Be aware that it is very important to drink liquids when eating freeze dried foods that haven’t been reconstituted.
You can freeze dry things with fat and oils in it. The point isn’t to completely get rid of all the fat, but to reduce it. The reason being is for the storage process.
I would prefer those fittings to have internal Este 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.
Most foods can be freeze dried; however, items with high fat content like avocados may not preserve as well as low-fat foods like fruits or vegetables.
•The shelf heaters can be set to automatically control the rate of sublimation during the primary drying cycle. Through this process, the unit has control of the attendant vacuum pressure.
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. 1
Once we got into the groove of freeze-drying food, we have been extremely pleased with the purchase. But know this going in if you’re thinking this is an “easy button.” It’s not. In fact, in many ways it has changed our lifestyle. For example, we now often cook for a family of 8 even though it’s just us and the two kids.

Based upon your work experience you probably know more about vacuum pumps than most of us. Chasing a vacuum leak can be frustratingly difficult.
Not all of us are technical experts (the 'not' category includes me) but I hope someone who can help you will come along soon.
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.
Both pumps come more info with an oil mist filter. However, the Industrial Pump’s oil mist filter allows for no oil spray at all and it will last much longer.
No longer do I have to ask what every ingredient is in each dish. And I don’t have to ask for the sour cream to be left out of the mashed potatoes. I can take a meal of turkey, ham, mashed potatoes, green bean casserole, and yams that I freeze dried throughout the year.
