RMANNCO, INC. is the Exclusive, Worldwide Licensee to "Pioneer" Microencapsulation Technology
Microencapsulation methods are separated into two categories: Chemical processes and physical processes. Examples of chemical microencapsulation processes are centrifugal force, complex coacervation, in situ polymerization, interfacial polymerization and polymer-polymer incompatibility. Examples of physical microencapsulation processes are spray-drying and spray-cooling, fluidized-bed coating, extrusion/centrifugal extrusion, liophylization, and co-crystallization. Modifications of these methods include coacervative spray, polymeric phased-separation, laser-pulsed-drop column, etc.
Typical microencapsulation processes with their relative particle size ranges are presented below:
Microencapsulation process Particle sizes in μm (micrometers)
Fluid bed coating 20–1500
Rotating disk 5–1500
Solvent evaporation 0.5–1000
Phase separation 0.5–1000
Interfacial polymerization 0.5–1000
Mini emulsion 0.1–0.5
Sol-gel encapsulation 2–20
Layer-by-layer (LBL) assembly 0.02–20
(Resnick) Coplanar Annular Encapsulation
RMANNCO's proprietary method of microencapsulation is well suited for encapsulating biologicals, pharma's, flavorings, probiotics, pigments, paints, etc., and can be engaged at any point along the production line to reduce production costs (sieving, drying, etc.), eliminating costly processing steps, and help to increase product quality and profitability.
