Abstract

"USO DE DETECTOR DE LINHA óTICO, MéTODO PARA A REGULAGEM DE UMA COLUNA DE LAVAGEM EM UM PROCESSO DE CRISTALIZAçãO EM FUSãO, E, APARELHO PARA SEPARAR CRISTAIS DO LìQUIDO MãE EM UM PROCESSO DE CRISTALIZAçãO EM SUSPENSãO". A invenção está relacionada ao uso de um detector de linha ótico para a regulagem da posição da frente de lavagem e/ou da frente estrutural que dizem respeito ao leito de cristais de uma coluna de lavagem durante um processo de cristalização em fusão, bem como a um método correspondente para essa regulagem. O detector de linha, como por exemplo uma câmara CCD ou um arranjo linear de sondas de luminescência, fica disposto de tal modo que as propriedades óticas do leito de cristais podem ser continuamente detectadas em uma região que corre paralela ao eixo longitudinal da coluna de lavagem. A dita região cobre a posição nominal desejada da frente de lavagem ou da frente estrutural.
