淀粉分离用超重力微旋流装置分离性能研究

设计了一种新型超重力微旋流装置。采用单因素和双因素试验方法,研究进料流量、底流分率、进料浓度和溢流口直径对大米淀粉和马铃薯淀粉分离性能的影响。结果表明:在单因素试验中,进料流量、底流分率和进料浓度对淀粉的分离总效率的影响较明显;在双因素试验中,进料浓度、溢流口直径和底流分率对大米淀粉分离总效率的主效应极显著;进料浓度和底流分率的交互效应极显著,溢流口直径和底流分率的交互效应极显著。

Study on separation performance of an ultra-high-gravity mini-hydrocyclone for starch production

A novel ultra-high-gravity mini-hydrocyclone was designed. One-factor experiments and two-factor experiments were conducted to study the effects of the feed flow rate, split ratio, feed concentration and vortex finder diameter on separation performance of rice starch and potato starch, respectively. The results indicated that the effects of the feed flow rate, split ratio and feed concentration on the total separation efficiency for rice and potato starch were remarkable in the one-factor experiments; the feed flow rate, split ratio and vortex finder diameter significantly affected the total separation efficiency in the two-factor experiments. The interaction effects between the feed flow rate and split ratio significantly affected on the total separation efficiency, and the interaction effect between the feed flow rate and split ratio had a high significance to the total separation efficiency.
