Experimental optimization and analysis of drying in ifrasound dryer

Abstract: In the agricultural industries drying plays a major role as its very important for grain storage. The selection of the dryer and the method used for drying should be chosen wisely considering the product to be dried with its other factors. Generally, a dryer and its method are taken into account based on the output product quality and considerable energy consumption given during drying. This thesis is based on finding out the optimal energy consumption obtained while drying the wheat grain using the integrated infrasound technology through conducting experiments and analyzing the process of drying with the CFD model. The thesis work covers physical experiments, determination of the relation between infrasound parameters, and evaluation of the drying in CFD simulation, to analyze the drying process. The experiments are done to predict the relation between the drying and the other main parameters like sound frequency, sound pressure, piston displacement, cycle time, and the airflow rate. The experiment procedure and requirements are clearly formulated accordingly. The experimental results are later compared with the theoretical data to check the expected output. The dryer capacity varies with the cycle time, temperature, and sound wave. The CFD simulation is executed to study the air flow velocity, temperature and the fluidization condition of the particle. To compare the energy consumption of the drying system a conventional air dryer is selected here. The results of this study show that infrasound-integrated technology has a relatively low energy consumption, but will have a high cost for installation and maintenance.
