摘要： A drying method for liquids is provided in which the liquid is sprayed, together with a gaseous fluid such as steam, into a lowpressure zone to cause freezing of the liquid in small particle form, and the frozen particles are then freeze-dried. The liquid may be a bioliggical solution, fruit juice or tea or coffee extract. An apparatus is also provided, comprising a freezing chamber, a two fluid nozzle simultaneously spraying liquid and gas into the chamber, a vacuum system with condensers for maintaining a low pressure within the chamber and a freeze-drying chamber.
