A mixer control device having a function of a monitoring device acquires measurement data of monitoring target information that is obtained through measurement when a rubber material is kneaded by a mixer. In addition, the mixer control device compares the measurement data and reference data that is selected in past measurement data of the monitoring target information and performs abnormality determination. The mixer control device acquires measurement data that is measured from predetermined mixing operation initiation timing in a series of mixing operations of a rubber material in the mixer for every unit of the series of mixing operation.

The measured value of a rubber temperature parameter that is related to the temperature of a rubber material to be kneaded by a mixing machine 2 and measured values of correlation parameters that have a correlation with a change in the value of the rubber temperature parameter are acquired. The measured values are assigned to an operational control parameter-calculation model equation, which is modified from a rubber temperature parameter-calculation model equation including operational control parameters and the correlation parameters, and a constant and coefficients of the operational control parameters and the correlation parameters are calculated using a machine learning algorithm. A predetermined operational control parameter, which is required in a case in which the rubber temperature parameter is controlled to a predetermined value, is calculated using an operational control parameter-calculation equation that is specified by the coefficients and the constant calculated using the machine learning algorithm.

The present invention relates to a mixing apparatus. A production unit produces a working fluid that is in a supercritical state or a subcritical state. A storage unit stores a material. A dissolving unit dissolves the material in the working fluid. A mixer mixes the material together in the presence of the working fluid. A material feed valve opens or closes a flow passage through which the material is to pass to be fed from the storage unit into the dissolving unit. A working fluid inflow valve opens or closes a flow passage through which the working fluid is to pass to flow into the dissolving unit from the production unit. A mixer inflow valve opens or closes a flow passage through which the working fluid and the material are to pass to flow into the mixer from the dissolving unit.
