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
The entire process is automated using highly intelligent built-in sensors that know exactly when the food is properly freeze dried. Just press start and the freeze dryer will beep when finished.
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.
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.
So I corrected the oversight - I drilled and tapped the elbow to add the port. Here is a picture. It worked great today when I flushed the pump to clear out the gunk.
Oil Changes: This new Premier 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.

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.
My husband has been contemplating cost effective alternative ways to get oil-less vacuum happening... what would the specs needed be, since I don't have a pump to look at. Hopefully I asked that in a way that makes sense.
A walk-in freezer isn’t an appliance that you would find in a domestic kitchen! But, they’re very common in restaurants.
Obviously things like ice cream and marshmallows you would want to let the freeze cycle run longer. When I'm ready to start the drying cycle, I open the door, remove the insulator, and check the temperature of the food on the trays with an infrared thermometer. As long as it's below -10F I start the dry cycle. A side note for TonyC, have you ever thought about attaching a mirror to each side of the tray rack to reflect the radiant heat back in to the Freeze Dryer for sale trays? I've looked at some mirror finish stainless on ebay, and it looks like you could do it for about $40. Not sure if it's worth a try or not. I would think it would let you get more water out in a cycle because the radiant heat wouldn't be warming the ice on the chamber walls. Just a thought....
