Odds are the problem is the vacuum hose or its end connections, the drain valve, or the door gasket. Based upon my experience I'd double check the fittings while installed on the FDer.

I honestly think putting a thermometer inside the unit is an excellent idea. I sent the following note off to Harvest Right Support in an effort to gain a little better understanding of the process.

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.

I'm actually working now on making myself a vacuum microwave instead. Got the idea from an article in MacLeans magazine about Domenic and Cindy Duby, who use one to produce interesting flavours. Takes up less space and hopefully produces a product a bit faster. We'll see how it works out.
