There are 3 ports on the chamber that I made slits in the plastic to get around and taped them up once around them. Do not tape to the insulation. Tape only to the vapor barrier plastic. It doesn't take long, just be careful. After the plastic is in place and secure around the chamber I sealed the plastic to the back of the front and back panels using the packing tape. All the way around the front and back of the chamber to completely seal the chamber from outside air and humidity.
Removing the ice from between the chamber wall and the insulation (hopefully will never have to do this again)
Our electricity was very high when we had it in AK because our electric company charged a lot, but in Texas, it’s very cheap to run. I don’t mind that I can’t freeze dry some things, as most of the things that you can’t freeze dry, you can purchase commercially or they shelf stable as is. For instance, I don’t freeze dry butter, but I do buy powdered butter. Oh, here’s one more potential con:
the "real" vacuum pumps on those machines, with ultimate vacuum levels a few more demial places over. I've chased many a leak in my time,but it was: A.
Now that you understand the conditions, you can better understand what happened when we finally turned off our FDer after an extended use in these conditions.
I've run the system in countless tests including over filling the pump and running the pump without a load (both result in lots of oil spitting out the exhaust port of the pump). I've drained the Know More catch can twice, once with over 5 oz of oil in it, but have not collected any oil downstream in the jar so the system is performing well.
Automatically adjusts settings for optimal vacuum pressure and temperature, ensuring the best preservation of your materials.
The easiest way to reconstitute food is with water or broth. I like to weigh my trays before processing them. Then I write the weight and the name of the food on a piece of masking tape and put it on the front of the tray.
A description of the product, including details such as build quality, materials used and reasons to purchase.
Without an pump isolation valve I would expect some air to get more info 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.
The only downside is that the interior is now so cold that defrost time has doubled! I use a large high volume fan to defrost the unit, not the heat trays. It used to be a 15 minute job, now it is closer to 30 minutes.
The system’s shelf heaters and adjustable vacuum pressure ensure controlled sublimation during the primary drying cycle, preserving your materials at peak quality.
The set up booklet was easy to follow and the initial bread run went smoothly. I do find the touch screen very sensitive and have made a couple taps in error. An error correct button might be helpful. Now the learning curve begins as the food is processed.
The food options we had there were extremely limited and full of preservatives. To counter that, my buddy Lance went in with family members on the purchase of a freeze dryer for home use.
