Starch production requires the safe and hygienic conveyance of large quantities of water and starchy suspensions. Washing potatoes in particular produces a lot of sand, which can settle in shafts. HOMA agitators from the HRS series prevent deposits by continuously mixing the contents. The TPV and V pump series are available for abrasive media – equipped with free-flow impellers made of chrome-alloyed cast iron and robust seals made of silicon carbide. This combination ensures trouble-free operation and minimises downtime during processing.
