Abstract

El método de control automático del proceso de cocción en una olla con vapor de agua bajo la tapa, es realizado sobre una placa calefactora provista de una unidad electrónica de control, siendo calculada la pendiente (DT/Dt) de la curva (1) de subida de la temperatura (T) con el tiempo (t). El valor máximo (DT/Dt max) (t) registrado es usado para estimar la carga (L) dentro de la olla, determinándose con ello un valor de temperatura de corte (Tc) idóneo para la interrupción de la potencia (W), antes de ser alcanzada la temperatura de cocción (Tn) nominal. Así no se rebasa por efecto de la inercia térmica una temperatura de seguridad (Tm), para prevenir el escape de vapor durante la cocción (ts). El valor (DT/Dt max) es usado también en el algoritmo de regulación PI de la temperatura nominal (Tn).
