Abstract

The objective of this research was proposing mathematical models to predict the temperature increasing in the spherical form particles during compression on processing of the passion fruit effervescent tablet.The materials used in this research were passion fruit granule.The data of temperature increase on the materials during compression was recorded by the thermocouple.Result of the research was showed the temperature increase will be distributed by conduction to all position in the particle that can predict with the diffusion equation for dimensions three spherical coordinate.The temperature at the particle surface where friction among the contact points of the particle occurred was higher than Tg of materials of the effervescent tablet component.The particles temperature average increase during compression is 33.03 o C.
