A breakfast cereal processing line involves several key steps: First, grains are received, cleaned, and stored. They are then milled into flour, which undergoes cooking and extrusion to create shapes. After cooking, moisture is removed through drying, and products may be toasted for added flavor. Coating machines apply flavors and coatings, followed by cooling to ensure the right texture. The finished products are packaged, sealed, and labeled for distribution. Throughout the process, quality control measures ensure safety and consistency, and final products are stored before being shipped to retailers or consumers.
