Abstract

Patente de Invenção: <B>"PROCESSO PARA A PREPARAçãO DE DERIVADOS DE CELULOSE HIDROSSOLúVEIS EM FORMA DE Pó"<D>. A invenção refere-se a um novo processo, particularmente económico, para a preparação de derivados de celulose hidrossolúveis em forma de pó. O processo engloba o intumescimento ou a dissolução do derivado de celulose em água e a subsequente secagem por moagem do derivado de celulose intumescido ou dissolvido em um moinho por impacto com separação por corrente de ar de alta rotação sem peneira por meio de um gás de arraste quente e gás de transporte. A secagem por moagem e os produtos são influenciados pelo ajuste de uma fração de água definida no derivado de celulose intumescido ou dissolvido.
