“…Drying of crystalline hydrates in industrial conditions is carried out by the convective method in drum dryers [23,24], fluidized bed dryers [23]. A combined convective-radiation drying method [24] and a convective-microwave drying method in terms of radiation intensity of 350-400 W in a pulsed mode [20] are also used, which reduce the duration of the process, but lead to excessive energy consumption [25].…”
