Abstract: In order to improve the smoothness of double-pan roasting machine and reduce the noise, the key parameters of the crank rocker mechanism of the double-pan roasting machine were optimized. The mathematical model designed for the double-pan roasting machine was set up and optimized. The objective function was to maximize the minimum transmission angle. The optimized design program of double-pan roasting machine based on ant colony algorithm was compiled with Matlab, and the optimization calculation and verification experiment were carried out with this program. The optimization results show that the lengths of crank, connecting rod, rocker and rack rod were 200βmm, 333βmm, 310βmm and 320βmm, respectively. The minimum transmission angle was increased from 14.6 to 21.1, and the noise was reduced from 75βdB to 70βdB, the forming rate of gunpowder tea increased from 84% to 92%. The rate of broken tea decreased from 8.6% to 7.2%. This research provided a theoretical basis for improving the performance of double-pan roasting machine.
