I have no 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 only downside is that the interior is now so cold that defrost time has doubled! I use a large high volume fan to defrost the unit, not the heat trays. It used to be a 15 minute job, now it is closer to 30 minutes.
I’d recommend that anyone stick with buying any freeze-dryer or heavy equipment directly from the manufacturer. And if you’re ready to shop for a Harvest Right, you can use this link to shop current sales.
So, while it might be tempting to stuff just as much as you may onto a tray, an arranged tactic making use of these applications will produce the best freeze dried foods, batch immediately after batch.
I would prefer those fittings to have internal Este 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.
They come out as dry and hard as lumber. So, if you try website to freeze dry a steak or roast, expect to break a tooth eating it.
One of the many joys of having a working freezer is the potential that it holds. While cooking may not be everyone’s forte, saving time usually is, and this is one of the benefits a freezer affords. By scheduling particular days and reserving them exclusively for the preparation of a week’s worth of meals, you’ll save not only a significant amount of money, but time.
A bit of background on me - I used to work in a sold state fabrication lab (university research lab) and had a lot of hands-on work with ultra-high vacuum equipment. The pumping we do for freeze drying was what was required to just start
This method of shopping is usually considered a bit outdated, but you can still get all the necessary information about freeze dryers on the phone by talking to a company salesman.
Karla Abreu says: 2 years ago I just think pressure canning is the easiest way to preserve food and know it is totally sterile. And it is relatively easy
This type of website can’t hurt when buying something minor, like a piece of clothing, but it’d be smart to steer clear from them when buying expensive equipment.
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.
However, we have to point out that finding information online is much easier, as it’s all available on company websites. All you have to do is click.
19.7k Location:Ontario, Canada Posted January 25, 2016 So a couple of months ago (when the weather was still warm) Alleguede has his assistant drop off some raspberries that he wanted me to freeze dry for him. Since they were IQF raspberries I assumed that they would be individual - but apparently when you leave them in the trunk of your car long enough to thaw, then put them back in the freezer - then take a couple of days to get them over to me - they are no longer going to resemble individual raspberries.
