I just got one of these for my dog's food for when we're camping. They are such high quality that I plan to get them for flour, beans, rice, etc.

If you want a cheap way to store dry goods here is how. Remember oxygen causes food to ruin. Get some five gallon buckets with lids. You local restaurant will have several of these, as that is how their pickles are shipped. Here because of all the farmers they can’t keep them in stock, but in an urban area I am sure they would be happy to have you dispose of them. Bring them home and wash the pickle smell out of them. Put a block of dry ice in the bottom (not ice made from water duh) and place your grain, dog food or whatever you plan to store on top of the dry ice. Sit the lid down on the bucket loosely once the dry ice has completely evaporated and all the carbon dioxide has displaced the oxygen press the lid down tight. You can seal the lid with wax but they usually have a rubber seal.

This is freeze-drying made easy and cheaply. Grain like this should last 5-10 years and dog food and other things should last 2-5 years. Depending on the seal on your bucket.

I was meaning these for a good daily-weekly access to dry goods. I like the dry ice idea for long term storage however.

The seal on these things is 10x what you would find on a pickle bucket.
