Complex Granular Flow Dynamics in Fruit Powder Production Lines

Abstract

One of the most important parts in every industry, is packaging which is located at the last part of the product line. In fruit powder product line lots of studies applied to study the complex dynamics of the powders in response to the vertical vibration. In this study cyclone collector condition was simulate with a rectangular throw out bin and the dynamics of the powders in response to the horizontal vibration studied. An ADXL345 accelerometer does employed in order to observe the acceleration of the system in all three dimensions. In order to have better observation two hollow cylinder was added to the container. At the peak values of acceleration, novel swirling granular flows were observed in the cylinders while the grains cascaded down the outer surface of the piles that formed outside the cylinders. An image processing algorithm employed to make a surface scan from the top surface of the material. Computer simulations were performed that supported our interpretation of the dynamics observed in the experiments. And a comparison between the image processing algorithm and computer simulation evaluate our simulation results
