What is Freeze Drying? 

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

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

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

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

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.

What a great video. Your a great artist too!

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

Inspiring in easy words gives many knowldge thanks sir

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

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

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.

Very informative great job!

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

Great video, love the drawing!

thanks very easy to inderstand and memorize

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

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

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

I can't hear you speak loudly

So, it's induced, extreme freezer burn.

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?

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?

Terrible explanation of something so simple
