After the 3rd cycle I had hit my 20 cycle oil limit so it was time to change the oil. This time I took the time to add a flush port to my pump. When I replaced the plumbing with larger diameter brass and a cutoff valve I did not think to add the oil flush out port.
It makes the processing time faster, which means less wear on the machine. If I am preparing fruit, I typically slice it and put it on a baking sheet.
Then, when I reconstitute, I add back the same amount of water to equal the total amount of milk I originally processed. For example, if I processed 4 cups of milk, I add to the milk powder enough to equal 4 cups. I prefer to use an immersion blender for the best consistency.
The pros and cons are easy to understand. In fact, there really is only one pro and it’s a huge one. Those who are willing to spend the time and money to freeze dry their own food should do so as long as they’re going to be committed.
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.
The longevity of freeze dried food depends on the what the food is and how it Buy Now is stored. When stored in a mylar bag with an oxygen absorber, many foods can last up to 25 years. If stored in a glass mason jar with an oxygen absorber and a vacuum sealed lid, food can last about 5 years.
The freeze dried food can be used for everyday eating, camping and of course, long term storage. I freeze dry as much as I can while times are good, I won’t plan to freeze dry if I go off-grid or don’t have electricity.

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 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 Perfeito 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.
Out of caution, I have only ever taken mylar bags in a checked bag and I’ve never had a problem. I know of people who have taken them in carry-on bags as well without issues.

You can freeze dry soy and almond milk as well as most non-dairy yogurt, sour cream, and cream cheese substitutes. This has been especially helpful in avoiding food waste, as my son is the only one who uses the non-dairy substitutes, and he rarely is able to finish them before they go bad. I just throw them in the freeze dryer for him to eat later.
