Laura McDonough says: 2 years ago We bought one around the Y2K crises which never happened, ended up using it some, then selling it. I will not clutter up my place with useless crap of all kinds in the future, me and friends said (been there done that).
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.
Looking at the picture you can see the water drops on the insulation and where the water had flowed down the back of the front panel.
What type of oil does the vacuum pump use? Harvest Right freeze dryers use food-grade vacuum pump oil, which is available for purchase. One gallon typically lasts several months with proper filtering and maintenance.

I've also added an oil catch can that does a wonderful job of trapping oil vapor exiting the exhaust of the pump. Now instead of coating the area in a fine oil mist, the oil settles into the can. The clear tube on the side Buy Now of the can lets you know how full the can is.
What I presume was happening was that condensation was building up on the cooling coils between the insulation and the chamber and freezing. When I finally turned the FDer off it took 3 days for the ice buildup to melt and slowly soak through the insulation and drip onto the counter.
And therein lies the cons to buying a freeze dryer. It takes time to make them cost effective. Depending on humidity in your area, a single run can take up to two days to complete.
Furthermore, the modern freeze dryer systems have vacuum pumps and refrigerators which enhances the drying cycles and saves energy.
Never allowing the unit to heat up to ambient temps - Quickly removing the ice from the chamber and starting the next cycle while the chamber unit is still very cold.
Karla Abreu says: 2 years ago I just think pressure canning is the easiest way to preserve food and know it is totally sterile. And it is relatively easy
Forgive me for the extremely long post but I thought other southerners may also face this problem and could use this information.
I, too, have noticed a significant difference when I defrost mid-cycle. I do that routinely now. I carefully use a heat gun to "shock" the surface of the ice, moving back and forth across it fairly swiftly, which causes it to crack and separate somewhat from the cylinder.
