4) I made a plastic shield to protect the main circuit board of the FDer. it simply slides into place and protects the top and both sides of the board from condensation.
You can freeze dry things with fat and oils in it. The point isn’t to completely get rid of all the fat, but to reduce it. The reason being is for the storage process.
Truth be told, there isn’t much of a difference in terms of interface, but the Pharmaceutical models do offer a bit more customization in terms of settings. The Home Pro models however get the job done just as well and have bigger capacity for the money.
I removed the side covers and found the water dripping from the chamber insulation. I called up HarvestRight to ask for ideas on how to avoid this in the future.
It’s super simple, if you aren’t running an Oil Free pump (which we strongly suggest), you should change the vacuum pump’s oil every 20-30 runs (approximately once every month or two with daily use) and ensure the interior chamber as well as your trays are cleaned frequently.

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.
To maintain stability of drugs, vaccines, and biologics, freeze-drying is one of the most prominent techniques the pharmaceutical industry utilizes. Since many pharmaceutical compounds are sensitive to moisture and temperature changes, their potency can be conservatively preserved through lyophilization.
Freeze dried salsa One of our favorite things to freeze dried is our homemade salsa. It tastes much more like fresh than it does when canned. It reconstitutes very quickly and is delicious to eat as a dip or added to spaghetti sauce. We also like to sprinkle it on popcorn.
We packed freeze dried milk and cooked chicken strips as well as an assortment of snacks. One checked bag was dedicated to food, and it traveled very well.
