Down and Dirty: Giving Back The Tare Dirt

Harvesting Sugar Beets brings along dirt


Sugar beets are a root crop. Just like carrots, turnips, radishes, and potatoes, the part you want is in the dirt – not on a tree or bush. So harvesting involves dirt. Mechanical harvesters dig the beets out of the ground and throw them into a truck at a pretty high speed so a lot of dirt goes along for the ride and into the piler. This dirt is called “Tare Dirt”. American Crystal Sugar does not want the dirt, has no place to keep it, and certainly does not want to pay for it. It is part of the truck weight coming into the yard and they want it to be part of the truck weight going out.

Pilers include large cleaning devices to carry out a secondary cleaning of the beets to remove all foreign materials that made it into the piler with the beets. Beets are bounced and rolled, being scrubbed clean as they move; dirt and other foreign materials are sucked through the rolls, collected into a hopper, and returned to the truck as the last step in the receiving process.

Piler cleans off some of the dirt ...


... and that dirt is returned to the truck

By this time loose dirt is gone and the beets are “pretty clean”, but they still carry some clinging tare dirt through the piler. The beets are subject to a deduction for that tare dirt. Tare determination, sugar percentage, and sugar loss to molasses are determined based on the sample at the quality laboratory in Grand Forks.

That’s the story on Tare Dirt.
