  • Ethanol ProductionDry versus Wet Grind Processing —

    While dry milling is less capital intensive it also yields less ethanol per bushel of corn than wet milling (Rajagopalan et al. 2005). Wet milling involves steeping the corn for up to 48 hours to assist in separating the parts of the corn kernel. Processing the slurry separates the germ from the rest of the kernel which is processed further

  • The influence of pre-fibrillation via planetary ball

     · A planetary ball milling was applied as a pretreatment of chitin powder to prepare precursors for chitin nanofiber (ChNF) production. The study aims to examine the effects of ball milling conditions (dry milling and wet milling in neutral and acidic aqueous medium) on the degree of pre-fibrillation of the ChNF precursors and the characteristics of the resulting nanofibers.
