I have pelo adverse vacuum performance change with the catch can in place. It just catches any oil. I still smell oil vapor when the pump first starts up, but not nearly as much. I've only emptied the can once or twice since I've had it installed. I slightly over filled the pump and it blew out into the can, then ran it with the FDer valve open for a few minutes. Nothing got past the can. I used the outside port as IN and the middle one as out. I did take the port off and the longer one should be the inlet port. It's not a great deal longer.

No way, that's pretty cool. Do you have a picture of it, how much are we talking here? 600 lbs seems rather unlikely; I'm thinking more like 60.
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.
The only way I know to filter the water vapor out would be a cold trap. They usually use liquid nitrogen or dry ice to keep the temperature low enough that all the water condenses out. Obviously you would need a supply of the liquid nitrogen or dry ice that would probably not be cost effective for most of us. The other option to get that cold would be to use a cryocooler and build a cold trap around it. It could be done, but would be pretty expensive. I've been watching some electronics on ebay that have cryocoolers in them, but the cheapest I've seen is around $600. Still not a cheap option, but you wouldn't need dry ice or liquid nitrogen to feed it.
Granted, most of that time is the freeze dryer doing all the work, but the process is not without effort. Once the food is ready it must be put into appropriate containers with oxygen absorbers and sealed properly so they can last.
The bottom line regarding freeze-dried food is that hoe freeze dryers are an investment! An investment that pays you back and makes you more resilient in the process.
One of the many joys of having a working freezer is the potential that it holds. While cooking may not be everyone’s forte, saving time usually is, and this is one of the benefits a freezer affords. By scheduling particular days and reserving them exclusively for the preparation of a week’s worth of meals, you’ll save not only a significant amount of money, but time.
Because the freezing is fast, relatively few cell walls are ruptured which means it can be rehydrated with much less loss of quality.
The shelf life of canned and dehydrated food is approximately two to three years, while freeze dried food easily lasts eight to ten times as long.
5 Posted September 16, 2015 (edited) Gypsyman: Proof again that "great minds think alike". In my initial pondering, I thought using an oil filter base would be a logical approach -- but I didn't have one handy and figured my car might miss it. Besides, one of my goals was to keep this affordable, and they tend to be a little pricey.
Studies show the average American family wastes about $2,500 per year between produce and dairy that goes bad, leftovers that don’t get eaten, and items that expire or get freezer burn. All these food items could be freeze dried and put on the pantry shelf ready to taste great next week – or in 20 years.

Fermenting foods is perhaps the oldest food preservation method and has grown in popularity in recent years due to their touted “gut”, probiotic, and other additional health benefits. Fermenting at home is an inexpensive way to control what goes inside yo
