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.
Never allowing the unit to heat up to ambient temps - Quickly removing the ice from the chamber and starting the next cycle while the chamber unit is still very cold.
I think a community-built troubleshooting manual is a great idea. These machines are simple in some ways, and more complex in others, and having a lot of eyes on the problem is always good.
Its patented technology and large capacity set it apart, offering reliable and consistent freeze-drying results that maintain the highest quality standards.
With their assist, it is possible to maintain uniform thickness and Room amongst food slices, advertising and marketing even drying and optimum texture.

Do you think it's okay to just purchase a reducer to go from the size of the exhaust to the size of the hose that came with the can? Hopefully I said that in a way that makes sense! As well, does it matter which port is used as "in" and which as "out"? Thanks so much, Jen Hi Jen, Sorry to be gone so long. I did exactly as you proposed.

There are certainly bad shops you want to avoid, and in today’s article, we’ll be taking a look at the best places to buy a freeze dryer, so we can avoid the worst.
A bit of background on me - I used to work in a sold state fabrication lab (university research lab) and had a lot of hands-on work with ultra-high vacuum equipment. The pumping we do for freeze drying was what was required to just start
You can determine when the product is dry by feel or by calculation of the amount of water remaining in the product.

Removing water quickly is very important because the longer a harvested plant or compound retains water, the higher the chance it has of spoiling, losing nutrition, and losing potency.
Dehydrators take the water off the surface first, then water eqilibrates with the surface, more water is drawn off the surface. You are left with a shrunken item, with some residual water. Makes gorgeous leather.
Upon turning off the pump (pelo isolation valve on the pump - standard setup), the chamber pressure rose quite rapidly going to 2000 mTorr and continuing up in a couple of minutes or so.
3) Inside the front panel I installed a plastic shield over the Know More display card and a water deflector just below the hole to route the exterior condensation to an 11x17 pan beneath the FDer.
