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.

It is the responsibility of the homeowner to verify that the hired contractor furnishes the necessary license and insurance required for the work being performed. All persons depicted in a photo or video are actors or models and not contractors listed on this site.

Ideal vacuum pressure and drying temperature is maintained for each material and preserves freshness and potency

One of the reasons I like the small freeze dryer is the size. At the same time, my large freeze dryer takes up space equivalent to a clothes dryer—the small one doesn't.

The one "gotcha" I encountered in making this is that a typical car oil filter attaches with a 3/4x16tpi threaded pipe. I could find pelo such pipe anywhere. My solution was to use instead a 3/4x16tpi bolt, and then drill a hole through it.

4) I made a plastic shield to protect the main circuit board of the FDer. it simply slides into place and protects the top and both sides of the board from condensation.

These enormous freezers are mandatory for any food service operating at a very high volume. Commercial kitchens require plenty of room to store frozen food and this is why a Know More walk-in is needed.

Hey there, fellow self-reliant folks! If you're all about preparedness and want to take your food preservation game to the next level, you've probably considered getting yourself a freeze dryer. But let's be honest – freeze dryers aren't exactly known for being wallet-friendly.

No commercial kitchen would be able to function without a proper ventilation system. There are many different kinds of commercial exhaust hoods available for your specific kitchen and requirements.

While I had the unit apart to replace the display I decided to correct the water condensation problem. If you find yourself using your FDer in the same conditons as we do you may want to consider modifying your FDer to keep the condensation from your FDer control circuit and display cards. Here are the steps that I followed to minimize what the NC high humidity climate does to my FDer.

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.

Presumably you have one of the medium sized units that is used for dried flowers, taxidermy etc - those are most common on the market. Lab supply places have very small ones for scientific samples. Food oriented freeze dryers tend to be factory sized.

Not all of us are technical experts (the 'not' category includes me) but I hope someone who can help you will come along soon.
