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.
It's awesome! I don't have a freeze dryer yet but am planning to place an order tomorrow. I am super curious how Kerry's scroll pump is holding up... eliminating the oil from the equation would make this whole thing SO much easier.
You can freeze dry things with fat and oils in it. The point isn’t to completely get rid of all the fat, but to reduce it. The reason being is for the storage process.
Truth be told, there isn’t much of a difference in terms of interface, but the Pharmaceutical models do offer a bit more customization in terms of settings. The Home Pro models however get the job done just as well and have bigger capacity for the money.
When my son goes to college in a few months, we will send him with many freeze dried meals and continue to mail them to him as needed. Most colleges don’t have safe gluten-free options, and while in an ideal world my son would be able to cook all his own food, I know that’s not practical or likely. Freeze dried meals on hand are an easy way to keep from being cross contaminated at the cafeteria!
I want my son to have great meals on Thanksgiving and Christmas, just as the rest of us do. And it’s not feasible for me to cook the entire meal for a huge crowd.
1) I installed a 3/4" wide high density closed cell foam in the gap between the front of the chamber and the back of the front panel - just what Harvest Right suggested except all the way around (the first picture shows the gap). Use your fingers to push it into place. It needs to be tight against the inside panel. Know More I then installed a vapor barrier around the entire FDer chamber. I used 7mil plastic and clear packing tape.
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.
Colin Arnason Albert was very responsive and answered any questions or concerns I had. Great product and I’m enjoying using it.
Freeze drying preserves fresh fruits and vegetables Freeze drying is a great way to preserve food for short term or long term storage, up to 25 years.
Not all of us are technical experts (the 'not' category includes me) but I hope someone who can help you will come along soon.
Run full system test with no food in chamber (results, 630 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)
Harvest Right’s lyophilizer/freeze dryer is the perfect addition to any laboratory. The scientific freeze dryer can be Scientific Pro Freeze Dryer for sale Canada completely customized with your preferred processes.
