  2. Soybean ground pile?!

  3. Got Storage ?! Stored Grain Management • Sanitation • Bin Loading practices • Aeration • Safe Monitoring • Web sites for other information

  4. Sanitation Equipment • Combine(s) • Carts/truck beds • Handling equipment • Dryers • Bins

  5. Sanitation Outside the bins • Remove spilled grain • Mow weeds to reduce rodent activity

  6. Sanitation Inspect bins • Look for daylight shining through holes in roof and walls • Seal bottom ring to prevent air leaks • Repair as needed

  7. S.L.A.M. Stored Grain Management • Sanitation • Bin Loading practices • Aeration • Safe Monitoring • Web sites for other information

  8. Bin Loading Don’t overfill the bin

  9. Bin Loading • Manage trash and fines • Control grain damage by combine • Run augers full and ASAP • Clean grain before storage • Use a spreader to fill the bin • Core the bin to remove fines/trash from the center

  10. Manage Trash and Fines

  11. Core after Filling to Remove BCFM

  12. Moisture Migration in Winter 45OF 65OF

  13. Grain Spoilage from Moisture Migration • Uniform Temperature • Prevents moisture migration • Preserves product quality

  14. S.L.A.M. Stored Grain Management • Sanitation • Bin Loading practices • Aeration • Safe Monitoring • Web sites for other information

  15. Stored Grain Temperatures in KY

  16. Aeration Cooling Cycle

  17. Estimated Time for Aeration Cycles (Hours) hp / 10 kbu 1 hp 5 hp 10 hp

  40. Thanks for your attention… Questions?

  41. What is REAP / GOAP? • The Rural Energy for America Program (REAP) is offered through the USDA Rural Development • The Kentucky Ag Development Fund provided money for state projects • Provides assistance to agricultural and rural small businesses for energy efficiency improvements or renewable energy installations

  42. Past Projects—Example 1 • Grain Dryer  Controller upgrade • $3,078 per year savings • 14.0 year payback • Controller upgrades typically yield better paybacks due to lower initial cost and high price of over drying grain

  43. Past Projects—Example 2 • Grain Dryer  Replacement of old dryer with new energy efficiency model • $1,431 per year savings • 20.2 year payback Old Dryer New Dryer
