Drying of medicinal plants is one of the important technological operations significantly determining the quality of the finished product. In this regard the development of energy-saving technologies of drying of raw materials is a priority. The article presents a drying unit of the disc type and the results of the studies. This approach allows us to dry evenly the different fractions of raw materials and efficient use of thermal energy compared with the conventional methods of drying.Данная работа выполнялась при поддержке гранта Президента Российской Федерации для государственной поддержки молодых российских ученых – докторов наук (МД – 5596.2016.8)
