Petfood safety and shelf life is as closely monitored as humans food is. Ingredients and formulas for cats and dogs food are various and they have been increased significantly lately, therefore the controls during the production processes are getting more and more important.
Exactly like human food, the drying processes - that comes after the kibbles are extruded - are energy requiring and needs to be controlled precisely. Therefore the inline bulk density and moisture measurement before and after the dryer are crucial to fulfill the requirements and to keep the costs low.
Microwave resonance technology is a very precise, reliable and cost effective measuring method for this application, it has been proven since decades and already installed in many production lines all over the world.
