The material is frozen first; ice then sublimates directly to vapour under vacuum — low temperature throughout, so structure, flavour and nutrition survive almost intact.
Blast-frozen deep below zero; fine ice crystals fix the cell structure before it can degrade.
Under vacuum, ice turns straight to vapour — no heat, no structural collapse.
Bound moisture is removed as temperature rises, leaving a light porous body that rehydrates in seconds.

We prove your material on a pilot unit, then scale to industrial models.
