The assessment of cleaning procedures contributes significantly to ensuring hygienic production. To study the cleaning of starch and protein from stainless steel coupons under varying process conditions, a continuous flow cell has been used. It was possible to monitor the removal of dried soil films, and to determine the effects of flow rate and temperature of the cleaning fluid on cleaning rate. A comparison of the cleaning behavior of whey protein, soy protein, pregelatinized potato starch or corn starch revealed that the cleaning efficiency largely depends on soil type. The results indicate that specific physicochemical properties of a polymer have to be considered in the classification of cleaning mechanisms.
