groundnut decorticator full working ppt
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.Probably hundreds of different decorticators have been developed since 1890.Misconceptions spread about the device includes the suggestion that the first working hemp decorticator was invented in the United States in 1935. In 1916, there were already five different kinds of "machine brakes" for hemp in use in the United States, and still others in Europe.
