FIELD: food industry.

SUBSTANCE: invention relates to the food industry, namely the production of dry berries of shadberry. In the proposed method, the shadberry is dried in one layer by infrared rays at a temperature of 40°C by alternating vacuum and injection cycles, with two injection cycles and three vacuum cycles. In the evacuation cycle, the residual pressure is 6-6.5 kPa, and its duration is 90-120 minutes, and in the injection cycle, the overpressure is 30-40 kPa, and its duration is 4 minutes. In the injection cycle, dry air with a relative humidity of not more than 5% is injected into the chamber.
