Decorticator

A decorticator (from Latin: cortex, bark) is a machine for stripping the skin, bark, or rind off nuts, wood, plant stalks, grain, etc., in preparation for further processing.

In 1861, a farmer, named Bernagozzi from Bologna, manufactured a machine called a "scavezzatrice," a decorticator for hemp. A working hemp decorticator from 1890, manufactured in Germany, is preserved in a museum in Bologna. In Italy, the "scavezzatrice" faded in the 1950s because of monopolization from fossil fuel, paper interests, synthetic materials and from other less profitable crops.
