Raw
Materials--- The raw stock for our corncob
bedding products is 100% corncob. No other components or
additives are used. The 1/4" and 1/8" products
are produced from only the woody-ring portion of the corncob
and the pelleted corncob is produced from the pith and
chaff (beeswing) portions.
Processing Procedures ---
As the raw stock corncobs are introduced to the plant,
they pass through a hammermill that produces corncob
fractions. The corncob fractions are then heat-dried.
The drying process utilizes a rotary dryer system
that heats the corncob fractions to approximately
200º F for two to three minutes. An aspiration
process separates the woody-ring portion of the corncob
from the pith and chaff portions. Smaller fractions/particles
are produced by rollermill and hammermill processes.
The particles are then sized and separated through
a sifting process which utilizes screens conforming
to U.S. standards. The particles pass through a final
aspiration process to remove any remaining dust and
are then placed in overhead storage until packaged.
The pith and chaff portions are processed through
a pellet mill to produce the pelleted corncob product.
Plant operating procedures require a minimum testing
frequency of twice per shift for measuring moisture
content and particle size distribution.
