The process simulation model of deodorization of soybean oil was established by computer simulation technology. With deodorization pressure, deodorization feed temperature and dosage of stripping steam as operation variables, the experiments were performed using the process simulation model based on central composite design. According to the simulation results, the regression models for oil loss rate and retention rate of sito-sterol in deodorized oil were established with higher fitting degree and accuracy,which could provide reference for the application of computer simulation technology and mathematical modelling in the oil processing optimization. |
