I'll be trying combined foods next. The Small size works here. The pictured instructions are helpful. The reading material gets you off to a good start and you can get Harvest Right App for endless possibilities!
Reattached hose and ran another full system test (results, 750 mTorr lowest steady reading - looking through the oil level window, some bubbling seen in oil even after an hour of pumpdown - some "air" noises from pump)
I have no 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.

Over night the FDer warmed up and the next morning we had a massive puddle under it - running off the counter onto the floor. I cleaned up the mess, but the next day the puddle was even bigger. On the 3rd day it was back again just as large even though I left a large towel under the FDer.
By this point, most of my son’s friends know about his dietary restrictions more info and it doesn’t bother them. My son takes rehydrated freeze dried meals to school banquets and to other social gatherings.
22F, achieved by dividing nove hours by 110F (the difference in food temps). We both know that the FDer doesn't do linear as the temps fall faster early on and slowly peak to max low temps, but the food freeze time might be a tad more linear than the FDer as food is denser and must be frozen throughout.
The differing vacuum levels during the system tests would be consistent with either a door seal leak or an drain valve leak.
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.
A bit of background on me - I used to work in a sold state fabrication lab (university research lab) and had a lot of hands-on work with ultra-high vacuum equipment. The pumping we do for freeze drying was what was required to just start
Reinstalled the vacuum hose and capped far end of hose to do a hose test. (same results as pump alone)
And therein lies the cons to buying a freeze dryer. It takes time to make them cost effective. Depending on humidity in your area, a single run can take up to two days to complete.
Odds are the problem is the vacuum hose or its end connections, the drain valve, or the door gasket. Based upon my experience I'd double check the fittings while installed on the FDer.
Have an understanding of which kind of food pretreatment is needed to use the device. To ensure the get more info freeze-drying approach is productive, you’ll must understand how to get ready food.
