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.
Places like Craigslist are great for buying more or less anything, but there are more specialized online stores for used electronics, such as EquipNet.com; you can also find used freeze dryers on eBay and Amazon.
Ideal vacuum pressure and drying temperature is maintained for each material and preserves freshness and potency
Finding used freeze dryers isn't easy. That's because most people who get them consider them a long-term investment. As such, they hold on to them for years. However, a used freeze dryer or two sometimes makes its way onto the market.
Removing the ice from between the chamber wall and the insulation (hopefully will never have to do this again)
Agree entirely on the fittings! After many emails and phone calls to HR, some advice that didn't pan out, and some parts replacement, the unit is back in business! Turns out it was the wire passthrough for the heater wires.
seis) 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.
It appears that the ice build up inside the chamber sublimates as well as the ice in the food. Eliminate the ice and the process is faster, and less water ends up in your oil.
Oil Mist Filter: Both pumps come website with an oil mist filter. However, the Premier Pump’s oil mist filter allows for pelo oil spray at all and it will last much longer.
For kitchens that serve a lot of breakfast foods, quick and efficient commercial toasters are essential.
Never buy a freeze-dryer that isn’t sold by a reputable brand or any location that could have tampered with the device. Most companies vet their authorized resellers extensively, so they may be safe. However, used units sold elsewhere may not have been re-tested by the manufacturer for issues.
There are 3 ports on the chamber that I made slits in the plastic to get around and taped them up once around them. Do not tape to the insulation. Tape only to the vapor barrier plastic. It doesn't take long, just be careful. After the plastic is in place and secure around the chamber I sealed the plastic to the back of the front and back panels using the packing tape. All the way around the front and back of the chamber to completely seal the chamber from outside air and humidity.
Before you know it, you’ll be storing food and experiencing the many joys that cooking has to offer.
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 same phenomenon before I installed an isolation valve on my pump.
