The process in which microcapsule's coating solidification is affected thermally

• Spray drying

• Spray congealing

• Pan coating

• Polymerization

Microcapsules having many cores enclosed within the shell is called

• Mononuclear

• Matrix type

• None

Which of the following technique include a physical method of microencapsulation

• Coacervation Phase Separation

• Solvent evaporation

• Multi-orifice Centrifugal Process

Which of the following technique include a chemical method of microencapsulation

• Coacervation Phase Separation

• Fluid Bed Coating

• Air Suspension Coating

• Multi-orifice Centrifugal Process

In which method, the particulate core material, which is solid, is dispersed into the supporting air stream, and these suspended particles are coated with polymers in a volatile solvent, leaving a very thin layer of polymer on them.

• Coacervation Phase Separation

• Solvent evaporation

• Air Suspension Coating

• Multi-orifice Centrifugal Process

• Coacervation Phase Separation

• Solvent evaporation

• Air Suspension Coating

• Multi-orifice Centrifugal Process

Solid particles to be encapsulated are suspended on a jet of air and then covered by a spray of the liquid coating material. when the spray nozzle is located at the bottom of the fluidized bed of particles, the process is known as

• Fluidized bed microencapsulation

• Wurster method

• Spray drying

• Spray congealing
