Grain samples to be inspected are collected by
a Diverter-Type (D/T) Sampler, which is located
either before or after the scale. Once every
sampling interval (usually set between 12 and 25
seconds) a motor sweeps a sampling container
called a pelican through the grain stream.
A pipe coming out the bottom of the pelican
drops the grain sample into a collecting funnel.
It then flows through a pipe to the inspection
lab, where it is graded. A secondary sampler (not
shown) divides the sample between the Federal
inspection lab and the elevator's quality control
