The grinding procedure resulting in particle size diminution (Figs. 3 and 4) brings about a gradual increase in glycerol conversion (Fig. 7) up to 88 and 92 % on H-SCH and H-SM modified samples. Glycerol conversion increased simultaneously with a diminution in particle size (Fig. 7). Therefore, one may conclude that the diminution of particle ...

From our experience, dry-grinding of cereals requires more effort than wet-grinding (Table 1). Only Job's tears were very easy to dry-grind into flour, which is consistent with the grinding experiment conducted by Liu et al. . In contrast, dry-grinding barley was difficult, an observation consistent with previous experiments (Lull et al. 2010 ...
