  1. Deluxe Ice Cream Bar Freezer Pack:Feasibility and Costs Stephanie Bezilla Sarah Burch Britt Smart Lizalyn Smith Freezemore, Inc. Freezemore@umich.edu

  2. Frozen Dessert Industry • $20.3 Billion/Year Industry • 91% U.S. Households Consume • 50% Sold in Supermarkets; 50% Sold in Retail Outlets (Restaurants, Parlors) • 1.6 Billion Gallons Produced/Year • 5.7 Gallons/Year Consumed per Person Freezemore, Inc. Freezemore@umich.edu

  3. You Want It, We Got It Objective • Motivation • Increase Ice Cream Bar Sales Volume • Increase Klondike Market Share in Frozen Dessert Industry • Problem • Feasibility of 5-6 Hour Individual Bar Cooler • Estimate Manufacturing and Testing Cost Freezemore, Inc. Freezemore@umich.edu

  4. Assumptions • Klondike Deluxe Ice Cream Bar • -5°C to 0°C Ideal Ice Cream Service Temperature • -10°C to 0°C Typical Freezer Temperature Freezemore, Inc. Freezemore@umich.edu

  5. Ice Substitute Equilibrium: 3 Hours at 25°C Ice with Salt Equilibrium: 0.5 Hour at 18 °C Cooling Refrigerant:Ice Substitute Outperforms Ice *At Test Start, Ice Substitute Was Not Completely Frozen Freezemore, Inc. Freezemore@umich.edu

  6. Test Set-Up Freezemore, Inc. Freezemore@umich.edu

  7. Future Testing:CMC Based Gel Pack (Sodium Carboxymethylcellulose) • 6 Hour Prototype Test • Ice Cream Bar • 2 CMC Gel Packs • Final Temperature Equal to 0°C • Heat Transfer Analysis of Final Design Freezemore, Inc. Freezemore@umich.edu

  8. 5-6 Hour Cooler is Feasible • First Law of Thermodynamics • Heat Flow Rate is Conserved Qice = miceciceΔT = QH20= mH20cH20ΔT cice = 23500 J/kg-K Freezemore, Inc. Freezemore@umich.edu

  9. 5-6 Hour Cooler is Feasible • Ideal Ice Volume Calculation Above Equation Yields Ideal Ice Volume of ~8E-5 m3 (4.9 in3) • FreezeMore Ice Volume = 1.42E-4 m3 (8.7 in3) Freezemore, Inc. Freezemore@umich.edu

  10. 5-6 Hour Cooler is Feasible • Assumed No Phase Change of Ice Substitute • Ice Cream and Ice Modeled as Same Temperature • Convection Eliminated in Cooler Compartment (No Air Inflow) • Radiation Negligible Due to Insulation Styrofoam (No Perceptible Outside Coolness to Container) Freezemore, Inc. Freezemore@umich.edu

  11. Cost Analysis • 2 Month Promotion Time • Late Spring Optimal • Cooler Attached to Each 6-Pack • Estimated 5 Million (6-Packs) Sold During Promotion Time Freezemore, Inc. Freezemore@umich.edu

  12. Manufacturing Cost $0.67 per Unit * Initial Capital Investments Not Included in Cost Estimate Freezemore, Inc. Freezemore@umich.edu

  13. 25% Growth in Sales • 80% of People Initially Surveyed Would Use Cooler • For Each Free Cooler, At Least One More Six-Pack Would Be Sold • Increase in Sales by 5,000,000 Six-Packs • Increases Klondike Sales by 25% Freezemore, Inc. Freezemore@umich.edu

  14. What Would You Do For A Klondike Bar?:Recovering Cooler Cost • $0.17 Added to Six-Pack for 1 Year Covers Manufacturing Costs • Money Due to Promotion = Profit!!!! Freezemore, Inc. Freezemore@umich.edu

  15. Cost/Benefit Ratio FreezeMore Has Positive Rating! Freezemore, Inc. Freezemore@umich.edu

  16. FreezeMore Cooler Prototype • CMC Gel Pack • High Density Polyethylene Plastic Outer • Klondike Ice Cream Bar • Styrofoam • Rubber Seal Freezemore, Inc. Freezemore@umich.edu

  17. CMC Gel-Pak Benefits • Non-Toxic • FDA Approved for Food Use • Durable • “True Gel” (Permanent Phase Change) • No Gel Deterioration Over Time • Efficient • 20% Greater Cooling Capacity Than Ice Freezemore, Inc. Freezemore@umich.edu

  18. HDPE Plastic Outer Benefits • FDA Approved for Food Storage • Inexpensive ($0.32/lb) • Freezes Well (Up to -70°C) • Low Conductivity • Strong (Yield Strength = 21.8 MPa) • Can be Injection Molded Freezemore, Inc. Freezemore@umich.edu

  19. Klondike Ice Cream Bar • Cooler Made Specifically to Size of Ice Cream Bar • Increases Brand Loyalty • Increases Repeat Buyer Volume Freezemore, Inc. Freezemore@umich.edu

  20. Styrofoam Insulation Benefits • Low Conductivity (k=0.25 W/m-K) • Inexpensive ($0.04/unit) • FDA Approved for Food Storage Freezemore, Inc. Freezemore@umich.edu

  21. Conclusions • 5-6 Hour Cooler is Feasible • Estimated Manufacturing Cost per Cooler is $0.67 • Cost Recoverable with Six-Pack Price Increase of $0.17 for One Year • Estimated 25% Growth in Sales • Recommended Prototype Materials *CMC Gel Pack *HDPE Plastic Outer *Styrofoam *Klondike Ice Cream Bar Freezemore, Inc. Freezemore@umich.edu

  22. Questions? Proposed FreezeMore CAD Design FreezeMore Prototype Freezemore, Inc. Freezemore@umich.edu
