In the conditions of economic sanctions and food embargo in Russia, the issue of import substitution has become acute. Studies are becoming relevant, which improve the production process of hops. Currently, many enterprises use industrial dryers with high performance. The aim of the study is to increase the efficiency of drying hops with the maximum possible reduction of energy costs. The introduction of innovations should be preceded by an analysis of the existing technology of drying hops. Object of research - hop samples taken during and after drying, as well as an industrial dryer. Working measurements were carried out in threefold repetition. These included determining the temperature and humidity of the drying agent as well as the humidity of the hops. The results of studies have shown that it is possible to achieve significant energy savings in the process of drying hops. This is the scientific novelty. Based on the results, several ways to achieve savings are proposed. To do this, it is necessary to accelerate the movement of the mass of hop cones and optimize the ventilation system. On the basis of this, the possibility of modernizing the duct system to increase the productivity of the dryer is proposed.
