How I Vacuum Seal Pack Cornmeal and Flour 

By heat treat I mean in a oven at a low temperature for so many minutes the let cool completely before bagging and sealing.

Well I just vacuum mine in a paper bad inside my seal bags .

@@paulatudor691 you know to watch for bloating of the bag right, it's not a good sign. One of my friends thought if you vaccuum seal something it was good for ever, which is not the case.

@@lindaschmidt981 no never has it . Usually gases cause that . Mine are hard as a 18 year old. So I never had a bag puff back out . Knock on wood.

@@lindaschmidt981might wanna open it the heat treat method tends to introduce moisture to the product

I did a repurpose on it. Found it on ebay. There are a lot of sizes -----> --www.ebay.com/itm/3-Gallon-250mm-9-8-Stainless-Steel-Vacuum-Degassing-Chamber-PC-Lid-from-USA/174799472337?&shqty=1&isGTR=1#shId--

That web site doesn't exist anymore.@@N7JFP

Yes they are very quick and works perfectly every time!!

Great Question. I don't know. I am using flour two years old. No problems yet.

Thanks for being interested in vacuum sealing. Do an Amazon search for "3 gallon vacuum chamber stainless steel". There are a lot of sizes to choose from. Also on eBay. Also watch sealing walnuts and oatmeal. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-QC05deRz3iE.html ... Hope this helps. Larry

I have no data/study that shows how long you can seal flour/cornmeal and it is still good. I would use it up in a year or two to be on the safe side. Main concern is protection from creepy crawly bugs. Thanks for watching. Larry

You can find the oxygen remover packets on Amazon for 10-15.00 per hundred. I don't use them. Thanks for watching. Larry

@@N7JFP thank you

Thanks for watching. Great question. I do put the flour/cornmeal in the freezer for 3-4 days then remove it and let it come to room temperature for a day or two before I vacuum pack it. Suppose to kill any bugs or eggs. Larry

@@N7JFP Do you have a specific reason why you do it prior to vacuum seal it? Due to moister I would do it after vacuum sealing it - but it might not work in glas. In a plastic bag it works fine.

@@michlblacksmith I read somewhere it was best to use the freeze method to kill possible bug/eggs infestations in grains before storing them. I do let them sit for days to let any moisture evaporate. I try to cycle thru the ground grains within a year. I have no long term storage data. Larry

I assume you mean the video. Video camera and edited video with Camtasia for windows. Thanks for watching.

I decided not to use oxygen absorbers and just check the seal every so often. -25 inHg makes a very tight seal. One year is a long term storage for me. Thanks for watching. Larry
