Never allowing the unit to heat up to ambient temps - Quickly removing the ice from the chamber and starting the next cycle while the chamber unit is still very cold.
Ideal vacuum pressure and drying temperature is maintained for each material and preserves freshness and potency
Also, since it’s such a large amount of money in question, you don’t want to lose your warranty, which can happen if you buy through resellers.
Monitoring the FDer internal temps and once I see -40F I start the dry cycle, except for high sugar content food which I give an extra hour. I'm still experimenting with Ice cream and a few fruits to determine optimal freeze time to get the best results. The cooling cycle ends up much shorter.
You can count on me sticking around to talk about the food side of things! My wife looked at me a little oddly when I got the freeze dryer, but now she's a fan too. I'm discovering things that it can do that I hadn't expected, such as making low carb snacks.
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.
I cut up a thin flexible cutting board to make the shields and secured them with clear high grade packing tape. The cutting board is stiff but it will fold and hold a 90 degree crease. The shields are not going anywhere, but are easy to remove if necessary.
Using sublimation, the food retains much of its original texture, flavor, and nutrition when rehydrated. Freeze drying is broken down into two simple processes: freezing and vacuum drying. Foods are first frozen to well below 0°F. The colder the freeze the more efficient the next step will be. Once frozen, foods are subjected to vacuum drying. The air and water vapor (gas) are removed from the food processing chamber using a vacuum pump. This includes removing the water vapor that was once inside of the foods. When these two steps are properly completed, the food is dry enough to allow for safe storage at room temperature. Is freeze drying food safe?

Studies show the average American family wastes about $2,500 per year between produce and dairy that goes bad, leftovers that don’t get eaten, and items that expire or get freezer burn. All these food items could be freeze dried and put on the pantry shelf ready to taste great next week – or in 20 years.
5 Posted September 16, 2015 Thanks dsheidt. I was afraid that the AN8 fittings I could find might not be long enough to provide the space needed so that the oil could flow over the top of the filter, especially given my "disk" method of holding up the can.
I started by removing the 3 grocery bags that were holding the 2 thick bags that had at one time held the berries. Struck by how much it looked like a placenta - bag and all!
Most pharmaceutical or laboratory-grade freeze-dryers have to be purchased from licensed manufacturers. These sales often need to be done over the phone or in person with an equipment salesman, though those can be found online. Some options are also available online at places like Amazon.
