A question about dehyderating.

[Sunny789]

Can someone please tell me the industrial and non industrial methods of dehydration, I mean, I want to know any new methods rather than the usual sun drying/oven heating or dehydrators, I mean, I need a different method, thank you.

What are you dehydrating? Instant coffee is sprayed into a vertical tube with hot air, some products are dehydrated in a vacuum so that there is no heat.
