description: The limiting section of the production line for post-harvest grain processing
is a grain dryer. The pace of harvesting and the quality of the functioning of the grain complex as a whole depend on the effectiveness of its work. Numerous studies in this subject area allow us to formulate the main groups of problems that arise during the operation of grain dryers. The first group: identifying ways to improve the design of the grain dryer, providing an increase in the efficiency of its work, taking into account the established restrictions. The second group: determination of the conditions ensuring the maximum efficiency
of the functioning of the grain dryer for given agrotechnical tolerances.
The main requirement for the design of the dryer is to ensure uniform exposure to the
coolant on the entire grain volume. The solution to the first group of problems is related to the rationalization of the design parameters of the grain dryer, and also provides for the intensification of the working processes of existing plants. The second group contains the tasks of optimizing the operational parameters of grain dryers, which are associated with
the problem of process control.
When analyzing the functioning modes of grain dryers, the influence of control parameters on various performance indicators is evaluated. In particular, for optimizing the technological modes, it is important to obtain the trajectory that the vector of output parameters
describes when the vector of input variables changes. An important step in solving the problem of optimizing operating modes and rationalizing the design parameters of a grain dryer is the development of its mathematical model and the formation of a system of restrictions.
