Do you have any vacuum gauges at all to test the pump? ( Though I doubt that is the problem based upon your tests )I will place a piece of parchment over the baking sheet and add another layer of fruit. After it is frozen solid, the fruit can be taken off the tray and placed in freezer bags if needed.
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.
When isolated, the pump seems to behave well. Short of putting a meter on the pump, my impression is that it is operating properly. I'm considering investing in a good meter to verify that it is reaching a good ultimate vacuum.

Monitoring the FDer internal temps and once I see -40F I start the dry cycle, except for high sugar content food which I give an extra hour. I'm still experimenting with Ice cream and a few fruits to determine optimal freeze time to get the best results. The cooling cycle ends up much shorter.
And they are so much Know More more flavorful than what you buy at the store. Again, I like to powder vegetables and use them to thicken soups. My family doesn’t even recognize when I add powdered zucchini to spaghetti sauce!
