Stay Fresh Freeze Dryer with Industrial Pump

One great machine !!!

We have been freeze drying now for a few months and are starting to really get a quantity of food put up. We have not had any problems with this Stay Fresh machine or the industrial pump. We are very happy with it as well as our JVR110 chamber vacuum sealer. I don't have anything to compare it to as this is the only freeze dryer I've ever owned but from what I see on posts in the groups I follow I am so thankful I bought this make and the 4 tray medium is very adequate for the needs of two people and still make enough that we can make some packages for family and friends. We basically consider ourselves as hobbyists at this point. We don't do candy and don't have a freeze dry business. This is for fun and food security and to save some money as he prices of food keep rising.

What fun!

My family thought I was nuts when I told them what I was buying....let me tell you that it is certainly making Christmas presents fun this year. While I think you learn as you go.....I love to cook and this is just an extension of the kitchen for me now. Thanks for a great piece of equipment.

Love the machine - trays could be improved

My StayFresh Freeze Dryer has been running almost nonstop since it arrived. I love how quiet the vacuum pump is. My one gripe is the tray edges. The edges are sharp and cut my fingers a few times. I've eased the edges with a file and resolved the issue quickly. I'd like to see about extending the vacuum hose about a foot so I could place the pump on the shelf below the freeze dryer. One thing I'd like to see if it's possible is to make the numbers larger on the display screen. I have a hard time trying to read if the freezer has reached a negative temperature without having to go find some reading glasses. An absolutely amazing machine hands down! I would choose StayFresh over any other option.
