Martinsville, Ohio | Moisture Shrink
The removal of moisture from grain during drying causes a reduction in grain quantity referred to as moisture shrink. The moisture shrink can be calculated using the following equation.
Moisture Shrink (%) =
Initial Moisture Content -
Final Moisture Content
----------------------------- x 100
100 - Final Moisture Content
The moisture shrink percentage for drying corn from 25 to 15 percent moisture content is:
Moisture Shrink (%) =
25 - 15
-------- x 100 = 11.76%
100 - 15
The weight reduction drying 1000 pounds of corn from 25 to 15 percent moisture content is 11.76% x 1000 = 117.6 pounds. Moisture shrink tables AE-94, "Grain Drying Tables," are available from the NDSU Extension Service.
Refer to NDSU Extension Circular AE-905, "Grain Moisture Content Effects and Management," for more information on moisture
Scott, you could be right, have to check again but still sounds like a good deal:
He suggests using the following formula to estimate the cost of propane for high-temperature drying: cost/bu-pt (cost per bushel per percentage point of moisture removed) = 0.022 x propane price/gal. For example, the drying cost is $0.022/bu-pt if the cost of propane is $1 per gallon (0.022 x $1). Removing 10 percentage points of moisture from 120 bushels of corn using $1 propane will cost about $26 (120 x .022 x 10).
The estimated quantity of propane needed for drying is 0.02 gallon per bushel per point of moisture removed. For example, 24 gallons of propane is needed to dry 120 bushels of corn from 25% to 15% (0.02 x 120 bushels x 10 points). This is based on 0.72 pound of water being removed per point of moisture per bushel, 2,500 British thermal units (Btu) of heat required to remove a pound of water in a high-temperature dryer
