You’ll have to decide whether the pros outweigh the cons. For me personally, non-e of the cons outweighed the pros. The high price tag is an investment in my ability to preserve food for long periods of time for me and my family without relying on others. The noise doesn’t bother any of us and it’s like white noise.
Reattached hose and ran another full system test (results, 750 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)
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.
When isolated, the pump seems to behave well. Short of putting a meter on the pump, my impression is that it is operating properly. I'm considering investing in a good meter to verify that it is reaching a good ultimate vacuum.
It freezes the product and lowers pressure to remove ice by sublimation. Sublimation is the transition of a substance directly from the solid to the gas phase without passing through the liquid phase.
•The shelf heaters can be set to automatically control the rate of sublimation during the primary drying cycle. Through this process, the unit has control of the attendant vacuum website pressure.

We will still run batches of strawberries or zucchini when there’s nothing else to go in but for the most part we stick to the higher-end foods.
Another emerging trend is the production of environmentally friendly and energy saving freeze dryers. Manufacturers are trying to lower the carbon footprint of their machines by introducing more energy efficient and sustainable devices.
Not all of us are technical experts (the 'not' category includes me) but I hope someone who can help you will come along soon.
Nicky Risk Thank 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.
The next way to save money is to watch Harvest Right's website for seasonal sales and promotions. Sometimes, patience pays off in the form of significant discounts.
