Fouling deposit analysis of heat-induced pink guava puree

Fouling deposit phenomena are common in industrial heat exchangers. It can accumulate during heat treatment and cooling process. The objectives of this work were to investigate the characteristics of pink guava puree (PGP) fouling deposit and to predict the effect of fouling deposit on tubular heat exchanger. The similarities of fresh and commercial PGP were investigated prior to fouling study. The properties (pH, total soluble solid, thermal conductivity, specific heat capacity, composition and rheology) of both purees were compared to determine the suitability of the commercial PGP as PGP fouling fluid model. Most properties of both purees behave similarly except for pH, total soluble solid (TSS) and rheology properties. There is a significant different for the pH and TSS for both puree (P
