Abstract

The purpose of a developing a reliable and accurate spreadsheet modeling tools was in order to investigate heat transfer efficiency inside mill sterilizer cage by predicting the temperature profile inside FFB at various locations inside the cage. The model was previously validated based on Mongana Report, Chan SY and Ang et al suggested that the model was best predicted by the experimental data which was taken from experimentally determined data of Ang et al, based on 15kg bunch at sterilization time of 1 hour (3600s) with the thermocouple inserted into a hole drilled near or beside stalk. In this study, an experiment was conducted to investigate the temperature profile inside FFB based on different FFB weights (12kg, 15kg and 18kg) by using temperature sensor probe inserted into a drilled hole beside FFB stalk and inside the stalk. The result suggest that temperature profile located at near or beside the stalk was best represented as the temperature profile located at the center of FFB as per validated result with Ang et al, with the smallest percentage error in the range of 0.31-5.82% for all FFB weight (12kg, 15kg and 18kg).
