BACKGROUND: The solving of priority tasks for the development of the agroindustrial complex considers the creation of advanced scientific developments. Innovative research of technical means and technologies of mechanization of agricultural production is not an exception in this regard. In the agricultural sector of Russia, crop production occupies a key place, in which the cultivation of grain crops is a priority. In the whole range of operations in the production of grain, the most important part of it is postharvest processing of grain. One of the main stages in the postharvest processing of grain is drying, in which the raw materials are brought to the moisture regain (down to 14%). Proper preparation of grain for storage ensures its reliable safety. AIMS: Modernization of the granular materials dryer by means of new technical solution at the level of patentability. METHODS: Research of the state of the issue on the topic under consideration with the help of a review of literary sources. Patent search for technical devices of grain dryers. Studying the principle of their functioning and design features. Analysis and generalization of the material for the adoption of a new design solution. RESULTS: The use of innovative technologies with the new generation harvesters, characterized by high productivity, has significantly reduced the duration of harvesting, and this, in turn, has significantly aroused the interest in drying. The use of dryers with improved quality indicators of functioning significantly reduces the time for preparing raw materials for long term storage, reduces grain losses in the field during harvesting, and, in addition, makes it possible to carry out the process of transferring grain from the field to a special longterm storage warehouse in the shortest possible time and with the least losses. There are various ways of drying granular materials. These are main methods based on increasing the temperature of the processed material. Drying of grain with the help of heated air has become the most widespread. CONCLUSIONS: As a result of the conducted research, the drawbacks of existing technical devices for granular materials drying, as well as the principles of their functioning, have been revealed. A detailed analysis of literary sources, including a patent search, made it possible to upgrade the processed raw materials dryer, characterized by a simple and reliable design.
