Application of central composite design in optimizing the number and angle of pressure plates in the manufacture of pelleted chicken feed

The response surface methodology (RSM) is used in conjunction with Central Composite Design (CCD) to construct a mathematical model and improve process parameters in the manufacture of chicken feed pellets utilizing a rotating press plate pellet system. The impacts of two process parameters, namely the number of pressure plates and the angle of the pressure plates, were investigated alone and in combination. ANOVA determines the relative relevance of process characteristics in the production of pelleted chicken feed. The angle of the press plate is more important than the number of press plates in enhancing production capacity, pellet durability, and machine efficiency. The Design-Expert program was used to construct a second-order regression model for predicting engine parameter optimization. Three press plates and a pressure plate angle of 600 provide the optimal circumstances for producing production capacity, pellet durability, and engine efficiency.
