Before buying a freeze dryer, perhaps research to find out more about the downside of the machine; some people have problems with their machine and it's big and heavy and hard to return!
When trying to decide what to freeze dry you can start by asking why.
Start by asking yourself this question. Why are you freeze drying food? Knowing this should help you decide what you should freeze dry first.
I'm freeze drying because:
Just to freeze dry leftovers?
You want to make your own food for camping/backpacking?
For if/when the SHTF?
For a short term emergency?
You have your own garden and want to freeze dry the food?
You love Costco but don't have a family of 6?
You are good at finding the food sales but only have 1 freezer?
When you cook homemade chili just for yourself you make 10 gallons? Because you have 3 full freezers and are worried about power outages?
If I knew then what I know now, I would have freeze dried things in a different order. Or maybe not, because I started freeze drying because we had 3 full freezers, I was thinking of getting another one, and I decided I should buy a walk-in freezer instead. I started looking into walk-ins and realized they were expensive to buy (even used ones) AND expensive to own and operate. Then I found out Harvest Right was making home sized freeze dryers. One of my first thoughts was "I like Mountain House!" I have used their food for backpacking almost 45 years and we even kept some in our travel trailer, for just in case.
Freeze dried food will stay fresh for many years and be ready and waiting when you need it.
We do videos showing how we are using our Harvest Right Freeze Dryer to freeze dry food for long term storage. (We have the medium size machine that we got in August of 2017) We talk about how to load and unload the freeze dryer, how to know if the food is dry, is it better to freeze dry raw food or cooked food, and do a few taste tests. Freeze dried food is also great for prepping or just for camping and snacking!

I just bought the new small pro (4 shelves) from Harvest Right a couple months ago and have been running batches continuously. I found you after my purchase. But my FD came with this pump as well as their impulse sealer. I watched your video on replacing your sister's teflon tape, and how you were impressed with how the Harvest Right sealer was made, and now with watching this video and you impressed with this pump, I'm so happy with my purchase!!! I'm on run 25 and the oil in the window is so clear clean! Thank you for your videos - I'm going to start watching all yours. Right now I'm starting to think of meals, and too, Christmas presents of FDed things!
Thanks for watching and commenting!
It is stunning how clean the oil has stayed with this pump.
That really is amazing how clear it is
I have that same pump. I haven't changed the oil since I've gotten in and I've been worried about it. I do plan on changing it once this summer heat finally breaks. Glad to hear how clean this runs.
brother i know running that fan over the pumps to make them run cooler seams like a good thing but those pumps need to run at a high temp that is how they remove water from the oil
Thanks.
Yes, I know. It's not like we're making it cold! Most electric motors run more efficiently and last longer when kept under 160ºf. Very high temperatures also degrade the oil faster, leading to less effective vacuum and the need to change the oil more frequently.
Properly run, no water/moisture should ever make it to the pump. The cold trap should be stopping/capturing all of the water, and on her machine, the way we run it, it does. Her pump has never had a single drop of water.
I have a much older machine, I know what moisture in the oil looks like.
I'm not trying to convince anyone of anything, I'm just trying to show what I do, try to tell why I'm doing it, show what's been working year after year, and show resources when I can.
👍👍👍👍👍
Do you have a vodeo on building a recirculation system ?
Sorry, I've never made a how-to video about building the filter system. These videos do show it in more detail, perhaps they will help. I'll answer an question I can.

it is an informative video , i appreciate your efforts
i thank you in advance if you can explain what inside the machine to know more about how it work, specially the cooling cycle
Thanks. Good idea!
Is there foil around the black seal? I am new to freeze drying. Mine has not been used yet. Trying to learn all I can.
It's purpose is to insulate the seal.
The machines don't _need_ the seal insulation or the door disc we add, but for us it's a useful addition because of two related things: condensation and heat transfer. First, while it's cooling, but before the vacuum pump starts, it helps with heat transfer. Second, because I often (very often!) don't get to the machine right away when it finishes, it just sit there chilling. Sometimes it waits 12 hours or more. Very chill, -40 chill. By the time I get around to it, without the front disc and seal insulation, the entire door and seal would be covered with condensation, both liquid and frozen. And then it melts and makes a mess. For people that stay right on top the the process, ready to take it out and check it the minute it beeps, all this is much less needed.

do you have a link the the web site to upgrade our freeze driers to the new pro upgrades
I haven't seen anything on the website about upgrading yet. At this point I think you just have to call them.
Do you think it would have been okay if your sister went more batches without changing the oil? Could it go 100 batches?
I honestly don't know why not.
Maybe the oil breaks down over time and loses some important property? We certainly saw no issues with it; as far as I could tell it was still perfect. Maybe a vacuum-pump-oil-scientist will chime in and let us know!
Curious, if I end up getting a new pump does your link give you credit for that also? Or just for new freeze dryers?
😁 As far as I know it's for anything.
@@SchoolReports sorry I didn’t think of it when I ordered the hose. Two valves, new hose, still no good. 🙁
@@eileenniehaus5368 I wish I could get my hands on that machine!
