Challenge Sanitarium aimed to improve the consistency and quality of Weetbix by refining the wheat grain drying process. Variability in parameters such as temperature, humidity, and airflow were affecting grain properties and, in turn, the final product. The company needed a clearer understanding of which factors most significantly influenced grain quality to enable better control and potentially improve dryer design.
Solution A targeted study was conducted to analyse how key drying parameters impacted the physical and functional attributes of wheat grains. Data from various dryer models and operating conditions were examined using experimental trials and statistical modelling. The analysis revealed optimal parameter ranges and offered actionable insights for both process improvements and equipment enhancements.
Impact The findings contributed to Sanitarium improving product quality, reducing variability, and enhancing production efficiency. By controlling critical drying factors, the company can ensure more consistent grain performance, optimise energy use, and inform future upgrades to dryer systems. In addition, the results have prompted further modelling research, supporting ongoing innovation and refinement of processing technologies.
