Abstract
A method of producing microfine frozen particles from water, liquid drugs, juices, etc. comprises the steps of atomizing a mixture of a liquid with a gas and directing the mixture toward a body of a refrigerant liquid whose surface is stirred by application of kinetic energy to form ripples. The refrigerant liquid being liquid nitrogen, liquid air, a cooled organic solvent or the like, so that the atomized liquid undergoes heat exchange with the refrigerant liquid to form fine frozen particles. An apparatus for practicing the method, comprises a vessel for containing the refrigerant liquid, apparatus for forming ripples at the surface of the refrigerant liquid by injecting a gas, or by applying vibrations to the vessel or the refrigerant liquid, an atomizer functioning as a mixer and atomizer for a liquid and a gas, and an apparatus for collecting the microfine frozen particles from the refrigerant liquid.
