Spray bars can be an effective method of applying an antimicrobial in your process, but only if you achieve adequate coverage.
Additionally, they are an important preventative control in your FSMA Food Safety Plan. If not working correctly, they can result in costly corrective actions or even a recall. When evaluating your spray bar nozzles for coverage its important to determine what spray pattern you are trying to achieve. Ideally you want the spray pattern to overlap to ensure no product is being missed. While there are many spray pattern options, both Figure 1 and Figure 2 represent options that will ensure full coverage.
