Question 140
XE-GNAT2 marksNeeds review
A 12 mm thick fish fillet having 80% moisture content (wet basis) is to be frozen using a plate freezer. The plates are maintained at -35 °C. Assume the heat transfer coefficient, initial freezing temperature and latent heat of fusion are 2.0 W/m
.K, -2 °C and 330 kJ/kg, respectively. If the density and thermal conductivity of frozen fish fillet are 1050 kg/m
and 1.48 W/m·K, respectively, the time required to freeze the fillet from the initial freezing temperature is ______ h.Log in to check the answer
