Residence times of 1.0‐2.0 cm potato cubes with 0.4‐1.2% aqueous solutions of sodium carboxymethyl cellulose flowing at 453‐599 mli sec were investigated in a vertical scraped surface heat exchanger rotating at 60 160 rpm. Minimum and maximum normalized particle residence times (NPRTs) standard deviation of mean NPRTs, and characteristic parameter for tanks‐in‐series models were not significantly affected by particle concentration. Mean NPRT for 40% particle concentration was significantly higher than those of single particle ‐ 20% particle concentrations. Mean NPRTs were significantly influenced by process parameters and 2‐way interactions.
