- Anything with too high a fat content may give some problems because the oils or fat will not evaporate, only the water will.

Hence, the Premier Pump is especially not affected by warm, ambient conditions. When temperatures rise, it will pull a vacuum far better than the Standard Pump. The Premier Pump is just not affected by outside heat. It pulls the same deep vacuum even when it is in a warm environment.

Long ago. and B. I don't have the test equipment I did then. I guess what I'm saying is don't be afraid to get too technical with me in your answers. What I wouldn't give for a helium leak detector right now...

These commercial freezers are also a must-have for commercial kitchens that need to freeze very large containers or boxes that cannot fit inside of a conventional freezer. You can purchase several different sizes of walk-in freezers. They’re custom-made to the kind of space you have.

And therein lies the cons to buying a freeze dryer. It takes time to make them cost effective. Depending on humidity in your area, a single run can take up to two days to complete.

The current and emerging food crises in the United States have millions of Americans very concerned about the future. From supply chain shenanigans to food processing plants “inexplicably” being compromised to bird flu decimating the poultry industry, it’s no wonder there has been a sharp rise in the “prepper” food industry.

1) I installed a 3/4" wide high density closed cell foam in the gap between the front of the chamber and the back of the front panel - just what Harvest Right suggested except all the way around (the first picture shows the gap). Use your fingers to push it into place. It needs to be tight against the inside panel. I then installed a vapor barrier around the entire FDer chamber. I used 7mil plastic and clear packing tape.

This method of food preservation causes little damage to the nutritional value of the food being preserved compared to other methods that use higher temperatures, such as canning or dehydration.

Pharmaceutical freeze dryers are more advanced more info than everyday commercial freeze dryers, which is why they’re more expensive. Additionally, they’re more difficult to find as they’re aimed at a smaller market and there’s likely liability insurance built into the pricing models.

01%, effectively preserve these packaged foods without the need for preservatives or additives and without the need for vacuum sealing.

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.

Most pharmaceutical or laboratory-grade freeze-dryers have to be purchased from licensed manufacturers. These sales often need to be done over the phone or in person with an equipment salesman, though those can be found online. Some options are also available online at places like Amazon.
