What is Freeze Drying?

A short video to simply explain the freeze drying process and how a freeze drying microscope can be used to optimise the drying cycle and save millions of dollars.

There's an error here. Fast freezing leads to small crystals, while slow freezing makes large crystals. Usually.

[@alexbrd9686]

You are right!

[@lyleon2216]

Exactly

[@PiranhaFisher]

I understand the microphone tastes good but you need to keep some distance to sound clear in the video

[@nilbeseoglu]

LOL!

[@CornKaine]

@@seabassmoor you dont sound much better

[@East_Coast_Toasty_Boy]

Damn

[@rockinggirl0610]

CornCultistMike lol

[@skyhigh5926]

AHAHAHAHA

[@RunningFreeForeverFree]

What a great video. Your a great artist too!

[@williamkusnanto2948]

I think, you must revise the video about the slow freezing and fast freezing. slow freezing make it bigger crystal ice so the water is easy to remove

[@josephzerbe2945]

Very informative great job!

[@RinaMaster77]

your voice makes me feel like I need to catch my breath.

[@East_Coast_Toasty_Boy]

Lmao

[@everyone210]

Inspiring in easy words gives many knowldge thanks sir

[@Woodscraps-lr5vz]

Good job on this video. The explanation was well done.

[@WH6FQE]

And the cost of freeze drying for experiments is why I invested in a home freeze dryer for a fraction of the costs that doesn’t use liquid nitrogen.

[@mh-on7fp]

Great video, love the drawing!

Hi linkamscientific,
I have question about Freeze Drying,
By the way,
Why the original SHAPE of product is kept after the process finished ?
I hope I would receive your answer soon.
Thanks linkamscientific, so much.

[@TheAminadz]

thanks very easy to inderstand and memorize

[@eydum3948]

I really liked the explanation.
I originally watched a video called 'How to Build a Freeze Dryer' and got alot of the information on this topic then came here and this cleared up nuances I noticed and misunderstandings
The first video primarily got me to understand and familiar with the vocabulary used in this video as well as an overview
This video pretty much covered everything just not vocabulary (that would only make a difference for the average person, someone who's already familiar with this topic will not have a problem with that)
Any way good video
I liked it;)
And byee

[@eydum3948]

Actually now that I think about the warming it up a little bit while it is under low pressure and Frozen, the way you explained it with the visuals kind of made it seem like u were slowly burning it.
Though thankfully I understood it's just bringing it to and above its current freezing point very slowly

[@eydum3948]

Of course I still like video tho, also I know I'm 9 years late to the party:P

[@m.r.b.806]

This is a very poor description that does not even address each of the four steps it originally laid out.

[@cuentas217]

I love this because he's a great drawer but like everyone, letters escape

[@MarcassCarcass]

So freeze drying does destroy some of the nutrient content in food because of the size of the crystals? What factors give one smaller ice crystals, causing less damage?

[@daudman675]

In slow freezing the water extracted out from the cells of the product causing this damage , but this not happen in fast freezing

[@nardsbalanggai5571]

Please sent price qoutation of freeze drying we buy 2 units thanks

[@StaatsBrad]

Has anyone purchased the newer generation Harvest Right Freeze Dryer? My friend has an old one the I'm just not sure I want to drop that amount of money. Whew!!!!

[@Docstantinople]

Now I’m just sitting here wondering if we can freeze dry a human being

[@CornKaine]

I would pay to see that

[@daudman675]

Must slice 1st

[@JulieTiger]

We can and we do!... google "green burials" ... they're very expensive and sketch in legal eyes, but it's a damn cool process.

[@dakotablanks2893]

no worries mte well have this food forever -marvin

[@finewine7253]

Que?

[@KevinWorrell]

Faster freezing = smaller ice crystals Slower freezing = larger crystals and greater disruption of material

[@stevet8121]

I was watching him draw and didn't hear a word he said.

[@gernblenstein1541]

Start at 0:21, set playback speed to 2X. Otherwise, I get it.

[@MarcassCarcass]

If you're just bringing the content down to the triple point, all the water is not really frozen, so how can you truly say that you're freeze drying something?

I can't hear you speak loudly

[@RedfishCarolina]

So, it's induced, extreme freezer burn.

[@chriss.3479]

Terrible explanation of something so simple
