Rice Hulling Rolls

position of rice hulling roll inside the huller machineNIRI rice hulling rolls are used to remove the husk from brown rice, that is why it is also called rice husking roll or rice husker. Rice hulling roll is also called rice rubber roller. Two of these rubber rolls are installed in a rubber-roller huller. This machine is known as the most efficient hulling machine as it yields minimum broken or cracked grain.

NIRI rice hulling rolls are available in several sizes which differentiate the hulling capacity of the rubber rolls. In one rubber-roller huller, two rolls of the same size are installed as shown in the figure. However, these rolls operate at different speeds in order to remove the husk. To achieve maximum efficiency, the hull must be dried until 14% moisture content is reached.
