  1. HEAT TREATMENT PERSPECTIVE / EXPERIENCES NAPERVILLE, IL Post Cereal Plant Deb Krug-Reyes HEAT TREATMENT WORKSHOP August 7, 2001 Kansas State University Department of Grain Sciences

  2. Naperville Heat Treatment Experiences • Why Heat Treat • Naperville Plant HT Timeline • Continuous Improvements • Lessons Learned • Future Plans

  3. Naperville Heat Treatment Experiences WHY HEAT TREAT: Advantages: - Alternative to Methyl Bromide - Environmentally Friendly / Good Neighbor - No need to evacuate building - Some operations can continue in plant concurrently - Experience has shown good kill-- potentially better than fumigation - Less stringent building sealing requirements - Cost effective after initial investment

  4. Naperville Heat Treatment Experiences WHY HEAT TREAT: Disadvantages: - Still need to chemically treat non-heat treated areas (vs. entire plant fumigation) - Potential structural or equipment damage if temperatures significantly exceeded - Some additional preparation (remove computer controllers, other sensitive electrical)

  5. Naperville Heat Treatment Experiences • HEAT TREATMENT TIMELINE: • 8/99 Q.Mgr + Sanitarian attend K-State HT Workshop • 3/00 Naperville plant trialed 1st HT with electric rental units-- treated 7 mill rooms + inside silo (bin rooms) • 1/01 Naperville plant installed steam drops, and prepared several areas for HT w/ KF • 3/01 Observed Champaign plant HT with portable shared heaters • 4/01 Performed HT in refuse / animal food compactor area • 6/01 Performed HT in inside grain use and weigh bin areas • 7/01 Performed HT in inside grain silo rooms (bin rooms) • 8/01 Performed 2nd HT in inside grain silo rooms

  6. Naperville Heat Treatment Experiences • CONTINUOUS IMPROVEMENTS: • Improved temperature control • - Increased air movement (fans, fans, more fans) • - Improved heater, and fan positioning, more ducts • Better sealing methods • Improved temperature monitoring • - Continuous data loggers • - Temperature probes w/ digital remote box • - Non-contact thermometers (NIR guns) • - Insect check cards • Ongoing support from IFC

  7. Naperville Heat Treatment Experiences • LESSONS LEARNED: • Air circulation / fan placement is key to getting uniform temperatures • Need better sealing of outside vents / doors with inclement weather • Check fire doors for temperature rating • Avoid overheating, watch for hot spots • Get maintenance and sanitation staffing commitment for HT schedule • Document structural damage before heat-up • Perform as much detail cleaning in advance as possible • Coordinate confirmed time schedules with production

  8. Naperville Heat Treatment Experiences • FUTURE PLANS: • Continue HT in designated areas • Explore potential of getting permanently installed heaters in specific areas • Work with experts to detemine feasibility of HT in other plant areas • Plan to trial heating an individual piece of equipment • Continue to work with plant and corporate engineering to pursue short and long term strategy
