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 Este ring and you're back in business.
Mylar bags keep food fresh for years The enemies to freeze dried food are moisture, oxygen, and light. Ideally, the food should be stored in a mylar bag with an oxygen absorber. The bag should be heat sealed to keep air from getting in. For best results, use a mylar bag 7 millimeters thick.
In these tough financial times, you need a company you can trust with stewardship of your life’s savings. We recommend self-directed IRAs backed by physical precious metals provided by Genesis, a faith-driven gold and silver company.
Over night the FDer warmed up and the next morning we had a massive puddle under it - running off the counter onto the floor. I cleaned up the mess, but the next day the puddle was even bigger. On the 3rd day it was back again just as large even though I left a large towel under the FDer.
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.

I did wonder though, since this is gravity flow and not pressure driven as on a car, if having the filter mounted horizontally might result in using only "half" the filter, as the oil would tend to travel through the low side of the filter -- although in practice, I suppose, as more info the filter material gets plugged it would force the fluid level higher.
This includes setting as many as five different shelf temperatures, thus allowing the material to dry in phases, at different temperatures. For instance, you might have the material begin drying at 10ºF and increase the temperature in phases until the ultimate final dry temperature is 70ºF.

adding insulation on the 3 ports on the chamber (One time thing - the drain and vacuum ports are very easy to get to)
Unlike other conventional methods of drying, the original structure of the food is preserved with freeze-drying which ensures better quality for the consumers.
The system’s shelf heaters and adjustable vacuum pressure ensure controlled sublimation during the primary drying cycle, preserving your materials at peak quality.
Regular maintenance includes cleaning the vacuum pump and ensuring proper drainage after each use; refer to the manufacturer's guidelines for specific maintenance tips.
The system records and maintains a log of the pressure and temperature during all parts of the freeze-dry cycle.
