摘要:

以鳀鱼预煮液为原料,采用陶瓷膜微滤的方法,研究陶瓷膜孔径及操作压力、温度、流速对过滤效果和膜通量的影响,得到最佳工艺条件:膜孔径为0.2μm、操作压力为0.25MPa、温度为40℃、流速为4.5m/s,在这个条件下微滤,可以减少陶瓷膜的浓差极化和降低膜的污染程度。

关键词: 鳀鱼蒸煮液, 陶瓷膜, 微滤, 膜通量

Abstract:

Engraulis japonicus soup was used as the material to explore optimal processing condition of ceramic micro-filtration membrane. Effects of membrane pore size, pressure, temperature and flow rate on filtration efficiency and membrane flux were investigated. The optimal filtration condition was 0.2 μm of membrane pore size, 0.25 MPa filtration pressure, 40 ℃ of filtration temperature, 4.5 m/s of flow rate. The polarization of concentration and contamination of micro-filtration membrane could significantly decrease under this optimal condition, which provided theoretical basis for industrialization of Engraulis japonicus soup through micro-filtration.

Key words: Engraulis japonicus soup, ceramic membrane, micro-filtration, membrane flux
