The Andritz OptiMix paddle mixer for feed compounds is a high-speed mixer that mixes up to 30 batches per hour. The rotor changes direction between each batch, ensuring that all surfaces are kept clean by the material being mixed. Furthermore, placing the nozzles directly in the inlet ensures that they are wiped clean as well while each batch is loaded. The paddle mixer was tested and verified by TI (Technological Institute) and MTSE (Micro Tracer Services Europe) and achieved the highest scores possible for mixing quality (mixing probability of > 25 percent within 75 seconds, equivalent to a coefficient of variation of < 5 percent).
