ISSUE FOCUS 36 FEED & ADDITIVE MAGAZINE April 2024 to a feed with 47% starch content. Starch gelatinisation was measured using a Differential Scanning Calorimeter. As shown in graph 2 and 3, SmartMoisture® delivered improvements in both the percentage of gelatinised starch in feed and the gelatinisation rate of starch. In improving starch gelatinisation, we are able to: • Improve pellet quality (PDI) • Reduce fines/dustiness of feed • Increase glucose absorption in the small intestine MAXIMISING ENERGY SAVINGS AND INCREASING THROUGHPUT Glycerol esters of propionic acid and surfactants have given consistent results in terms of reducing energy usage and/or increasing the throughput as you can see from graph 4 and 5 below. In doing so, operational costs are reduced, improving the profitability of the mills implementing SmartMoisture®. SERVICE LEVEL APPROACH Supplying moisture management solutions is not a drop and go product. This product needs to be supported by various specialists to ensure maximum benefit. A variety of conditioning, pelleting and cooling setting needs to be considered and adjusted to ensure optimal milling efficiencies. Devenish offers feed milling support through various feed milling specialists within our team across the globe. CONCLUSION Moisture management has become an important part of every feed mill strategy in reducing cost by managing losses and driving more sustainable factories. Our results to date show that improvements can be made across numerous parameters with on-going research continuing to deliver further performance benefits.
