Preconditioner for better control of operating parameters

Preconditioners can improve productivity, ?quality and allow greater flexibility in ?controlling process parameters. Trials with a new preconditioner also showed an increased residence time and less energy needed to ?produce the feed. By Samuel Raymond, R&D engineer, Clextral Preconditioning systems have generally been used in feed extrusion lines (e.g. dry pet food, fish-feed) to overcome certain limitations that single-screw extruders have in terms of mixing
