Freeze dryers? Any suggestions or tips on purchase?

[ne kid]

Thinking of buying one or two possibly. Anyone have any experience with them? Any likes dislikes? There doesn't seem to be many brands available just thinking of upping my game from dehydrators. Just wondering if they are worth it?

You gonna go commercial?

What do you want to freeze dry?

No not commercial, unless I should. Mainly fruits a and veggies i have 2 large dehydrators going almost all the time, just thinking of stepping up my game.

I would do a single large unit first, and don't upgrade the pump to oiless, they been having problems.

Before you buy a FD though start working with mylar bags and o2 absobers.   Instead of a 2nd freeze dryer I'd get a nice vacuum chamber sealer.

Find and old brita filter pitcher, yank out the charcoal filter, and stuff TP rolled up tight in the hole, makes a great oil filter, which you need to filter the pump oil every batch or every other depending on the food.

Prefreeze everything in a -20 freezer before you freezedry, eliminates the vast majority of issues people have with foods expanding under vaccuum then drying into a hard lump - epic mess, looks like a bomb went off, but if its frozen rock hard it'll hold up better when the intense vacuum is applied.

Enough vacuum to boil cold water.

They're neat, it'll take ahwile to make it pay off.

Thanks for the response KF maybe I will wait a bit. Sounds like there could be improvements made just hope the world holds out long enough. Guess I will go back to reloading ammo, and stuffing the dehydrators.
