01%, effectively preserve these packaged foods without the need for preservatives or additives and without the need for vacuum sealing.
The entire process is automated using highly intelligent built-in sensors that know exactly when the food is properly freeze dried. Just press start and the freeze dryer will beep when finished.
Long ago. and B. I don't have the test equipment I did then. I guess what I'm saying is don't be afraid to get too technical with me in your answers. What I wouldn't give for a helium leak detector right now...
Gleaming, inviting, New Age—the siren call to Americans who love their gadgets. But is a home freeze-dryer the appliance for you? Here is some information designed to cut through the advertising hype and provide a voice of reason on the pros and cons of home freeze-dryer ownership. The Science Behind Freeze Drying
We have two freezers in the garage as well. All of these machines generate heat and humidity. Our FDer front regularly sweats up an storm and water drips off the door and from around the entire chamber perimeter down the front of the unit. It got so bad that I taped a plastic shield above the display to route the water around it. You can see the water on the door and on the stainless steel front past the 4 screws on the unit.

A walk-in freezer isn’t an appliance that you would find in a domestic kitchen! But, they’re very common in restaurants.
Obviously things like ice cream and marshmallows you would want to let the freeze cycle run longer. When I'm ready to start the drying cycle, I open the door, remove the insulator, and check the temperature of the food on the trays with an infrared thermometer. As long as it's below -10F I start the dry cycle. A side note for TonyC, have you ever thought about attaching a mirror to each side of the tray rack to reflect the radiant heat back in to the trays? I've looked at some mirror finish stainless on ebay, and it looks like you could do it for about $quarenta. Not sure if it's worth a try or not. I would think it would let you get more water out in a cycle because the radiant heat wouldn't be warming the ice on the chamber walls. Just a thought....
