You obviously need an area that you can quickly and easily return the dried coal to a transport bucket, or whatever you load with. It will need to be able to be kept warm, and need a place to collect water from the damp coal. If you want to use a 4 by 4 area, that handles 200 lbs well, or a full 4 by 8 area will do double that amount. You will have trouble with screening to hold that much weight and if you can get by with just an exposure time , then you are good to go. Out of the bags is the best solution, and into a heated space. Many bagged guys simply bring a supply in near the boiler or furnace, however that isn't cool if you are doing it in the living room. Get it into a heated area, open the top of the bags, spread it out if necessary.
Try to keep a few days ahead and you will have no issue.
