FOR MOISTURE DETECTION: After dry cycle, take the trays out and let them sit for 2 or 3 minutes. Then feel the bottom of the pan. If you feel a cold spot, your food is not completely dry. This is from my go to guy for all of my freeze drying questions. He’s been doing this for about 8 years. Thank you for this wonderful channel.

Thanks for watching and for commenting! That (if the food temperature has made it to the set temperature) is always a good _first check_ and it's why we put thermometers in the food; we don't have to stop the machine to feel the tray, we already know the temperature without taking it out. More importantly, we know the temperature of the inside of the food. While the fact that the tray is cold _may_ tell you that the food _may not_ be dry, I would _never_ assume that having a warm tray tells me that it _is_ dry. Cold does not equal wet and warm does not equal dry. It's the same with thermal imaging cameras, they can't tell you if the food is dry it can only tell you it's warm or cold. I could fool them all day long. I guarantee that commercial companies aren't feeling the bottom of their trays to decide if the food is dry. I would never recommend that people go by feel or guessing when it comes to making sure the food is dry. I'm not trying to convince anyone of anything, I'm just trying to show what I do and why, and show resources when I can. 🤣 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)

You don't want to put warm metal pans with food in a Freeze Dryer because the difference in temperature will cause the metal pan to warp. Therefore, ruining the metal pan. It's a great idea that you always freeze your food along with the pan. Also, if the water that's left over, it's also a good idea that you might want to reuse the water for cooking or personal use if it's not contaminated.

Thanks for all your step-by-step videos. I've learned so much from watching already, and I haven't even got my freeze dryer - yet. Got a call from FedEx and will be picking it up tomorrow morning, directly from the terminal. I will faithfully be checking weights to assure the end product is DRY. Thanks again. God Bless.

Watch out, freeze drying is addictive! 🤣 Have fun.

Really great video as always. Have enjoyed watching all of the great things you freeze dry. You are an inspiration :)

Just a little trick, If you do milk or some other liquid by the pound and put it into pint bags to store. You can rehydrate by adding water up to the "ziplock" thing. You shouldn't need to calculate the water to add back because a pint is a pound.

👍 True; that's close enough for a lot of things. For milk the " pint is a pound" is only about 3 or 4% off.

I must confess watching your first few videos and not having my machine I was overwhelmed! HOWEVER, I see what you're doing now, understand the process and the method behind what you're doing, and I am so appreciative of these videos. I too want to know exactly how much water needs to be added for reconstitution. Hubby isn't really stoked about this and so adding the exact amount of water to the bag will help him relax with this new meal prep. technique. Can you do a video on the math for like a single serving of an item like stew or whatever. My husband and I eat separately and that's how I cook and freeze tv dinners for us, have done that for 20 years. Also, can you tell me why you do grams instead of oz, conversions isn't one of my strong suits and my husband wouldn't know a gram from a truck. lol Lastly, I am a new subscriber so thanks and keep helping us newbies, Lord knows it is a time and money saver to have someone who's already gone through all the processes to make sure a good result is achieved. We are on a more then fixed income and food prices are killing us, so being able to freeze day for short term and long term is a real blessing.

Thanks for watching and for commenting! We use the 7" x 7" pans for prefreezing a lot of foods already in serving size portions. (We have been freezing in this pans for many, many years before we started freeze drying. Like you we would make and freeze our own "TV dinners" in these pans going back about 30 years) Prefreezing Food in Pans - kzread.info/dash/bejne/ap-ezdGxYtzTndo.htmlsi=FCGaajcPnls488zC&t=123 One of the great things about weighing out the portions before freezing and freeze drying is that when rehydrating all you have to do is add enough water to get it back to the same weight. For example - An 8 ounce portion of stew (before freeze drying weight) now might weigh 3 ounces. Just add the 5 ounce back and done! This is a big part of why I do the _batch worksheet_ I show in a lot of the videos. 😁I don't "know" grams either, but my scale does and my measuring cups have milliliter markings on them. I go back and forth between grams and ounces all the time, even during a batch. I often measure my portions out in cups or ounces, but I do the _Dry Check_ weights in grams. The main reason I like to do a lot of the weighing in grams is because grams are such a small unit that it gives me more confidence that my food is all the way dry. One ounce is more than 28 grams, so even if I use a scale that shows 1/10 ounces, that could be 2.8 grams of water I might leave in the food.

