One of the promising directions of drying fruit and berry raw materials is the use of aerodynamic heating dryers, which implement the principle of transformation of electric energy spent on the drive of a centrifugal fan into thermal energy due to mutual friction of air flows circulating in a closed chamber. To reduce the energy consumption of the drying process, it is proposed to utilize the heat of the spent drying agent by equipping the dryer with a combined heat exchanger. The combined heat exchanger reduces the energy consumption of the drying process by reducing the energy consumption for heating the drying agent in the drying chamber. The presence of an air solar collector as part of a combined heat exchanger made it possible in this case to increase the temperature of the drying agent at the outlet by another 10 °C without additional electrical energy costs. At the same time, at the initial stage of operation of the dryer in the daytime, the drying agent is heated by the air solar collector of the combined heat exchanger.
