The kinetics of drying sugar beet parenchyma tissues treated in a pulse electric field are studied in this work. During the drying process the following dependences were obtained: the material specific humidity vs. time, the drying rate vs. material specific humidity, the material temperature vs. material specific humidity. The influence of preliminary treatment of the parenchyma tissues of sugar beet roots before the extraction in a pulse electric field on the drying process was investigated. It is shown that the electrical treatment exerts a positive action on the internal mass transfer, which defines the kinetics of drying. If the regime and the process of the electric treatment are efficient, the drying duration can be significantly reduced.
