My concern with drying in the regular fridge would be that the outside would dry quickly, but leave a moist interior, which would then cause the cheese to crack.
Sorry to see you're having such a hard time with these cam's Mal. I've not made cam very often, and not for over a year, so I don't yet have any personal insights. Still, from what others are saying, I think the key is at the point you hoop them. The curds are remaining too moist and not draining properly. Perhaps try cutting your curds a bit smaller and stirr just a bit more vigorously to help expell more whey. Then, when hooping, try scooping the curds into a cheese cloth collander (one scoop), let the whey drain, then move that scoop to the hoop rather than directly ladel into the hoops. Might be worth a try anyway?
I know you'll crack this though.
