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.

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

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

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.

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

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

[KevinWorrell]

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