Abstract

In order to provide for a method for producing a fog of stable ice nuclei having a defined and/or preferred size, the following steps are proposed: [a] introducing a humid carrier gas into said freeze dryer (A), thereby forming a water vapour region (C); [b] introducing a cryogenic fluid into said freeze dryer (A), thereby contacting said humid carrier gas and forming an ice fog region (D) surrounded by said water vapour region (G); [c] introducing a humid carrier gas into said freeze dryer (A), thereby forming a second water vapour region (F), with said water vapour region (G) and said ice fog region (D) mixing to form a mixed growth region (E); and [d] introducing a cryogenic fluid into said freeze dryer (A), thereby contacting said second water vapour region (F) to produce a second ice fog region (H) within said second water vapour region (I) and said mixed growth region (J).
