Development of energy efficient drying regime of starch-containing raw material




sweet potato roots, heat and moisture treatment, step drying, chips, food powder, energy-efficient regimes


The article gives the classification of plant materials, focuses on starch-containing raw materials, in particular, sweet potato roots, chemical composition, existing drying methods. The results of studies of heat-water treatment and the process of convective dehydration of root crops are presented. Energy-efficient two-stage drying modes have been developed, in which the coolant temperature in the first stage of the process is 80 ... 100 °С, in the second – 55 ... 70 °С, the material temperature during dewatering 50 ... 60 °С. reduction of drying time, reduction of heat losses to 15 %, production of dried products with high organoleptic characteristics
