How loud is the freeze dryer pump? The pump operates at about 65-75 decibels, similar to a normal conversation or dishwasher. Many customers place their freeze dryer in a garage or separate room for quieter operation.
5) Next up I insulated the pipes where condensation forms directly from the compressor. I used inexpensive water pipe insulation from copyright or Home Depot to wrap all exposed parts that had potential for condensation.
Granted, most of that time is the freeze dryer doing all the work, but the process is not without effort. Once the food is ready it must be put into appropriate containers with oxygen absorbers and sealed properly so they can last.
After it’s processed, I weigh the tray again and subtract the ending weight from the beginning weight. That tells me how much water to add for reconstitution. I like to write on the mylar bag or jar lid how much water to add so I don’t have to guess when I am ready to reconstitute the food.
By this point, most of my son’s friends know about his dietary restrictions and it doesn’t bother them. My son takes rehydrated freeze dried meals to school banquets and to other social gatherings.

I remember reading somewhere in this thread where somebody was asking how long you run the freeze cycle with pre-frozen food. I have my chest freezer set to -12F, and I usually let the freeze dryer cool more info for an hour before I put the frozen food in. After I load the food in I wait another half hour to start the drying process. I've had a lot of cycles that the total time between pulling one batch out and starting the drying cycle on the next is around 2 hours. I'm running mine in a cold garage, so it cools down pretty quickly. If you have yours in a warm room it would probably take a little longer.
Reinstalled the vacuum hose and capped far end of hose to do a hose test. (same results as pump alone)
