5. Canadian Grain Commission approved sample dividing equipment
A Boerner-type divider is the only divider approved for use by the Canadian Grain Commission. It is a gravity-operated dividing apparatus that reduces a grain sample to smaller equal portions. The sample is placed in the upper hopper and released by opening the valve located in the hopper throat. The sample flows downward and is evenly dispersed over a cone with evenly spaced separations. The divided sample is then directed into two grain streams which empty into two collecting pans at the bottom.
