Information about storing grain.

How high can I store grain?

Grain is usually stored approx 8 -12 feet deep.

What size should my Fan be?

Usually half of a grain store is dried at one time. Fan size should be big enough to supply 100cfm per tonne of grain being dried and have enough back pressure.

Tunnel Size?

Your tunnel should be strong enough to withstand the pressure from the grain and big enough to support a max air speed of 2000ft/min.
