Long-Term Wheat and Bean Storage Tutorial

"Provident living requires us to develop proper attitudes—a willingness to forego luxuries, to avoid excess, and to fully use what we have—learning to live within our means.

Unrestricted by programs and projects, bricks and mortar, the Lord’s real storehouse is indeed in the homes and the hearts of His people. As the members of the Church follow the counsel to become self-reliant, they represent an immense pool of resources, knowledge, skills, and charity available to help one another."

Robert D. Hales, “Welfare Principles to Guide Our Lives: An Eternal Plan for the Welfare of Men’s Souls,” Ensign, May 1986, 28

For family night, Jeff and I FINALLY did something with these:

Some of the many bags of wheat, beans, rice and sugar we purchased from the Bishop's Storehouse A LONG TIME AGO!

Getting ready

So the instructions say:
1. Use approximately one ounce of dry ice per gallon (7 grams per liter) capacity of the container. Do not use dry ice in metal containers of any kind or size because of the potential for inadequate seals or excessive buildup of pressure.
2. Wear gloves when handling dry ice. (We didn't wear gloves, we just didn't touch it)
3. Wipe frost crystals from the dry ice, using a clean dry towel.

4. Place the dry ice in the center of the container bottom.

5. Pour the grain or dry beans on top of the dry ice. Fill the bucket to within one inch (25 mm) of the top.
6. Place the lid on top of the container and snap it down only about halfway around the container. The partially sealed lid will allow the carbon dioxide gas to escape from the bucket as the dry ice sublimates (changes from a solid to a gas).
7. Allow the dry ice to sublimate completely before sealing the bucket. Feel the bottom of the container to see if the dry ice is all gone. If the bottom of the container is very cold, dry ice is still present.
8. Monitor the bucket for a few minutes after sealing the lid. If the bucket or lid bulges, slightly lift the edge of the lid to relieve pressure.
9. It is normal for the lid of the bucket to pull down slightly as a result of the partial vacuum caused when carbon dioxide is absorbed into the product.

Then make sure to label it with what's inside and the date. Then remember this:
• Store plastic buckets off the floor by at least ½ inch (1.3 cm) to allow air to circulate under the bucket.
• Do not stack plastic buckets over three high. If buckets are stacked, check them periodically to ensure that the lids have not broken from the weight.

Really fascinating! I have never heard of this method. We just recently purchased 300 lbs of wheat and sealed them with "home-made" desecants (ie cut up diapers or sanitary pads). We'll have to try this next.

I was told the dry ice should go on top of the bucket as carbon dioxide is heaver than air and falls not rises. Dont know if it correct tho.
