Abstract:
A vibration mill, called a “tandem-ring mill”, which has cog-ring media in place of the ball medium of a conventional vibration mill, was developed to achieve high-impact pulverization of lignocellulosic biomass. This study investigated a classification effect on enzymatic saccharification of tandem ring-mill pulverized lignocellulosic biomass as Japanese cedar. The Japanese cedar was pulverized by tandem ring mill for 35 min. The mean particle diameter of pulverized Japanese cedar was ranged from 30 to 40 micro meters. The powder density of pulverized Japanese cedar was ranged from0.50 to 0.66 g/mL. The enzymatic saccharification efficiency of holocellulose was ranged from 38% to 69%. The enzymatic saccharification efficiency was strongly related with powder density, regardless of particle diameters. To confirm the difference of saccharification efficiency, a classification of pulverized powder was carried out using several sieves. And classified powder was hydrolyzed by enzymatic saccharification. As a result, the enzymatic saccharification of classified powder was little change in classified levels for high enzymatic saccharification efficiency powder. Therefore, tandem ring mill pulverization gave powder uniform enzymatic saccharification reactivity regardless of the particle size.
