This publication presents the results of research on the innovative industrial technology of a cereal dryer in which a heat exchanger was used. Initial laboratory tests were used to determine the values characterizing the model installation work in the laboratory scale in order to verify the variables determining the selection of the most advantageous variant verified by cross-linking of dependent variables affecting the efficiency of the planned installation. Obtained results of research and analysis of variance of multifactorial experience in laboratory conditions, not affected by external factors introducing increased uncertainty of measurements, were supposed to provide information that would allow for selecting the type of exchanger liquid (the so-called thermal factor) circulating in the installation to receive and transfer heat and determine the optimal shape and the surface of the coil that fills the heat exchangers exchanged between air-liquid and fluid-air media.
