Abstract
In order to improve the traditional methods of procyanidins extracting, ultrasonic-assisted filtration was used in the process of extracting proan-thocyanidin which was from membrane concentration of grape seed. Through the mechanism analysis of ultrasonic-assisted ultrafiltration, ultrasonic is able to alleviate the phenomenon of concentration polari-zation, so the efficiency of extracting proanthocyanidins was improved. Based on the phenomenon that ultrasonic enhanced membrane concentration of procyanidins extracting, BP neural network was used to construct the ultrasonic-assisted filtration membrane-flux model, and the genetic algorithm was used to optimize the parameters of ultrasonic-assisted filtration. The research results show that the optimal process parameters of ultrasonic-assisted are ultrasonic power 240W, number of vibrator 6, angle of vibrator 40°and ultrasonic time 9 min. Itrafiltration flux increased by 42% under the above conditions.
