Because
bad weather can damage the wheat crop, farmers use huge machines
called combines to cut the stalks
and separate the kernels from the rest of the plant.
After
the harvest, most farmers
haul their wheat in trucks to a country grain elevator for storage.
The grain from each truck is emptied into a pit. A conveyer belt
then picks up the grain, and carries it to the top of the elevator.
The grain is then dumped into a tall storage bin. The grain is
dried and cleaned. Workers give one of six grades to the wheat,
based on its weight and its quality. Wheat is sold based on its
grade.
Wheat
then travels by truck or railroad boxcar to an elevator located
in a large grain market or shipping center. If the grain is to
be exported, the United States Department of Agriculture inspects
and grades it.
Some
wheat is then loaded onto ships for export. In other words, the
wheat is sent to other countries. Trucks, railroad cars, or barges carry the remainder
of the wheat to mills for grinding into flour. The rest is shipped
off to other processors to be used in animal feed or other industrial products. Some
wheat is bought directly from farmers, or buyers may purchase
wheat already in storage.
