Abstract

"DISPOSITIVO DE PULVERIZAçãO PARA GRANULAçãO POR FUSãO EM LEITO FLUIDIZADO, MéTODO PARA A PREPARAçãO DE GRáNULOS SóLIDOS E USO DE UM DISPOSITIVO PULVERIZADOR". A invenção trata de um dispositivo pulverizador para a granulação por fusão em um leito fluidizado que compreende um bocal (2) com um canal de alimentação para um líquido a ser atomizado, onde o líquido é conduzido através de dispositivos emulsificantes e para o interior de uma camara de mistura interna para gás e líquido, antes de ser alimentado ao leito fluidizado. O bocal tem um canal separado para o gás atomizador montado concentricamente em torno do canal central de alimentação de líquido para o líquido a ser atomizado ou nebulizado. A câmara de mistura circunda a zona de saída da pulverização líquida dos dispositivos emulsificantes e o gás, permitindo eficiente misturamento de gás de atomização e líquido de alta velocidade e tendo um tampo de gás externo (1) onde gás de fluidificação é canalizado para o interior de um bocal acima do dispositivo pulverizador.
