Abstract

Encapsulated solids are made by first encapsulating precursor materials in a polymer shell. The precursors are some combination of solids, liquids, gases, and/or gels. The precursors are then transformed into solids by emplacement of the capsule in an environment where gas or fluid transport into or out of the polymer shell causes transformation into solids.

Claims (13)

1. A method of making a capsule containing an encapsulated material, comprising the steps of:

providing an outer tube,

providing an injection tube inside of said outer tube,

providing an inner fluid of precursor material in said injection tube wherein said step of providing an inner fluid of a precursor material comprises providing an inner fluid of concentrated sodium carbonate solution precursor material,

providing a droplet forming nozzle inside of said outer tube wherein said droplet forming nozzle is connected to injection tube,

providing a collection tube inside of said outer tube wherein said collection is positioned proximate said droplet forming nozzle,

providing middle fluid polymer encapsulation material inside of said outer tube and outside of said injection tube and said droplet forming nozzle,

providing outer fluid inside of said outer tube and outside of said middle fluid polymer encapsulation material wherein said outer fluid produces a boundary layer with said middle fluid polymer encapsulation material,

moving said inner fluid of said precursor material in said injection tube and through said droplet forming nozzle producing droplets of said precursor material,

moving said middle fluid polymer encapsulation material inside of said outer tube and inside of said outer fluid around said droplets of said precursor material encapsulating said droplets of said precursor material in a shell of middle fluid polymer encapsulation material,

providing a vacuum dehydration unit, and

emplacement of said droplets of said precursor material in said shell of middle fluid polymer encapsulation material in said vacuum dehydration unit where said precursor material is transformed into a solid.

2. The method of making a capsule containing an encapsulated material of claim 1 wherein said step of emplacement of said droplets of said precursor material in said shell of middle fluid polymer encapsulation material in said vacuum dehydration unit comprises emplacement of said droplets of said concentrated sodium carbonate solution precursor material in said shell of middle fluid polymer encapsulation material in said vacuum dehydration unit where said precursor material is transformed into a polymer-coated sodium carbonate solid.
