Vacuum sealing a 25 pound bag of grain; or any material. (Part 1)

How to vacuum seal a 5 gallon Mylar bag for long term storage using a large vacuum chamber made from a repurposed water pressure tank. This process allows yo to place a Mylar bag in a vacuum and reduce the oxygen content for long term food preservation. The bag is positioned in a 5 gal bucket to give it some shape and is easily removed to allow heat sealing the corner you cut off that allows the air to be vacuumed out. It works on smaller bags also as long as you can have enough material to seal and act as a check valve once the vacuum is removed. It sometimes takes more than one try to get the bag to seal.
