Objective： Traditional dough preparation methods are complex and time consuming. They cannot guarantee constant good leavening quality as well. A new design of a fully automatic kneading and leavening machine has been proposed ; Methods： The design consists of five parts： the mixing system, the temperature regulating system, the container, the overflow detecting system, and the controller. The mixing system has two working modes, the intermittent mode and the continuous mode. The temperature regulating system controls the temperature of the leavening room. The container has Teflon coating. The overflow detecting system uses a resistance detector consisting of two electrodes. Overflow detection is accomplished by distinguishing the resistance between the two electrodes. The controller uses a single chip microcomputer to realize the full automatic control of the machine; Results： The machine can start up at a preset time, and full automatically operate. It also controls the temperature of the leavening room and avoid dough overflow. Instead of leavening control by time, it can control the leavening quality by controlling the times of the dough reaching the overflow detector; Conclusion： Experiments have demonstrated that the machine is cheap, easy to use, good at the quality of its output, and therefore deserved for popularization.
