Abstract

This paper presents the method for producing natural rubber powder from natural rubber latex by a spray drying process under hot gas jet generated from a pulse combustor.  The pulse combustor is valveless Helmholtz type, having single tailpipe and single air inlet.  In the experiments, the flow rate of LPG fuel was fixed at 29 l/min.  The rubber latex was sprayed from an air spray nozzle into the drying chamber.  The latex droplets were heated by hot gas jet and dried in a chamber.  The temperature of the hot gas jet in the chamber inlet was about 180 oC and the chamber outlet temperature was about 80 oC.  The latex dispersion was spray-dried to obtain rubber particles.  After the drying process, the morphology and particle size of natural rubber powders were analyzed by scanning electronic microscopy (SEM) and electron micro analyzer, respectively.  The range of particle size was from approximately 50 μm to 300 μm.

Keywords: natural rubber powder; nozzle configuration; particle size; pulse combustor; spray drying
