Figure 2. Time for Frozen Food in Freezer to Thaw after Current Shut-off. 

 (Half a freezer load, 150 pounds frozen apples.) 



Since food showed no signs of spoilage at the end of eight days when the freezing 

 unit was completely filled, and none at five days when it was half full, and since 

 during this time the temperature was within the range used for the refrigeration 

 of foods, it would appear that the average power shut-off would not be too serious 

 with this type of home freezing cabinet. As a general rule, a power or mechanical 

 failure could be remedied within a safe length of time.
