Some pitfalls when freeze drying…
This last freeze dryer run has been a slog. bad thing is that every single issue has been our fault. Here’s what we’ve encountered. Over loaded trays and a drain valve left open, so a vacuum couldn’t be set. An over heated pump, because we had to run extra dry time, because of the over loaded trays. Extracting a tray that was encased in ice without ruining the food. A pump that was inadvertently turned off when cleaning it during troubleshooting of the previous events, so again, it was unable to set a vacuum. This was the first run since we got the dryer up and running after it being down for repairs for 2 months. We haven’t had a full run that went without a hitch for over 4 months. I’d like to get just one that worked from start to finished packaging. Well, the good news is that for the foreseeable future, there is always next time.
If you have a freeze dryer, have you had any self inflicted problems?
