These charts allow us to visually monitor the process for trends and out-of-control signals. For example, if the protein content consistently falls outside the predetermined upper and lower control limits, we know there’s a problem in the blending process – perhaps an inaccurate ingredient weighing, or a malfunctioning blending system – and we can investigate and correct it immediately. This proactive approach minimizes waste and maintains a consistently high-quality product.
Beyond basic control charts, I have also utilized capability analysis to assess the overall performance of the blending process and identify opportunities for improvement. We’ve used this data to make adjustments to our blending recipes and procedures to reduce variability. My experience extends to training operators on the correct usage and interpretation of SPC charts, fostering a culture of continuous improvement within the blending team.
Q 23. How would you address a situation where the final flour blend does not meet specifications?
