    This machine is also used to salvage wet books, since it can make the water evaporate without heating the paper too much. This process is the best solution to try and save libraries and archives’ collections if they get wet, as in floods and hurricanes. It's funny to think that if a library gets wet the best option is to put the wet books in freezer cells and store them until there’s one of these machines available. They are not that widespread yet and the process is very slow, but it does work. I have not finished the video yet, but I really hope Alec will try wet paper in there just to see what happens since I've never seen the process take place!

      @robdidopp7769 Місяць тому +209

      To add on that: the opening that the pump uses is much, much smaller than the surface of the drum and at such a low pressure you're not really creating a significant flow of gas to the pump, you're again just waiting for the molecules to more or less randomly find their way to the pump. In short: if the drum wasn't cooled during the drying, the pressure would significantly increase and the whole thing wouldn't work anymore.

      @@tz8785 Once the air is out, almost all the pressure comes from the water vapor (assuming you didn't e.g. try desiccating something alcoholic). What you want is to remove that as quickly as possible to keep the pressure down and not impede further evaporation. The best way to do this is to just cool down the drum to the point where the vapor freezes on it. Yes, the pump would also keep the pressure relatively low compared to ambient conditions, but the pressure would be far higher than what can be achieved by just keeping the drum ice cold.

For liquid products you could run them in ice cube trays you have to run them for an extra 24 hours probably, i personally despise the silicone trays from harvestright. On the note of peppers being hotter, capsaicin is a pain in the ass molecule due to being an oil so it is not disturbed at all and it spreads out in your mouth as soon as your saliva interacts with the dried pepper. -edit- silly me for forgetting this dont and i mean don't filter and reuse the oil, it will ruin your pump dont be like me and follow directions on the package, just buy new oil "Black Gold" is a good brand.

    Hello there Alec, I really enjoyed watching your video on lyophylisation, big props!
    Because I´m a pharmacist - or as we Europeans like to call it, an Apothecary - I can add a little something to this:
    If I recall correctly you made instant coffee with this. In the industry this is achieved with spray drying. You put solutions, emulsions or suspension and atomize it via a nozzle. Then you add some fairly warm or even hot air stream to the mix and it gives a nice powder or granulate which can be reconstituted with water easily. As far as I know that is widely used in the food industry to, for example, produce instant coffee or powdered milk. But it has some neat pharmaceutical applications as well!
    Lyophilisation is more heavily used in pharmaceuticals than in food, because it is much more expensive in equipment and time - as you have thouroughly demonstrated. And in medicine price is way less important than in food products.
    Now to my little hypothesis: instant coffee tastes awful, because of the heated air applied. This will denaturate proteins and oxydise some aroma molecules in the coffee, thus leading to the altered, inferior taste.
    Love your content in general, hope this finds you well. Have great weekend!

    12:49 Hi! I work with Ultra High Vacuum equipment! The reason the water deposits on the sides is due to the how the particles in the chamber interact. The air molecules are basically bouncing around the chamber randomly and the pump is just scooping them out when they reach the vacuum pump. Imagine a crowd of people PACKED in the lobby of a hotel and milling about, but they only change direction when they hit the walls or each other. The only way out is through the automatic revolving door that scoops people out as they bounce into it. More people will bounce into the door when there are more people in the lobby to bounce off of, but the fewer people inside, fewer objects to bounce off of and the lower the odds that they'll bounce into the door. Now, you're still introducing more people to the lobby from the elevator, but it's still not packed enough for them to push into the door like they had earlier. Now, because the walls of the lobby are a bigger target than the door opening, and the walls are now cold, the particles will instead condense on the cold surface and freeze, effectively removing them from the chamber. Hope that helps!

      Wouldn't this be solved if you chilled the incoming air first so you could keep the interior walls no colder than the food inside? After all, if the food is net losing moisture then the rate at which ice on the walls sublimates should exceed the rate at which it condenses just like it does for the food if they aren't colder no?

Since the trays have heaters the water molecule in the food have more energy to escape and fly into the chamber while the ice on the walls is colder so its less likely to escape and fly into the charmer this small difference in average energy levels is what drives the whole process. fun fact if you take this process to the extreme by cooling the wall to near absolute zero you can "pump" all the gas out of the chamber not just water but the air as well by freezing it.

They couldn't find any prepackaged meals they really liked so they bought one of these and now make their own freeze dried meals that they like better and can customize to their own taste. Those pre pachaged meals are not cheap and they were going through enough of them to make the initial cost make sense. They also don't mind the work so that's not a huge issue. As a side benefit for them (and me occasionally) they've started making fruit and vegetable powders. The cherry tomato powder (which is just freeze dried cherry tomoatoes you wizz up in a food processor) is particularly good to use on and in things.

    As for the difficulty with reconstituting the milk: if you mix the desired amount of powdered milk with a *very small* amount of cold water, you should be able to create a slurry which will allow the fat to emulsify. Then you can add the rest of the water. I do this when making cocoa with pure cocoa powder (I don't use sugar). It faces the same basic challenge due to the high amount of fat in cocoa powder.

