Abstract

MÉTODO PARA PROCESSAR POLPA, SISTEMA PARA CONTROLAR UM APARELHO PARA LAVAR E REMOVER ÁGUA DA POLPA, APARELHO PARA LAVAR E REMOVER ÁGUA DA POLPA, E, INSTALAÇÃO PARA PROCESSAR POLPA. Um método para processar polpa em um aparelho para lavar e remover água da polpa, e um sistema para controlar este aparelho, o aparelho compreendendo dois rolos de pressão rotativos (102, 104) tendo uma superfície externa permeável (106, 108), os rolos de pressão (102, 104) definindo um espaço entre rolos de pressão (112) entre eles, em que espaço entre rolos de pressão (112) a polpa é prensada, pelo menos um dos rolos de pressão (102, 104) sendo móvel em relação ao outro rolo de pressão (102, 104) para variar o espaço entre rolos de pressão, e o processamento da polpa no aparelho é determinado por um conjunto de parâmetros de operação variáveis durante operação, a distância entre os rolos de pressão (102, 104) sendo incluída em dito ajuste; pelo menos um valor desejado para um parâmetro de controle específico é ajustado, o parâmetro de controle específico sendo incluído em um grupo de parâmetros de controle; o parâmetro de controle específico é medido; e pelo menos dois dos parâmetros de operação variáveis de dito conjunto são ajustados durante operação, onde a distância entre os rolos de pressão (102, 104) é um de ditos pelo menos dois parâmetros de operação variáveis, para manter a diferença entre o valor desejado ajustado e o valor do parâmetro de controle específico medido abaixo de um certo nível.
