Super fine powderization of Korean ginseng using low temperature turbo mill

초록

It is investigated whether ginseng can be milled into super fine powder below 50 mu m, changing the circumferential velocity of impeller of a turbo mill(100, 110 and 120m/s). The mean particle size is 113.3 mu m in control but is decreased abruptly into 11.9 mu m at 120m/s. The largest particle diameter at 97% of volume distribution is reduced into below 32 mu m at 120m/s from below 725 mu m at control. The particle size distribution between d((0.1)) and d((0.9)) is 334 mu m at control, but is decreased into less than 26 mu m in all conditions after milling. It shows that ginseng can be milled into super fine powder by the turbo mill, which has the narrow particle size distribution.
