Why are dried bread crumbs passed through a tamis after processing?

Dried bread crumbs are passed through a tamis to ensure a uniform texture and consistency by removing larger or uneven particles. This process enhances the quality of the breadcrumbs, making them finer and more suitable for various culinary applications, such as breading or thickening. Additionally, using a tamis can help eliminate any unwanted clumps, resulting in a smoother product. Overall, this step contributes to the overall performance and appearance of the breadcrumbs in recipes.