      Yes, this is correct.
      Milk contains spherules of fat that stay suspended in water, but removing the water destroys the vesicles, and allows the oil to coalesce.
      To resuspend the fats, you need to add water and lots of stirring. If you do it with full water, it spills and froths and churns. Just use a tiny amount until it's all dissolved, then fill to 1/3 and stir hard (scrape bottom corners), then fill to 1/1 and it should come out nice.

    And then it's basically directly add warm water, warm not directly boiling and let it sit for a bit. Preferably sealed with the moisture against it directly.

      This way they can transport loads of food up there and recycle water and rehydrate the food.

    I use a freeze dryer at my work to prepare samples for analysis for total mercury content and other geochemical processes. Our system is set to -50 C and 0.165 mbar, there is no programmed end time. We will leave our samples for at least three days , then if it passes a visual inspection, we would then physically check each sample for a "cold" feeling. If our sample feels cold to the touch, that implies a piece of ice is still remaining in the centre and that we need to continue the process.
    We have an 18L collection chamber and often if the ice on the collector is too thick we need to pause the run defrost the collector, dry the inside of the unit, and then continue the run. I can only imagine that this at home unit is going to be closer to our older 2.5L unit where we had to defrost the system every two days so that the samples would maybe dry in a week.

It also allows for easier homogenisation and breakage of cell walls, which furthers the ammount of DNA extracted.

    Fun fact: Freeze dried onions is what goes onto the McDonald's Cheeseburgers, Hamburgers and Big Mac. (Most other burgers like the quarter pounder and similar use fresh, chopped onions) We had these big bags of freeze dried onions and would just dump them into a big bowl of water to soak. After that you just scoop them out with a big sieve.
    So basically you freeze dried some freeze dried onions when you freeze dried your cheeseburger.

    To anyone who needs to hear it: Instant coffee is pretty much as good as the coffee it was made from. The original nescafe was a war ration product that used leftover beans that no one else wanted, and most of the lowest price instants today still use crappy coffee. But, there are many brands available in mainstream grocery stores that reconstitute to produce a cup of coffee which is pretty much coffee-house, fresh pressed espresso taste and mothfeel, and it breaks down to like $0.10 a cup. Medallio Doro, Cafe Bustelo, and surprisingly even the Starbucks Premium instant are all very, very good. And if you like espresso drinks, like lates, instant espresso is a great way to make those at home by microwaving a mug of milk, adding your instant coffee, and then mixing/frothing with a $10 handheld milk frother. No scullded milk mess, no espresso machine.

    "For physics reasons im not quite sure of" Physicist here! There are two reasons to keep the walls of the freeze dryer frozen. First is a technical limitations of many vacuum pumps, generally speaking vacuum pumps don't respond well to water vapor so we want to keep it out. The second reason is that when you are heating up the solid water it is evaporating at quite a high rate. Even at atmospheric pressure going from solid to liquid is a roughly 700x volume increase. Additionally, at the low pressures required for freeze drying the efficency of vacuum pumps drops dramatically (applied science does an excellent explanation of this in his video on a glass diffusion pump) so they can't pump nearly enough water vapor from the chamber to keep the pressure down. Thanks to the refrigeration cycle it is very easy to make a really cold surface. When the water molecules run into the cold walls they loose energy and end up sticking together, forming ice in the process.

    I have some experience with larger and bench top pharmaceutical lyophilizers. The end of drying cycle is triggered by increase in the product temperature. This happens when there is no water to evaporate in the product being dried and the heat being supplied to product is no longer being used for evaporating the water, since is all gone, and the products starts heating. This spike in the tray temperature is picked by the sensors on the tray ( as you showed on one of the trays) and used to take the cycle to the next stage. In commercial units; this sensor may sit in one of the product container or on tray for accurate measurement.
    So in the unit you showed the decision is made on the basis on the sensor on one of the trays ( and the state of drying of the food on that tray). It also means that having different food type in one lot may not be a good idea, as you have experienced.

If you're on solar you're also going to have way more available power at the exact same time. Put the two together and you can freeze-dry all that extra food. Most of the people I've seen doing it just powder all their extra veggies and herbs and use them in soups and stews and baking; reconstituted eggs work just like regular eggs for cooking and baking.

    - drying flooded things (like books)
    - preparing food for camping trips, trucking or any other job that requires being away from home for long periods
    - making interesting dishes and ingredients : drying out spices and herbs, tomatoes, making powdered milk and eggs...
    - science stuff (mostly turning solutions into powders)
    - making dog snacks from bad meat (like pig ears or other animals you butcher yourself)
    - selling the stuff you make with it, so you can benefit the community around you.
    I think that you would need the niche applications and/or have several applications in mind, because a single one isn't enough. Especially if you have a neighbor who owns one.

