Descongelación de Bloques de Carnes por Aspersión con Agua. Predicción de Perfiles de Temperatura y Tiempos de Descongelación

Abstract

Thawing of frozen blocks by water aspersion is studied theoretically and experimentally. Measures are done over a test substance and with minced boneless meat.
The heat balance for three - dimensional heat transfer with variable thermophysical properties is solved employing explicit finite differences. Experimental determinations are performed in a specially designed model equipment, in which different operating parameters are tested.
Temperature profiles, thawing times, as well as regressions.
