Be aware that it is very important to drink liquids when eating freeze dried foods that haven’t been reconstituted.
I thought an easier way to see what was happening would be to make a time lapse video of an entire freeze drying cycle. As I was about to prepare some apples for freeze drying yesterday, I thought it would be a good time to do that -- so out came the GoPro.
In fact, my son’s friends often comment that they wish they could have his freeze dried meals rather than whatever they are eating!
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.

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 Completa 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.
This is the case with meats as well. The trick with meats is to cook out as much fat as possible, then run it under water to remove even more fat. However, you can also freeze dry Shop Now raw meat as well.

The only way I know to filter the water vapor out would be a cold trap. They usually use liquid nitrogen or dry ice to keep the temperature low enough that all the water condenses out. Obviously you would need a supply of the liquid nitrogen or dry ice that would probably not be cost effective for most of us. The other option to get that cold would be to use a cryocooler and build a cold trap around it. It could be done, but would be pretty expensive. I've harvest right home freeze dryer been watching some electronics on ebay that have cryocoolers in them, but the cheapest I've seen is around $600. Still not a cheap option, but you wouldn't need dry ice or liquid nitrogen to feed it.
Freeze drying seasoned squash and zucchini One of my favorite things to freeze dry is vegetables. It’s so easy to put them in soups or casseroles. Once onions or garlic are processed, they are great to add to food.
The process consists of stages: primary drying, where most of the water is removed, and secondary drying, which removes unfrozen water molecules to preserve the product.
