Summary

Recently, several manufacturers of domestic refrigerators have introduced models with "quick thaw" and "quick freeze" capabilities. In this study, the time required for freezing and thawing different meat products was determined for five different models of household refrigerators. Two refrigerators had "quick thaw" compartments and three refrigerators had "quick freeze" capabilities. It was found that some refrigerator models froze and thawed foods significantly faster than others (P<0.05). The refrigerators with the fastest freezing and thawing times were found to be those with "quick thaw" and "quick freeze" capabilities. Heat transfer coefficients ranged from 8 to 15 Wm-2K-1 during freezing, and the overall heat transfer coefficients ranged from 5 to 7 Wm-2 K-1 during thawing. Mathematical predictions for freezing and thawing time in the refrigerators gave results similar to those obtained in experiments. With the results described, manufacturers can improve their design of refrigerators with quick thawing and freezing functions.
