1 Creation of Bulk Products and its Properties GMF-Gouda Gouda Germany GmbH Dipl.-Ing. Alexander Kuppe Contents GMF-Gouda Processes (Drying - Solidification) Product properties Process Solutions Example: MA-Solidification Example: PEG-Flake line The Pilot plant GMF-Gouda History 1909: Founded in the center of the city of Gouda 1916: First Drum Dryer 1920s: First Drum Flaker 1983: First Paddle Dryer 1989: New factory 1994: Disc Pastillator... still 100% family owned 1

2 GMF Gouda - Today Active worldwide: Netherlands (HQ) France Germany Singapore China USA (2x) GMF-Gouda Facts and Figures 180 employees Turnover: EUR ~ 30 Mio. Focus on Turnkey-Projects Service-orientation Turnover by Region Turnover by Technology Europe Far East USA Others Dryer Crystallizer Other Product Properties - Drying Final Moisture Particle Size & Size Distribution ( Fines ) How about Solidification/Crystallization? 2

3 Solidification / Crystallization Drum Flaker (since 1920s) Disc Pastillator (since 1994) Jet-Priller ( ) Solidification Process Pre-Process Process e.g. Reactor Destillation column Solidification e.g. Drum Flaker Disc Pastillator Jet Priller Solid modification e.g. Mill Sifter Briquetter Screw conveyor Packaging e.g. Bags Big Bags Barrels Converting molten Products into Free Flowing Solids Objectives Functionality of Product Easy Handling (Dosing, Conveying etc.) Safe Storage (Bulk density, temperature etc.) Safe Transport Appearance No Dust??? Choice of product form Flakes Pastilles Prills Granules - Powder Briquettes

4 Principle of the Drum Flaker Adhesion Growing layer Second layer Crystallization Further Cooling Scrape off Principle of the Drum flaker Features of the Drum Flaker Simple process: Simple operation Long lifetime Machine can be encased Toxic, smelling products Inertisation possible Sublimating products Completely closed cooling circuit Compact equipment Low energy consumption 4

5 Principle of the Disc Pastillator Dosing / Feeding Pastille Formation Crystallization and cooling Pastille scrape-off / discharge Features of the Disc Pastillator Machine can be encased Toxic, smelling products Inertization possible Sublimating products Completely closed cooling unit Compact equipment Low energy consumption Uniform Pastilles Example: MA Solidification Installations in Hungary and China Objective (Market requirements) Free Flowing Dust free No lumps Question Most efficient technology: Pastillator versus Flaker+Briquetter 5

6 MA-Solidification Lay-out Disc Pastillator Single Machine Max. Capacity ~ 1.2 t/h/pastillator MA-Solidification Lay out Drum Flaker + Briquetter Complete Line Max. Capacity ~ 8 t/h/ Line 100 MA-Solidification Investment comparison Investmentmt Drum Flaker & Br Disc Pastillator Capacity t/hr Capacity determines the Equipment 6
