A prototype cleaning map: A classification of industrial cleaning processes

Cleaning of process plant is ubiquitous in the food industry but is still poorly understood. Fouling research has benefitted from the use of a simplified classification of mechanisms. Here we review current work in food and personal product cleaning, and propose two classifications for cleaning problems, one based on soil type and one based on cleaning mechanism. The aim of the classification is both to allow results from different cleaning problems to be compared and to aid in the development of solutions that are effective across the industry.
