The oxidizer packets are a one-time use, although the mylar bags could possibly be cut down and reused. Cost of vacuum pump oil starts at $20 a gallon, although that oil can be filtered and reused. An oil-less pump is also an option but will be an upfront cost of
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"?
Be wary of buying freeze-dryers that come from locations where the unit could have been tampered with or damaged, even by accident.
Then I hit the Ice edge with a large flat blade screwdriver and the entire sheet comes loose in one piece. I may try the gun again using your technique.
Monitoring the FDer internal temps and once I see -40F I start the dry cycle, except for high sugar content food which I give an Em excesso hour. I'm still experimenting with Ice cream and a few fruits to determine optimal freeze time to get the best results. The cooling cycle ends up much shorter.

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.
Freezing is a simple, quick way to preserve foods. Fruits freeze well and retain their distinct fruit flavor. Texture is usually softened somewhat by freezing, but serving partially frozen fruit with ice crystals will compensate for texture changes.
I have one of those hand held heat guns (inexpensive from HF), but I was afraid of accidently burning the insulation. My gun gets very hot! I do the same technique with a fan, shock the ice and listen for the cracks as it separates from the chamber wall.
White rice, more commonly known as polished rice is a main food source for over half of the world’s population. Rice is an excellent addition to home food storage because it’s versatile, high caloric value, and long shelf life. Families should store about
This does not address the food quality after that time, only the food safety. However, no real data exists on the shelf-life of home freeze-dried products, because the company that invented and manufactured the first home freeze-dryer began sales in 2013.
Since 2000, Extension has been warning consumers about canning cakes and breads. While this process has much appeal, it does not destroy the organism that causes botulism.
Run full system test with pelo more info food in chamber (results, 630 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 found out the hard way about the anti-drainback seal when I first tried the filter and got... nothing. I did do some research afterward and learned, as you point out, that there are some filters than don't use the seal but by then I was committed. Fortunately, it wasn't all that hard to remove it, but definitely better not to have to.
Freeze drying lets you say goodbye to food waste by extending the shelf life of your food. Every dollar you save on groceries goes back into your pocket.
