Query: not in Vermont

I've tried this unit for two winters in Vermont. The compost just sits in there and freezes to a solid mass. In spring I still have all the garbage, and it is impossible to get the soggy gook out of the small opening. I do use leaves and kitchen wastes, as well as the enzymes sold to go with the unit. Am I missing something?
