There are 3 ports on the chamber that I made slits in the plastic to get around and taped them up once around them. Do not tape to the insulation. Tape only to the vapor barrier plastic. It doesn't take long, just be careful. After the plastic is in place and secure around the chamber I sealed the plastic to the back of the front and back panels using the packing tape. All the way around the front and back of the chamber to completely seal the chamber from outside air and humidity.
After the 3rd cycle I had hit my 20 cycle oil limit so it was time to change the oil. This time I took the time to add a flush port to my pump. When I replaced the plumbing with larger diameter brass and a cutoff valve I did not think to add the oil flush out port.
Our electricity was very high when we had it in AK because our electric company charged a lot, but in Texas, it’s very cheap to run. I don’t mind that I can’t freeze dry some things, as most of the things that you can’t freeze dry, you can purchase commercially or they shelf stable as is. For instance, I don’t freeze dry butter, but I do buy powdered butter. Oh, here’s one more potential con:
Many times, you can still freeze dry something if you mix it in. For instance, if there’s a meal that has butter in Know More it, it’s fine to freeze dry. It may just reduce the shelf life a little. So instead of 25 year shelf life, it might have a 10 year shelf life.
•Control of the amount of time a material is held at the ultimate freeze temperature before the drying cycle is started.
Ice is then turned into vapor by applying heat while simultaneously lowering the surrounding pressure during sublimation. During the remaining phase, moisture that is loosely bound is removed in order to bring about sufficient stability for the product to be stored for longer periods of time.
You can count on me sticking around to talk about the food side of things! My wife looked at me a little oddly when I got the freeze dryer, but now she's a fan too. I'm discovering things that it can do that I hadn't expected, such as making low carb snacks.
The system records and maintains a log of the pressure and temperature during all parts of the freeze-dry cycle.
A bit of background on me - I used to work in a sold state fabrication lab (university research lab) and had a lot of hands-on work with ultra-high vacuum equipment. The pumping we do for freeze drying was what was required to just start
Furthermore, the modern freeze dryer systems have vacuum pumps and refrigerators which enhances the drying cycles and saves energy.
In times of crisis or natural disasters, having a stash of freeze-dried meals can be a lifesaver. Your family's safety and well-being are priceless. Not only does a freeze dryer set you up to survive, it lets you control the quality and content of your emergency food supply.
Nicky Risk Thank more info you so much to Albert for all your help and advice on helping me choose the best Harvest Right for my family. We are super excited to experiment with our freeze dryer.
Depending on how you want to use freeze dried food, it doesn’t have to be reconstituted. There are some freeze dried foods I like to powder in my blender or food processor and then add to other foods. These powders can be used in smoothies, soups, and baked goods.
The industry standard machine for drying ice water hash at commercial operations that need serious throughput
