    The objective of this research is to establish the optimum casting speed, number of operators, geared motor frequency that simultaneously minimize the percentage deviation of size and maximize the percentage of final use in the selection of fresh white asparagus . Design of central place with a total of 20 experimental runs were performed. The response surface methodology was used, analysis of variance test basic assumptions, fit testing the mathematical model, the desirability function using the EXPERT software DESING see 7.0. The conclusions that were obtained by using a design surface central composite response, optimum operating conditions are launched speed of 1550.82 kg / h; 9 online operators and a frequency of 42.0 Hz motor reducer which generate a final utilization of 85.43% and a standard deviation of 8.74% caliber. The quadratic regression model adequately the functional relationship rewrites casting speed, number of players and gear motor with frequency of use and the percentage deviation gauge, obtaining a high R2 (99.95% and 98.9%) and PRESS (1.54 and 0.11) in adjusted comparisons with other models. The point of multiresponse optimization that maximizes the overall desirability function (0.860) is when you have an advantage of 85.43% and a standard deviation of 8.74% caliber. Graphics optimization together with numerical optimization provide very good results for determining the point of optimization in multiresponse process optimization and particularly in the selection of fresh white asparagus and also the Desing-Expert 7.0 software see, is a powerful statistical tool in the process of multi-response optimization for speed in the calculation and a high representation in graphical environment.
