How loud is the freeze dryer pump? The pump operates at about 65-75 decibels, similar to a normal conversation or dishwasher. Many customers place their freeze dryer in a garage or separate room for quieter operation.
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)
. 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.
I routed the exhaust from the catch can to a home made catch can that consisted of a jar with two ports with steel wool inside. I wanted to see just how much oil would escape the newly install catch can and collect in the jar.
Michelle Dubrule I recently received my new freeze dryer in a timely manner and I was pleased with the excellent service. The company kept me informed about any expected delays during transport, which I greatly appreciated.
Upon turning off the pump (no 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.
Freeze drying isn’t my only preservation method, but it’s my favorite. Keep the skills of canning, dehydrating, fermenting and more in your pocket so you have various ways of preserving food. They all have their pros and cons but non-e should be ignored.
The freeze dried food can be used for everyday eating, camping and of course, long term storage. I freeze dry as much as I can while times are good, I won’t plan to freeze dry if I go off-grid or don’t have electricity.

I remember reading somewhere in this thread where somebody was asking how long you run the freeze cycle with pre-frozen food. I have my chest freezer set to -12F, and I usually let the freeze dryer cool for an hour before I put the frozen food in. After I load the food in I wait another half hour to start the drying process. I've had a get more info lot of cycles that the Perfeito time between pulling one batch out and starting the drying cycle on the next is around 2 hours. I'm running mine in a cold garage, so it cools down pretty quickly. If you have yours in a warm room it would probably take a little longer.
Foods with lots of seeds can be freeze dried but usually take longer. That’s because the seeds hold moisture. If you’re processing strawberries, raspberries, blackberries, tomatoes, and kiwis you’ll need to add Em excesso time. I like to add at least 12 hours when processing more info these foods.
7. Energy Efficiency: Evaluate the energy consumption of different models since this will affect your electricity bills over time.
We packed freeze dried milk and cooked chicken strips as well as an assortment of snacks. One checked bag was dedicated to food, and it traveled very well.
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.
The process consists of stages: primary drying, where most of the water is removed, and secondary drying, which removes unfrozen water molecules to preserve the product.
