Dear List,
A colleague has encountered a situation that has me puzzled and I hope
someone can provide an answer.
They are a pet food manufacture and have a some pallets of frozen ground cod
frames. The frames are stored at 0 degrees F (-18 degrees C). The frames
are in plate frozen blocks and the bottom rows of the pallets have become soft
and are oozing an amber colored liquid with roughly the viscosity of water.
The bottom blocks are easily penetrated by a temperature probe, so are not
hard frozen at all.
They have contacted the supplier, who has told them they freeze the blocks
to a minus 30 degrees F before they are pulled from the plate freezer. They
have no ideas about what is going on
Any thoughts?
Sincerely,
John Clemence
