Abstract: | Foam Cleansing of Solid Surfaces 1. Experimental Basis In addition to the rinsing and spraying processes, mainly carried out for cleansing in food processing plants, the process of foam cleansing might gain importance, especially for the treatment of wall surfaces or the outer side of plants. Therefore, a method for testing the efficiency of foam cleansing using a model tiled wall has been developed. An aqueous dispersion of casein, according to Hammersten, and soot is used as soil which is sprayed on the tiles. The effect of cleansing is quantitatively assayed by measurement of brightness by the remission technique. Advantages, limits and accuracy of the method are discussed. |
