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.
Mylar bags keep food fresh for years The enemies to freeze dried food are moisture, oxygen, and light. Ideally, the food should be stored in a mylar bag with an oxygen absorber. The bag should be heat sealed to keep air from getting in. For best results, use a mylar bag 7 millimeters thick.
I have no adverse vacuum performance change with the catch can in place. It just catches any oil. I still smell oil vapor when the pump first starts up, but not nearly as much. I've only emptied the can once or twice since I've had it installed. I slightly over filled the pump and it blew out into the can, then ran it with the FDer valve open for a few minutes. Nothing got past the can. I used the outside port as IN and the middle one as out. I did take the port off and the longer one should be the inlet port. It's not a great deal longer.

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.
Unlike canning or dehydrating, freeze drying retains 97 percent of the food’s nutrients. Freeze dried food also tastes more like fresh food than canned or dehydrated foods.
Freeze drying is a dehydration process that removes moisture from food while preserving its structure and nutritional value by freezing it first and then creating a vacuum around it.
I think a community-built troubleshooting manual is a great idea. These machines are simple in some ways, and more complex in others, and having a lot of eyes on the problem is always good.
The unit can also connect to and communicate the freeze dryer cycle data to a nearby PC through an Shop Now ethernet cable.
1. Capacity Needs: Assess how much food you plan to freeze dry at once. Smaller models are suitable for individual use, while larger models are better for families or community storage.
Pre-frozen food takes less time to process since the machine doesn’t have to completely freeze the food. Your climate (humidity and temperature) can also affect the cycle length. My average load takes around 24 hours, but it can be significantly longer.
So, while it might be tempting to stuff just as much as you may onto a tray, an arranged tactic making use of these applications will produce the best freeze dried foods, batch immediately after batch.
This is why so many people are buying their own freeze dryers to use at home. The market is essentially cornered by Harvest Right, which isn’t a bad thing since their quality and customer service are both superb.
As I mentioned before, freeze dryers are an investment. They're an investment because of all the benefits they bring to you and your self-reliance.
You can choose to season meat either before or after the freeze drying process. I prefer to season cooked meats before processing and leave raw meat unseasoned. Then the meat can be seasoned later before it’s cooked.
