Two steps with one machine: The Kahl crown expander not only expands compound feed or individual components, but also shapes them simultaneously. This makes it possible to produce expanded and, at the same time, shaped products such as pellets for all animal species.
The aim of the engineers at Amandus Kahl was to design a new expander based on the worldwide and well-known Kahl Annular Gap Expander, equipped with a die at the outlet and a cutting device. An important component of the Annular Gap Expander also remains unchanged in the Crown Expander: The hydraulically movable cone, which is moved like a piston into the crown tool end.
The pressure is approxiately 40 bar; the operating temperatures at the expander outlet are between 90 and 140°C. At the expander outlet, the pressure drops spontaneously. The product expands, and a part of the added water evaporates (flash evaporation). The size of the expanded particles or pellets can be determined by means of knives or dies.
