I would prefer those fittings to have internal O rings and knurled thread on ports (similar to R134a vacuum gauge sets) that do not require high torque compression fittings. Finger tight and you are good to go. You spot a leak, change the O ring and you're back in business.

It's awesome! I don't have a freeze dryer yet but am planning to place an order tomorrow. I am super curious how Kerry's scroll pump is holding up... eliminating the oil from the equation would make this whole thing SO much easier.

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.

This new Industrial Pump rarely needs to have the oil changed or filtered. The pump has a gas ballast feature that makes it so water does not stay in the oil. Because of this, the oil in the pump will be pristine and clear, even after 30 or more batches.

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.

The differing vacuum levels during the system tests would be consistent with either a door seal leak or an drain valve leak.

The unit can also connect to and communicate the freeze dryer cycle data to a nearby PC through an ethernet cable.

Colin Arnason Albert was very responsive and answered any questions or concerns I had. Great product and I’m enjoying using it.

Are we trying to rip people off? On the contrary, our beef cubes are actually an exceptional value considering the four-pack offers 48 adult servings with 24 grams of protein each.

7. Energy Efficiency: Evaluate the energy consumption of different models since this will affect your electricity bills over time.

Another best practice is to set up a station. This will take space. Having a freeze dryer, freezer, prep table, and processing area all together has been a good decision. It can all be done in a large kitchen, but the machines are noisy and a freeze-drying project can take up a lot of space.

The set up booklet was easy to follow and the initial bread run went smoothly. I do find the touch screen very sensitive get more info and have made a couple taps in error. An error correct button might be helpful. Now the learning curve begins as the food is processed.

The process consists of stages: primary drying, where most of the water is removed, and secondary drying, which removes unfrozen water molecules to preserve the product.
