I appreciate how scientific you are with this freeze drying. I am getting my FD this week and have been watching many diff videos. I have been on earned how nonchalant some people are about not knowing if their food is truly dry. I don’t want to invest all this money and time and then have it not be edible in a few years. Thank you for all your hard work and explanations.
Nonchalant. And sometimes just downright silly! Thanks for watching, commenting, and for the kind words! I hope you find some of it useful. Isn't it amazing how much water is in "dry" food? This experiment even surprised me. "Remember kids, the only difference between Science and screwing around is writing it down." The only really important thing is the _Dry Check._ As far as I'm concerned, anyone who is bagging any food for storage without doing a _Dry Check,_ using a sensitize scale, is wasting their time, food, and money. Without the _Dry Check_ you're just guessing as to whether or not the food is dry. This is my personal guideline about dry food: 🤣(Only a little tongue-in-cheek) #1 Never trust the freeze dryer or a spot check moisture meter to tell you if the food is dry! Do a Dry Check using a scale to make sure it's dry before bagging and storing. #2 Don't overload the freeze dryer. I try to keep the medium machine to a maximum of about 8 pounds of Water Weight per batch. (I have had 11+ lbs of water. It took a long time and I won't do that again) #3 Don't make the food on the trays too thick (height, not viscosity) If you do, you may have to run the batch twice. #4 When in doubt about dryness, add extra final dry time. #5 Never trust the freeze dryer or a spot check moisture meter to tell you if the food is dry! Do a Dry Check using a scale to make SURE it's dry. #6 NEVER trust the freeze dryer or a spot check moisture meter to tell you if the food is dry! IT CAN'T KNOW! Do a Dry Check using a scale to make SURE it's ALL dry before bagging and storing. I've heard from too many people that thought their food was dry, only to check again a short time later (or a year or 2) and find out it wasn't, and now it has gone bad. My biggest issue with the Harvest Right manuals is where it just says ". . .Check the material thoroughly to make sure it is completely dry . . ." with no hint as to how to accomplish this in a way to _ensure_ it's 100% dry every time. I have a bad feeling that a lot of people are going to find out someday that some of their food was not dry enough. Many foods can hide moisture that's not noticed at the time of bagging. #1 rule of freeze drying - Never trust the freeze dryer or a spot check moisture meter to tell you if the food is dry! _It can't know!_ I'm paranoid about having water in my freeze dried bags of food. 🤣 Remember, I'm just another idiot on the internet. I could be wrong. The #1 joke at our house is "But, I saw it on the internet!" Consider looking at what commercial companies are doing. That's where I look to for guidance. If they can do it, we probably can too. (with method adjustments)
I find it incredibly interesting as to how much water WAS in those two food items in their shelf packaging. This video is a great lesson in understanding how or why FD'ing makes a whole lotta sense.
It was a surprise to me just how much water there was. I was really happy that the water demo at the end shows the issue so well. (At least in my opinion) Maybe I should have given this video one of those stupid over-the-top TH-cam titles; I FREEZE DRIED SOME "DRY" STUFF - YOU WON'T BELIEVE WHAT HAPPENED!!! with the equally bad open-mouth (pretend) shocked face thumbnail.
@SchoolReports I have, for quite some time now, wondered, "Can I vacuum seal DRY goods and be confident that it won't spoil?" The reason I have asked this question is that I know there is still water in all dry goods. they are dry enough to be shelf stable and safe for short term, 1 to 2 years, storage. but I want long term, 25 plus years, storage. the only way to guarantee that is to remove more water. I like the weight and temp measurements for determining "doneness." I will adopt that practice. the demonstration at the end drives home the fact that "dry, really isn't dry." you could add the cheesy thumbnail pic and the over the top name, and you would probably get more views. But then it would degrade the value of the video. in my humble opinion. but I am kinda nerdy at times, so take it for what it's worth.
I just got my new Harvest Right fully hooked up and am getting ready to do the batch of bread to burn off the "new car smell" as the book calls it. I've got a list of foods to freeze dry. I appreciate all of the work you've been doing to make these videos. I've learned a great deal from you.
Congratulations! Good for you to have a list of things you plan to do. Until I started making the "First 50 Batch" series of videos, we had never even given much thought to having any plan or goal for our freeze drying. That was one big reason I started making the series, to tell other people to start with a plan or goal. Any plan or goal!
@@SchoolReports I need to rewatch it, I was busy when I watched but it looked a bit complicated for me, all those little pieces. I bet they taste amazing though. Maybe some day... Taking another break from freeze drying cause of life and work.
I know I was surprised! I knew there would be water in the "dry rice," but even I was surprised by the amount. I was trying to illustrate that there is no way to tell if freeze dried food is finished drying just by feeling.
How much water do you think is in NON minute rice? I ask because people say standard rice in mylar can last decades (which was my thought). But is there water in those? Guess I may need to try... Thanks School!
@@annwithaplan9766 Might be good as an addition; I would still remove the water first. 🙂I don't see how leaving the water in the bag with the food and just adding a desiccant could be a better option. It could be an interesting side-by-side experiment!
Hmm I've seen other people do the dry hash browns- thought that was a neat way of extending the shelf life. Never thought to do the minuet rice- cool. What do you think about FD'ing cheerios, have you tried to FD these? Might be a fun experiment.
Thanks for watching and for commenting! The freeze drying process really is a lot simpler and quicker than the prepping and cooking most meals! I do show a lot of steps that are not "required" for the freeze drying process because people have asked to see them. But on the other hand I want to be realistic about the process. Some people doing freeze drying pretend that the machines can "know" when the drying is complete - they can not. The total needed hands-on time is actually very short and easy if you're not trying to document it on video. Like most new things, it seems a bit complicated the first time, but it's not. Like learning to ride a bike.
I just use the preset setting and add more time, if I check the food and it seems wet. You can taste a tiny bit and tell if it's cold or chewy. Check all parts of the tray. Food that's done is like styrofoam. He is very scientific! He's very smart. I guess I just trust the setting and check the food, by taste. I'm a Grandma, not a scientist....LOL
@@coloradogirl9913 Thanks so much for watching and for commenting! I'm currently working on a video about the _Dry Check_ process. Hopefully I will be able to show the simplicity of it and the need for it.

Great questions! I'm sure wear and tear change the seal over time. Some peoples machines do seem to seal easier/better than others. Mine would probably seal most of the time even if I didn't do anything. Mine, my sister's, and many others don't seal perfectly every time, so I like to make sure; it only takes a second.

Uncooked rice is complicated. Dry, uncooked rice is going to be over 10% moisture by weight, depending on the temperature, but it kind of needs some of that moisture under "normal" storage conditions. One of the problems with water in food, when in a sealed container, is that the humidity levels change (a lot) with temperature changes. This can change safe Water Activity (aw) levels from a safe range to an unsafe range. This article talks a lot about the subject of moisture levels in rice: Rice Drying, Storage and Processing: Effects of Post-Harvest Operations on Grain Quality - www.sciencedirect.com/science/article/pii/S1672630821000998
Great video, do you know the rehydrated difference between cooked rice and dries rice? Also the difference between frozen hashbrowns and dried hashbrowns?
I'm not sure I understand the question. Do you mean home cooked rice and then freeze dried vs freeze drying minute rice vs uncooked raw rice? In all cases the more it had been cooked before freeze drying the faster it will rehydrate. The frozen hashbrowns will rehydrate quicker than the ones that started out as dried.
Why would you not use your own farm raised food? I get preserving, This is a terrible idea. Your also storing the preserves and chemicals! Antibiotics and more. Terrible idea!
