I honestly think putting a thermometer inside the unit is an excellent idea. I sent the following note off to Harvest Right Support in an effort to gain a little better understanding of the process.
After a few years of research, I finally decided to purchase a freeze dryer. It was one of the best purchases I have ever made. The only regret I have is that I didn’t buy one sooner.
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.

Regular maintenance includes cleaning the lint filters, inspecting and cleaning heating elements, checking for any blockages in vents, and ensuring all moving parts are lubricated. Follow the manufacturer's maintenance guidelines for specific intervals.
Michelle Dubrule I recently received my new freeze dryer in a timely manner and I was pleased with the excellent service. The company kept me informed about any expected delays during transport, which I greatly appreciated.
•The shelf heaters can be set to automatically control the rate of sublimation during the primary drying cycle. Through this process, the Shop Now unit has control of the attendant vacuum pressure.
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.
Isolated pump by capping the stack (no meter to measure pressure, but no bubbling after a very short pumpdown - pump sounded normal for a high vacuum situation)
We love to get together with family during the holidays. Our family is massive and my son is the only one who is gluten-free. Although our family members are sympathetic and want to be accommodating, they don’t always realize that gluten is in found in more than just bread.
Without an pump isolation valve I would expect some air to flow back into the chamber through the pump resulting in the steady rise you witnessed. I saw the same phenomenon before I installed an isolation valve on my pump.

How are freeze dryers shipped? Delivery is via FedEx Freight for most urban addresses, while rural locations may use a last-mile delivery service. All deliveries include curbside service and require a physical address to schedule delivery appointments.
Harvest Right’s lyophilizer/freeze dryer is the perfect addition to any laboratory. The scientific freeze dryer can be completely customized with your preferred processes.
The food options we had there were extremely limited and full of preservatives. To counter that, my buddy Lance went in with family members on the purchase of a freeze dryer for home use.
