Abstract
Abstract A method for encapsulation of a liquid or meltable solid material, comprises the steps of forming a jet of a material to be encapsulated, simultaneously forming a coaxial jet of a capsule-forming material surrounding the jet of the material to be encapsulated, forming a coaxial jet of a heated circulating liquid surrounding the coaxial composite jet of the capsule-forming material and the material to be encapsulated, introducing the resultant coaxial triple jet into a flow of a cooling liquid to form capsules composed of a core of the material to be encapsulated and a capsule or coating film of the capsule-forming material. The heated circulating liquid has a temperature close to or higher than that of the capsule-forming material.

Claim 3
Independent Claim
181 words
An apparatus for encapsulation of a liquid or meltable solid material, comprising a jet-forming assembly for making a coaxial composite jet of at least a material to be encapsulated and a capsule-forming material, and a capsule-forming cylinder arranged beneath the tip of the jet-forming assembly, into which a cooled circulating liquid is introduced to form a flow of a cooling liquid, characterized in that said jet-forming assembly comprises an inner nozzle for making a jet of a liquid or meltable solid material to be encapsulated, a middle nozzle coaxially arranged around said inner nozzle for making a coaxial jet of the capsule-forming material surrounding the jet of the material to be encapsulated, and an outer nozzle coaxially arranged around the middle nozzle for making a coaxial jet of a heated circulating liquid surrounding the composite jet of the material to be encapsulate and the capsule-forming material, and that the outer nozzle is connected to means for supplying a cooling liquid as the heated circulating liquid which is kept at a temperature close to or higher than that of the capsule-forming material.
