“…Where removal is considered to be affected by mass transfer, CIP processes have been successfully simulated using relatively simple devices such as the spinning disc [28,29]. More complex arrangements are required to probe the mechanisms further.…”

“…Radiotracers have also been utilized to study the rate of deposition and removal of contaminants as a function of the nature of the surface (e.g., morphology) (Pflug ef al. 1961;Peters and Calbert 1960;Perka et al 1996). Masurovsky and Jordan (1960) investigated the removal of P3' labeled bacteria from stainless steel, aluminum, glass and Teflon during ultrasonic cleaning.…”

High temperature, high pH milk processing results in the formation of mineral rich deposits that are > 70% mineral and < 30% protein by weight. This research investigates the removal of P32 labeled mixtures of calcium phosphate dihydrate (brushite, CaHPO4–2H2O) and hydroxyapatite (Ca5(PO4)3OH) from stainless steel tubes using a solid scintillation technique. Experiments were performed at pH values ranging from 2.86–7.82 and flow rates from 3.8–11.4 L/min. Previous cleaning models are reviewed and a mass transfer model is proposed which, when compared to the experimental results suggests that film removal is due to both dissolution and mechanical effects due to shear stress. A modified first order model is presented which incorporates the effects of the solvent flow rate and pH on decontamination rates. This first order model is in agreement with the experimental results over the range of pH and flow rates investigated.
