On that point, I was first introduced to home freeze dryers while overseeing the guard force at the Embassy in Baghdad.
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)
My husband has been contemplating cost effective alternative ways to get oil-less vacuum happening... what would the specs needed be, since I don't have a pump to look at. Hopefully I asked that in a way that makes sense.
With the combination of pharmaceutical and food products needing to be more shelf-stable than before, acquiring ideal freeze-drying machinery is crucial. Modern freeze driers have much more sophisticated control of temperature, pressure, and moisture which guarantees the quality of the product as well as meeting regulatory standards.
As I've shown you, the Small Harvest Right Freeze Dryer is the most affordable freeze dryer. However, if that's not what appeals to you, I know you can't go wrong with the other models. After all, I own the large model.
Simply press start on the touch screen and the patend Smart Freeze technology senses when it's done.
And once you have resolved your issue I hope you will stay around and talk to us all about what you have been drying in your machine, etc. 1
Once we got into the groove of freeze-drying food, we have been extremely pleased with the purchase. But know this going in if you’re thinking this is an “easy button.” It’s not. In fact, in many ways it has changed our lifestyle. For example, we now often cook for a family of 8 even though it’s just us and the two kids.
Another reason to buy a freeze dryer instead of already freeze dried food is that you can choose to freeze dry whatever you want.
Pre-frozen food takes less time to process since the machine doesn’t have to completely freeze the food. Your climate (humidity and temperature) can also affect the cycle length. My average load takes around 24 hours, but it can be significantly longer.

Do you think it's okay to just purchase a reducer to go from the size of the exhaust to the size of the hose that came with the can? Hopefully I said that in a way that makes sense! As well, does it matter which port is used as "in" and which as "out"? Thanks so much, Jen Hi Jen, Sorry to be gone so long. I did exactly as you proposed. I purchased a brass reducer and pushed the blue hose over it.
Cooked eggs can be freeze dried, but they tend to be rubbery when reconstituted. If you want to freeze dry cooked eggs, I recommend slightly undercooking them and then rehydrating them with boiling water. It will finish cooking them without making them rubbery.

I, too, have noticed a significant difference when I defrost Know More mid-cycle. I do that routinely now. I carefully use a heat gun to "shock" the surface of the ice, moving back and forth across it fairly swiftly, which causes it to crack and separate somewhat from the cylinder.
