General description

Rotary flash dryer is a new high efficient fluidized drying equipment that we designed for solve the static drying’s low efficiency and high consumption problem.When designing the equipment,we combined the features of air stream drying and fluidized drying together.So the machine has reasonable structure and good performance,it really achieves the aim of low consumption and high efficiency of fluidzing drying.

This machine has a wide application scope,it can be used for drying in fire retardant,molecular sieve,rubber and plastic assistance,pesticide,pigment,dyestuff,pharmaceutical and part intermediate industries.

Working Principle

Hot air enters the stirring,crushing and drying chamber in a certain speed from the air inlet that at the bottom of dryer and produces vigorous eddy airflow.Material is acted by centrifugal force ,shearing force,impact and friction,the particle size of material becomes very small and mass and heat transmission is strengthened.At the bottom of dryer,big damp granules is crushed,small and low moisture content granules rise with the rotating air stream.During the rising process,the granules are dried further.Because of the rotary flow of air and solid,inertia of solid phase is higher than gaseous phase,the relative speed of air and solid is big,it strengthens mass and heat transmission,so drying intensity is high.
