Dry Dog food storage? Long term

[Tim-g19]

I have to say Ive seen so many good or great idea's here from you other Hoosiers. I really respect your opinions and idea's

So heres the deal. Have a 2yr old Yankee Terrier, He has ALOT of food allergies though, Chicken, Wheat, Corn, Barley. theres 29 total things he is Highly allergic too. Luckily Venison and Rice are not so I have that to fall back on. BTW, try to go and find a dog food w/o Chicken , wheat , or corn in it. It was so fun standing reading ingredients for hours only finding 2 that are stocked by south side pet stores, and not have to be special made or mail ordered.

Anyhow we have some now and I was wondering if anyone had any idea's of how to vacuum seal or store say 100lbs or more of it, Not all together.

Ive never Freeze dried or vacuum sealed anything, Would you need to do much to dry food? to prep for storage?
And how about opinions on machines to do either?

Thanks in advance for help on this

Yankee Terrier is on all his paperwork and Vet and Microchip stuff, but its just another less known name for a Pit Bull.
