Abstract

METODO PARA MEJORAR EL BRILLO DE LA PASTA DE MADERA, QUE UTILIZA UNA COMBINACION DE UNA CARGA DISTRIBUIDA DE LICOR COMPLETAMENTE BLANCO, DURANTE LAS ETAPAS DE LLENADO EN TEMPLADO, EN CALIENTE Y DE COCCION DE UN PROCESO DE HORNEADO Y TEMPERATURAS BAJAS DE COCCION, DURANTE LA ETAPA DE COCCION. LA CARGA ALTA TOTAL DE LICOR BLANCO, ESTA ENTRE 15% AA - 35% AA, MIENTRAS QUE LA TEMPERATURA DE COCCION VA DE 150 - 168 .METHOD TO IMPROVE THE BRIGHTNESS OF THE WOOD PASTE, WHICH USES A COMBINATION OF A DISTRIBUTED CHARGE OF COMPLETELY WHITE LIQUOR, DURING THE STAGES OF FILLING IN TEMPERATURE, HOT AND LOW TEMPERATURE BAKING AND TEMPERATURE PROCESSING COOKING STAGE. THE TOTAL HIGH LOAD OF WHITE LIQUOR IS BETWEEN 15% AA - 35% AA, WHILE THE COOKING TEMPERATURE IS 150 - 168.
