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).
Furthermore, the development of vacuum drying and the control of temperature rise have increased the efficiency of the freeze-drying systems which leads to reduced cycle times and lower costs. The development of the industry gives a lot of hope for the future of freeze drying in both the pharmaceutical and food industry.
My husband has been contemplating cost effective alternative ways to get oil-less vacuum happening... what would the specs needed be, since I don't have a pump to look at. Hopefully I asked that in a way that makes sense.
Many times, you can still freeze dry something if you mix it in. For instance, if there’s a meal that has butter in it, it’s fine to freeze dry. It may just reduce the shelf life a little. So instead of 25 year shelf life, it might have a 10 year shelf life.
•Control of the amount of time a material is held at the ultimate freeze temperature before the drying cycle is started.
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.
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 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.
In addition, the casing stayed in a Secure managing temperature during our lab examination, even on the best placing.
12 Posted September 16, 2015 You've given me website an idea. I have the parts at the shop to use an actual filter head and a spin on filter. I could have a bracket laser cut and powder-coated that would hold the filter/head assembly horizontal which would allow it to completely drain and the outside of the filter would stay clean.
In times of crisis or natural disasters, having a stash of freeze-dried meals can be a lifesaver. Your family's safety and well-being are priceless. Not only does a freeze dryer set you up to survive, it lets you control the quality and content of your Buy Now emergency food supply.

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.
