oil
Deodorizing Pot: 1 set Remove the solvent, smell, water from decolorized oil
Other Auxiliary Equipments: Hot water Tank, Bleaching earth Tank, Air compressor, pumps, filters, Valves, Electricity Control Cabinet, etc.
What are the features of vegetable oil refining machine?
1.Wide application for oil bearing seeds.
2.Change different oils easily.
3.Less investment but with full refining function.
4.Easy to install and operate.
5.Light weight and movable.
What is the process of vegetable oil refining machine?
Degumming: Remove gums in the crude oil to improve oil edibility, storage and do well to downstream neutralizing section.
Neutralizing: Remove Free-Fatty Acids (FFAs) with caustic soda (NaOH). Soap stock is generate in this process.
Decolorizing /Bleaching: Remove color pigments contained in oils.
Deodorizing: Remove disagreeable flavor and odors that are naturally present or created during processing under high temperature.
Dewaxing (Optional): Oils like sunflower oil or maize germ oil (corn oil) have waxes present in them. At low temperatures these waxes give a hazy appearance to the oil. So in
extremely cold areas, dewaxing is necessary when processing these oil seeds.
