In this work, the behavior of the process of removing milk residue adhered to the inner surface of a section of tube is studied, considering the use of low flow velocities of the alkaline detergent solution formed by sodium hydroxide at 0.5% m/m. The evaluation of waste removal kinetics was performed based on a mathematical model developed from a transfer function. The flow velocity values were chosen based on works published in the literature, which report the use of lower flow velocities. The behavior of the kinetics of milk residue removal was consistent with that published in the literature, despite showing significant variation between the sampled values. The flow velocity values studied did not show statistically significant differences between them in the CIP cleaning process. A sensor calibration performance indicator was proposed and tested, which proved to be suitable for future application in industrial processes.
