can you 'recondition' an old A/C drier?

something like this....turns out you can get a replacement but for the cost of cooking it.....? If the answer is the bag rots and lets the beads go, then Ill go with that. They say the bagged desiccant can be cooked at 245F for 24 hours and then put into a tupperware to prevent it from soaking up the ambient humidity. I deal with desiccant powders and bags during work. Get the free silica sand on your hands and they dry out to the point of cracking. Not good to inhale either.
