I would prefer those fittings to have internal Este rings and knurled thread on ports (similar to R134a vacuum gauge sets) that do not require high torque compression fittings. Finger tight and you are good to go. You spot a leak, change the Este ring and you're back in business.
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.
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:
In fact, my son’s friends often comment that they wish they could have his freeze dried meals rather than whatever they are eating!
By this point, most of my son’s friends know about his dietary restrictions and it doesn’t bother them. My son takes rehydrated freeze dried meals to school banquets and to other social gatherings.
Adopting such technologies puts these businesses in a better position to meet regulatory standards and makes them more viable in the market.
Hopefully more info I said that in a way that makes sense! As well, does it matter which port is used as "in" and which as "out"?
The system records and maintains a log of the pressure and temperature during all parts of the freeze-dry cycle.
Control of the amount of time a material is held at the ultimate freeze more info temperature before the drying cycle is started.
I personally have a medium Harvest Right Freeze Dryer and love it. I actually wish I had gotten the large! But for our family of 4 (almost 5), it’s a perfect fit, we have it running constantly and fill bins full of homemade freeze dried food.
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.
The system’s shelf heaters and adjustable vacuum pressure ensure controlled sublimation during the primary drying cycle, preserving your materials at peak quality.
Freeze drying has been proven essential throughout many industries where stability of the product is of utmost importance. The pharmaceutical field greatly benefits from freeze drying as medicines are rendered impotent for long durations without losing their potency, while in the food industry, freeze drying prevents decay of food without compromising on taste or texture.
Unfortunately, freeze-dried food can often be very expensive. We’ve seen this first hand as the only company that sells both frozen beef boxes to store in the freezer for up to a year as well as freeze-dried beef cubes to store in the closet for over a decade.
