Another advantage of buying a Harvest Right freeze dryer on their website is all the information about the dryer itself. It’s highly unlikely that an employee at Home Depot knows more about freeze dryers than the FAQ and blog sections of Harvest Right’s website, which their engineers write.

Reattached hose and ran another full system test (results, 750 mTorr lowest steady reading - looking through the oil level window, some bubbling seen in oil even after an hour of pumpdown - some "air" noises from pump)

the "real" vacuum pumps on those machines, with ultimate vacuum levels a few more demial places over. I've chased many a leak in my time,but it was: A.

It failed to reduce the moisture in the oil... I'm in the process of modifying it to catch and suspend the moisture in the container long enough for desiccant beads to absorb the water. The air flow comes into the inlet, down the central pipe to the bottom of the screen and filters up through the beads and out the top. I know this was like forever ago, but I thought I would respond anyway. I haven't been on much in a while, I only run my freeze dryer in the winter. So I think you'll find it's a lot harder to remove water vapor from a vacuum than just using desiccant, as the vacuum will just pull the water out of the desiccant.

It's awesome! I don't have a freeze dryer yet but am planning to place an order tomorrow. I am super curious how Kerry's scroll pump is holding up... eliminating the oil from the equation would make this whole thing SO much easier.

Learn how to safely preserve berries through a variety of methods, such as canning, freezing and other methods.

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.

This method of shopping is usually considered a bit outdated, but you can still get all the necessary information about freeze dryers on the phone by talking to a company salesman.

Did you know Shop Now that there are many ways to preserve your chiles? This resource offers the resources you need to learn how to freeze, can, dry, and store your chiles!

My husband has been contemplating cost effective alternative ways to get oil-less vacuum happening... what would the specs needed be, since I don't have a pump to look at. Hopefully I asked that in a way that makes sense.

We have to face one hard fact when shopping for home freeze dryers. That fact is, unlike many other purchases, freeze dryers aren't cheap. However, unlike many other purchases, a freeze dryer can provide a lifetime of cost savings that ultimately pay for itself.

I found out the hard way about the anti-drainback seal when I first tried the filter and got... nothing. I did do some research afterward and learned, as you point out, that there are some filters than don't use the seal but by then I was committed. Fortunately, it wasn't all that hard to remove it, but definitely better not to have to.

You can have electric or gas grills. Gas grills deliver higher and faster heat. They will also cook more evenly than electric. Electric grills are typically cheaper and will have more functions. However, electric grills heat slowly and can be more difficult to maintain.
