In any sector – whether biotech, food production, or pharma – adopting high-capacity freeze dryers helps improve efficiency and business sustainability while meeting regulatory obligations.

Finding used freeze dryers isn't easy. That's because most people who get them consider them a long-term investment. As such, they hold on to them for years. However, a used freeze dryer or two sometimes makes its way onto the market.

We’ve bought six so far with two more on the way. But families and individuals considering getting their own can and should as long as they go in with their eyes open.

I have one of those hand held heat guns (inexpensive from HF), but I was afraid of accidently burning the insulation. My gun gets very hot! I do the same technique with a fan, shock the ice and listen for the cracks as it separates from the chamber wall.

It freezes the product and lowers pressure to remove ice by sublimation. Sublimation is the transition of a substance directly from the solid to the gas phase without passing through the liquid phase.

Upon turning off the pump (no isolation valve on the pump - standard setup), the chamber pressure rose quite rapidly going to 2000 mTorr and continuing up in a couple of minutes or so.

Automatically adjusts settings for optimal vacuum pressure and temperature, ensuring the best preservation of your materials.

After buying our freeze dryer I was naturally curious as to how it "knew" when something was done, since batch times varied so much depending on what was being processed. Watching the cycle times didn't seem to tell me anything at first -- especially without a thermometer to tell me what was happening inside -- until I finally caught on that applying heat to the frozen food affected the vacuum, which provided the measure of how dry the food had become.

Drying things out played a roll as well as the added insulation. We had 3.5 weeks of constant rain here in central NC with humidity over 95% and temps near 95F in the beginning and tapering down to 80F by the end of the rain. The condensation on the front panel around the seal had water running down the front of the Freeze Dryer constantly during the entire cycle, not just the freeze cycle. I initially went into the FDer to simply stop the humdity from reaching the outer chamber shell and freezing.

adding insulation on the 3 ports on the chamber (One time thing - the drain and vacuum ports are very easy to get to)

As a bonus, freeze-dried products are lightweight making them desirable for outdoor activities, emergency kits, and even space missions. Food manufacturers looking to broaden their offerings find freeze-drying prepackaged food as an enticing option because of the increased safety of food and reduced waste.

Granted, most of that time is the freeze dryer doing all the work, but the process is not without effort. Once the food is Buy Now ready it must be put into appropriate containers with oxygen absorbers and sealed properly so they can last.

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 Buy Now her freeze-dryer-appropriate meals like beef stroganoff.
