Screws element is used for food or plastic granulation, essentially mixing and extruding products, but there are many differences between them.
First of all, there are great differences in screw materials, the materials for food-grade screw elements should meet the relevant food safety requirements, such as In Regulation (EU) No. 10/2011 on plastic materials and articles intended to come into contact with food. The specific migration of heavy metal has been placed clearly.
Secondly, the choice of structure is quite different, the Food& feed extruder needs to keep more nutrient elements with a lower temperature, so the structure is quite different from the screw for plastic extruder. It uses very few mixing elements and kneading elements.
