Food saving by freeze drying

   Does anyone have any experience with any type of "" freeze dryers "" like a `Harvest Right'  brand of
equipment... It looks to remove moisture in a multiple step process... Like freezing and vacuuming the
product...versus canning to preserve your food ...
    It also looks to be able to keep your product for up to 25 years with no loss... Wow, canning cannot even get close to those numbers....

I don't have any experience with the machines.  

I use my freezer to do small amounts of freeze-drying.


Here are some threads with explanations about others experiences:

Thank you for your input.....

   But when you have 4 freezers and
3 refrigerators with food in them, you try to cut your storage electric billing...

I still think going freeze dried might be the way to go....up to 25 yrs (FREEZE DRIED) vs 2 yrs ( CANNED or plain FROZEN)
  And if we have long power interruption, I then have to roll out the standby generator.... Just to keep from losing my stored food...

Again thank you,
Joe B.
   

These guys posted a video recently discussing nerdy freeze dryer math and how much energy is actually consumed per load. They were surprised and so was I.

Have you thought about a solar food dehydrator instead?
