In early October, 28 dryer customers from around the world, a record number, participated in Geelen Counterflow’s Dryer & Cooler Training 2018. Dryer customers from Ecuador, Peru, Japan, China, Thailand, Indonesia, Nigeria, Denmark, France, Serbia and Poland learned how to optimize their counterflow dryers for extruded aquafeed or petfood for best efficiency, uniformity and lifetime.
This was the 11th year Geelen Counterflow organized this training. During the 3 day training, participants go back to school to learn about the thermodynamics of drying and cooling, relative humidity, dew point temperatures, wet bulb temperatures, mollier diagrams, enthalpy, sorption isotherms, diffusion coefficients, radiation, convection and so on.
The training days always start with theory and in the afternoon participants follow four different workshops about dryer process calculations, dryer controls, air systems, and process measurement.
In addition to learning about the thermodynamics, subjects include sanitation, condensation control and sustainability.
Evening programs are filled with social activities. There are also plenty of networking opportunities with colleagues from around the world. Over the years more than 200 dryer customers have followed this course. The next Dryer Training for Geelen Counterflow dryer customers will take place in Haelen, the Netherlands in October 2019.
