Is a freeze dryer a good investment?
Is Buying a Freeze Dryer Worth it? Buying a freeze dryer is worth the cost for anyone who wants to preserve a wide variety of shelf-stable foods especially in large quantities and to be able to store those foods long-term in airtight mylar bags or containers outside of a fridge or freezer.
Do freeze dryers work?
The freeze dryer cools the material below its triple point to ensure that sublimation, rather than melting, will occur. This preserves the material’s physical form. A freeze dryer most easily freeze dries large ice crystals, which can be produced by slow freezing or annealing.
Why is a freeze dryer so expensive?
Freeze dryers can cost several thousand dollars or more as they must reliably and accurately freeze (to -80 degrees Fahrenheit) and heat foods, using a strong vacuum to remove 95%+ of the water content. Due to parts, labor, and overhead costs, these units reasonably cost $1,060 or more.
How long do freeze dryers last?
So long as you keep the food in ideal conditions, it can last up to 25 years. A good home freeze dryer machine will self-monitor the process. Once the water vapor has been removed, the humidity sensors automatically turn off, so the process is virtually fool-proof.
How expensive is a freeze dryer?
How much is a freeze dryer? Home freeze dryers range in price from $1,995 to $3,495, depending on size and exterior finish.

Do freeze dryers use a lot of electricity?
At peak, the freeze dryer draws about 16 amps, but on the average about 9 to 11 amps (990-1210 watts) of power per hour. A dedicated 20 amp circuit is recommended. Your freeze dryer will cost an estimated $1.25-$2.80 a day, depending on power costs in your area.
How does a freeze dryer work?
Raw or cooked foods are placed in the freeze dryer where they are frozen to between -30 degrees and -50 degrees Fahrenheit. 2. Once frozen, the freeze dryer creates a vacuum in the food chamber. As the food is gradually warmed, the water turns to vapor and evaporates out of the food (sublimation).
