  1. Coconut Sweetening Process Elizabeth Casey Justin Dillingham Mohd Hussain Brady Stewart BAE 4012 – Fall 2005

  2. Mission Statement • Palm Tree Processing is a consulting group that strives to help family owned and operated food businesses achieve the highest quality food products available.

  3. About Griffin Food Company • Founded in Muskogee, OK in 1908 by John T. Griffin • Major products available • Syrups • Jellies and preserves • Mustards • Coconut flakes

  4. Coconut Flakes • Popular confectionary product • Enhances food properties • Texture • Flavor • Visual appeal

  5. Before After Problem Definition • Consumers demand the longest length of coconut flakes possible • Flake length of Griffin’s coconut degrades during processing

  6. Project Goals • Pinpoint and quantify degradation • Make recommendations to: • Prevent flake length degradation • Increase processing capacity • Improve quality of work for employees

  7. Process Steps • Delumping • Conveyance to cooker • Cooking and blending • Tempering • Packaging

  8. Delumping • Clumps of coconut form during storage • Delumper used to separate clumps • Rotating spikes • Employee designed and built

  9. Delumper

  10. Conveyance to Cooker • Auger transports coconut from delumper to cooker • Contained within PVC pipe • Frequently clogs • Limits processing speed

  11. Cooking and Blending • Double ribbon agitation cooker • Blends slurry, sugar and coconut • Runs continuously during delumping and conveying

  12. Tempering • Barrels store coconut overnight • Allows for uniform moisture distribution • Large clumps often form

  13. Packaging • Barrels unloaded • Extensive manual labor required • Auger conveys coconut to packaging machine • Frequently clogs

  14. Design Criteria • Recipe may not change • Production capacity must not decrease • Simple transition from existing to improved process line • Minimal cost

  15. Concept Development • Quantifying coconut flake length • Modified ASAE Standard S424 • Image Analysis with MatLab • Potential Solutions • Proposal A – Steam Injection • Proposal B – Replacement of Auger Conveyor • Proposal C – Replacement of Cooker

  16. Modified ASAE Standard S424 • Sieves separate coconut flakes • Average geometric mean length calculated using: Xgm = geometric mean length Xi = geometric mean length of particles on ith screen Mi = mass on ith screen

  17. Picture taken of coconut flake sample Average flake length calculated with MatLab Morphological Operations in Image Processing Package Image Analysis with MatLab

  18. Results

  19. Results

  20. Proposal A – Steam Injection • Steam injected into bags of coconut to break up clumps • Replaces delumping and conveying process steps • Pros • Less handling of coconut • Cons • May change coconut properties

  21. Pneumatic Conveyor Pressurized air moves coconut flakes Pros High capacity Minimal stress on product Cons High power requirement Bucket Conveyor Buckets carry coconut flakes Pros High capacity Gentle on product Cons Maintenance Proposal B – Replacement of Auger Conveyor

  22. Proposal C – Replacement of Cooker • Replaces cooker with tumble blender • Rotating chamber mixes ingredients • Types of tumble blenders • Slant-Cone • V-Shaped • Double-Cone

  23. Proposal C – Tumble Blenders Slant-Cone • Pros: Fast and uniform blending • Cons: Requires large headspace V-Shaped • Pros: Efficient blending • Cons: Difficult to clean Double-Cone • Pros: Minimal space requirements • Cons: Longer blending time

  24. Spring Schedule • Continued development of flake length measurement methods • Further investigation of proposals • Evaluation and testing of proposals • Final recommendations
