Freeze drying, also known as lyophilisation or cryodesiccation, is a low temperature dehydration process that involves freezing the product, lowering pressure, then removing the ice by sublimation. This is in contrast to dehydration by most conventional methods that evaporate water using heat.

Many thanks for the nice presentation. I have a question on the final step secondary drying. If the temperature is increased to 50oc heat-sensitive products such as microbes will lose their viability, what do you think about?
Sir i have a Question that why slow rate of cooling is recomended during the process?
Thanks sir nice teaching
Sir ion exchange chromatography explain cheyyandii
Sir , ur teaching is awesome
Plzz post more videos on microbiology of bsc degree
Thank you sir ✍️
My pleasure
Thank you
My pleasure
Sir please make a video series on Developmental biology and add it on your playlist.
Sure
Need pbf this lecture
You didn't explained well. Watch pogo instead of teaching kiddo!!👎👎👎
