Abstract
The invention is a process for manufacturing an iodophor filler for a lavatory cleaning cake. The process involves mixing in a dry-mixer means or "Turbulizer" a dry filler composition. The dry filler composition contains an adsorbent and the dry-mixer means provides a uniform turbulent flow of the dry filler composition as the composition passes through the dry-mixer means. The method then involves wetting the dry filler composition with a liquid iodophor while the composition is in the uniform turbulent flow. Agglomerating of the wetted filler composition then occurs within a controlled residence time of the wetted filler composition in the dry-mixer means whereby the iodophor is substantially, uniformly distributed throughout the dry filler composition. The dry filler composition, desirably, includes both a dry adsorbent and a dry absorbent. This invention includes the product of the process.
