Do you have any vacuum gauges at all to test the pump? ( Though I doubt that is the problem based upon your tests )
The shelf heaters can be set to automatically control the rate of sublimation during the primary drying cycle.
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.
Over night the FDer warmed up and the next morning we had a massive puddle under it - running off the counter onto the floor. I cleaned up the mess, but the next day the puddle was even bigger. On the 3rd day it was back again just as large even though I left a large towel under the FDer.
6. Warranties and Support: Look for models that come with warranties and reliable customer support options.
Freeze drying is a dehydration process that removes moisture from food while preserving its structure and nutritional value by freezing it first and then creating a vacuum around it.

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.
The characteristic timeless design is as popular today as in the 50's. It was first developed by civil engineer Alvar Lennin.
AN8 male fittings are 3/4 X 16tpi. Should be able to get one that will work in this application. Also, there filters that use metric threads, might be easier to deal with.
Out of caution, I have only ever taken mylar bags in a checked bag and I’ve never had a problem. I know of people who have taken them in carry-on bags as well without issues.
Freeze dried salsa One of our favorite things to freeze dried is our homemade salsa. It tastes much more like fresh than it does when canned. It reconstitutes very quickly and is delicious to eat as a dip or added to Buy Now spaghetti sauce. We also like to sprinkle it on popcorn.
6) The first place was the cold return line into the compressor. It had insulation, but a second layer helped stop the constant drips. I used black electrical tape to secure the foam.
9) The last port to insulate required the top be removed. Before I removed the top cover I replaced the side covers. This keeps the back and front panels structurally rigid. Do not remove both the side more info panels and top or you will have problems reassembling as things get very loose.
Slight delay at customs but my head was spinning at how fast this was resolved for something that was out of there control! Bravo!
