Airflow dryer is suitable for drying of starch and fine graininess materials, such as flour, cassava starch, gluten, flour additive, fish powder, distiller’s grains, forage and its powder, mineral powder, coal powder and sawdust etc.
■ Drying time is normally between 0.5s~5s, especially suitable for mate rials sensitive to heat damage.
■ High heat efficiency: since the material flows in the same direction as the drying air and drying time is limited, high air temperature can be used while the material itself is not over heated, thus, the heat effi ciency is increased.
■ Large drying capacity at big moisture reduction.
■ Simple structure, small space occupation and low initial investment.
■ Hot air source: any of oil fired furnace, gas fired furnace and steam heat exchanger.
