Jifeng Yang successfully defended his PhD thesis at DTU on 1 April 2019.
Cleaning-in-place (CIP) is a widely used technique in food and pharmaceutical industries. The execution of CIP is critical for food safety and public health. Since the introduction of CIP, various studies have been performed in order to reduce the cleaning costs without compromising the cleaning quality. The starting point for the thesis was a mapping study at the world-leading brewery, Carlsberg Danmark A/S (Fredericia), in which the most time- and resource-consuming CIP operations were identified. The suggestions for improving the existing CIP systems in the brewery are representative for the processes where similar CIP systems are utilized in other fields. The findings from the mapping study led to the topics explored in the Ph.D study.
