Review and analysis of grain chillers to create more advanced machines

Abstract

The development of agricultural production these days involves an innovative approach to solving complex problem of the agro-industrial complex. The most important direction of mechanization of grain processing is the development of coolers operating at a qualitatively new level. To create the basis for the improvement of such devices, a review and analysis of grain chillers were performed. Scientists have investigated the process of chilling grain in a dense layer, vibro-liquefied layer and under the air flow. Indicators of quality of the chillers were defined. Theoretical relations describing these processes were found. Positive and negative characteristics of the devices providing their functioning were revealed. Indicators of quality of work of devices for cooling of grain are defined. Found theoretical relations describing these processes. Positive and negative characteristics of the devices providing their functioning are revealed. The intensification of the heat exchange by increasing the speed of air flow around the grain was considered as a most effective method.
