Separating the wheat from the chaff

Breads, cakes, and cookies are all generally made from wheat.  It all begins with the sowing of seeds, reaping the mature wheat, thrashing the stalks, winnowing and milling.

Wheat is harvested with it turns a golden colour.   The grain is dried to allow it to fully ripen.  The grain next needs to be removed from the stalk by beating the ripe wheat stalks.  This is known as "threshing".  As the grain falls off the stalks, the stalks - now called "straw" - are discarded or may be used for animal feed or bedding.

The next step involves removing the wheat from the chaff.  All grains have chaff that needs to be removed before it can be further processed.  Chaff is the dry, scaly protective cover over cereal grains.

For thousands of years, the chaff was removed by tossing the grain and chaff into the air on a windy day.  The wind would blow away the chaff allowing the heavier grain to fall to the ground.  This is called "winnowing".   In some countries, this method is still used.

Sometime during the 19th century, a "winnowing" machine was invented to make the task easier.  Wheat and chaff was fed into the machine.  A set of wheels and pulleys operated a big blower and sets of shakers. 

Note the hand painted folk art painted onto the 1910 Winnowing Machine/Seed Separator. 

During modern times, farmers use "combine harvesters"  for three harvesting operations.  The combine reaps (cuts) the wheat, threshes and winnows.

 

A great video about how a thrasher works can be found at the Living History Farm website.

This antique combination threshing and winnowing machine was built and used in 1910 in Ontario, Canada.  The machinery still works and is currently used for display at agricultural fairs.

The mechanisms run on a system of pulleys powered by a gasoline engine.  The steam that is emitted from the motor is from water used to cool the engine.

A "shock" (bundle) of dried wheat are loaded into the threshing machine.  The wheat is placed in a top loading tray where it falls onto rollers with gears that separate the kernels from the stalks.

Conveyor belts carry the stalks and wheat kernels through the machine.  Slots allow the wheat kernels to fall into a hopper.  The belts in this particular model are made of canvas with leather trim.

Agriculture

Agriculture is the science or practice of farming, including the cultivation of the soil, the production of crops and the raising of livestock for food, wool and other products.

 

 

 

 

 

"Cultivators of the earth
are the most
valuable citizens.
They are the most
vigorous,
the most independent
the most virtuous,
and they are tied
to their country
and wedded to its
liberty & interests
by the most
lasting bonds."

~ Thomas Jefferson ~

 

 

 

 

 

 

"There seem to be 
but three ways 
for a nation 
to acquire wealth.  
The first is by war, 
as the Romans did,
 in plundering their 
conquered neighbours.  
This is robbery.

The second by commerce, 
which is generally 
cheating.

The third by agriculture, 
the only honest way 
wherein man receives 
a real increase 
of the seed thrown 
into the ground, 
in a kind of continual miracle, wrought by the hand of God
 in His favour, 
as a reward 
for his innocent life 
and his virtuous industry."

~ Benjamin Franklin ~

 

 

 

 

 

 

"The diligent farmer 
plants trees, 
of which he himself 
will never see the fruit."

~ Cicero ~

 

 

 

 

 

"Farming looks 
mighty easy 
when your plow 
is a pencil,
 and you are 
a thousand miles 
from the corn field."

~ Dwight D. 
Eisenhower ~
