In any sector – whether biotech, food production, or pharma – adopting high-capacity freeze dryers helps improve efficiency and business sustainability while meeting regulatory obligations.
We preserve our favorite foods, which means I know my family will eat them when it’s time to break them out, whether that’s for a camp out, family vacation, or the apocalypse.
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. For instance, I don’t freeze dry butter, but I do buy powdered butter. Oh, here’s one more potential con:
the "real" vacuum pumps on those machines, with ultimate vacuum levels a few more demial places over. I've chased many a leak in my time,but it was: A.
While I had the unit apart to replace the display I decided to correct the water condensation problem. If you find yourself using your FDer in the same conditons as we do you may want to consider modifying your FDer to keep the condensation from your FDer control circuit and display cards. Here are the steps that I followed to minimize what the NC high humidity climate does to my FDer.
It takes slightly extended to dry than our other picks, and it lacks a speed-dry option, but it surely gets the job accomplished and fees various hundred dollars under very similar dryers.
Trust the machine. It will let you know when it thinks the food is done. Once the cycle has finished, you can check the food to see if it is completely done. If so, you can remove it from the machine and package it. If the food isn’t done, you can add time.
Hence, the Industrial Pump is especially not affected by warm, ambient conditions. When temperatures rise, it will pull a vacuum far better than the Standard Pump. The Industrial Pump is just not affected by outside heat. It pulls the same deep vacuum even when it is in a warm environment.
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.
Foods with lots of seeds can be freeze dried but usually take longer. That’s because the seeds hold moisture. If you’re processing strawberries, raspberries, blackberries, tomatoes, and kiwis you’ll need to add extra time. I like to add at least 12 hours when processing these foods.
It appears that the ice build up inside the chamber sublimates as well as the Know More ice in the food. Eliminate the ice and the process is faster, and less water ends up in your oil.
The only way I know to filter the water vapor out would be a cold trap. They usually use liquid nitrogen or dry ice to keep the temperature low enough that all the water condenses out. Obviously you would need a supply of the liquid nitrogen or dry ice that would probably not be cost effective for most of us. The other option to get that cold would be to use a cryocooler and build a cold trap around it. It could be done, but would be pretty expensive. I've been watching some electronics on ebay that have cryocoolers in them, but the cheapest I've seen is around $600. Still get more info not a cheap option, but you wouldn't need dry ice or liquid nitrogen to feed it.
Monitoring the FDer internal temps and once I see -40F I start the dry cycle, except for high sugar content food which I give an extra hour. I'm still experimenting with Ice cream and a few fruits to determine optimal freeze time to get the best results. The cooling cycle ends up much shorter.
And, as I write that, the “more is better” side of my brain is freaking out. After all, bigger means better, right? Not always, but read on to learn my thoughts on why the small freeze dryer may be the way to go.
