    It may help to add a desicant to the cold trap. Takes up volume so less work to pull the vacuum. Provides surface area to condense on, and or absorbe moisture helping to sustain a vacuum.
    Im guessing these are possible:
    1) Dry heat treated uncented cat liter
    2) Dry heat treated crushed sheet rock
    3) Dry heat treated calcium chloride
    4) Dry heat treated silica gel, sodium silicate.

    For freeze drying (actual sublimation) to occur the vacuum pressure needs to be below 6 mbar absolute. With it being well below 1 mbar in manufactured freeze dryers.

    • @dilloncarhart7929
      @dilloncarhart7929 2 года назад

      So 5pa would do the trick? I know nothing about this stuff but im trying to figure it out. If im correct, 5pa would be less than 1mbar? I know this is an old comment but I need to know! lol

  • @kenkneram4819
    @kenkneram4819 8 месяцев назад

    Could you please clarify how to use the freeze dryer?
    It looks like the food chamber is outside it at just over room temp on the hot plate.
    Is that correct?
    I actually want to make my own freeze dryer because I don't like the harvest right model due to it's having to be defrosted so frequently.
    Also I want to do good size batches back to back.
    I already have the freezer and a water collection chamber.
    I'm planning on using an air tight box with shelf supports for the food chamber.
    (Think commercial bakers rack with an air tight chamber.)
    I'll be building that out of wood with a sealed polycarbonate shell on the outside.
    I'll be using aluminum sheet pans for the food trays.

  • @frosty992001
    @frosty992001 6 лет назад +1

    It was almost really good. It was entertaining and it gave me some ideas. The process you are using seems a tad flawed though. Perhaps try putting the pressure cooker in the freezer with the lid off, wait for the strawberry to freeze solid, put the lid on the pressure cooker, then turn on the vacuum pump, get it down to the right vacuum, and leave it for a few days and see what happens? I would be very curious to see the result.

  • @Patriot3
    @Patriot3 6 лет назад +1

    Don't you put the pressure cooker in the freezer? And a small heat source under it.

  • @johnwang9914
    @johnwang9914 8 лет назад +17

    Nice but that's not freeze drying as the product was not taken below it's eutectic in temperature hence you had chemical degradation as the water went from liquid to vapour instead of solid to vapour. What you have is a vacuum chamber dryer.

  • @noworldorderforme
    @noworldorderforme 9 лет назад

    I like the idea of a portmanteau show with loads of little ideas, hints, and builds all coming together. As always, I'm fascinated by Rob's chemistry bits and I think that part could be expanded by combining it more with the foraging section to show how chemical products (inks, paints, glues, perfumes, medicines, etc) used to be made in the past. I've got to agree with the comment below about getting a better solution for miking you all up and getting the sound right though, it really would make the whole thing much better. I've only got one small question to ask; apart from it being cool to do, why exactly did you want to build a freeze dryer in the first place?

    • @ThinkingandTinkering
      @ThinkingandTinkering  9 лет назад

      David Worth that's a good idea mate - i like it and will use it if that's ok - we want one to freeze dry graphene foams and sponges

  • @Oseois
    @Oseois 9 лет назад

    what would happen if you freeze dried a graphene solution? It it held it's structure, might be a great conductor. Stick it in some DES with some aluminum foam, which you could make with your vacuum set up, and you might have some pretty decent results from your rechargeable aluminum air battery.

  • @dalilgiorgi994
    @dalilgiorgi994 9 лет назад

    Fantastic! good job! i also buillt one, is very usefull tool. another interesting think you can do with freezer dryer is a thermic insulating organic sponge made with agar-agar! Agar-agar gelatin is biodegradable polysaccharide so i suggest adding silver nanoparticle for inhibit microbial degradation. ;) (y) I look forward to the next episode!

  • @MathewTitus
    @MathewTitus 9 лет назад

    Very entertaining! Good idea to pack all those little titbits in-between the main show! Makes it far easier to actually keep the audiences' attention. The audio is a bit soft in areas (remote mics, maybe?) but this is certainly quite an improvement from the lecture hall format in earlier shows (not that I mind - I teach) :)

  • @joesmith7427
    @joesmith7427 7 лет назад +1

    he is using a Laboratory vacuum pump, and it will draw a real deep vacuum, unlike a refrigeration vacuum pump. sublimation is when something goes from one phase directly to another and it skips over one of the phases which it normally would go through, like a solid to gas, it didn't go liquid then to a gas! eutectic is something different, u need to learn what is! its the highest and lowest boiling points of liquid!

    Good content guys, really good stuff, but you need to invest in some audio equipment to put a mike on each of you and normalize the sound. In some scenes the speaker is barely intelligible due to background noise and the distance from the microphone, others had me scrambling for the volume control as they were far too loud.

  • @trailkeeper

    You probably know this, perhaps increase the surface area in the freezer/condenser, perhaps by removable metal plates. This would give the moister an increased chance to condense on one of the various surfaces. update, feb 2021, thanks for the piece on the oak apple , disease. I see some here in Pa, Usa about a year ago and managed to look it up what it was. Something about induced dna mutation by the fly may be involved.

  • @billybareblu
    @billybareblu 7 лет назад +1

    I have to say I'm disappointed in the final product, and you need only do a photo or video search for "home freeze dried strawberry" to see that something is amiss in your setup. The extra bit about making ink was great, and the banter is somewhat entertaining, but the point of watching is really to see how to make a WORKING freeze drier setup. So when your project doesn't work out, either figure out and correct what's wrong or chose a title more fitting, like "The day we tried but FAILED at making a freeze dryer". CHEERS!

      @MaxQ10001 5 месяцев назад

      And it should be frozen. Now the strawberry is at room temperature, then they cool and heat the air and water before warming it again. It's like serving raw potatoes and cooking the skin before throwing it in the garbage 😂
