I have pelo adverse vacuum performance change with the catch can in place. It just catches any oil. I still smell oil vapor when the pump first starts up, but not nearly as much. I've only emptied the can once or twice since I've had it installed. I slightly over filled the pump and it blew out into the can, then ran it with the FDer valve open for a few minutes. Nothing got past the can. I used the outside port as IN and the middle one as out. I did take the port off and the longer one should be the inlet port. It's not a great deal longer.

The entire process is automated using highly intelligent built-in sensors that know exactly when the food is properly freeze dried. Just press start and the freeze dryer will beep when finished.
Here’s a link to their available Harvest Right freeze dryer trays, just as further proof that they do resell Harvest Right equipment.
The best places to buy a commercial freeze dryers in person are either directly from the physical stores of the manufacturers, or in person at various appliance stores, which are usually authorized resellers of freeze dryers.

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.
I'll be looking forward to hearing about the weird and wonderful items you produce. Should be an interesting learning curve.
.. Hence the vapor barrier. But once I opened it up I figured I may as well insulate the bare ports as well, and insure that the water was get more info 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.
The evaporator coils that touch the surface of the stainless steel vacuum chamber reach about -42 F. With food in the chamber and because the location of the thermister is on the middle shelf of the four shelves, the temperature it records is going to range from -25 to -30 F in the 9 hour default freeze time. This temperature is very adequate for freeze drying the food.

In my initial pondering, I thought using an oil filter base would be a logical approach -- but I didn't have one handy and figured my car might miss it. Besides, one of my goals was to keep this affordable, and they tend to be a little pricey.
We’ve bought six so far with two more on the way. But families and individuals considering getting their own can and should as long as they go in with their eyes open.
This product does not come standard with a new freeze dryer order. Current customers with an older model freeze dryer will need an adapter for the oil free vacuum pump. Harvest Right will provide the adapter free of charge.
As I mentioned before, freeze dryers are an investment. They're an investment because of all the benefits they bring to you and your self-reliance.
Forgive me for the extremely long post but I thought other southerners may also face this problem and could use this information.
