With simple-to-use dial controls and straightforward cycles, It truly is an excellent decision for those who dislike fidgeting with buttons and configurations.

After a few years of research, I finally decided to purchase a freeze dryer. It was one of the best purchases I have ever made. The only regret I have is that I didn’t buy one sooner.

Suitable placement of food around the freeze drying trays is much more than simply an aesthetic option—it’s a science. Making sure an excellent distribution, without the need of overpacking, is essential for reaching a dependable freeze drying end result.

When isolated, the pump seems to behave well. Short of putting a meter on the pump, my impression is that it is operating properly. I'm considering investing in a good meter to verify that it is reaching a good ultimate vacuum.

It freezes the product and lowers pressure to remove ice by sublimation. Sublimation is the transition of a substance directly from the solid to the gas phase without passing through the liquid phase.

Upon turning off the pump (pelo isolation valve on the pump - standard setup), the chamber pressure rose quite rapidly going to 2000 mTorr and continuing up in a couple of minutes or so.

Question for you: I'm impressed by the shortening of cycle times. Obviously some of that website is from the improvement in insulation on the lines, etc., but I'm wondering how much of it might be from "drying out" of the insulation and outer walls of the freeze drying chamber.

The pros and cons are easy to understand. In fact, there really is only one pro and it’s a huge one. YOU control the food you’re storing away for yourself and your family. 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.

We will still run batches of strawberries or zucchini when there’s nothing else to go in but for the most part we stick to the higher-end foods.

Without an pump isolation valve I would expect some air to flow back into the chamber through the pump resulting in the steady rise you witnessed. I saw the same phenomenon before I installed an isolation valve on my pump.

And, as I write that, the “more is better” side of my brain is freaking out. After all, bigger means better, right? Not always, but read on to learn my thoughts on why the small freeze dryer may be the way to go.
