Energy costs for corn drying and cooling

2 天前  Grain needs to be dry to be stored through warm weather, but it takes energy to remove moisture from grain. Fortunately, there are things growers can do to estimate the costs of drying and cooling corn and manage energy use. Gas-fired drying Energy use per bushel per percentage point of moisture removed for gas-fired drying varies widely among dryers. Plus, the percent of moisture to be ...

Cost of On-Farm vs. Commercial Grain Drying

2019-10-30  As you can see, if a commercial drying facility is using a drying rate of $.04/point of moisture the breakeven price of LP for your on-farm drying is $2.00 gallon. Most LP prices across the country are under $1.00 and I know of a material amount of LP bought at $.50 or less. As an aside, when prices are at extremes throw seasonality out the window!
