What I presume was happening was that condensation was building up on the cooling coils between the insulation and the chamber and freezing. When I finally turned the FDer off it took 3 days for the ice buildup to melt and slowly soak through the insulation and drip onto the counter.
No way, that's pretty cool. Do you have a picture of it, how much are we talking here? 600 lbs seems rather unlikely; I'm thinking more like 60.
I’d recommend that anyone stick with buying any freeze-dryer or heavy equipment directly from the manufacturer. And if you’re ready to shop for a Harvest Right, you can use this link to shop current sales.
The best place to buy a freeze dryer is directly from the manufacturer’s website. That way, a warranty will be included, there’s a guarantee the machine wasn’t tampered with by anyone (even by accident), and buyers can get additional information from customer service.
One oil free pump. The oil free vacuum pump can be used with any size freeze dryer. They are quiet, fast, and easy to use. The Harvest Right oil free vacuum pumps do not require oil changes and do not require regular user maintenance.
So I corrected the oversight - I drilled and tapped the elbow to add the port. Here is a picture. It worked great today when I flushed the pump to clear out the gunk.
8) The vacuum port was up next. You can see the condensation on the brass fitting. That means cold is escaping and heat is getting into the chamber. This small section was placed inside the panel.

Oil Mist Filter: Both pumps come with an oil mist filter. However, the Premier Pump’s oil mist filter allows for no oil spray at all and it will last much longer.
It is fun to experiment with innovative preservation methods, but carefully consider the consumer purchasing points above: Know before you go.
I didn’t know you had this feature till one day i got an email and that got me to the sitio were i started looking around. This way I can take a couple months instead of hitting my saving and paying for it at once.
Money Back Guarantee. Customers may cancel their orders, prior to shipment, for a refund less a 3% fee to cover the credit card charges incurred by Harvest Right. Once the freeze dryer(s) ships, if it is within 30 days of ship date, customers may return their freeze dryers for a refund less shipping costs and less a restocking fee of 15%. All sales of Harvest Right Freeze Dryers after February 1, 2019, are covered by this warranty.
The key is to freeze as fast as possible then dry as slow as possible. The freezing stiffens the cells so that when it is dried, it still maintains it's shape and texture.
Without an pump isolation valve I would expect some air to flow back into the chamber through the pump resulting in the steady rise you witnessed. I saw the get more info same phenomenon before I installed an isolation valve on my pump.
