I just put over 150lbs of fillets in the freezer this weekend and to facilitate the fish freezing asap I had to move the fillets around in three different freezers. The process of clearing space in said freezers so I can lay the packages flat with out stacking them, then rotating fillets from one rack to the next as some racks cool the meat faster. Then once the usable space is full waiting a few hours for the fish in the freezer to mostly freeze before stacking it to add more packages to the freezer. This took quite a bit of time and in fact added about 4-6 hrs to the task of processing.
I ran into this a few weeks ago with a similar amount of halibut... the process was lengthy due to the freeze aspect.
I have also been told that putting a large mass of meat in a freezer without spacing it out will shorten the life of most home freezers. I have also noticed that the packages in the middle often take 2-3 days to freeze; which can't be good for the meat.
Are there commercial packaging shops like 10th&M that will allow you to bring the packaged fillets to them to freeze for a few hours for a fee?
Any other ideas?
