Study Notes
What is a Spry Drier?
A Spry drier, also known as a spray dryer, is a type of industrial dryer that uses hot gas to evaporate the liquid from a feedstock, producing a powder or dry particulate product.
Operating Principle
- The feedstock is atomized into a spray, which is then introduced into a hot gas stream.
- The hot gas evaporates the liquid, leaving behind a dry powder.
- The powder is then separated from the gas stream using a cyclone or bag filter.
Advantages
- Fast drying times
- Gentle handling of heat-sensitive materials
- Production of uniform particles
- High yield and recovery rates
- Low operating costs
Applications
- Food industry: production of milk powder, coffee powder, and fruit powders
- Pharmaceutical industry: production of powdered medications and excipients
- Chemical industry: production of powdered chemicals and catalysts
- Biotechnology industry: production of powdered biological products and enzymes
