The Effect of the Distance between the Nozzle and the Conveyor Belt on the Internal Flow Field of a Rapid Freezer
Optimizing the structure of the quick freezing machine can effectively improve the efficiency of quick freezing.The Y-shaped nozzle tunnel freezer was taken as the research object,and COMSOL software was used to establish physical models of three Y-shaped nozzles.By changing the distance between the nozzle and the conveyor belt as a single parameter for simulation,the influence of the distance between the Y-shaped nozzle and the conveyor belt on the internal flow field of the freezer was studied.Through simulation,it was found that the distance between the Y-shaped nozzle and the conveyor belt mainly affected the variation of wind speed in the direction of the jet.When the distance increased,the surface heat transfer efficiency of the mesh decreased.Shortening the distance between the nozzle and the conveyor belt according to the size of the frozen product can effectively improve the efficiency of quick freezing.
