An old engraving of a large grain hulling machine of the 1800s. It is from a Victorian mechanical engineering book of the 1880s. Grains such as rice required a huller or husker to mechanically remove the chaff (the outer husks) of the grains. Traditionally, it would be pounded using some form of mortar and pestle. The Engelberg huller, designed by German Brazilian engineer Evaristo Engelberg in Brazil and first patented in 1885, used steel rollers to remove the husk. Here the huller uses abrasive rotating conical abrasive disks to first remove the husks.
