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.

Method and apparatus for producing microfine frozen particles

A system for purifying gas in which one or more main adsorbers containing a gas-adsorbent comprising a molecular sieve carbon (MSC) or the like is connectable in series to a supplementary adsorber containing a substantially smaller amount of the gas-adsorbent in the range of from 5 to 50% of the adsorbent contained in the main gas-adsorbers. The main gas-absorbers are connectable in parallel so that when the gas-adsorbent in one of the main absorbers is being regenerated, and vice versa, the other main gas-adsorber can function independently to adsorb gas or can be connected in series with said supplementary gas-adsorber so that the purification of gas can be continuously effected while one or the other of the main gas adsorbers is being regenerated. The supplementary gas absorber, when connected in series with either of the main adsorbers, functions to effectively finish or substantially complete utilization of the gas-adsorbent in the main adsorbers so that the adsorbers are utilized to maximum efficiency during a minimal time interval.
