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.

A method of producing microfine frozen particles, comprising: atomizing a mixture of a liquid and a gas and directing it toward a refrigerant liquid contained in a vessel so that paticles of the mixture may disintegrate into smaller particles because of the gaseous expansion of the gas in each particle and between the particles, and fall onto the surface of the refrigerant liquid substantially freezing the smaller particles in contact with the surface of the refrigerant liquid; making ripples on the surface of the refrigerant liquid by imparting kinetic energy thereto so that the frozen particles sink efficiency from the surface of the refrigerant liquid and, further, are prevented from adhering to one another to form a film; and, collecting the frozen particles out of the refrigerant liquid in the vessel for disposal outside the vessel.
