ABSTRACT
The vibrating conveyor dryer uses a flow form during operation, provides production automation, realises intensive infrared action in the fluidised product layer and produces an energy-efficient and constant flow for the process charge. This complex technological process is determined by certain factors: the coefficient of mass return, the mass of products, the speed of the conveyor belt, the size of the raw material particles, the moisture content, the coefficient of thermal conductivity, the volume performance of the process for the removed moisture, the specific temperature of the vapour and the amplitude of the oscillation of the wave propeller. The difficulty of working with such a large number of factors led to the application of the second similarity theorem and the introduction of a mathematical model of the criteria of Stanton, Froude and Burdo, whose magnitudes are reflected through the main factors of influence and were found experimentally. After using the ‘dimension theory’ and graph-analytic analysis of power functions, a criterial equation of the investigated process was obtained. This allows recommending the regime parameters and the design series of thermal radiation dryers with vibration-wave transport of products when varying the main factors of influence.
