beet pulp

The article describes the results of experimental studies of the kinetic regularities of beet pulp drying by the filtration method. The influence of the main process parameters on the rate of moisture removal, including the height of the wet layer of material H (0,04 m, 0,08 m, 0,12 m, 0,16 m), temperature T (60 °C, 70 °C, 80 °C, 90 °C) and the velocity of the thermal agent v0 (1.24 m/sec, 1.76 m/sec, 2.29 m/sec, 2.82 m/sec), was investigated. The kinetic dependencies for the periods of complete and partial saturation of the thermal flow with moisture were derived.

The article presents the results of theoretical and experimental studies on the determination of the coefficients of internal diffusion of moisture from capillary-porous materials of plant origin during filtration drying, in particular, beet pulp, a by-product of sugar production.  A model based on the solution of the internal diffusion differential equation with the corresponding initial and boundary conditions were used to find the internal diffusion coefficient.
