Abstract

Patente de Invenção: <B>"PROCESSO PARA A PREPARAçãO DE DERIVADOS DE CELULOSE HIDROSSOLúVEIS PULVERULENTOS COM APLICAçãO DE UMA MISTURA DE VAPOR DE áGUA/GáS INERTE OU MISTURA DE VAPOR DE áGUA/AR COMO TRANSPORTE E GáS PORTADOR DE CALOR"<D>. A invenção refere-se a um novo processo particularmente económico para a preparação de derivados de celulose hidrossolúveis pulverulentos. O processo abrange o intumescimento ou a solução do derivado de celulose em água e a secagem por moagem seguinte do derivado de celulose intumescido ou dissolvido em um moinho de choque de corrente gasosa com alta velocidade sem peneira em que se utiliza como transporte e gás portador de calor uma mistura de vapor de água/gás inerte ou uma mistura de vapor de água/ar.
