Cooking Oil Refinery for Peanut Oil

Pressure oil and extraction oil should all through chemical refining that can become edible oil. Only after pressing or extraction process that get crude oil, but can't be eaten. Pressure oil and extraction oil must through alkali refining and decoloring, deodorization, and other chemical process of refining to remove grease and impurities. Our company provides various kinds of oil refining, the following as peanut oil for example:

 

Vacuum Drying: There is still small quantity of water in oil coming from Washing Centrifuge. And the oil will affect the stability of oil, therefore pump the oil into the Vacuum Drier to remove the moisture in oil. Liquid level in the Vacuum Drier is controlled by floating ball. Pump out oil in the Vacuum Drier by Canned Pump.  


Deodorizing Section: Via Heater, Heat Exchanger, and Heater, the standard oil is heated to process temperature (240-260 ). Subsequently pump the oil to Combined Deodorizer. The Combined Deodorizer is combined type: the upper layers are packed type to remove odorizing components such as free fatty acid; the bottom layers are plate type to get effect of hot bleaching. Peroxide value in oil is reduced to almost zero. Oil from the Deodorizer enters into the condenser to recover most of the heat and makes further heat exchange. Finally the oil is cooled to 80-85℃ by Cooler. Volatile from the deodorizing system is separated by FFA Catcher. The separated liquid is FFA at 40-50.
