The search for resource-efficient and environmentally friendly technologies and technical solutions in the field of food production should be carried out by creating and improving new analytical approaches and constructive solutions, which will contribute to the development of the industry not only within the state, but also at the international level. Rational use of production capacities of processing enterprises is traditionally accompanied by a high level of their mechanization.

Drying is one of the most common technological processes in the processing and food industry, in particular during the preservation of raw materials. Further development of drying technologies is aimed at reducing energy consumption in the process of moisture removal, improving the quality of finished products, creating highly efficient universal equipment and ensuring environmental safety of drying production.

When studying various physical phenomena in the process of vibration drying, two research methods are used, which allow obtaining quantitative patterns. The first method uses experimental research of specific properties of a single phenomenon, the second - proceeds from the theoretical study of this problem. The advantage of the experimental research method is the reliability of the results obtained.

The paper analyzes literary sources and substantiates the need and possibility of creating new designs of dryers using infrared effects on the product and vibrational oscillations of the working container to intensify the drying process. The proposed design solution of an experimental laboratory drying plant for drying granular and granular materials in a vibrating fluidized bed allows identifying patterns of changes in the parameters of the drying process, obtaining data for process optimization and for developing a methodology for engineering calculation of devices for infrared drying in a fluidized bed.