    Freeze dried yogurt is one of my children's favorite things from our freeze drier. So are just about any fruits, though some definitely work better than others. One of our favorite things is freeze dried berries mixed into ice cream or used in cakes or cereal. Even freeze dries marshmallows turn out really well. One of our favorite uses was freeze drying snacks to take on hikes and things to reduce weight. And everybody loved them.
    As for the work required to use it--you aren't wrong. It takes a good deal of time and effort. However, since the kids inhale whatever we make, we package things in regular ziplock bags and set it out where they can get to it! Disappears within a couple of days. We do have a vacuum sealer that we've packaged some soup veggies and stuff in, which was neat, but I concluded it was too much work for also raising kids and living a somewhat normal life.
    We have wanted to try liquids, so your experiments with those were helpful to us. For our part, I would say that overall, I have found that a freeze drier (this same one, actually) was a good purchase because of the snacks and treats that my kids will eat that are healthy, and makes food fun for them. However, we probably haven't used it enough yet to validate the cost, but over time I think we will have. In other words, amortized over the life of the device, I think we will absolutely get our money's worth using it mostly to make snacks and treats for the family with an occasional meal (like soup packet) or something thrown in. Not using it for apocalypse prep, it still makes sense in a family situation. I probably wouldn't buy one if it was just me or even just my wife and I.

      This was my thought as well. Gastro-engineers would love this thing for making flavored powders. I bet it's fantastic for things like alcoholic drink flavorings. Or frostings like you mentioned.
      I think the critical thing is that you really need to understand the chemistry of what you're doing to make this work. For example, freeze dried potato powder could probably be reconstituted and pressed into fry shapes before deep frying into french fries.
      Meats and breading should probably be separated and reconstituted independently, then combined to make the final "nugget"-like product.
      All of which is fascinating if you're planning to work with SpaceX on the loadout for their Mars supply ships in a year or two.
      As a "fun" cooking method though? It will probably go about as well as your average person trying to use a dryer to make banana chips. Won't work nearly as well as they expect and they'll hate it almost immediately. Sort of like TC! .😂

    The major use case you’re missing: hikers. It doesn’t matter that the food tastes bad while dehydrated- the idea is to make shelf-stable food you can rehydrate on the trail for FAR cheaper than the commercially available hiking meals. It doesn’t make sense for casual campers, but for people who do months-long thru-hikes or bundle up their whole family for long camping trips, it would pay for itself over time.

Most notablyin the door being a dome held in place by a bar with center compression point that solves the issue he was having with the hinges & latch) and we used it to make stuff for taking on extended hiking and camping trips. Mind you there plenty of things it's not a good option for but for the things it works well for you can reduce the volume and weight considerably making it well worth the investment for the extra supplies you can carry.

    So, the Scoville scale was originally based on _dilution_ until it was no longer detectable. Gas chromatography has since taken over, but the scale still reflects the original “100% is 16 million” scaling as a unit. So, by removing water from the jalapeño, you’re increasing the percentage of the substance that is capsaicin, and decreasing the percentage that is not. Thus, the result really should be higher on the Scoville scale.

      Plus, capsaicin bonds better to oils than water, so removing the water from the jalapeños give more contact area to the oils on your skin or whatever food you’re putting them on. Super concentrated little jalapeño burst, given even more power to strongly bind to oils in foods! It sounds pretty good tbh.

    Funny you mention the scenario of the spouse wanting to get a fancy machine and trying to convince their partner that it's a good idea. This happened to me in early-ish married life when hubbie thought getting a food dehydrater would be a great idea. By that time I was working outside the home and managing 2 young kids, so didn't have the energy to learn something new, and told him so. He bought it anyway, and it sat unused in the basement in its original packaging for at least 25 years. My older daughter rescued it as I was selling the house. She went on a dehydration binge this summer to make her own backpacking meal kits. She now has a couple dozen Mason jars of dried food which will last a while. It seems like a much more energy- and time-efficient way to preserve food, even considering the taste and quality differences.

      Also there's an easy trick to calculating rehydration ratio (at least with traditional dehydrating but don't see why it wouldn't work for FD)-just weigh the food going in and then the dried product, and add about the difference to rehydrate (at least as a starting point to then trial and error from, since dehydration and rehydration aren't precisely symmetric processes)

    We only use it a few times a year.
    About the freeze dried cheeseburger, throw it into a blender and sprinkle it over your self made potato chips. I'm pretty sure this is close to how Lays do there special flavor varieties.
    Surprisingly soup also works well. Actually, most things that you can already buy in a powdered form works great in a freeze dryer. It is just that you now know exactly what is in the powder.
    For the same reason we created our own baby food. Not only did we save a lot of money doing this (helps paying off the freeze dryer ;-), we like to know what we feed our children.
    It is also a fun activity to do with the children. They love taking out the trays, take the herbs and turn them into powder. But only for a hour or so and than they want to do something complete different.

    12:40 i've had a thermodynamics class and am happy to try to explain!
    The reason water vapour is "attracted" to "coldness" is because it takes up less volume in the solid state!
    The water vapour, being a gas, spreads evenly throughout the chamber. The cold walls desublimate it because phases (to explain phases you do need a bit of thermodynamics but i think people intuitively understand phases), but that means there is
    1) less space taken up by the water.
    and
    2) less water vapour in the air.
    Since water vapour spreads evenly by being a gas more vapour fills in the lack of vapour and the cycle continues.
    It is diffusion creating the illusion of force, since there is a source a sink and a way to spread, a gradient emerges. Just like diffusion of heat creates the illusion of cold.
