And therein lies the cons to buying a freeze dryer. It takes time to make them cost effective. Depending on humidity in your area, a single run can take up to two days to complete.
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.
I would prefer those fittings to have internal O 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 Este ring and you're back in business.
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.
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.
Given the outrageous cost of freeze dried fruit, I have also been watching e-bay for an inexpensive freeze dryer, with the thought of using it to dehydrate stuff that could then be added to chocolate centers, adding flavour without adding liquid. I make a strawberry centre that uses strawberrry puree, freeze dried strawberry powder, as well as a bit of strawberry compound to produce an intensly strawberry experience.

There are 3 ports on the chamber that I made slits in the plastic Know More to get around and taped them up once around them. Do not tape to the insulation. Tape only to the vapor barrier plastic.
