Limpeza CIP: remoção de resíduos de leite com baixas velocidades de escoamento de solução detergente de NaOH a 0,5% em massa

Abstract

In this work, the behavior of the process of removing milk residue adhered to the internal surface of a pipe section is studied, considering the use of low flow rates of the alkaline detergent solution formed by 0.5% w / w sodium hydroxide. The evaluation of waste removal kinetics was performed based on experimental results available in the literature. The flow velocity values were chosen based on works published in the literature, which report the use of lower flow velocities associated with the application of electrolysis in the process. The behavior of the kinetics of milk residue removal was consistent with that published in the literature, despite having significant variation between the sampled values. The flow velocity values studied did not show statistically significant differences between them in the CIP cleaning process. The results obtained show high variability in the concentration values due to the manual sampling of the process, which did not allow obtaining a more detailed representation of the removal kinetics.
