Teresa said on August 8, 2019 at 12:40 am How big is a medium freeze dryer and if I buy one what do I have to buy to make it work like I see u have to have oil and buy a pump along with the freeze dryer doesn’t it all comes with everything to make it work
The only downside is that the interior is now so cold that defrost time has doubled! I use a large high volume fan to defrost the unit, not the heat trays. It used to be a 15 minute job, now it is closer to 30 minutes.
After the 3rd cycle I had hit my 20 cycle oil limit so it was time to change the oil. This time I took the time to add a flush port to my pump. When I replaced the plumbing with larger diameter brass and a cutoff valve I did not think to add the oil flush out port.

Remove all ice every oito hours of drying time. It is amazing how much faster the drying time drops doing this. A side benefit is water vapor does not contaminate the oil as fast. I've gotten up to 20 cycle per oil change by carefully monitoring the oil and water.
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.

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.
We’ve bought six so far with two more on the way. But families and individuals considering getting their own can and should as long as they go in with their eyes open.

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.
adding insulation on the 3 ports on the chamber (One time thing - the drain and vacuum ports are very easy to get to)
