The degumming system is designed to degum crude vegetable oil. The Degumming System will generally produce oil with lower levels of residual phosphatides and less residual pigments and therefore require less bleaching earth in bleaching as well as help generate finished deodorized oil with a lighter color and longer shelf life. The Degumming System is illustrated on the attached drawing.

The oil is delivered to the Degumming System by the Feed Pump. It is heated to 65 - 70 C in the Crude Oil Heater by steam in the Feed Heater and then mixed with acid solution in the Mixer. The mixture is delivered to reaction vessel with agitator for completion of reaction. The mixture from reaction vessel is cool down to 25-30 Deg C and mixed with desired quantity of water. This mixture is delivered to hydration vessel with agitator for coagulation of phosphatides..

The coagulate mass is transferred to centrifugal separator through heater to heat the oil 70-80 Deg C. for separation of gums from oil. Separated gums are collected in gum tank and delivered to storage or to desolventizer toaster. Degummed oil from separator is transferred via heat exchanger to vacuum drier for removal of moisture from oil. Dried oil from drier is delivered to dried oil storage tank.
