Abstract

"MéTODO E APARELHO PARA A FORMAçãO DE UM ARTIGO DE CELILOSE INCLUINDO UM MEIO DE RECUPERAçãO DE SOLVENTE". Trata-se da descrição de um método e de um aparelho para a formação de uma película de celulose adequada para o contato direto com alimento por precipitação a partir de uma solução de celulose, água e um solvente de celulose de óxido de amina. Depois da precipitação de uma celulose gel da solução, o gel é lavado a temperaturas cada vez mais altas e então é seco para proporcionar uma película de celulose tendo um nível de solvente de não mais do que 40ppm. Partes da água de lavagem são recolhidas e tratadas para recuperar o solvente para reutilização.
