Jeanine L. Albert was quick to respond to my inquiry about the delivery of our harvest right freeze dryer. I hope companies will have more “Albert” in their team for the satisfaction of their customers! Thank you so much Trimleaf for helping us purchase this great product! Team Albert here!

Removing the ice from between the chamber wall and the insulation (hopefully will never have to do this again)

The best choice I ever made when it comes to long-term storage food is getting a freeze dryer. I didn’t always think that. It was far more work than I imagined and the maintenance on the machine is annoying when it needs it.

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.

April 22, 2025 by Lily James Freeze-drying, also known as lyophilization, is one of the most important processes in the food industry and the pharmacy sector, as it allows for long-term storage of a product without losing its value. Currently, this method is extensively employed for the preservation of active pharmaceutical ingredients, biologics, and food products as moisture is extracted without deteriorating its quality.

How does freeze drying work? To put it simply, it freezes the food then goes through a sublimation process where it dries the food.

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

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)

Drying things out played a roll as well as the added insulation. We had 3.5 weeks of constant rain here in central NC with humidity over 95% and temps near 95F in the beginning and tapering down to 80F by the end of the rain. The condensation on the front panel around the seal had water running down the front of the Freeze Dryer constantly during the entire cycle, not just the freeze cycle. I initially went into the FDer to simply stop the humdity from reaching the outer chamber shell and freezing.

“Astronaut” ice cream is a fun treat to make and is so easy. Just scoop ice cream onto the trays and freeze before processing.

You will be addicted once you realize how much you can freeze dry, how easy it is and how much you can preserve for your household in a short amount of time.

Hey there, fellow self-reliant folks! If you're all about preparedness and want to take your food preservation game to the next level, you've probably considered getting yourself a freeze dryer. But let's be honest – freeze dryers aren't exactly known for being wallet-friendly.

Control of the amount of time a material is held at the ultimate freeze temperature before the drying cycle is started.

I, too, have noticed a website significant difference when I defrost mid-cycle. I do that routinely now. I carefully use a heat gun to "shock" the surface of the ice, moving back and forth across it fairly swiftly, which causes it to crack and separate somewhat from the cylinder.
