Continuous soybean oil refining technology generally adopts oil centrifuge equipment. Its processing flow is as below:
Extracted crude soybean oil, filtration, mixing phosphoric acid, reaction mixture (water), centrifugation, heating, flashing off the solvent, cooling, second grade soybean oil
The main equipment selection is basing on characteristics of soybean oil refining process to determine. First, use self-cleaning centrifuge to ensure separation. Mixer turns mixing objects into hydrated phospholipids. Then add hot water, using a static mixer, phospholipids water sufficient to create conditions for centrifugation. Oil mixed in the reactor have enough time and space to fully react to form the desired structure flocculent oil feet, so that the centrifugal separation effect is obvious.
Advantages of continuous soybean oil refining technology and soybean oil refining plant :
The total oil refinery process is stable and only one time hydration can achieve second grade soybean oil. Continuous desolventization can also reach second grade soybean oil quality. This advanced edible oil refinery has superior advantages of short reaction time, fast separation technology, minimization of produced oil emulsification feet.
Soybean oil refining plant adopts mechanical centrifugation, which reduces oil feet content as low as 25%. It acquires high oil content and finishes whole processing line in sealed equipment. As a result, refined soybean oil has few chance to contact with air, thus it is always available in good oil color and good taste.
