Converting Dry and Cool to a Tower Drier

What's Your Grant Score?

Example of a Dry and Cool

In this hypothetical situation, a farmer currently has yields of 170 bushels per acre of corn and farms 2400 acres. He:

  • Dries 400,000 bushels
  • Currently uses 1,600 btu/lb. BTU/lb. (pt) of drying
  • Currently uses $72,000 to dry = 18 cents/ bushel
  • (1600btu/lb. *7.42lb (10pt)* 70% energy usage*400,000 bushel)/ 91,500 BTU/Gallon = 136,000 gallon = $72,000


Proposed system: T1575 tower dryer

  • Grain invertors

  • Outside cat walk

  • Stainless steel grain floor

  • Use $47,000 propane

    • Propane @ $2/gallon

  • Cost $175,000 installed



T1575 Tower Dryer return on investment (ROI)

  • Initial ROI = 14%
    $25,000 / $175,000 = 14%

  • Simple payback = 7 years $175,000 / $25,000 = 7 years

    • Energy savings

    •  $72,000
      -$47,000
      $25,000
    • System costs $175,000 before grant


T1575 Tower System Cash Flow

  First Year POSITIVE Cash flow + $30,625 True cost = $175,000- $43,000 grant = $132,000

  • Annual payment @ 7% for 7 years = $25,000
  • First year depreciation = 175,000/2*35% = $30,625
  • Cash flow
    •    $25,000 energy savings
    • + $30,625 tax savings
    • – $25,000 loan payment
    • = $30,625
