Abstract
Las modalidades de la invención proporcionan un método para procesamiento de látex de caucho natural al usar un extrusor que incluye una pluralidad de zonas de proceso al procesar un coagulante con látex para producir un coágulo y suero. En algunas modalidades, el coagulante puede incluir un ácido, una sal de metal, o una mezcla de ambos. Algunas modalidades pueden incluir una etapa de lavado de coágulo, y una etapa de desarraigado. En algunas modalidades, el extrusor puede operarse para mover coágulo a través del extrusor para eliminar al menos alguna fracción de agua para formar un coágulo substancialmente deshidratado, y una etapa de secado para formar un coágulo seco. En algunas modalidades, puede introducirse en el extrusor un estabilizador tal como un antioxidante, y procesarse para que permanezca en alguna fracción en el coágulo seco. Algunas modalidades alternativas incluyen un método de procesamiento de látex de proporcionar un coagulante de flujo, y combinar látex con el flujo al usar una barra dispensadora de emulsión.
