Breakage of rice during milling - comparison among different shellers.

A medium-long, semislender variety of paddy was shelled using four
types of shellers (rubber roll, centrifugal, disc under-runner, McGill) followed
by pearling with a McGill miller. Grain breakage during shelling
was the least in the rubber roll. But the less the breakage duringshelling,
the more it was during pearling. As a result, the rubber roll gave considerable
advantage after low and medium degrees of milling, but only a marginal
advantage at high milling. Total rice breakage was equal to or less
than the content of defective grains in the original paddy depending on
the sheller.
