That has lead to me making my own lactose free Greek yogurt and freeze drying it to use for yogurt and sour cream for my son. We also freeze dry lactose free milk for traveling or for any other time we need it. It reconstitutes very well.
It's awesome! I don't have a freeze dryer yet but am planning to place an order tomorrow. I am super curious how Kerry's scroll pump is holding up... eliminating the oil from the equation would make this whole thing SO much easier.
Our electricity was very high when we had it in AK because our electric company charged a lot, but in Texas, it’s very cheap to run. I don’t mind that I can’t freeze dry some things, as most of the things that you can’t freeze dry, you can purchase commercially or they shelf stable as is. For instance, I don’t freeze dry butter, but I do buy powdered butter. Oh, here’s one more potential con:
There is nothing better than fresh herbs! And freeze drying herbs makes them taste so close to freshly picked. I love growing my own herbs in my garden or countertop herb garden and then freeze drying them. They process quickly and are easy to store.
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.
A freeze dryer can be used to preserve entire meals, making it easy to build up a supply of emergency food or just have meals on hand that can quickly be re-hydrated and eaten.
1) I installed a 3/4" wide high density closed cell foam in the gap between the front of the chamber and the back of the front panel - just what Harvest Right suggested except all the way around (the first get more info picture shows the gap). Use your fingers to push it into place. It needs to be tight against the inside panel. I then installed a vapor barrier around the entire FDer chamber. I used 7mil plastic and clear packing tape.
This includes setting as many as five different shelf temperatures, thus allowing the material to dry in phases, at different temperatures. For instance, you might have the material begin drying at 10ºF and increase the temperature in phases until the ultimate final dry temperature is 70ºF.
The evaporator coils that touch the surface of the stainless steel vacuum chamber reach about -42 F. With food in the more info chamber and because the location of the thermister is on the middle shelf of the four shelves, the temperature it records is going to range from -25 to -30 F in the nove hour default freeze time. This temperature is very adequate for freeze drying the food.
Based upon your work experience you probably know more about vacuum pumps than most of us. Chasing a vacuum leak can be frustratingly difficult.
Not all of us are technical experts (the 'not' category includes me) but I hope someone who can help you will come along soon.
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.

Freeze dried Skittles are a favorite in my family. They end up with a crunchy texture. Other candies have a crunchy exterior and an airy interior.
