Long ago. and B. I don't have the test equipment I did then. I guess what I'm saying is don't be afraid to get too technical with me in your answers. What I wouldn't give for a helium leak detector right now...
4) I made a plastic shield to protect the main circuit board of the FDer. it simply slides into place and protects the top and both sides of the board from condensation.
The best choice I ever made when it comes to long-term storage food is getting a freeze dryer. I didn’t always think that. It was far more work than I imagined and the maintenance on the machine is annoying when it needs it.
5. Maintenance: Understand the maintenance requirements of the machine. Some units require more frequent servicing than others.
•Control of the amount of time a material is held at the ultimate freeze temperature before the drying cycle is started.
With various options available in terms of size and capacity, it's crucial to assess your needs before making a decision.
Freeze dried foods are delicious by themselves or powdered and used in smoothies or baked goods. I have found I can freeze dry apple slices, powder them, and add a little water to make applesauce. It’s a lot easier than making applesauce in a traditional way.
The initial cost can be high, they require adequate space and power supply; also, they can be noisy during operation.
A couple of other points: There are obvious and easy improvements that could be made, such as using a container with a dispensing faucet (think of a lemonade jar, for example). Also, for the technically savvy, auto-mechanic-type person who may be wondering about it, there is an anti-backflow seal that has to be removed from the oil filter, but that can be removed by cutting through it and pulling it out with needle nose pliers, which is easily done.
12 Posted September 16, 2015 You've given me harvest right Canada an idea. I have the parts at the shop to use an actual filter head and a spin on filter. I could have a bracket laser cut and powder-coated that would hold the filter/head assembly horizontal which would allow it to completely drain and the outside of the filter would stay clean.

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.
Forgive me for the extremely long post but I thought other southerners may also face this problem and could use this information.
and this piece was placed on the vacuum hose fitting. I can still remove the panel without removing the hose to clean the coils. Simply remove the screws and slide the panel down the vacuum hose a few inches.
