I was watching some fur handling videos on YouTube the other day that were put out by Alaska Fish & Game last year and there was some great information in there. One of the things that was mentioned was freeze drying your pelts after fleshing and boarding, instead of hanging them in a typical fur shed environment at a moderate temperature. They were saying there's multiple benefits to this, including the leather turning out "whiter" (obviously dependent on the species) in the final product. Because it's Alaska, I guess I'm assuming that they're talking about hanging these boarded pelts outside in freezing temperatures, but I suppose if you had a walk-in freezer and were so inclined, you could go that route as well.
I've never heard of doing this and I'm wondering if somebody can elaborate a bit - both on the benefits and if there's anything else that should be mentioned, such as leaving pelts too long and risking damage, the difference between freezing temps and REALLY freezing temps, et cetera. I tried to run a search for it here but all the results are just about freezing pelts for storage, either before or after the whole fur handling process is complete. I'm just curious what information this will turn up as this is a new concept to me. Thanks
