Design and implementation of a multifactor control system for yuba production

Abstract

Currently, the conditions for yuba production are estimated manually. Therefore, this study proposed a multifactor control system using STC12C5A60S2 single-chip machine. For the high-efficiency production of yuba, the optimized production conditions of yuba were obtained through response surface analysis. First, the study designed the hardware and software components of the proposed multifactor control system. Subsequently, the test platform was established to test the effect of the slurry concentration, slurry temperature, slurry PH value, and slurry level. Finally, an orthogonal experiment was performed for response surface analysis, with the yield of yuba being considered as the response value. The results revealed that the control system was determined to exhibit excellent stability and small errors. The optimal yuba production conditions were a slurry concentration, slurry temperature, slurry PH value, and slurry level of 8.50%, 85.0 ℃, 7.0, and 27.5 mm, respectively, which were associated with a yuba yield of 47.91%.
