Abstract
The quality of medicines required in modern conditions determines the high requirements for the composition of each component of bulk materials and the strict implementation of the recipe of the final product with the required accuracy. A prerequisite for the products is the operational reliability of the equipment with an increase in the level of automation and ensuring the safety of production and comfortable working conditions of personnel. The preparation of medicines poses the task of organizing the production process with fewer pieces of equipment, a shorter length of transport lines and, accordingly, a reduction in energy consumption. The article presents the relevance of the study and classification of medicines. The principle of operation of a screw weighing dispenser for the pharmaceutical industry as a control object is described. A mathematical model of a screw device for dosing bulk materials of the pharmaceutical industry has been developed.
