摘要

The authors have given the results of numerical modeling and experimental study of the kinetics of dehydration, shrinkage of particles, and heat and mass transfer in a vibrofluidized bed of materials of vegetable origin with the example of particles of carrots and celery root with convective and radiative-convective supplies of energy. A comparison has been made of the calculation results and experimental data. A change in the qualitative indices of the product depending on the regime of processing has been established. The contribution of infrared radiation and of the convective heat flux has been determined. The possibility of enhancing the process of dehydration and reducing its duration in the vibrofluidized bed with radiative-convective stepwise in time energy supply has been shown.
