Abstract: A fish feed pellet was made by extrusion of the mixture of corn meal, deoiled soy flour and fish meal, the effects of process parameters on extrusion system was studied using regression orthogonal design, The three process parameters screw speed, solid feed rate and water feed rate were chosen as independent variables. The running current and running pressure were also used as dependent variables. Experimental design and regression analysis were carried out using regression orthogonal design. Two regression equations of running current and running pressure on screw speed, solid feed rate and water feed rate were established. The results show that all the chosen parameters influenced the running current and running pressure remarkably. There was also strong linear correlation relation between running current and running pressure. stability of the extrusion system can be forecasted and controlled using Running two regression equations established.
