摘要

The authors present a description and results of preliminary studies on a novel spray drying method,i.e.spray drying with a simultaneous ignition of sprayed medium which is called Flame Spray Drying (FSD).Energy required to evaporate a solvent in the FSD process comes from combustion of a flammable spray component.Using this method one can dry solutions,slurries,emulsions or pastes containing a flammable solvent as well as inflammable media with the addition of a flammable substance relevant for the type and purpose of the dried product.Location of power source directly in the spray/evaporation region leads to a better use of energy and to reduced consumption of energy carriers as well as to decreased emission of harmful gases to the atmosphere.The energy carriers in the process of flame spray drying can include various types of flammable liquid components,e.g.bioethanol or vegetable oils coming from renewable energy sources.Selection of concentration of the flammable spray component has a fundamental meaning for the FSD process,therefore the effect of concentration on quality of the obtained product has been described in the paper.Studies were carried out for two materials with different thermal sensitivity,i.e.for a solution of maltodextrin and a suspension of ceramic material.It was proven that the FSD process could be an interesting alternative for the currently applied methods of drying,first of all drying of materials with low thermal sensitivity,e.g.ceramic materials.
