HEAT AND MASS TRANSFER IN A VIBROFLUIDIZED BED OF VEGETABLE MATERIALS WITH RADIATIVE-CONVECTIVE POWER INPUT

Results are presented for theoretical and experimental investigations into the kinetics of dehydration and heat and mass transfer in a vibrofl uidized bed of vegetable origin materials using the example of potato and carrot particles in convective and radiative-convective heat inputs. A comparison has been drawn between calculation results and experimental data. The contribution of infrared radiation and convective heat fl ux has been determined. The possibility and regimes of dehydration process enhancement and reduction of its duration in a vibrofl uidized bed in radiative-convective heat input have been shown.
