Products and machines

Tietjen presents its new developments for the feed and petfood/aquafeed industries at VICTAM International in Utrecht, Netherlands.
The large chamber mill FD, the AGS AD Air-Gravity Separator AGS AD, and the Online Particle Size Controller OPC, all three increase the efficiency of the grinding process.


Research and development

The amount of plastic waste is increasing from year to year. Biodegradable packaging is therefore becoming increasingly important, and not only in the food industry. Yet there are already many sustainable packaging alternatives – such as bio-film made from macroalgae. Since this process is very time-consuming and expensive, Ludwig Schmidtchen, a doctoral student, has developed a cheaper and faster manufacturing process for this film. He received help from Tietjen.
