We have some really great 'techy' type guys here who are, as they have been exploring the FD mechanics and sharing that in their posts, writing what is turning out to be a 'troubleshooting manual' for us less capable folks.
Reattached hose and ran another full system test (results, 750 mTorr lowest steady reading - looking through the oil level window, some bubbling seen in oil even after an hour of pumpdown - some "air" noises from pump)
What I should have done was just sent a freeze dried meal that would take me 3 minutes to rehydrate and he wouldn’t have to be stuck in the bathroom for days on end. Lesson learned!
I would prefer those fittings to have internal Este 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.
Now that you understand the conditions, you can better understand what happened when we finally turned off our FDer after an extended use in these conditions.
A freeze dryer can be used to preserve entire meals, making it easy to build up a supply of emergency food or just have meals on hand that can quickly be re-hydrated and eaten.
The differing Buy Now vacuum levels during the system tests would be consistent with either a door seal leak or an drain valve leak.
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.
We have a large vegetable garden, and I love that I can pick something and freeze dry it right away. I know where my food comes from and how it was treated. This gives me peace of mind in knowing I am feeding my family healthy food.
Furthermore, the modern freeze dryer systems have vacuum pumps and refrigerators which enhances the drying cycles and saves energy.
Other key factors also include energy conservation. Energy efficient freeze dryers use power saving features to meet the required energy performance standards. Helping the business not to compromise on quality, An investment in an energy efficient system helps businesses reduce operating expenses.
We can take these meals with us when we travel as well as when my son goes on Scout camp outs or activities with his friends. Buying a freeze dryer has made life a lot easier for our family.
9) The last port to insulate required the top be removed. Before I removed the top cover I replaced the side covers. This keeps the back and front panels structurally rigid. Do not remove both the side panels and top or you will have problems reassembling as things get very loose.
This electrical dryer is successful and reliable, and it offers extras you received’t locate in other equipment, like a lengthier guarantee along with a cycle which can minimize lingering pet hair. However, People bonuses come with a steeper cost tag.
