Hi all,
I found a reuseable food grade vacuum seal bags! It comes in huge size, to be use for rice, beans, and so on. The bags has a valve of some sort on it that has to be closed to prevent air to get in the bag.
It came with a pump. I have vacuumed whole wheels of 10 gal each, and it still have plenty of space for bigger wheels. It has been a week and the bags is still fully vacuumed.
I am not sure with the "reuseable" part though, how one suppose to sanitise these bags?
