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

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...
I'm brainstorming ideas on what to do with it. Gourmet astronaut ice cream? Crispy cheesecake? Some weird variant on beef jerky?

It failed to reduce the moisture in the oil... I'm in the process of modifying it to catch and suspend the moisture in the container long enough for desiccant beads to absorb the water. The air flow comes into the inlet, down the central pipe to the bottom of the screen and filters up through the beads and out the top. I know this was like forever ago, but I thought I would respond anyway. I haven't been on much in a while, I only run my freeze dryer in the winter. So I think you'll find it's a lot harder to remove water vapor from a vacuum than just using desiccant, as the vacuum will just pull the water out of the desiccant.

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.
Oil Mist Filter: Both pumps come with an oil mist filter. However, the Premier Pump’s oil mist filter allows for no oil spray at all and it will last much longer.
Some special food items cannot be prepared with regular appliances – especially if you need them prepared at a high volume. This is where specialized cooking equipment are helpful.
The evaporator coils that touch the surface of the more info stainless steel vacuum chamber reach about -42 F. With food in the chamber and because the location of the thermister is on the middle shelf of the four shelves, the temperature it records is going to range from -25 to -30 F in the 9 hour default freeze time. This temperature is very adequate for freeze drying the food.
Lastly, don’t forget about finding a used freeze dryer on craigstlist.org or other similar classified-based websites. There are plenty of used and well-kept freeze dryers out there that you can get for half the price.
Steam cooking is healthy for you, and also fast and efficient. It also presents a ideal way of keeping cooked food warm without drying out.
With simple-to-use dial controls and straightforward cycles, It truly is an excellent decision for those who dislike fidgeting with buttons and configurations.
I love that the small freeze dryer can be placed on a kitchen counter. Having it in the kitchen makes it convenient and always ready to start the freeze-drying process.
Most pharmaceutical or laboratory-grade freeze-dryers have to be purchased from licensed manufacturers. These sales often need to be done over the phone or in person with an equipment salesman, though those can be found online. Some options are also available online at places like Amazon.
