Development of Smart Stirred Machine for Vinegar Solid-State Fermentation Using Embedded System and Cloud Computing Server

Through the analysis of the functional requirements and working schedule of the grains-stirring machine, an intelligent system has been developed for solid-state fermentation in this paper. Firstly, the embedded system for stirred machine is designed, which includes power-supply module, motor-derived circuit, proximity sensor, temperature sensor, 2.4G wireless and GPRS module etc. Then, a cloud computing server platform is presented to monitor the working process and the quality of fermentation. The communication between the cloud computing server and stirred machine is GPRS. The experimental result demonstrates the performance of the developed system. Furthermore, the system increased the automatic cleaning and crushed-material design, avoids caking and over-fermentation, and improves the efficiency and quality of stirred vinegar cultural.
