I would prefer those fittings to have internal Este rings and knurled thread on ports (similar to R134a vacuum gauge sets) that do not require high torque compression fittings. Finger tight and you are good to go. You spot a leak, change the Este ring and you're back in business.
The food and pharmaceutical industries crucially rely on freeze drying for the long-term storage of products. This method enables businesses to preserve product quality, extend shelf life, and improve stability.
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.
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.
Freeze drying is a dehydration process that removes moisture from food while preserving its structure and nutritional value by freezing it first and then creating a vacuum around it.
Question for you: I'm impressed by the shortening of cycle times. Obviously some of that 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.
3) Inside the front panel I installed a plastic shield over the display card and a water deflector just below the hole to route the exterior condensation to an 11x17 pan beneath the FDer.

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.
Then I just have to take rolls and a gluten-free pie for my son. It’s much less stressful on everyone, and my son doesn’t feel that he’s being deprived of having traditional holiday foods.
Another best practice is to set up a station. This will take space. Having a freeze dryer, freezer, prep table, and processing area all together has been a good decision. It can all be done in a large kitchen, but the machines website are noisy and a freeze-drying project can take up a lot of space.
The next way to save money is to watch Harvest Right's website for seasonal sales and promotions. Sometimes, patience pays off in the form of significant discounts.
