SDET Extruder

Münch extruders are simple and maintenance reduced constructions for the treatment of grain, fish feed and petfood. With this treatment of compound feed in the form of meal, the food is mechanically suspended in a pressure vessel at high water steam adding with high pressure. Whereas, temperatures of up to 130 °C and a pressure up to 50 bar during a contact time of 5 – 10 sec are reached. Like in a cooking process these conditions change starch and proteins and thus increase the digistibility. Potentially contaminated indigestive substances are destroyed. The most pathogenic bacteria are killed.

The treated material is then pressed through a die, whereas – for this procedure – the typical slightly foamy structure of the compound feed arises. In the production of pet food for dogs and cats, but also in the fish feed production this process is often implemented.
