Converting a Batch Heater to Continuous Flow

What's Your Grant Score?

Example of an old batch dryer

  In this hypothetical situation a farmer has yields of 170 bushels an acre of corn and farms 600 acres. This would mean he:

  • Dries 100,000 bushels
  • Current system uses 2,900 btu/lb. at 10 pt
  • System uses $32,000 to dry
  • (2900btu/lb. *7.42lb ( 10pt)* 70% energy usage*100000 bushel)/ 91,500 BTU/GAL = 16,461 gallon = $32,000


Proposed system: 1216 dryer

    • With Heat reclaim

    • 8� auger/m24' leg

    • Use $16,000 propane

      • 20-15 pt reduction

      • Propane @ $2 gallon

    • Cost $70,000 installed



    1216 Return On Investment (ROI)

      • Initial ROI = $16,000 / $70,000 = 23%

      • Simple payback = $70,000 / $16,000= 4.3 years

        • System costs hypothetically $70,000 before grant

        • Energy savings

          $32,000

          -
    $16,000
    $16,000

    1216 system Cash-Flow

      First Year Cash flow +++ $18,760

    • True cost = $70,000- $17,500 grant = $52,500
    • Annual payment @ 7% for 7 years = $9,740
    • Annual depreciation = 70,000/2*35% = $12,250
    • Cash flow
      • $16,000 energy savings
      • + $12,250 Tax savings
      • � $9,740 loan payment
      • = $18,760
