I would prefer those fittings to have internal O rings and knurled thread on ports (similar to R134a vacuum gauge sets) that do not require high torque compression fittings. Finger tight and you are good to go. You spot a leak, change the O ring and you're back in business.
5) Next up I insulated the pipes where condensation forms directly from the compressor. I used inexpensive water pipe insulation from copyright or Home Depot to wrap all exposed parts that had potential for condensation.
1. Inadequate Drying Time: If your food is not completely dry after a cycle, it may require additional time. Always check moisture levels before sealing.
What type of oil does the vacuum pump use? Harvest Right freeze dryers use food-grade vacuum pump oil, which is available for purchase. One gallon typically lasts several months with proper filtering and maintenance.
Obviously things like ice cream and marshmallows you would want to let the freeze cycle run longer. When I'm ready to start the drying cycle, I open the door, remove the insulator, and check the temperature of the food on the trays with an infrared thermometer. As long as it's below -10F I start the dry cycle. A side note for TonyC, have you ever thought about attaching a mirror to each side of the tray rack to reflect the radiant heat back in to the trays? I've looked at some mirror finish stainless on ebay, and it looks like you could do it for about $40. Not sure if it's worth a try or not. I would think it would let you get more water out in a cycle because the radiant heat wouldn't be warming the ice on the chamber walls. Just a thought....

It’s super simple, if you aren’t running an Oil Free pump (which we strongly suggest), you should change the vacuum pump’s oil every 20-30 runs (approximately once every month or two with daily use) and ensure the interior chamber as well as your trays are cleaned frequently.
And once you have resolved your issue I hope you will stay around and talk to us all about what you have been drying in your machine, etc. 1
The process involves freezing the food and then reducing the surrounding pressure to allow the frozen water in the food to sublimate directly into vapor. This method is particularly effective for fruits, vegetables, meats, and even complete meals.
AN8 male fittings are 3/4 X 16tpi. Should be able to get one that will work in this application. Also, there filters that use metric threads, might be easier to deal with.
.. Hence the vapor barrier. But once I opened it up I figured I website may as well insulate the bare ports as well, and insure that the water was diverted away from the electrics of the system. Once I sealed up the insides I noticed that the condensation on the front panel increased dramatically as the air was trapped between the plastic vapor barrier and the back of the front panel. That was when the drip rail was installed on the front of the unit.
More often than not, accidental gluten consumption means he loses about 5 pounds, which he can’t afford. Due to the potential of cross contamination, we don’t feel comfortable eating at most restaurants, which makes things tricky when we travel.
If you have a high volume lab, it’s usually a good idea to have more than one to be safe. Freeze drying ice water hash is the #1 way to dry it because it increases your production speed, enhances its color, retains more delicate terpenes, and sharply limits microbial activity.
You can leave meat covered with boiling water in the fridge overnight. For salsa, reconstitute with cold water and let sit 5 minutes.
