4) I made a plastic shield to protect the main circuit board of the FDer. it simply slides into place and protects the top and both sides of the board from condensation.
. We have some really great 'techy' type guys here who are, as they have been exploring the FD mechanics and sharing that in their posts, writing what is turning out to be a 'troubleshooting manual' for us less capable folks.
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.
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.
I've run the system in countless tests including over filling the pump and running the pump without a load (both result in lots of oil spitting out the exhaust port of the pump). I've drained the catch can twice, once with over 5 oz of oil in it, but have not collected any oil downstream in the jar so the system is performing well.

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.
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.
Control of the amount of time a material is held at the ultimate freeze temperature before the drying cycle is started.
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.
- Nutritional Preservation: This method retains about 97% of the original nutrients in food, making it superior to other preservation methods like canning or dehydrating.
