The shelf heaters can be set to automatically control the rate of sublimation during the primary drying cycle.

The food and pharmaceutical industries crucially rely on freeze drying for the long-term storage of products. This method enables businesses to preserve product quality, extend shelf life, and improve stability.

The best choice I ever made when it comes to long-term storage food is getting a freeze dryer. I didn’t always think that. It was far more work than I imagined and the maintenance on the machine is annoying when it needs it.

One of the reasons I like the small freeze dryer is the size. At the same time, my large freeze dryer takes up space equivalent to a clothes dryer—the small one doesn't.

When my son goes to college in a few months, we will send him with many freeze dried meals and continue to mail them to him as needed. Most colleges don’t have safe gluten-free options, and while in an ideal world my son would be able to cook all his own food, I know that’s not practical or likely. Freeze dried meals on hand are an easy way to keep from being cross contaminated at the cafeteria!

Of course the bags were frozen right in to the mass of berries so it was quite a painful struggle to get the mess to the point where I could hack off slices of the berries to put on the trays.

Hopefully I said that in a way that makes sense! As well, does it matter which port is used as "in" and which as "out"?

The system records and maintains a log of the pressure and temperature during all parts of the freeze-dry cycle.

A bit of background on me - I used to work in a sold state fabrication lab (university research lab) and had a lot of hands-on work with ultra-high vacuum equipment. The pumping we do for freeze drying was what was required to just start

- Cost-Effective: While the initial investment can be high, freeze drying at home can save money in the long run by allowing you to preserve leftovers and bulk purchases.

The only downside is that the interior is now so cold that defrost time has doubled! I Buy Now use a large high volume fan to defrost the unit, not the heat trays. It used to be a 15 minute job, now it is closer to 30 minutes.

4 trays of corn takes only 16 hours, I would estimate that we have cut our FD times by 30% or more! Condensation has been decreased by 90% - pelo more dripping down the interior front panel and collecting on the aluminum base. There is still condensation around the front door seal, but it pelo longer drips down the front onto the floor.

Why? Because many of the meals we cook are intended to be eaten now AND freeze-dried to store away for the long haul. We don’t do it for chicken finger night but by golly we do it whenever she makes her freeze-dryer-appropriate meals like beef stroganoff.

Freeze dried Skittles are a favorite in my family. They end up with a crunchy texture. Other candies have a crunchy exterior and an airy interior.
