Lisetskij V. Increase of efficiency of drying of a grain in dryers of periodic action

The object of researches is a grain, processes of drying and heating, grain dryers of periodic action.Methods of researches: There were used, at imple-mentation of theoretical researches the methods of theory of heatmassconvention, drying, mathematical design of techno-logical processes. Experimental researches were conducted in laboratory and production terms with the use of methods of planning of multifactor experiments and statistical experimen-tal data processing with the use of personal computer.Scientific novelty: distributing of basic parameters of drying process after length of drying highway at direct against motion of drying is described to the agent, got new analytical dependences for the calculation of process of drying in mine dryers, it is first offered and in theory technology of drying of grain in circulation dryers with the use of change of speed of moving of grain in every loop. The law of change of speed is certain. Estimation of influencing of parameters of process of drying is executed on the technological and structural indexes of grain dryers. Complex researches of kinetics of drying and heating of corn are executed. Got generalized crooked dryings and heating of grain in a layer. The basic results of researches are applied in indus-try. Branch of the implement is agriculture
