01. Experimental/Computational Fluid Dynamics

In recent years, industrial technology has made a significant contribution to the large-scale production of food products, labor saving in the cooking process, and food preservation. For hygiene management, it is essential to clean the surface of the equipment that comes into contact with the food of the machine used in this food processing or the like. In addition, as processing machines become larger in size and more complex in internal structure, advanced cleaning technology that aims for higher cleaning certainty and operational efficiency is essential. Given the above background, using CFD (Computational Fluid Dynamics), we will proceed with efficient cleaning using cleaning nozzles and verification of appropriate nozzle placement. However, although the current CFD can simulate the cleaning process, it is difficult to quantitatively evaluate the food soil that is cleaned over time because there is no reasonable mathematical model to represent the food soil and the analysis cannot show the detailed cleaning process. Therefore, the purpose of this study to research and develop an analytical mechanical-mathematical model of food soil using the Discrete Element Model. In previous symposium at Kumamoto, Japan, we reported on the results of analyzing the exfoliation of food soils using a straight nozzle. After that, to make the exfoliation of food soil closer to the actual phenomenon, we increased the number of nozzle types used in the analysis and conducted the analysis using not only straight nozzles but also rotation nozzles. The results of the analysis of the exfoliation of food soil when each nozzle is used are presented in this symposium.
