Description
A low‑temperature spray drying method that freezes feed and rapidly sublimates ice in a hot gas stream.
Technical
The feed is chilled to –30 °C, atomized, and introduced to a drying gas at 200‑250 °C. Within 1‑3 s the ice sublimates and residual water evaporates, yielding a powder with <5 % moisture while preserving heat‑sensitive nutrients and volatile aromas.
