摘要
This work shows the early development of the vibrated trays dryer. The now of particles is controlled by vibration applied to them. The operating conditions of five springs;were determined and the best spring parameters were defined. The spring parameters selected were: shear stress equal 218 MPa and Hooke's constant, K equal 8540 Nim. The dryer was tested using coffee beans flowing into crossed currents with the processing air. The dispersion coefficient was determined using both the Taylor Dispersion Model and the Free Dispersion Model.
