The experiments show that the PS and PSD of particles produced by SAA process can be controlled by adjusting process parameters, and among them, the pressure of the saturator used has the most effect on the PS and PSD, while the temperature of the saturator has the least effect. When using ethanol as solvent, the optimum operating conditions of using SAA process to produce erythromycin micro-particles from erythromycin-ethanol-CO2 system were found as follows. The pressure and temperature of the saturator are 10.5MPa and 70℃, respectively, the inlet flow rate and the concentration of inlet solution of the precipitator are 9 mLmin^(-1) and 15mgmL^(-1), respectively.

First, for a given integer value of the objective function, the lower and upper bounds of the variables were determined by the optimum simplex tableau of the linear programming relaxation problem. Then the conditions on the bounds were added to the constraints as cuts to the associated objective function hyperplane. Finally, a branch procedure of the branch-and-bound algorithm was applied to finding a feasible solution on the objective function hyperplane.
