PROCESS FOR MANUFACTURING POROUS POLYSACCHARIDE PARTICLES AND PARTICLES THEREBY OBTAINED.

摘要

A process for manufacturing essentially spherical, porous particles of narrow particle size distribution, where a water solution containing one or more polysaccharides is being transferred onto a heated spinning disc, the temperature of which is continuously controlled, droplets of said solution are being ejected at the periphery of the disc, and said droplets are solidifying to particles during descent into a water catch, whereby the process takes place in an enclosure without opening and whereby no water vapor is added within said enclosure.
