microbial contamination impacting feed safety. Temperatures which are too low reduce the microbial log reductions, and feed safety is at risk. Feed safety is a core value in the millSMART programme, ensuring either the antimicrobial Sal CURB or the mould inhibitor Myco CURB in the Opti CURB dispersing solution is added which kills upon contact, additionally works in synergy with heat treatment to reach microbial kill-off. The pellets enter the cooler, with the objective to effectively
cool the pellet. Heat in the pellets is lost due to both evaporation and convection, through the manipulation of both the air fan speed and pellet cooler retention time. If cooling is done too quickly or ineffectively, an unstable poor-quality pellet remains, with the risk of condensation and microbial re-contamination. If pellets are left too long in the cooler, over cooling results in over drying which is costly when considering feed inventories and feed yield output. millSMART is a tool to effectively manage cooling practices to ensure a cool pellet with a targeted moisture content achieved. Standardising feed processing is a challenge, due to the impact
of many variables affecting the productivity and quality of feed produced. To fully understand the effects, it is important to trace a produced batch of feed, from the initial reception of all the raw materials used to produce that batch of feed through to final loading and storage of the finished pelleted feed. Variables impacting feed processing are specific to the location in feed processing. Identifying
and accurately measuring all these variables is the first step to understand their impact on feed processing for what millSMART is a useful support. Process targets and key performance indicators are set with
millSMART to ensure feed quality is reached during processing. The quality is essentially how much variation there is around that target or specification. In other words, reducing process variation is a measure of quality in a feed operation. This can be evaluated starting at raw materials intake, however interventions applied at other steps such as in the mixer are more commonly seen. In principle, the sooner efforts are made to reduce variation in the process, the more the optimised effect will be carried through during subsequent steps in feed processing. Process variation is minimised within a batch of feed. The variation between subsequent batches of feed produced is managed with process automation technologies such as seen in the millSMART online programme,. Large process fluctuations are eliminated, reducing variability and improving quality of process operations and pellets. millSMART online provides key
benefits and insights for effective feed processing, contributing to the sustainable development of feed operations and environmental protection for a happier, more prosperous and healthier world.
