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 O ring and you're back in business.
I will place a piece of parchment over the baking sheet and add another layer of fruit. After it is frozen solid, the fruit can be taken off the tray and placed in freezer bags if needed.
I have pelo adverse vacuum performance change with the catch can in place. It just catches any oil. I still smell oil vapor when the pump first starts up, but not nearly as much. I've only emptied the can once or twice since I've had it installed. I slightly over filled the pump and it blew out into the can, then ran it with the FDer valve open for a few minutes. Nothing got past the can. I used the outside port as IN and the middle one as out. I did take the port off and the longer one should be the inlet port. It's not a great deal longer.

Truth be told, there isn’t much of a difference in terms of interface, but the Pharmaceutical models do offer a bit more customization in terms of settings. The Home Pro models however get the job done just as well and have bigger capacity for the money.
Nor is it affordable for all of our extended family to eat gluten-free for the holiday meals. This challenge has been easily remedied with my freeze dryer.
For the price of a large home freeze dryer one can have 48 servings of premium freeze dried beef delivered to their home every month for a year with promo code “jdr“.
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.
So I corrected the oversight - I drilled and tapped the elbow to add the port. Here is more info a picture. It worked great today when I flushed the pump to clear out the gunk.
Drying things out played a roll as well as the added insulation. We had 3.5 weeks of constant rain here in central NC with humidity over 95% and temps near 95F in the beginning and tapering down to 80F by the end of the rain. The condensation on the front panel around the seal had water running down the front of the Freeze Dryer constantly during the entire cycle, not just the freeze cycle. I initially went into the FDer to simply stop the humdity from reaching the outer chamber shell and freezing.
Foods with lots of seeds can be freeze dried but usually take longer. That’s because the seeds hold moisture. If you’re processing strawberries, raspberries, blackberries, tomatoes, and kiwis you’ll need to add extra time. I like to add at least 12 hours when processing these foods.
Never allowing the unit to heat up to ambient temps - Quickly removing the ice from the chamber and starting the next cycle while the chamber unit is still very cold.
Karla Abreu says: 2 years ago I just think pressure canning is the easiest way to preserve food and know it is totally sterile. And it is relatively easy
Purchasing a freeze dryer can be an excellent investment for those interested in food preservation, emergency preparedness, or simply enjoying homemade snacks that last longer get more info without losing their quality.
