The characteristic timeless design is as popular today as in the 50's. It was first developed by civil engineer Alvar Lennin.
I found out the hard way about the anti-drainback seal when I first tried the filter and got... nothing. I did do some research afterward and learned, as you point out, that there are some filters than don't use the seal but by then I was committed. Fortunately, it wasn't all that hard to remove it, but definitely better not to have to.
I have one of those hand held heat guns (inexpensive from HF), but I was afraid of accidently burning the insulation. My gun gets very hot! I do the same technique with a fan, shock the ice and listen for the cracks as it separates from the chamber wall.
Most foods can be freeze dried; however, items with high fat content like avocados may not preserve as well as low-fat foods like fruits or vegetables.
Upon turning off the pump (no 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.
The longevity of freeze dried food depends on the what the food is and how it is stored. When stored in a mylar bag with an oxygen absorber, many foods can last up to 25 years. If stored in a glass mason jar with an oxygen absorber and a vacuum sealed lid, food can last about 5 years.

Colin Arnason Albert was Shop Now very responsive and answered any questions or concerns I had. Great product and I’m enjoying using it.
A funny lesson I learned is that we no longer freeze-dry many fruits or vegetables. I know this goes against what most preppers say but I’ve come to a different conclusion. We did tons of fruits and vegetables at first but considering the time it takes we found that we are better served by spending that precious freeze drying usage on more expensive items like meats, eggs, and complete meals.
You will be addicted once you realize how much you can freeze dry, how easy it is and how much you can preserve for your household in a short amount of time.
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.
Both pumps come with an oil mist filter. However, the Industrial Pump’s oil mist filter allows for no oil spray at all and it will last much longer.
If you have gluten sensitivity and not Celiac or a gluten allergy, you might be ok with gluten and gluten-free in the same machine.
