The drying and heating system (DHS) is the core component of automatic stirring equipment, so analyzing its thermodynamics is crucial for improving the efficiency of the equipment. However, existing empirical thermodynamic formulas generally take certain working conditions as prerequisites, and substituting relevant parameters of DHS into calculation can cause large errors. In view of this problem, this paper attempts to perform thermodynamic analysis and calculation on the DHS of automatic stirring equipment. At first, the material ratio of the automatic stirring equipment was analyzed in the text, and the drying and heating process of mixture was divided into three stages: mixture preheating, mixture drying, and heating mixture to the working temperature. Then, the heat consumption of DHS, the heat consumption of fuel combustion, the consumption rate of the fuel, and the heat efficiency of DHS were measured and calculated. At last, the thermodynamic analysis results of DHS of automatic stirring equipment were given, and the measurement and calculation methods adopted in the paper were proved to be effective.
