  • Patent number: 11052360
    Abstract: A mixing machine includes a head extending over a bowl receiving location, the head including a downwardly extending rotatable output shaft for receiving a mixer tool. A drive train including a motor having an output operatively connected to drive a planetary gear system that effects rotation of the rotatable output shaft about its axis and orbiting of the shaft axis about another axis. A control system includes a master control unit and a slave control unit, the master control unit connected with a first sensor located along the drive train between the motor and the planetary gear system, the slave control unit connected with a second sensor, wherein both the slave control unit and the second sensor rotate with a part of the planetary gear system, wherein the master control unit and the slave control unit are configured for wireless communication with each other.

  • Patent number: 10743550
    Abstract: A mixing machine includes a head extending over a bowl receiving location, the head including a downwardly extending rotatable output shaft for receiving a mixer tool, the head including a planetary system therewithin for effecting rotation of the rotatable output shaft about its axis and orbiting of the shaft axis about another axis. A motor includes an output operatively connected to drive the planetary system. A control system includes a plurality of sensors, each sensor located for detecting a respective condition of mixing machine, and a diagnostic control operable to (i) track outputs from the plurality of sensors over time, (ii) analyze the tracked outputs and (iii) produce an alert indication based upon the diagnostic control identifying a performance characteristic indicative of a need for service or repair of the mixing machine.

  • Publication number: 20180085966
    Abstract: A food slicer for slicing and weighing food items includes a slicer body and a slicer knife mounted for rotation relative to the slicer body. The slicer knife includes a peripheral cutting edge. A food product carriage is mounted to the slicer body for reciprocating movement back and forth past a cutting zone of the slicer knife. A portion scale is mounted on the slicer body and includes a weigh platter on a slice exit side of the slicer knife. A controller of the food slicer is configured for automated operations and/or monitoring and alerting based upon slicer conditions.
