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.
The entire process is automated using highly intelligent built-in sensors that know exactly when the food is properly freeze dried. Just press start and the freeze dryer will beep when finished.
Long ago. and B. I don't have the test equipment I did then. I guess what I'm saying is don't be afraid to get too technical with me in your answers. What I wouldn't give for a helium leak detector right now...
Do you have any vacuum gauges at all to test the pump? ( Though I doubt that is the problem based upon your tests )
Removing the ice from between the chamber wall and the insulation (hopefully will never have to do this again)

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.
1) I installed a 3/4" wide high density closed cell foam in the gap between the front of the chamber and the back of the front panel - just what Harvest Right suggested except all the way around (the first picture shows the gap). Use your fingers to push it into place. It needs to be tight against the inside panel. I then installed a vapor barrier around the entire FDer chamber. I used 7mil plastic and clear packing tape.
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 get more info conditions.
The shelf life of canned and dehydrated food is approximately two to three years, while freeze dried food easily lasts eight to ten times as long.
AN8 male fittings are 3/4 X 16tpi. Should be able to get one that will work in this application. Also, there filters that use metric threads, might be easier to deal with.
Harvest Right’s large Pharmaceutical is the solventless’s industry standard freeze dryer for a reason: they’re affordable, can dry a lot of hash in 24 hours, and are easy to set up. We sell more of them than just about anyone else in the industry to hash makers everywhere.
Ask yourself useful issues. Could you very easily approach entire meals in a single cycle? Or is it very best to system different types of foods individually? Does one know how to load the food trays?
Lately, some people have been advocating some very potentially hazardous food preservation and storage practices on foods meant for room temperature storage.
Is it as cheap as buying at the store? No. But properly freeze-dried and stored meats can last ten years or more without refrigeration. The freeze-drying process can be challenging, but those who have the time and patience should consider doing it.
