Effects of corn kernel hardness and grain drying temperature …
In addition, grinding the average hardness corn dried at 80 °C by roller mill at 0−0 roller-gap yielded a greater d gw than similar corn dried at 35 °C, but a different response was observed for the harder kernel corn. For hard kernel corn ground by the 30−30 roller-gap, drying at 35 °C produced larger particles than drying at 80 °C.
