Abstract: Determining the consistency of a mixture during a mixing process based on feedback from the mixer. The feedback may be indicative of the torque exerted on a motor shaft of the mixer. The consistency of the mixture may be determined based on the amount of torque, rate of change of torque, change in the rate of change of torque and/or a comparison of the torque information to a stored torque profile. The torque may be determined based on the current in the coils of a motor of the mixer (e.g., by measuring the voltage across a precision resistor in series with the coils). Alternatively, the feedback may be indicative of the angular velocity of the motor shaft, sound output by the mixer, vibration of the mixer, color of the mixture, or opacity of the mixture.
