I forgot to say that I dry mine in the open vials overnight, BUT I lay them under the lamp on top of my computer table out of reach for the cats to play with. The lamp stays on a lot. I also have a fan going all the time right beside the computer table. So there is circulating air to dry them in the vials. In the morning I close them and freeze. It's just too too much work to transfer them from one place to another.
If I only have a couple or very few vials to use I will put them in my pocket, my apron or hold them in my hand until they thaw. In the late spring this is only a few minutes. As long as the pollen is nice and dry you can refreeze it. I one time had Grace Stamile tell me about a little lady friend of hers who took her pollen out of the freezer each day then refroze it. I said, she takes it out every day then refreezes it? She said yes and laughed. The method she and Pat used was putting fresh flowers in the fridge over night then using them in the morning. They had a special fridge just for the flowers in the greenhouse.
