In 1933, a farmer named Bernagozzi from Bologna manufactured a machine called a "scavezzatrice", a decorticator for hemp.
[2] In Italy, the"scavezzatrice" faded in the 1950s because of monopolisation from fossil fuel, paper interests, synthetic materials and from other less profitable crops.
[citation needed] In 1919, George Schlichten received a U.S. patent on his improvements of the decorticator for treating fiber bearing plants.
[3] Schlichten failed to find investors for production of his decorticator and died in 1923, a broken man.
[4][5] Newer, high-speed kinematic decorticators, use a different mechanism, enabling separation into three streams; bast fibre, hurd, and green microfiber.
