Abstract
An apparatus having an XY-stage adapted to support base material, such as paper, and conduct two-dimensional moving thereof; a nozzle unit having three liquid droplet feeding nozzles adapted to feed separately liquid droplets containing a first shell material, liquid droplets containing a core material and liquid droplets containing a second shell material from above the base material so as to cause them to spot to the surface of the base material; and a drying unit adapted to dry the spotted liquid droplets to thereby form first and second shell films is provided.
Claims4
A process for producing microcapsule comprising:
- forming a first shell film by spotting a liquid droplet containing a first shell material to a base material;
- forming a core layer by spotting a liquid droplet containing a core material to the first shell film;
- and
- forming a second shell film by spotting a liquid droplet containing a second shell material to the base material so that the core layer is contained between the first shell film and the second shell film.
A microcapsule production apparatus comprising:
- first shell film forming means for forming a first shell film by spotting a liquid droplet containing a first shell material to a base material;
- core layer forming means for forming a core layer by spotting a liquid droplet containing core material to the first shell film;
- and
- second shell film forming means for forming a second shell film by spotting a liquid droplet containing a second shell material to the base material so that the core layer is contained between the first shell film and the second shell film.
A microcapsule sheet comprising:
- a base material;
- and
- microcapsules arranged at a predetermined pattern within a predetermined extent of the base material, the microcapsule being formed by surrounding a core layer with a first shell film and a second shell film.
A microcapsule sheet comprising:
- a base material being made of edible film or soluble film;
- and
- microcapsules being arranged at a predetermined pattern within a predetermined extent of the base material, the microcapsule being formed by surrounding a core layer with a first shell film and a second shell film.
