INVESTIGATION OF THE BEET PULP FILTRATION DRYING KINETICS

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. This allows us to describe the change in the material moisture content and duration of the filtration drying process. Verifying of the accuracy of the obtained dependencies presents a maximum relative error of 36.54 % and an average deviation of 8.46 %, which is acceptable for practical calculations of drying equipment.
