Optimization of rotation speed parameters and number of grinding wheels on the quality and production capacity of chicken feed pellets

摘要

This paper presents an experimental design approach for the optimization process parameters for the chicken feed pellets.To achieve this goal,the speed parameters and number of grinding wheels are selected and two levels of this parameter are considered.Design of expert(DOE)of tests was used for experimental design and analysis of results.The chicken feed ingredients mixture is formed into pellets using a grinding wheel pellet machine with a variation of 150,200 and 250 rpm rotation and variations in the number of grinding wheels 4,6,and 8 pieces.The highest pellet production capacity(26.2 Kg/hour)occurs at 200 rpm rotating speed and 4 pieces of grinding wheels.The highest engine efficiency(87.6%)occurs at 200 rpm rotating speed and 4 pieces of grinding wheels.The highest pellet durability(91.6%)occurs at 200 rpm rotating speed and 4 pieces of grinding wheels.Optimal machining parameters are recommended to produce a pellet production capacity response of 25.6 Kg/hour,85.53% efficiency machine,and 91.473% durability pellets are 150-225 rpm rotation speed range and 4-5 pieces grinding wheels.
