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 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 Em excesso 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.

Question for you: I'm impressed by the shortening of cycle times. Obviously some of that is from the improvement in insulation on the lines, etc., but I'm wondering how much more info of it might be from "drying out" of the insulation and outer walls of the freeze drying chamber.

I removed the side covers and found the water dripping from the chamber insulation. I called up HarvestRight to ask for ideas on how to avoid this in the future.

Now that you understand the conditions, you can better understand what happened when we finally turned off our FDer after an extended use in these conditions.

Pharmaceutical freeze dryers are more advanced 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.

Most other methods for extracting water also destroy enzymes and terpenes due to heat being used in the extraction process. Because freeze drying does not use heat during operation, the enzymes and terpenes in freeze dried products are not destroyed.

When buying from resellers, those terms may change as they’re affected by the relationship between the manufacturer and the reseller.

19.7k Location:Ontario, Canada Posted January 25, 2016 So a couple of months ago (when the weather was still warm) Alleguede has his assistant drop off some raspberries that he wanted me to freeze dry for him. Since they were IQF raspberries I assumed that they would be individual - but apparently when you leave them in the trunk of your car long enough to thaw, then put them back in the freezer - then take a couple of days to get them over to me - they are pelo longer going to resemble individual raspberries.
