    摘要: In a process for producing a pulverulent product from a liquid substance or mixture of substances, the liquid substance or mixture of substances to be pulverized is first provided in a pressure vessel. A gas is then dissolved under elevated pressure in the liquid substance or mixture of substances. The resulting liquid/gas solution is then conducted out of the pressure vessel and to an expansion element, through which it is passed and rapidly expanded. Upstream of the expansion element, in the expansion element or downstream, in particular just downstream, of the expansion element, a solid pulverulent auxiliary is admixed. In this manner, a stable pulverulent product results from the solution or from the substance or mixture of substances.
