How you want to run your electrical is up to you, but there’s nothing worse than having your freeze dryer trip a breaker switch (especially when you’re not there). Installing or using an Em excesso dedicated 20 amp for this model and the Large Pharmaceutical unit as well is strongly suggested.
Never allowing the unit to heat up to ambient temps - Quickly removing the ice from the chamber and starting the next cycle while the chamber unit is still very cold.

The only way I know to filter the water vapor out would be a cold trap. They usually use liquid nitrogen or dry ice to keep the temperature low enough that all the water condenses out. Obviously you would need a supply of the liquid nitrogen or dry ice that would probably not be cost effective for most of us. The other option to get that cold would be to use a cryocooler and build a cold trap around it. It could be done, but would be pretty expensive. I've been watching some electronics on ebay that have cryocoolers in them, but the cheapest I've seen is around $600. Still not a cheap option, but you wouldn't need dry ice or liquid nitrogen to feed it.
Ideal vacuum pressure and drying temperature is maintained for each material and preserves freshness and potency
And once you have resolved your issue I hope you will stay around and talk to us all about what you have been drying in your machine, etc. 1
Granted, most of that time is the freeze dryer doing all the work, but the process is not without effort. Once the food is ready it must be put into appropriate containers with oxygen absorbers and sealed properly so they can last.
Gas appliances are much more powerful, and better suited for large scale commercial operations. The gas appliances heat up faster and are typically more durable. For preparing meals, gas ranges are the better choice for chefs.
Unlike laboratory freeze dryers, they usually don’t need drying at such high speeds, which is the biggest difference between the two.
I, too, have noticed a significant difference when I defrost mid-cycle. I do that routinely now. I carefully use a heat gun to "shock" the surface of the ice, moving back and forth across it fairly swiftly, which causes it to crack and separate somewhat from the cylinder.
I’ve seen Walmart offering freeze dryers online, at least. Here’s the link to their freeze dryers.
One idea I that I had was to freeze-dry sorbet. Sort of a twist on astronaut ice cream. I've had freeze dried strawberries, and those have a nice crunchy texture.
In many cases, people are in need of a fridge repaired but are too afraid of the potential cost of having to buy a new one; as a result, they avoid cooking for days at a time and dabble in the bad habit of ordering take incessantly.
