Abstract

The study of temperature distribution inside sterilizer cage was conducted previously in order to improve the heat transfer efficiency during sterilization process based on calculated heat transfer rate at various locations inside sterilizer cage. In this study, further research was conducted based on laboratory experiment to investigate the optimum condition to achieve satisfactory sterilization based on the temperature profile inside FFB and the percentage of total loose fruit per total fruitlet. The experiment was conducted at different sterilization time of 40, 50, 60 to 70 minutes excluding 5 mins deaeration period. The result suggests that the optimum heat transfer towards FFB were determined to be248kJ/kg at estimated sterilization time of 60 minutes, which corresponds to 90% of total fruitlet stripped per total fruitlet in one bunch. The result obtained was used to determine the minimum sterilization time required inside the mill sterilizer cage for satisfactory sterilization condition based on the optimum heat transfer rate obtained in this study.
