I am looking for a more defined "heuristic" curve based upon the internal temperature. I am sure that your engineers probably have tables for such things. I also know that different foods freeze at different rates, that is why I am asking for a heuristic answer.

The food and pharmaceutical industries crucially rely on freeze drying for the long-term storage of products. This method enables businesses to preserve product quality, extend shelf life, and improve stability.

It makes the processing time faster, which means less wear on the machine. If I am preparing fruit, I typically slice it and put it on a baking sheet.

This new Industrial Pump rarely needs to have the oil changed or filtered. The pump has a gas ballast feature that makes it so water does not stay in the oil. Because of this, the oil in the pump will be pristine and clear, even after 30 or more batches.

And once you have resolved your issue I hope you will stay around and talk to us all about what you have been drying in your machine, etc.

•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 pressure.

The differing vacuum levels during the system tests would be consistent with either a door seal leak or an drain valve leak.

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 more info 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.

I freeze dry right now so I can have as much preserved food as possible. For me, it’s a lot cheaper in the long run, even with the initial investment and run time.

Based upon your work experience you probably know more about vacuum pumps than most of us. Chasing a vacuum leak can be frustratingly difficult.

- Complete Meals: Casseroles and soups can also be freeze-dried for convenient meal prep options later on.

Run full system test with pelo food in chamber (results, 630 mTorr lowest Know More steady reading - looking through the oil level window, some bubbling seen in oil even after an hour of pumpdown - some "air" noises from pump)

Have an understanding of which kind of food pretreatment is needed to use the device. To ensure the freeze-drying approach is productive, you’ll must understand how to get ready food.

You can choose to season meat either before or after the freeze drying process. I prefer to season cooked meats before processing and leave raw meat unseasoned. Then the meat can be seasoned later before it’s cooked.
