There are three basic processes in vegetable oil refinery. The first process is to eliminate free fatty acids (FFA). Neutralization reaction occurs in the neutralizer by adding caustic soda. The oil is heated to about 60 degrees celsius by hot fluid and stirred by a stirrer. Then the soap stock formed by chemical reaction settles at the bottom of the neutralizer and is removed to the soap tray.

Henan Huatai Oil Machinery is engaged in the production of various vegetable oil refinery, including sunflower oil refinery, rice bran oil refinery, palm oil refinery, peanut oil refinery, soybean oil refinery and other vegetable oil refinery.

The neutralized oil enters the second reactor, which is the decolorizer. The color of the oil is eliminated by bleaching with chemicals such as carbon black and bleaching agents. The temperature of the oil should be 110 degrees celsius, while stirring. The bleaching process occurs under vacuum conditions.

The decolorized oil is filtered by a filter press, and then the white clay and chemicals are separated. Then the decolorized oil after filtering goes into the deodorizing pot, the oil temperature is over 110 degrees celsius, by providing steam from the bottom, the temperature goes from 200 degrees to 220 degrees through the hot fluid coil. The whole process takes place in high vacuum, and the taste is removed under high vacuum conditions. Then it goes to the condenser, the heat is taken away by water circulation and the oil is cooled. Then it goes to the second filter press to get the fully refined oil with good color and transparency. In the vegetable oil refinery, the hot fluid boiler, vacuum pump, barometric condenser, and steam generator have their own specific functions. These equipment are connected to the reaction tank through pipelines as part of the vegetable oil refinery.
