The most common methods of drying of horticultural raw materials involve processes when raw materials are in an immediate contact with the heated air or superheated vapor and contact methods when the heat is transferred to the product via the surface heated by a technological agent. A low efficiency of utilization of energy resources and relatively low quality of the end product are the disadvantages typical for these methods. We investigated the influence of electroplasmolysis by bipolar pulses and fractional juice separation before drying with the aim to increase the efficiency of drying of horticultural raw materials. The dynamics of the drying process (Fig. 1, curves 1 - 3) shows that without application of electroplasmolysis by bipolar pulses (curve 1) the normalized moisture value can be attained after 35 hours; with electroplasmolysis and juice separation (22%) the normalized moisture value can be attained within 15 hours. Hence, application of bipolar pulses with fractional juice separation provides a substantial acceleration of subsequent drying and is promising for optimization and increasing of the process efficiency.
