Reattached hose and ran another full system test (results, 750 mTorr lowest steady reading - looking through the oil level window, some bubbling seen in oil even after an hour of pumpdown - some "air" noises from pump)
. 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.
For ground meats, it’s a good idea to cook and then drain off as much grease as possible. I like to rinse ground meat before putting it in my machine to get rid of even more fat.
It freezes the product and lowers pressure to remove ice by sublimation. Sublimation is the transition of a substance directly from the solid to the gas phase without passing through the liquid phase.
