Rice huller

An old-type mechanical huller, driven by a gasoline engine

An electric rotary huller

A huller (or called rice husker) is a kind of agricultural machinery to hull the rice.

There were many ways of hull the rice (which means to remove chaffs (the outer husks of the grain)) from ancient times, but nowadays a huller, or sometimes called rice huller is widely used in Asia, especially in Japan because rice is treated as a most important crop, so that a huller has been developing in more sophisticated ways than any region in the world.

Types of the machine

• A rotary huller

This type of the machine gets the brown rice in good quality by a cylindrical sieve set inside the body.

• A swing huller

By swinging a set of sieves, it separates the brown rice.

• A mangoku-siki (万石式) huller

"Mangoku" was first developed during the Edo period in Japan, and which is still a most efficient way of grading harvested rice. A newest model "Elec-Huller" released by a Japanese company can even handle its process with a full-automatic system by a micro-computer.

These machines now are driven by a gasoline-engine or electric motors, and often controlled by micro-computers.
