I have seen that removing the frozen items out of the trays in plate freezer is a very tough task.

I have seen variety of tray materials, but still to find a better ways.

Our forum members must have an idea on this issue.

This is applicable for all the stuff like Chicken, fish items & almost all the places I have seen.

so in short to avoid this problem,

what is the tray system being used, any special mechanism to remove the frozen blocks, ( it is all manual operations)
We have seen infrared heating system , mechnical pistons systems etc, but not a single one one working satisfactory
