Husker

A rice huller or paddy husker is an agricultural machine used to automate the processing of removing the chaff (outer husks) of rice grains. Throughout history, there have been numerous techniques to hull rice. Traditionally, it would be pounded using some form of mortar and pestle. An early simple machine to do this is a rice pounder. Later even more efficient machinery was developed to hull and polish rice. These machines are most widely developed and used throughout Asia.