Great video as always thankyou for sharing :) And look at that T-Shirt today with the flag of a Beautiful Country of Australia :D

B. E. A. Utiful video as always! Again thanks for sharing 😊👍. P.S. I have a resolution to our ongoing idea of adding a "low vacuum" to help ensure better door sealing & prevent cycle issues. I contacted HR and asked if during the initial startup freeze if us as users could use the self test area and use both freeze & vacuum just like you would the normal op test in owners manual. Or if a software change in the automation portion to vacuum just slightly during initial freezing could be added. HR took notes and said they'd look into it (but no promises made). I tried this idea on my avocado run and it worked beautifully, no more door condensation or longer freeze times due to small air leak 🙂. Only thing to be aware of is don't short cycle the components (I can't imagine that's good, but that's just my opinion). P.S.S I tried my foodsaver and the motor got way too hot for my liking (I'm assuming due to the lager volume, it's simply to much for the small vacuum pump equipped in them.?) As always you keep posting; I'll keep watching 🙏.

Great info! The way I've done this in the past was to unplug the vacuum pump from the freeze dryer (just the electrical cord) and plug it into the wall socket and use the power switch on the vacuum pump and run it for about a minute to lower the pressure. Then I plug it back into the freeze dryer socket. I haven't been doing that much since I built the new cart because the plugs are in a tight space between the machine and the wall. (and I've been too lazy to roll it 3 inches! 🤣) I was worried about the Foodsaver overheating and now I don't have to try it, thanks. I think the Foodsaver is probably designed to handle a quart of air at a time, not a cubic foot of air!

@@SchoolReports I feel you on the lazy 😂, my machines on wheels and I don't want to roll it out either to move plugs. Although I did think about using a mini electrical transfer switch 🤔 but that's North of 70$.?! No worries on the foodsaver (I have a lesser model) so IDK if others might work better? I designed a quick reducer like check valves with a layer pause and imbedded a thin flexible plastic bit of cutting board as the stopper. Worked well, but again the foodsaver just dragged on (interestingly my pump seamed to be more on a timer rather than if it achieves an actual vacuum) thus I had to run it several times and just got to hot...

Thanks for watching. We have made applesauce, apple slices, apple pie filling, and apple crisp, but not apple butter. (When I searched our channel I was surprised to find 16 apple related videos!) The silver stuff is metalized film bubble stuff that is used for shipping cold stuff. (I think it may have been this kind, ipcpack.com/products/box-liners/ but there are lots of brands. I just used what I had.) We got our bubble stuff when it arrived wrapped around some frozen food, (a cake, I think) with frozen cold packs, from Harry & David. I saved it knowing that a use for it would show up. And Voilà! I put this on to better insulate the seal area and the little space between the seal and the rest of the machine (3-4mm gap) where the freeze chamber is exposed, because the seal would freeze and end up with ice and frost on it. Then, when the freeze dryer was defrosted, the ice would melt and water would run down the front of the freeze dryer. I measured the space between the door and the front of the freeze dryer and cut strips of the insulation material that wide. Next, I cut enough to wrap around the seal 3 or 4 time, taped them together end to end, and finally, wrapped it around the seal and taped the end. This may not be an issue on newer machines, I don't know. Adding Front Seal Insulation To A Harvest Right Freeze Dryer kzread.info/dash/bejne/fnVl1aqPhdSxpNY.html

Do you know if you can use Xantham Gum instead of Clear Jel as a thickening agent - so you wouldn't be adding all the extra carbohydrates ?? Thank you

@SchoolReports

Жыл бұрын

The short answer is - probably yes! I recently bought some Xantham Gum, but I haven't tried it out yet. If I understand what I've read about it, it should be a good choice for foods that are going to frozen and thawed. (Like freeze dried food) The labels say that the carbohydrates are the same, per weight of thickener, for both products. I assume that less of the Xantham Gum is used to achieve the same amount of thickening, therefore less carbs?

Ok do the mixed foods not take up the taste/smell of the other foods? I will assume since everything was frozen it won't but I just had to ask! :)

Thanks for the question. Most of the cooking we do has been in very large batches for many years, long (20+ years) before we ever started freeze drying. Our freezer used to be set up kind of like a file cabinet with boxes of frozen slabs of food like chili, beef stew, mashed potatoes, scalloped potatoes, etc. We don't plan most of our batches of cooking to necessarily match up with our freeze drying batches, we just make big batches, put the food in the 7 x 7 pans for prefreezing, and freeze dry it when time allows. We have had 15+ batches worth of frozen blocks in the freeze awaiting their turn. If this doesn't really answer your question, just let me know and I'll try again. 😁
