摘要: Cleaning-in-place (CIP) of pink guava puree (PGP) fouling deposits is not well known compared to dairy which established. Lab-scale cleaning test rig has been used investigate the performance PGP deposits. Removal mechanism during alkaline-based were investigated using NaOH concentrations (1.0 wt% -2.0 wt%), temperatures (35 - 70 °C) and fluid velocities (0.6-1.5m/s) over a range Reynolds number (Re= 4x104 1.8x105). Cleaning rate was quantified by measuring remaining area at sample holder every 1 min. The efficient CIP process for deposit can be obtained 1.5m/s, °C, with concentration 2.0wt%).
